Hey guys, about a week ago I was coming home in a snow storm and the car got a bit sideways and hit a curb with the driver rear tire. Now it makes a slight wheel bearing noise, but what im concerned about is the back end feels floaty. at high speed if i lightly tap the wheel it body rolls on way and pulls the other a little bit, or if i hit a bump sometimes it wants to pull a little. At low speeds when i swerve back and forth the back end feels like theres a pivot point in the middle of the "rear end" and also as if it is sliding sideways a few inches on the "rear end". I had the car on a jack and i didnt see anything bent or broke, i had a friend watch out the door while i swerved and he said he couldnt see anything out of the ordinary. Please, if anybody could point me in the right direction i would greatly appreciate it. Thanks!

Trailing arm bushings shot? The more worn they get, the more slop you'll notice in the rear.

I just checked it out again in a little more detail, I think i just @!#$ the wheel bearing up pretty bad. Let's hope it's that simple.

if your still having issues after changing the bearing; you might want to get the alignment checked. If the rear toe was changed you will get the symptoms you described. If its worse on wet or slippery road condtions the rear toe/ thrust angle issues are likely....get a 4 wheel alignment to confirm.

Our rears aren't really adjustable (in a sense)...we have a solid trailing arm, not IRS. The most you can do to adjust is shim the rears if needed, but it's barely enough wiggle room to make the kind of difference the OP is talking about. Check the wheel bearing, then move onto bushings.

I not suggesting any adjustment is available for the rear end. The rear alignment angles (toe, camber) could be out due to the impact. the only way to tell is to perform an alignment check. The prealignment inspection will check all suspension components. The rear axles bend easy on these cars. I've seen a few as I do all the alignment analysis for the body shop at the gm dealer I work for.

GM's term fot the rear suspension set-up for this car is; a twist axle
