Hey Black G Wagon,
How do you know it's the diff ????
What sort of vibration ????
Normally when the diff is going you might see
alot of ware on 1 tyre or on tight turning circles
it "clicks" or judders .........
well when i plant it in first gear the car pulls hard, change to second gear and pulls on with vibration from the rear, almost as if the rear is losing traction. vibration not there in thrid, fourth or fifth. ?????????
Hmmmm!!! that's a strange one allright,
Sorry haven't come across that before ,
hopefully one of the lasd will be able to point
ya in the right direction.
