Rear Diff. Problems

[livestrong14]

Hey guys, my dad recently swapped out my stock 91' legacy turbo tranny for a jdm 92' liberty rs tranny. In doing so the rear diff binds. My car came with a 3.90 rear diff with viscuous limited slip. I have heard that I can just swap out my stock rear diff with a 4:11 to match the jdm tranny. I really want to have limited slip in my 4:11. Are there any USDM rear diffs that are limited slip and 4:11? any input really helps, thanks, devan

I had started a thread on building 4.11 LSD's but it pretty much died. once I have the time I will get an LSD and a 4.11 and try to make it work.

There's a guy on the SVX boards that builds LSD's. It would cost 250. But, there are some stock 4.11 LSD's...they were an option on 91 SS's.

the 91-92 SS's were the only usdm legacy turbo's to have a 3:90 LSD rear diff. they didn't have 4:11 at that time in the U.S.

The 2000+ 2.5RS and Legacy GT should have a 4.11 rear LSD that would work. There are also some Outback and Forester models, but they might be 4.44. Not sure about halfshafts or anything, but it's something to look into.

2000-2001 Impreza RS and Legacy GT have them in 4:11.

I should Know, I got one for Blackbart.

I picked up a couple more 4.11 LSD's if anyone is interested. Not cheap though, dscoobydoo knows what I pay!
