I was wondering if anyone here had a similar problem. My rear end sorta “shifts” to the right every time I hit a bump with the right rear wheel. I had a look at the bushings and they look fine. Any ideas?

Check the subframe bushings… they are probably gone. Common S13 issue.

you may have excessive negative camber or shitty tires, ball joints, busted rear struts / dampers…

i’d say ball joints.

i’ve had ripped subframe bushings. that causes more of a knock due to up-down motion rather than side to side play.
