Did an 89 iroc come with a posi rearend??
Also, Can anyone give me any ideas for my problem???... i can grab either one of my rear tires, pull them in and out (as i would be taking the wheel off) and there is enough play for it to move about an eight of an inch while the wheel is bolted down tightly?? When i pull the tire in and out it tends to make a slight hollow-sounding 'clunk' noise.

 

Probably.

That's normal.

What's your problem?

 

Thats normal?? Its normal to have play like that ?

 

Yes.

If you look at how it's put together, you'll see why.

 

About 21 years ago, I was almost flunked for tech before a race because the inspector didn't know about that. Fortunately, another inspector straightened him out.

After that, I always made sure I had the park brake on when I went through tech...
