You may be having issues with axle bearings and/or clutch packs in the posi unit. Do you know when the last time the rear axle was serviced? If not, I would think about getting your car to a shop that specializes in rear end and driveline service and repairs. Here's one that I know of nearby that you can check out for yourself:

That's great information, Michael, thanks! I know right where these guys are, too, and since the paint shop is in the same area, I can take 0327 to RS first, then to the paint shop in the same trip.
I hope continuing to drive it now won't do it too much damage; on the other hand, all the clutches and wearable parts will have to be replaced anyway.

The "auburn type" (1981-84) limited slip differential is much different than the 1985 and later limited slip differentials that we're used to. No replaceable clutches. Pre-load spring assembly is also unique and frankly, a piece of crap. You could replace with a 1985 and later diff and be on your way. At least then it would have replaceable clutches and a pre-load spring that won't explode and leave metal shrapnel in your carrier.

I have no idea if anything has ever been done to the differential.
That's something to consider seriously, changing out for an 85 or later differential; thanks for that suggestion, Mick. Would I have to change the whole axle, or just unbolt and swap out the diff portion? I'd probably get an 85 or later, take everything to the shop and have them install it with new parts.

I did some web surfing for information and I think I would have to swap out the rear end to do that (replace with an 85 or later).
I found a rear end from an 88 GT on Craigslist, complete. Would that work?

Steve, check the diff cover for any fresh rtv sealant. I am 99% sure when I had the car worked on I had the fluid drained and replaced. If I didn't, shame on me but I am almost positive I did. I did not change the wheel bearings nor did I get into the drum brakes. There are quite a few things within the drums that could be making some noise. I'd recommend doing the rear bearings anyway. Fronts have already been done.

That's an 8.8 rear end as opposed to your 7.5. It can definitely be done but for the sake of originality and retaining the slappers bar set-up, the 7.5 is the way to go. I believe '86 is the first year of the 8.8.

Thanks for the advice Jon. I think next week when I take it in for the smog check I'll ask them to check out the brakes, bearings, and fluid. Better to start with the easy things before diving into a big project.

Never did the rear brakes because I believe they were in good shape. Looking forward to hearing of the fix.
