Ok guy so my 95 LT Trans AM is doing something interesting. It has slightly wider tires in the back but i had gotten used to that by now. Last week i changed the rear end cuz mine was shot. Now the car on the free way like when your driving straight on smooth roads seems to like wanna move on its own. Holding the wheel as steady as i can the car sways from left to right pretty bad. If i hit a bump it almost feels like im gonna lose the rear and the car jerks violently. Its really bad? Any ideas?

 

What kind of rear end did you get? Are you sure everything is installed correctly, nothing over tightened or too loose?

 

yeah its in there fine its just a replacement stock posi rear

 

all the bushings good in the rear, sway bar and stuff? I have had a vehicle do that before and the bushings were shot in some of the susp in the back. Could hardly tell by just looking, but if you wiggled the bar it had alot of play.

 

what bushings?

 

that might be the problem...lol

 

lol if i knew what it was i wouldnt be asking you guys

 

Did the panhard bar (the horizontal link) get reattached? It's the main link that holds the rear straight and centered in the chassis. Check it's bolts, and all the others for that matter, sounds like somethings loose.

wow ok so i just checked an the panhard bar bolt is in but the not isnt on all the way and the bolt slides back and forth so its not tight at all ... could that be it

 

Yup.

 

Lol there you go even a little bit of play in susp can cause a huge problem.
