All right guys, as of recently, I've noticed my rear right coil over is lower than the opposite side. So I took my rim off, and checked everything. Everything seemed to be okay, but I raised it up a little. I put the car back down, and guess what? It's the same height.

My front left is starting to do this also. I checked it (I got backed into it recently) and everything seems to be good there also.

None of my struts are leaking, and it seems to have rebound.

What are the chances the springs themselves have gone bad?

They are a set of TEIN Basics for JZA80, I've had them for about five years or so now.

 

How much did you raise it up by?

And yes, (cheaper) springs do wear out. Tein springs are no exception.

 

I raised it a good bit, I had five threads, (from the bottom), now I've got about ten or eleven.

I think it's spring fatigue also.
