Excessive noise is the first clue. If it is an automatic, push down the park brake and move the selector from reverse to drive and back a couple of times. If if have a jerking and noisy transition, could be the rear axle. Nothing takes the place of a good inspection of the drive line. Support the rear axle on stands, shift the trans to neutral, apply the park brake. Try to turn the drive shaft as you notice the universal joints. No excess? Try to move the drive shaft up and down and side to side at the u-joint. No excess? Pull the rear cover on the differential and see what's going on in there. These differentials are a 7.5 in ring gear and will not take a lot of abuse. A reasonable upgrade for them is a posi carrier from a 4x4 Blazer or Jimmy. The carrier must be with the same axle ratio you have. I.E., a 2 carrier for a 2.73 or a 3 carrier for a 3.73. Unless you get the ring and pinion with the carrier. Next up would be an aftermarket carrier and ring and pinion gears. Next would be a stronger aftermarket differential, if you are really going to thrash it. Deep pockets for this one. Don't forget bearings and seals for the repair.

crunchy banging noises, locking up. They are easy to check for oil lube fluid will be showing contamination and with cover off tolerances are easy to measure, Front seal and pinion can be checked for projection, leaking and backlash without opening unit at all. universal joints failure should be checked for also

a howling noise when under power-if you or someone else changed the diff fluid recently and did not put in GM POSI additive it will make noise too-
