please can any one help me i am very wet behind the ears with this new jeep of mine
on turning at slow speed i get a judder like the rear wheels are turning at differnet speeds locking up or something in reverse and forward in either 4 all time or 4 lo (at least it seems to be the rear wheels makes a nasty grinding anoise too )
i now own a 4.7v8 grand cherokee overland year 2002
and it has developed this problem
i have been told it could be the transfer case or the rear diff but both being ewxpensive to do dont want to get it wrong is there any way of checking either or is there a common problem with one of them
can any one help me
ps what model is mine is it wj ??
thanks
