As said, if the rear has been noisy for awhile, there's probably no curing it short of a rebuild and new gear set at this point.
I would only reccomend the FRPP gears, nothing aftermarket. I'd also use the factory style crush sleeve that comes with the gears. Getting pinion depth and backlash is critical. I rebuilt my rear with new carrier and pinion bearings and 3.55 FRPP gears. Since my car had the OEM 2.73s in it, i gave it a shot with the OEM pinion shim and that worked. Took me some time with a dial indicator and moving shims around and I finally came in at just under .012, which is the limit I believe (from memory) for backlash when using new carrier and pinion bearings (highly reccomend)
It's not for the faint of heart, but can be done with time and patience. I have a mechanical background which helped a lot. The key is ensuring everything is in spec before you call it done. My rear is factory quiet, no noise or unusual sounds.
