I have a 90 AWD with a 4bolt rear end that I've had on for about 5,000 miles. Well my center diff blew and I ended up getting it welded and having my tranny rebuilt. Now when I drive the car all for wheels seem to be semi-locking up and rotating at a different rate. I ended up disconnecting my driveshaft and transfer case and I'm running FWD for now. The rear diff seems to run fine with the half shafts still attatched. I don't hear any noises, but I sometimes feel a slight vibration coming from the rear upon initial take off. I know the transfer case isn't seized because I opened it up and everything was fine. I'm pretty sure its the rear diff.
Now after thinking about it I realized that the label number on my rear diff says, "J1H" with Viscous LSD above it. My original 3bolt had an LSD btw. I know that there are other 4bolts with the label "B1H" or "B1G". Is "J1H" for automatic? That would explain why my center diff blew and why my car still struggles to move. I made sure when I bought the rear diff from the guy it was from a manual not an automatic. Can anyone tell me if my 4bolt is for an auto AWD? Thanks for the help!
