Ok, so I've got a 02 4x4 4.0 supercab FX4 with 128,000 miles on it. I have a problem. Mostly in reverse, but sometimes going forward particulaly when turning at low speed, just when you put your foot on the gas There is a slight vibration that feels like it's coming from the front end I had all the breaks checked/done and I've had all the bushing checked all is in good shape. However yesterday I noticed it while backing out of the garage and it sounded like a clunk and clicking noises coming from the rear end somewhere.

I have heard something about the wrong oil in the rear diff being the problem but that seems a little wierd, has anyone got any advise/expierence with this ? any help with would be great, Thanks.

I got my fiberglass done
