Dek,

You might get lucky and find it is some obscure, inexpensive, and easy to correct problem, but then again, it is much more likely that you won't! We don't get the easy or inexpensive solutions falling into our laps very often.

For the noise to be loud enough to be audible over your pipes and then loud enough to become an irritant, there are only two things that can do that. One is a bad carrier (or pinion) bearing, and the other is an improperly installed ring and pinion.

When you disassemble the rear end to remove the ring and pinion, it is a walk in the park to check the bearings. If they pass muster, then it is time for a new ring and pinion. It is really that simple.

All of the, it might be this, or it might be that BS, is a form of intellectual problem obfuscation. You attempt to convince yourself it is not as bad as you know it really is. Don't waste your time on the mental masturbation; fix the problem. After all, that was the original reason you embarked on this journey of pain and suffering.

This one has no easy or cheap way out other than do nothing and tolerate the noise until something breaks.
