Been lurking for years, and was always able to find what I needed without having to ask. But I'm officially stumped and need some help.

As I drive down the freeway, the car will wobble - not vibrate or shake - but kind of a slow wobble - from side to side if I hit a little depression in the road. It almost feels as if the body is rocking from side to side on the frame of the car.

So far, this is what I've changed:
- All 4 strut assemblies
- both front control arms
- all four sway bar bushings
- all four stabilizer bar links
- engine and transmission mounts
- both front lower ball joints
- drivers side CV axle

I did notice that the passenger side rear wheel has a small amount of movement when I rock it back and forth at the 3 and 9 positions when off the ground. Any help would be greatly appreciated. Thanks!

 

The max in/out wheel rear bearing play is 0.002 inch which is not a lot.

Check the rear suspension arm and strut rod bushings for excess play. They can wear out and cause drivability issues.

Check for a bent rim and or tire having a bulge from ply separation.
