Ok so I recently purchased an 05 Evo and the center differential already went out on me. I don't have any kind of warranty on it so i have to fix it out of my own pocket. The dealership wants $4,300 for parts and labor!

. I looked and looked then looked some more and failed to find any kind of center differential online. So if anyone knows where i can find one for somewhat cheap please let me know. Another question does anybody know if this is a common problem with the 05 Evo's or if it's just my car. Any advice will help. Thanx!
