So I have a very annoying, and persistent problem. One year ago I busted my stock 10 bolt. so i "upgraded" to a Moser 9''... Ever since then I have had more problems and solutions then I can explain. Anyways, when your going 45ish the car jerks you back and forth like something is grabbing the back of the car and letting go a few times.(Yea bad analogy) The other problem is the 60ft is constantly getting worse(1.5s-1.6s) The car also makes a popping noise when ever you stop when the car is first started up. Theres also alote of vibration in the car which has gotten WAY better since I installed a new DS, body mounted Torque arm and, new Lower control arms. ANY advice, opinions, questions or ideas will be greatly appreciated.

 

I would drain the differential and see if the fluid has metal in it, could be your differential.
