Howdy all, Something to ponder.....
I have a harsh vibration under medium to hard acceleration at 55km/h (31MPH) and it comes in again at 100Km/h (62MPH). SO far we have tried this to no avail:
Remove rear prop shaft - problem stays
Remove front shaft - problem gone
Install brand new front shaft - no difference
Dissasemble and check centre diff - all just fine
Dissasemble front diff - all fine
Checked both CVs and front wheel bearings - all fine
Changed the wheels for some from another vehicle - no difference
Put the truck on a hoist and run it up to 55 - transfer case starts shaking - engage diff lock and the problem is almost gone.
The problem appears at the same speed in low or high range which to my mind rules out the gearbox. It must be from the transfer case on.
Where to next??
Any clues?? It is a '98 300Tdi with 80000km.
