I have a frs 6spd transmission in my 97 imprezza and I'm having allot of rear end issues. First it's open from factoryou so I blew that up pretty quick. So I welded it. Then I broke the welds. So I brought it so a shop and they welded it professionally. Then I check under the car a few days later and there's a big ass hole in the diff cover. I just opened it up and it's not good. The carrier has split in half and all the crown gear bolts have loosened right off and the bolt are what smacked the cover. I've looked online and can't find and lsd's that are tough enough for under $1000. I'm wondering of the 2002-07 carriers will fit or even the whole diff but with my axles? I'm not sure how to go about this because if I just throw in another welded diff then it's just going to break again. What would you guys do?
