I am driving.. Cruising speeds really. Ill be driving, say 45mph, and go over an uneven part of the road to find myself constantly battling the rear end swaying left to right. It all depends on which rear wheel hits a bump,pot hole,man hole cover, etc. in the road. Its annoying the crap out of me and cant think of anything else. Ive checked everything I could possibly check to my ability!!!

Any ideas?!

 

Need more info. What tires, what size wheels, are they oem or aftermarket, do you have any suspension set up like springs, coilovers etc...
Lots of reasons why this could be happening.

I always drive around pot holes, crap or bumps as much as I can.
Get me more info and I will try to help you as much as I can.

My car does not do that and I have springs installed with 20's.

 

Bump steer! Check your alignment. Mine was significantly more noticieable when I put the aftermarket wheels on.

 

OEM 18's with whatever the stock tire recommendations are.. Too cold to walk outside and look! As well as TEIN S.Techs with proper alignment.

It had done this before the lowering springs went on as well. Im just curious because its hard to dodge some bumps and such on busy roads here. Highways are easier to dodge since theres a shoulder or other open lanes.

 

I have a sedan. Pull up some of my old posts and you will find the answer for your problem. I was having the same exact issue.
