Hey I'm new here and looking for some friendly advice from someone who knows more than I! I have a 93 Legacy Auto 2.2 AWD that I bought for a nice price but it had AWD issues meaning the clutch packet was shot. I drove it for 20k like this with the FWD fuse in. So i bought a used trans from a buddy thinking I would slap her in when this trans ************s the bed. It just started making horrible shuddering noises around corners and slipping, so I swapped it out for the new used one and it all seemed to go pretty smooth, no check engine light, shifts smoothly. but seems to have a binding feeling in the rear around corners, something is wrong! could it be my rear Diff? rear CV? Any advice would be appreciated, I need the Awd to go skiing! Cheers, Josh
