Been having some problems with my differential (possibly). If it turns out that it needs to be replaced, I may be looking to source one hopefully from the WPB area. I know a bunch of people like to upgrade the E46 diff to a lower gear ratio, but I'm looking to keep the stock ratio, so hopefully I'll find someone with a spare stocker.

Thanks a bunch all! With any luck, I won't need to replace the diff, but trying to get a head start if I do.
