Rear End Noise 8 3/4

I agree with the comments of "once noisey always noisey" and no way is quality work gonna happen for $50. Work at a 4wd shop for a little while. You eat and sleep gear swaps and repairs. The rule is if there is a whine and there's more than 50miles on them, expect worst case. I have the checking bearings and tools to do them. Case spreader too. And I wouldn't dream of saying an hour. That's enough time to run a pattern, carefully take it apart, and clean the stuff. Never mind fixing it.
