The spacer im talking about is the long spacer on the AE part. I haven't taken apart the case yet. I need to check is the bearings slide all the way on too. I'm sure it's not the shaft. It's gota be something I'm doing.
At the last regional my car was making the worst EVER diff screeching and grinding and barking noises. Day before it was fine with a slip only here and there. Every time my car wet down the straight I couldn't help laughing. It was as if my car was telling me "Don't pull the throttle" but I gave it all. I couldn't clear any jumps either, but I still made the B. Goes to show that going slow is fast in the right conditions. And I need to have a spare diff.
