  1. @Luke K P @Julien Recan please read my prev article on this if you haven't >> https://carnity.com/forums/topic/16736-diff-lock-simplified-center-rear-front-explained/ The Standard Order is Central Diff Lock > Rear Diff Lock >> and last Front Diff Lock. Am sure there's a very technical reason for this, one involving blowing out diffs, but for shortcut let's just say this is how it's done in Mercedes G-Wagon and Toyota Land Cruiser 80, so let's follow Mercedes & Toyota engineers regarding this order of pressing the buttons Here's my take on your new orange Ford: 1. First check if your Center + Rear Diff Locks are automatically engaged when you switch to 4Lo. My Nissan Y62 Patrol did this, everytime I turned 4Lo, it automatically enganges Rear Diff Lock (thus also Center Diff Lock). My Jeep Grand Cherokee doesn't do this, so if I go 4Lo, it doesn't engage any diff locks. How to test? You can't test on sand. In your parking space, turn on 4Lo then move forward 3 steps so it fully engages 4Lo. Then turn your steering wheel full-left (or full-right) and accelerate. If your tires are slipping or you hear screeching sound, means your rear diff is locked. Remember the purpose of Differential is so that left tyre and right tyre can spin at different speeds (which is needed for turning full-left/full-right mechanism) 2. If #1 doesn't make any sound means you are in 4Lo but in open diffs mode (no center and no rear diffs locked). Great, you can drive in 4Lo at high-speed to get more torque. 3. Why would you ever want to drive with diff locks engaged at high speed ??? Read Point #1 above, the purpose of having differential is to allow left-tyre to spin faster/slower than right-tyre, which is needed for full-turn. Yes in low-traction platform like soft sand and water, the tires still slip but they will not screech and make sound like in your concrete car parking or highway asphalt. But still, do you want to risk it? Example: you're riding on a ridge with soft sand with Center + Rear Diffs locked, then suddenly you have to make 90-degrees left-turn to exit the ridge riding. If the sand is hard (due to rain), now you're turning on a non low-traction platform. The tires will slip to make the turn, but because you're no longer in soft sand, you will be turning like a Rally Driver, with that drifting effect, which is fine on horizontal levelled plain areas (sabkhas), but on a ridge? Only the braves will risk it.... I've asked some "crazy" drivers why they turn-on Center Diff Lock when driving, and these are their reasons: 3.1.They want to drive in a STRAIGHT LINE very fast. Rally drivers do this. You can also try when you're climbing up in a straight line, but not when you're going up then decided to make a loop. 3.2 They want to drift when they're side-sloping, only doable with beadlocks. I've seen this in front of my eyes: so the car looks like fighting gravity, but in fact they are SLIDING horizontally with the nose facing 45-degrees up. Very cool for videos, but even I don't want to try that πŸ˜‚ PS: we can do a 30-mins "testing session" after an official drive to test the various modes of your mighty Raptor 😁

  3. hi @RiadJL each scenario is different, tag me if you're joining next Iftar Bowl drive and will be happy to check your various configuration. But please go through these first before jumping to diff lock: 1. Lower your psi. I had trouble climbing some parts of Lady Dune, but was able to climb after deflating all tires to 10 psi. Of course if you don't have thick sidewalls, safest is to stick to 12 psi (now you have a reason to get taller tires that have "70" or "75" in the middle like 265/70/17) 2. Try in 4Lo but higher gears (e.g. 4Lo + 3rd gear or 4Lo + 4th gear). This will give you lots of torque but also some speed. 3. If you're tires are jumping in the air and the terrain is bumpy, you need firmer shocks (which is perfect for offroad and bumps but too stiff for daily driving). 4. If 1+2+3 above are done but still "no power", you can try Center Diff Lock only 5. If 1+2+3+4 above are done and still "no power", allow me to drive your car. 6. If 1-5 are done and still "no power", let's discuss buying another car

  4. Thanks @Zed. Indeed I have checked that sand mode (4H) does engage rear difflock right away. Can turn it off and keep it off. 4L does not automatically switch it on.. 4L becomes manual on and off. Given your descriptions above.. think maybe the 'sand mode' ( 4H + diff lock ) is aimed at american baja type flat sand desert driving rather than up and over of dunes.... ie lots of drifting on fairly level ground. yeah the cresting whilst turning over it @Julien Recan left me thinking about this all weekend.

  5. Thank you @Gaurav and @Vijay Vaidya, looking forward to it. One of the reasons they close certain terrains or trails is due to the public not being aware of Tread Lightly principles. Happy to pass on knowledge I've learned over the years. We conduct 9 hours of guide work in the mountains to teach Members to grow and develop leadership skills under pressure. I have found it's the best way to grow the offroad community, and keep Members safe. Until then... I'll keep roaming around this forum, just got full access. Thanks for the warm welcome.

  6. Dear Jerome, Thank you for organising such an exhilarating & safe drive on Saturday. While crossing the 'blue Jeep' bowl brought back fond memories of my old blue Jeep Wrangler. I'm also grateful for giving me the opportunity to sweep the convoy. It was an interesting experience. Looking forward to our next drive. Thank you to all the fellow drivers for the support. Thank you for capturing and sharing the exciting moments.

  8. Interested to see if recovery kits vary for the desert troopers... coming from a rock crawler background... we have trees and large boulders that give us an advantage to use our winches during recovery. What does your recovery kit include, and why? What are the most common recovery strategies you have found on the dunes? My Personal Recovery Gear includes: 3 snatch blocks with synthetic shackles light weight aluminum style pulleys 1 steel snatch block 2 aluminum shackles 4 soft shackles 1 long soft shackle 2 tree savers 2 chafe guards 2 line dampeners Kinetic recovery rope Tow straps Fast fid rope (rope splicing tool) Gloves (we use gloves at all times, I have had to recover someone's finger off a trail to the hospital/assist with a Member that accidentally spliced their finger too) Hand-held GMRS radio Well-functioning winch/winch controller/free pull available & synthetic line

  9. Hello, Moving to Dubai in a couple of months, and with that anticipation, looking to find a new home in the offroad community. I have 8 years of experience and volunteer as a Trail Guide to assist others and build their knowledge. Most of my experience is rock-like terrain, therefore dunes will be a new adrenaline rush. Looking to meet new people and make some friends in the industry, eventually get into racing... Since Dubai will be new to me... any recommendations on where to start?

  11. @Zed this is exactly what happened when I was cross-crossing. The back just slid when I tried to cross and ended up crested. i (unwillingly, thought it was sensor issue) drove for 30 mins with rear diff lock on and while its not totally unmanageable, I clearly noticed the back was sliding a lot more anytime I was turning sharply. @Luke K P not sure how that compares to your experience, but from mine, I can’t really think wranglers are meant to be driven with it on 😁

  12. Thank you @Gaurav for the technical and fun drive - we touched so many types of dunes and terrains, it was a great learning experience. Special shoutout to @Benjamin for his patience and skills, I learnt a lot just by watching him and listening to his instructions on the radio, and to @Sviatoslav for the amazing pictures!

  13. Hi @TheGuardianJLU welcome to Carnity and its off-road club, I am sure you will enjoy it here in Dubai, as it offers great outdoor exploration with varied terrain around the country. Desert and sand experience is a lot less intense than rock-crawling but equally exciting and filled with adrenaline and a lot more forgiving than mountains. UAE has more sand and less of mountains now, as most rocky-terrains are either restricted or converted to sedan-friendly drive. We do host overlanding and mountain scenic drives occasionally, where you can enjoy the home-like feel and also we can learn more from your vast experience heading the Nova Jeepers (nicely organized club).

  19. Normal shovel. This is basically our most useful tool in desert driving. In 95% of recovery situations in the desert, a sturdy shovel will get you out. I know in the US winches are used along with tree straps etc to self-recover. Winches aren't very prevalent here as a self-recovery tool since we very rarely have something to strap on to in the desert. Land anchors for sand tend to be large, heavy and impractical and I've only ever seen a handful of people with one There are quite a few people who have winches on their rigs here but they are mostly used to help recover someone else

  20. Just a regular shovel. it is used to remove sand from under the car. Mine is AOR extendable shovel. I disassemble it into 3 pices and store it in the bag with ropes. I find it nice and tidy. While it is not large but it does work most of the times. Ideally you want to get one with a long handle so that you can reach underneath the car from all directions.

  21. @Looper it seemed in those straight stretches at fast pace when the convoy was spread out I could not hear you at the back , unless we were taking bends . I tried both radios Crony and Baofeng same result. There was also multiple times @Imran Asghar radioed and we could not tell if there was a response.

  28. @Luke K P @Julien Recan check out this recent Dakkar Rally "amazing shot" video, the car is "fighting gravity" on a side-slope. Center Diff Lock + Rear Diff Locks will help here: Center Diff Lock will ensure both front axle + rear axle spins at same speed. 50-50, not 40:60, not 30:70. 50:50 means better traction because if your rear tires are slipping, front tires still have 50% power to pull (assuming the sand allows it). Rear Diff Lock will ensure rear-left + rear-right tires are always spinning. What if you hit a small stone and your rear-left tire is in the air? Without rear-diff-lock, this tire in the air will spin and the tire on the ground will stop spinning (at least momentarily until all tires land on the sand again). BUT this driver has to go down in a controlled manner and not full 90-degrees down.

  29. Interesting.. I haven't been able to climb up Iftar bowl's center face so far. My impression was the wheels spend too much time in the air because of all the tire tracks in the sand there and so I'm not able to put down enough power. Do you think diff locks would help in this case? or sway bar disconnect?

  35. Hi Andrei, Sorry to hear that. I would suggest once you do your research and tap into @Luke K P's experience, book a test drive to get a real feel of the car as this is only thing that will either keep you going in the same direction or look for something else. I personally think that there is no vehicle like it in today's market. it is a Jeep 392 and a Toyota Tacoma TRD Pro, combined in one truck (Coincidentally the only two vehicles In my wishlist). Best of luck!

  36. Deserts in Dubai have become very unpredictable. Normally we revisit tracks once every few weeks, and between drives they those areas become unable to be driven. The vegetation growth is mind blowing. Areas that were prestine deserts look like gardens now. I started to do Faqa’a from the east from Abu Dubai. I wanted to go besides the solar park area this week, but alas, looks like the Phase VI has started and the area has also become super bushy. So had to drive back to the useual track. a very happy belated birthday @Imran Asghar. I hope you had some fun. This will be the summary of the drive: Glad we saw the couple of water bodies. Later in the evening at car wash they took an hour cleaning all the dirt.

  37. Thanks everyone for a excellent drive. @JeromeFJgreat leading taking us into some exciting and new (for me) terrain. Really spectacular scenery. The FB+ debutantes @Aserand @Shaun J drove supremely well, and were very handy with the shovels digging my car or from the full body cresting on the ridge! I claimed first stuck of the drive 😎 Both myself and @Robk got to enjoy the full pleasure of long wheel base vehicles in technical dunes with some shovels and ropes. The big bowls were great fun, as were the back and forth crossing of ridges towards the end of the drive. Was great to see big combo of FJs, jeeps, the big patrol, and the retro livery LC71 dominating everything that Jerome put in our parh Here's a couple of captures videos of the convoy... I'll get some more of my camera tonight I hope. Cheers and see you all in the sand again soon. https://photos.app.goo.gl/gTS4rsRDK2pW3i1h7 Side sloping https://photos.app.goo.gl/nRtnjCE9gZAvxry5A Briefing sky time-lapse https://photos.app.goo.gl/6VsNe46o3uZczysdA Team loops https://photos.app.goo.gl/kJqXDdDDf7BrjSQAA Ridge crossing with refusal

  40. Dear Desert Drivers, Thank you you joining the drive today. As expected, the desert was still showing the effect of the rains of last week. Starting with the meeting point, still totally flooded. Once everyone reached, we drove on the tarmac a few km and entered a bit further. The sand was generally still very compact, offering a good grip beneficial for the high climbs. The crossings were also generally facilitated, but the edges were sharper than usual, requiring a perfect accuracy for the driving line. A few other traps in the form of steeper pockets than usual, salt crust remaining from evaporated water ponds in the flat areas, water or sludge on the flat sabkhas. All this did not prevent us to enjoy fully the area. We had our share of high climbs, steep descents, ridge riding and crossing and beautiful desert views. The first portion with bigger dunes, more thrills and sensations, the second portion more technical with totally virgin dunes. Very well driven all of you. @Shaun J, @Aser excellent focus and control for your first FB+, @Julien Recan @Deepak Eswar you had one crossing a bit hazardous, but well done for the rest, @Luke K P @msa @Robk @Frans M, excellent control in both portions. Special thanks to @Luke K P as Second Lead, and @Deepak Eswar for the Sweep, both of you very reliable today. Enjoy the rest of the weekend and see you soon!

  41. Nice helper feature @Gaurav., but nothing beats just practising doing it manually πŸ˜…πŸ‘ Some offroad modes don't lock the rear diff in 4H. Sand mode does. But then rear diff can be configured 3 ways in offroad mode in 4H, Locked at all speeds. Locked at < 40, then automatically unlock above 40kph, relock when speed drops. Unlocked at all speeds. And then save that as the new default for your custom off road mode.

  42. i believe from looking at the other comments in the forums the 10 second long press will fully kill the ESC if you are in sand mode with rear locker on. In BAJA mode the 'active rollover prevention' mode will stay on even with ESC long press and mess with the brakes if it thinks you are over a certain angle. Can be prevented with by removing the ABS relay or aftermarket kill switch... in any case i have not noticed it kicking in unless im in baja mode or forgot to switch from 'normal'.

  43. price is about right. of course can negotiate on price and insurance etc to get a better deal. The 392 and F-150 raptor R move into much higher price brackets very quickly, with the added extra power. However at the weight/price of rubicon / ram / tacoma i think the stats tend to lean in favour of the ranger (rubicon of course kills it in angle of approach but i think ranger is good enough for the dune bashing vs rock crawling needs here) Nice that its also the same model (Thailand built) that has been extensively desert proven in last 2 years in Aus and South Africa. Its now a known quantity in the desert with the quirks well known. ( not having full under body armour... if u look at my insta you can see the full body plates remedy for this ). Lots of aftermarket build parts from offroad shops in au/za/th and a few garages here have worked on quite a few of the uae delivered models now to know what needs to be done. prewired aux switches with cable butts in rear under the tray and engine bay makes installing compressors / lights simple enough to do at home. fyi comes standard here with nice electric rolling tonneau cover.. which def does the job for me. apart from bash plate some some pretty lights im staying stock this time around

  44. Hey mate. Just recently changed from pajero to ranger raptor. It's definately ready to go out of the box. Rated very good on the @Gauravscale of power to weight for desert play. Great clearance. Suspension is unbelievable when off road (and on) My only issues at the moment are trying to find most comfortable driving mode in sand. I find that the baja mode holds the throttle a bit longer than you would expect when you take the foot off (to keep the turbos spooled).... Might just take more getting used to. Rear end can feel a little loose as there is very little weight over the rear wheels. So I've noticed a bit of changes to my driving style. Using Baja suspension mode, 4H, sand mode with full time rear diff lock enaganed, ESC turned off seems to be the sweet spot for me. 'Off-road cruise' set to 2kph with front and rear diff lock engaged will automatically crawl you out of any refusals allowing you to focusing on just getting wheel angles right and turning left right to clear sand. Let the truck handle the blip blip. Spent a weekend just making stucks to play recovery and was greatly impressed. Only upgrades required is a thicker bash plate to cover the engine and trans as the factory one is like 2.5mm aluminium. Price point to power and features I think U get a very compelling package compared to the offerings in other truck brands and the jeeps. let me know if you want more info or anything cheers mate.

  45. While offroading, we cross dunes by using different methods, based on how the dune is formed and what the drive level is. Once you have spent some time in the desert, you will slowly start to pay more attention to the dune formations and how we cross them. Once you reach Intermediate and Advance level, you'll need to start learning how to read these dunes in order to navigate and create your planned routes in the desert. As a rule of thumb, the prevailing wind in UAE is blowing from a North-Western direction to South-East direction from 10AM onwards. At night and in early morning it will be reversed and blow from the South-East to North-West. This is something you should remember and you will notice when you zoom into certain areas with your navigation app (Google Maps, Gaia, MotionX, Mytrails,...) you will notice that the wind from that side has caused the dunes to take on their shape. This is a general rule and will not always apply, as you will see that in certain areas where wind is coming from different directions, you will see for example "star" dunes appearing. There are different types of dunes which are separately described below. As you can see in below picture, a dune is formed when the prevailing wind blows on a mound of sand, where the grain will move into the wind direction and create a ridge. The sand which falls on the other side of the ridge, creates a slipface, and this sand is not compacted by the wind. This is the main reason why we generally drive on the prevailing wind side or the convex side of the dunes on the Newbie level. "A dune is a curiously dynamic creature," wrote Farouk El-Baz in National Geographic. β€œOnce formed, a dune can grow. It can change shape and move with the wind. It can even breed new dunes. Some of these offspring may be carried on the back of the mother dune. Others are born and race downwind, outpacing their parents. [Source: Farouk El-Baz, National Geographic, February 1982] The shape of dunes is affected by things like the strength, direction and consistency of the winds; the consistency and amount of sand; the hardness of the terrain and the amount of vegetation. Below we will describe the most common dunes found in the UAE. Different Dunes Crescent or Barchan Dune This is the most common dune. It forms the shape of a crescent moon when the wind blows from one direction. We generally use the words concave and convex to describe both sides of the dune: * Concave is a shape that curves inwards. * Convex is a shape that curves outwards. Crescent-shaped mounds generally are wider than long. On the concave side you will have the slipface. These dunes form under winds that blow from one direction, and they also are known as barchans. Parabolic Dune A parabolic dune is similar in shape to a barchan, but it is just the opposite. The tips of this dune point into the wind, and its main body migrates with the wind, forming a depression between the tips. Because of this formation, parabolic dunes are also known as blowout dunes. These dunes often occur when vegetation stabilizes sediments and a U-shaped blowout forms between clumps of plants. Example of Parabolic dunes near Faya: https://goo.gl/maps/ob8xu3y8VJJvF6hk8 Longitudinal or "Seif" Dunes They are also often referred to to as "sand ridges" or "seifs". Their length can range from a few meters to many kilometers and their height from a couple meters high to a couple hundred meters high. Wind pushes the sand and forms ridges parallel to the prevailing wind direction with slip faces either side of the crest. Linear dunes are straight or slightly sinuous sand ridges typically much longer than they are wide. They may be more than 160 kilometers long. Linear dunes may occur as isolated ridges, but they generally form sets of parallel ridges separated by miles of sand, gravel, or rocky interdune corridors. Some linear dunes merge to form Y-shaped compound dunes. Many form in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement. Barchanoid Dunes These ridges are similar to Barchan dunes. They are connected in long crescentic waves as the sand supply is much greater than that which forms a Barchan Dune. Star Dunes These dunes are formed when there are several prevailing wind directions - there is a complex wind regime. Typically there are three or more slip faces, whilst the dunes do not migrate they grow in height. Star dunes are radially-symmetrical, spyramidal sand mounds with slipfaces on three or more arms that radiate from the high center of the mound. They are created when the winds blow equally from every direction, causing the sand dune to grow many extensions and resemble a star. They are rare and are fairly stable and remain in the same place. Some are landmarks with names. Example of a Star dune: https://goo.gl/maps/jRnYghQc8ACzVz6T7 With this knowledge, the next time you step into the desert, you can start looking at the different dune formations, and this will give you lots of knowledge that you'll be able to apply in the future when leading and navigating off-road drives.
