Okay, here is my problem to be fixed:
I bought a Jeep, 1986 CJ-7, with a SOA. From what I can tell, it was done wrong for the way it is set up. The driveshaft is a straight driveshaft (non-CV). The rear differential is pointing "up" at the tranny and the tranny is pointing straight out of the engine line (anywhere from 15-30 degrees mismatch, hard to tell). What is a better solution, have the spring perches rewelded to put the differential input and tranny output parallel, or to try a new driveshaft? I noticed that when I bought the Jeep, the U-joints were brand spanking new, and I asked the prior owner about that. He had just replaced them because they were chewed up, but did not know why. I think it was because of driveshaft wrap. What are your solutions here?
