D44 making strange noises

My 73 D44 with factory limited slip is making some very loud almost rubbing like sounds. I also feel a vibration in the floor while this is happening. There seems to be no real pattern to it,except when I stop,its gone until it starts again. Whenever......

Diff oil looks ok and is full.

Any ideas???

I'd pull your differential cover and inspect your Trac Lok clutch retainer clips. One of the clips on my 72' came off and started allowing the clutch discs to rotate. One common thing with the clutch discs in those old Trac Lok's, when they start getting old and worn, they get loose enough to let the clips start to move around and eventually come off. They can really start tearing things up if one of the pieces get caught up in a gear.

If it's not a clip, at least by taking the cover off, you'll be able to do an inspection. The clutch kits are under $100.00, and are pretty easy to install. I'd have a qualified shop do it though. It does require a few special tool's and only should take a shop about 1/2 hour shop time if you bring them the differential.

In the picture you can see the distorted retainer clip.

Make sure your using a friction modified lubricant. Straight 80/90 can cause clutches to chatter.

I did some investigating,in doing so,I found the left rear caliper is hanging up. Now,I'm starting to think my problem is a brake issue not the clutch issue I thought it was going to be. I hope it's not both......

Update:

Not brakes either.......turns out, its a bad wheel bearing. Oh well, better than differential!
