If Part time uses 4x4 all the time, surely there are no disadvantages to doing that,

@Josh S ah Jeep and its marketing terms compounded by seasoned individuals who advise without explaining technicalities. You have the Rock-Trac Transfer Case with 5 positions and the confusion is 4WD Hi Auto vs 4WD Hi Part Time. The Part Time moniker is Jeep's tongue-in-cheek way of saying "use this part of the time". Why? 4WD High Auto for non-Jeeps is the same like driving the default Patrol and Land Cruiser: it means turn all 4-wheels at same time, otherwise known by non-Jeeps as Full-Time 4WD. There are no 2WD in Patrol and Land Cruiser so we just casually wait and watch Instagram everytime a Jeeper says "enganging 2WD" 😂  4WD High Part-Time is the same in non-Jeeps as Turn-All-4-Wheels + Lock the Center Diff. This splits the torque front diff 50% and rear diff 50% and all 4 wheels move at the same rotational speed. Rally drivers use 4WD + Center Diff Lock when in long straight track as it gives more traction to push the car forward. They turn off when making sharp turns or many zig-zag turns. 

You just triggered something that was buried in my memory. After my rollover, I noticed my Center Diff Lock light was on, and this was a mistake. The theory of turning wheels and the invention of differential is to allow front wheels to turn at slower speed than rear wheels, thus making a smooth turn. When you lock the Center Diff, the front wheels turn at the same speed as rear, so when you turn with Center Diff locked you will be DRIFTING. Now imagine me turning 90° with diff lock on to steer down the car during a high-speed side-sloping at 8psi... yeah I don't think you'd do that as I'm a proof of what happens when you do that 😂

People who drive with Center Diff Lock on don't realize this or downplay this theory because their current sand is so soft that the stress of turning wheels at the same speed get "burned" by the sand / cool drifting. But ONCE they got the hard sand and turn 90°, it's the same as turning with Center Diff locked on asphalt. You can do this at home: turn 4WD + Part Time in your parking area and try turning 90° left-right. That effect will be the same when your sand changes from soft to hard sand.

To understand more about Differential, I implore you to read my article below, young padawan 😅

I reached meeting point, Gok sleeping in parking bay little before the meeting, let's all catch up there.

I'm roaming around to find an entry through the fence, as expected.

Exploration already started it seems 😅 Please save petrol, we can always go back to Milky Way for a drive towards Hameem 😂

@Looper apologies in advance I'll be driving LC tomorrow, will try to be gentle on throttle so it doesn't churn up the sand for you 😅  @Gaurav sorry forgot to update my sig, ol Jeep air-conditioning died and i hate driving it during humid + summer 😂

I am planning on getting fuel at the Al-haffar ADNOC (24hr)  and taking a 20lt Jerry can. (Number 1)

there is the closer ADNOC at AL-RAZEEN (number 2) but it is not 24hr, opens at 6am I think.

@Stumpy Paj Al Haffar 676 is across the road of Al Faya 891 (the one I mentioned earlier), you'd use Al Haffar 676 when coming from Sweihan towards Abu Dhabi. If you're gonna use Al Razeen to Al Quaa road to the meeting point, I suggest follow the Abu Dhabi Boys route below 😁

@Zed this one is gud for us, coming from Abu Dhabi city and is open 24/7

Yes WhatsApp me before leaving, we can sync up at Adnoc, then drive Fast 'N' Furious style and use adrenaline to fight off sleepiness in the dark long straight boring road towards Al-Quaa, and probably have wasted enough fuel, needing transfer from jerry-can into our tank during deflating 😂

@Gaurav Bhai - I see 100 kms from Gas Station to Meeting point - is this correct ? ( May be time to carry Jerry cans ? 

There's another ADNOC Gas Station 80km from meeting point so you can save 20km range 😅  After filling there you exit first right into the farm road and keep on pushing till you see the Big Razeen Roundabout.

Looking cool whilst wearing them is a bonus but not a requirement 😁

@PETELCZYC PAJERO - luke The ARB orange ones are good especially if you get them during the offers seasons (Adihex, Black Friday, End of Year, Ramadan) and available locally by visiting shops so you can try them.

But Black is Cooler, I got the Warn Winch Gloves below 😊

Just search on Amazon for "WARN Winching Gloves"

Here it is... Xterra 6 cylinder, off road version, manual transmission. 

@Sreenath G that's a powerful combo: the XTerra uses the same VQ40 engine as Y62 V6 + the 6-speed manual has 1st Gear Ratio of 4.37, higher than Land Cruiser and Rubicon's 4.1 first gear, so means on 4H 1st Gear you already have lots of torque to move the wheels (good for climbing tall dunes).

Looking forward to see this beast on the sand when we're in the same convoy 👍

Does anyone know of any car workshop in Abu Dhabi that can provide car styling, body and frame modification ? 

Basically, I'm thinking of taking a 4x4 donor vehicle chassis and modifying it into my project concept vehicle

Any help would be greatly appreciated !

@Dare_to_Dream One thing couple of members including me have noticed is: Do Not Trust Garage Instagram Accounts 😂 cc @Wade Pat2 @Chris Wing  . Use the 3 methods below:

1. Use Google Maps, type Musaffah so it centers from there. Then search nearby for "Car Modification", it should bring some decent results.

2. One-by-one, read the reviews (you can even translate the Arabic reviews sometimes they give more valuable insights).

3. Once you have narrowed it down to Top 5, find their Instagram accounts and check their Project Photos. Those that are closer to what you want to build with your concept car will make it easy during building (i.e. you can tell them "I want modification just like the one you did here on Insta.."). Yes I know I've said not to trust their Insta accounts, so eventually you have to use your "Spider-Sense" to gauge whether a workshop is full of marketing people instead of mechanics, welders, denters, electricians 😁

Occam's Razor Principle: sometimes the simplest could be the answer 😁 I'm putting the "How to test your Horn Device is working using Normal Car Battery" link below (skip to minute 1:39) so others next time can do this test first before checking the yellow clock spring in steering wheel 🙂

For the ones that did the FB+ drive last week with me, it will be a similar route but i will try to up the throttle one notch further if all goes well. @Jona@Jaro Tuzinsky@Mus_hus78@Zed you guys got the first flavor last week so you'll be prepared for that extra push  

Looks like it's down to 10 people + managers, so it will be a Replay 🎥 of last week BUT with Fast-Forward Button ⏩ *zoom zoom 🏎️🏎️ 👍

Apologies for the confusion this morning, the drive is coming Sunday and not tomorrow  

Since it's Intermediate, am sure the guys who don't read the forums before driving are gonna end up driving into the sand anyways 😂

It's not an issue, it's just specification let say. Rubicon transfer case ratio is 4:1, when Sport, Sahara and Sand Runner/Mojave is 2.71:1 At same driving conditions Rubicon generally much slower, which is huge advange in rock crawling and disadvantage in dunes climbing. Rubicon positioning as an high loaded option, but all that quite useless in the desert. 

@Pavel Pashkovskiy @Mark B  First of all this only matters if you're driving in 4LO, but as a part-time Jeeper, I can confirm to this. I always drive my Cherokee in 4LO + 5th Gear, and 4LO + 3rd gear when towing a Patrol 😅 ( @Frederic can confirm this ).

The 4:1 is LOW/4LO Gear Ratio, the High/4H is always 1:1, that is why 4L is also referred to as Reduction Gear, it reduces to crawling speed. Link to my old Gear Ratio Calculation post below , but I found another photo that explains better (also below). There are other Ratios that affect calculation: Ring & Pinion (sometimes shorthanded as just Axle Ratio) + Transmission Ratio itself (which is different for each Gear Shift) + Transfer Case Ratio

Assuming both Rubicon and non-Rubicon uses Chrysler's TorqueFlite 850RE 8-speed, which is licensed from ZF 8HP50 (used in BMW 5, 7, X3), here is the calculation for both when driving in 4LO 6th Gear (6th gear is where transmission ratio=1.0) for all cars:

Rubicon w/ 4.88 Axles (newer ones):
 - 4L 6th gear = 4.88 x 1.0 x 4.0 = 19.52 final 4LO spinning ratio (bigger means more crawling - less speed).

Rubicon w/ 3.73 Axles (older ones):
 - 4L 6th gear = 3.73 x 1.0 x 4.0 = 14.92 final 4LO spinning ratio.

Sport/Shara/SandRun/Mojave 3.73 Axle + 2.71 4LO:
 - 4L 6th Gear = 3.73 x 1.0 x 2.71 = 10.11 final 4LO spinning ratio.

There is an easy solution to this for Rubicon, just switch to 4LO + 8th Gear:
 - 4L 8th Gear Rubicon = 4.88 x 0.64 (8th gear ratio) x 4.0 = 12.5 final 4LO spinning ratio (close to Sahara's 10.11)

OR, Rubicon can drive in 4High with 3rd Gear:
 - 4High 3rd Gear Rubicon = 4.88 x 2.10 (3rd gear ratio) x 1.0 (4Hi)  = 10.25 (very close to Sahara's 10:11 on 4L 6th).

Assuming huge price differences between Rubicon and non-Rubicon (I just buy old Jeeps so not sure about new prices now), my recommendation is: if it's ONLY for Sand, then Sport & Sahara as cheaper options are better. You will only drive in 4Lo: most sensors are turned off already + when you're stuck or refusal you're already in 4Lo 😁

BUT if you want to do some rock-crawling and also sand-bashing, then Rubicon is a better choice. Those high 4LO spinning ratio / bigger crawling are useful for crawling uphill and braking downhill at steady low-speeds.

I use my horn quite regularly during daily driving...(its amazing how many people need my horn assistance when navigating round-a-bouts in abu dhabi 🤪)

today i just get nothing. no noises.

Checked fuses 12&13 in engine bay and they are fine...

is there anything else *simple* i should check before taking it to the mechanics to have a look?

i had the same issue after the rollover, below are the steps my electrician did:

1. Use a meter to probe the relays if they are good instead of unplug-and-replug. They were good.

2. Open the steering wheel cos the horn and cruise control wirings go through the Yellow Spiral Clock Spring thingy. The yellow clockspring was ok.

3. Finally he used the Electrical Wiring Diagrams to probe the wirings, and found one wire needed soldering.

Good luck with yours 👌🏻

i was thinking about doing a drive from Al Hayer (Dubai-Al ain Road, all the way to the Telal Resort from where we started. That would takes us through both Sweihan and Remah area. What do you guys think  ? Will start planning for it as soon as the weather cools down a bit.

That's about 50km straight line @Frederic , sounds like a good half-day plan, but only when the weather improves... can't imagine shoveling at 11.30am at 40 Cels 😅

Hi @Simon D if we work backwards from the problem, then you may derive your own conclusion here:

So the problem starts with engines equipped with EGR (Exhaust Gas Recirculation), where some of the exhaust gas containing Nitro Oxide are being re-routed back to the cylinders to be burned off again. But at the same time, oil mist from the crankcase also enters the manifold. The combination of oil mist + exhaust from EGR = soot / carbon deposits, which you saw when you open your manifold (for others refer to photo ref #1 below).

So doesn't matter Diesel vs Gasoline, if you have EGR, you'll soon see soot 😁but because Diesel produces Nitro Oxide more than gasoline, you'll see EGR being enforced for Diesels in environmentally-friendly countries.

Solutions to the Soot:

1. Yield to the Manufacturer. This is when everyone says "if Mitsubishi engineers are so smart, why they let this happen?". So EGR is a Law-thingy, and they cannot sell in Europe, America if they don't comply. If you accept this solution, then we can just chin-up and pay when the lazy mechanics say "oh, this soot is too much, we cannot clean it, let's buy a new intake manifold" or "the soot came back within months, really? Then we need to replace your EGR Valve, it may be malfunctioning!"

2. Delete EGR Valve + Blanking Plate:  this removes the valve that close/open to allow gases to re-enter the manifold and block the hole for EGR with a plate. Note that modern engines open/close valve electronically and have sensors, so assume the Computer does some assumptions and calculations based on EGR. So if you delete EGR, it may throw Check Engine Light. Is it safe? EGR is turned off during idle, otherwise it will cause rough idle, so technically with EGR off, engines can still run fine. Deleting EGR is like Deleting Catalytic Converter, it will throw CEL, it's bad for the environment, but car will still run fine.

3. Prevent Oil Mist from re-entering to meet with EGR: this is Catch-Can. But if you do #2, which is more effective, you don't have to do this Catch-Can thingy. If you love the environment and don't mind emptying Catch-Can every month, then this is the solution you'll choose.... until you find out that your Catch Can is still producing soot every few months 😂

Good luck with your choice, and update us after few months of implementing it 🙂

I would like some advice on the benefits of having a tank connected to the compressor.

• is it faster?

@Alphin Aloor no it's not faster. The tank is to run "Air-Tools". This is why ARB gave an air-gun to blow compressed air and clean your engine bay or car interior or inflate air-mattresses when camping. The best is if you need to change tires, you can use Air Impact Wrench to open your tire lugs instead of manual-wrenching 5-6 bolts 😊.

The theory why an Air Tool (airgun, air-wrench, air-hammer) needs a tank >> "A tank dampens pulsation, providing a steady flow of compressed air at constant pressure. Uniform airflow makes it easier to work and reduces wear on your machine"

Thanks Doc @M.Seidam , the last 1 hour was exhilirating! 👍🏻  Got to test my new skid plate surfing dunes & ripping ridges 😁 There were some sticky situations, but with ideas generation and teamwork we overcame all these obstacles and glad everyone exited safely. @Rizwanm2 was great 2nd lead, amazing that he continued & persevered after the pop-out, managing to catch up the Marshall with just 15psi 👍🏻 @Senthil Kumar great meeting you bro and good driving, hope you get the front hook fixed.

confirmed @Varun Mehndiratta, just saw there's still space in this drive 😁
