I've got server inner tire wear on the rear of a 93 Legacy wagon. We did swap the complete drive line a and suspension from a 92 wagon, but as far as I know 90-94 are the same.

 

No camber adjustmets, I believe? What's the fix? Thanks

you can move things a little bit when loosening the strut bolts.....

 

They do make aftermarket camber bolts you can add which will give you a little adjustability.

Thanks for the info. I'm going to loosen both sides and pull them together with a strap and tighten things up.
