Help - MM 540 wobbling !!!
Somebody needs to help us in this.
I was getting this wobbling feeling from my MM540. This is more when you are at the wheel or while sitting on the rear seats.
We tried out remedies.
We changed the rear housing from 2 wheel to 4 wheel drive, thus moving the rear housing from left to right side. Our idea was that since the gearbox was on the right side, the diagonal transmition of power was the culprit. But this hasnt changed anything, the wobbling continues as it is.
And one more thing we have seen is the extra wear and tear on the inside of the right rear tyre, which we think is because of the wobbling.
What would be the reason for this wobbling?

What propeller are you using, is it a stock unit? and hope you have ruled out other obvious factors like wheels and steering before this?

We got the engine with the gear box along with it which had the joint(propeller). We gave the propeller shaft to the leth to join it. Would an improper joining lead to this?
And also will the misfit propeller shaft lead to rear wheel wearing out ?
Thanks for the time mate, really appreciate it.
And also we have got the steering and tyres checked, there are no problem with it.

Since the wobbling is from the rear, it is most likely either of the following:
1) Bad wheel bearings.
2) Bent Rim
3) Warped rear axles.
4) Bad Tires.
5) Hubs not installed correctly.
6) Rear diff not aligned correctly when converting to 4x4 rear axles.
Miss-aligned prop shaft won't cause wobbling of the tyres, but will cause other issues.

I agree to what 4x4 addict says, also hope the LH and RH side tire size and pressures are correct.

If there is wobble, jumping, lurching effect in 4WD.
Also Check if all 4 Tyres are the Same(Diameter).
Check the Front and Rear Differential Ratios.
If there is severe body vibration in 2WD/4WD, check the T-Case Mount & Bolt.
If tightened too much there will be vibration, same if it is loose.
And as Mr.Behram Dhabar, strongly suggest, Get a SPIKE ARRESTOR.
If the steering wobbles/wheel wobble that is another issue.
For the Rear Differential
1) Check Wheels (Balancing/Rims)
2) Check Wheel Bearing
3) Axle Key/Check Nut & Cotter Pin (2 Piece SFRA)
4) Check Body Beds
5) Spring U Clamps.
6) Shock Absorbers

We just found out that the cross member on the chasis has come off from one side. So we are trying to get this fixed and see if the wobbling stops.
Stay tuned till then, if it doesnt get solved then would need more help.

Re: Help - MM 540 wobbling !!!
My recent finding .( Arka's point 6 on post 9 confirmed )
shock absorbers on axles ( NOT on steering linkage ) , do have a say on wheel wobble / death wobble / king pin Wobble
I would not have believed it but a change from a totally faulty pair to new ones made a 'very' notable difference .
I could observe this as I traveled the same track with the old & new pair numerous times .
On a lighter note , came across a novice LR owner complaining about wobble on turns & tight steering ; reason found ? he was on 4 wd engaged all the time
