79 rear end squeaking low speeds
I have a peculiar problem on my 79. I currently have a squeak in the rear while driving at low speeds (possible at higher speeds but cant hear it). It sounds like squeak squeak squeak. It does seem to go with the speed as it does get faster as i go faster. The rear wheel assemblies have been replaced and i just replaced the half shafts thinking it was the u-joints. Still have the same problem. I also was thinking it was the brake pads so i swapped them 2 times and even another new rotor and still nothing.
I took it to a corvette maintenance shop and they thought that it was my side yolks as there was a crap load of play but that turned out to be 3 missing bolts for the diff to frame...freaking bubba strikes again
anyways...the squeak is still there and it is driving me crazy.
Anyone have any ideas?
I also have another squeak in the passenger side rear brakes. when slightly applied, they squeak but with about half peddle+ the squeak is gone.
This is so frustrating.

have you tried installing the anti-squeek kit on the brake pads?

When i had it at the shop, they had it up in the air with wheels of and had the car running, in gear, and accelerating. no squeaks then, but they did not use the brakes.

You say the rear wheel assemblies were replaced what do you mean, the actual wheels? wheel bearings? Is there a difference in the squeak ("loud" or "slight")? Was the squeak there before the wheel assemblies were replaced? Is the squeak coming from the right rear brakes the squeal you hear? I'm suspecting rotor runout. Wheel bearings squeak every two revolutions of the wheel(s). If it is the bearings which I do not think are the source of the squeak the noise will worsen.

I thought run out too. The shop I took it to said it is well within spec.
The sound is constant while driving at low speed and just gets faster as I go faster.
When I brake the squeak I hear from the right rear brake is loud and when I press harder on the brake it goes away.
I think this 2 squeaks are different

The one thing I did though was used the adjuster to be in them more into the hub. I dont think the pads moved though. I wonder if something is hung up like you said.
Weird thing is...since I have been working on this, the last thing I tried was thinking that the diff fluid could be low or something not lined right. I started making some sharp circles in a parking lot in both directions and now the drivers side seems to have a small squeak when driving now too....I dont know if this is real or just the passengers side getting worse.
