Pajero 3.8 LWB 2020 - Steering Vibration

[Raj K]

Hello Pajero Owners,

Need advices from the Pajero owners / experts.

I have a 3.8 LWB Pajero 2020 model.  I am feeling vibrations after 80km/h even small undulations of the road.  I have done the following modifications.

1. Done major service at 120k kms.

2. Changed Engine and Gear Mounts

3. Changed Brake rotors and pads

4. Changed to Yokohama Geolander G15 with 18" oem rim

5. Installed Dobinsons MRR Suspension and Dobinsons Coil springs with 2" Lift

6. Added H&R Spacers

I checked Tie Rods, Sway Bar bush, UCA, LCA which one garage said need to be changed but the other garage said everything is fine.

Any suggestions to understand or diagnose further for the cause of steering vibration.

Quick question how many off road drives have you done on the G015 tires?

Could you describe the type of steering vibration you are encountering?

1. Left and right wiggling of the wheel while on highway?

2. general vibration of the vehicle itself?

 

1) If the steering is wiggling left and right this is 90% of the time related to wheels and tires. Either one of the rims has a slight dent, or one of the tires has an unbalance. If you ever faced a popout then of course there could be sand in the tire as well.

2) if there is a general vibration of the vehicle (usually noticeable when are looking in the rearview mirrow) this could be more related to the driveshaft. I personally encountered this and eventually had to get the driveshaft rebalanced.

Hi Andrew, I have done 6 drives with the G015 tyres.

Hi Frederic,

It's the general steering vibration and not L&R wiggling.  I can mostly feel on my hand.

I've called in the help of AI  

 

See below:

A few clues that help diagnose it:

• Only steering wheel vibrates → usually front wheels/tires
• Whole car vibrates → rear wheels or driveline
• Vibration disappears above 120 → wheel balance very likely
• Changes when braking → rotors
• Changes when turning slightly left/right at speed → wheel bearing or tire issue

What I’d do first:

1. Check tire pressures.
2. Inspect tires for uneven wear or bulges.
3. Remove any mud/sand from wheels.
4. Do a road-force wheel balance if possible (better than normal balancing).
5. Then alignment check.

On the Pajero specifically, oversized tires or aggressive all-terrain tires can also create this exact sensation if they’re slightly out of balance.

If you want, I can also help you narrow it down with a few quick questions:

• Is the vibration speed-dependent only, or also RPM-dependent?
• Do you feel it in the seat/floor too?
