I noticed last night when driving the '80, a squeeling noise coming from the right rear of the car. Sounded like a tire turning on a clean garage floor. I pulled over and looked but could find nothing wrong. The tire and wheel was not hot. So I got back in the car and drove home and did not notice the noise. This morning when driving to work I got about 20 miles into the trip and it started doing it again. You can hear it from 1 mph to about 20 mph. When the car stops the noise does to. I got to work and checked it and could not find anything wrong again. What could be causeing this noise? Rear bearing maybe?

Somebody has to have an opinion on this. I was just thinking that I put the parking brake on several days ago. Do you think it is possible that the parking brake did not release all the way and the squeel is coming from the pads? Is there a way to check this?

Thanks

Several things could be causing the noise but the 1st ones I'd check would be the brakes and then I'd check the wheel bearings. Sometimes dust will cause a squeal. Also saw a post the other day on the Forum where the emergency brake was the problem. :cheers:

Few things I would do.
Jack up the car and remove the wheel on the side you hear the noise from. Checkt he parking cable to see if it's retracted or stuck,have someone pull the handle up while you look at it. You can remove the cable if you have to. If your noise goes away hten the shoes are probably rust seized and dragging. If you still have a noise then check the U-Joints for play and rust. I like to dsconnect the 1/2 shaft from the spindle with the caliper off. This will let rotate the rotor by hand to see how it feels and sounds. There should be any play in the bearings and if it's thebearigns making the noise then there will be some heat buildup in the area. A lot depends on who was working on the car in its life,you may find some interesting things once you start looking.
Good luck,

I'm having the same problem - squeals like a stuck pig, then goes away sometimes. Since I replaced my u-joints a few months ago it leads me to believe the bearings are going bad. I've been reading the archives about bearing replacement...sounds like a tough job to get right. And, I thought rebuilding the engine was going to be the worst thing to do. :mad

Yes, That was my problem........a little squeek turned into a BIG grinding noise. It appeared as though the keepers and the adjuster had come off my e-brake inside the right rear and was locking it down....chewed up a U-joint too. :auto:

Try leaving the line at something a little less than WOT. :D

Update: When driving home last night it started making the noise. So at 10 mph I engaged the e-brake and the noise got lounder which leads me to beleive that it is in the ebrake assembly somewhere. Is it difficult to change the e-brake pads at the rear wheel. I guess all the springs and stuff should be replaced while I am in there.

So I think I am going to get a rebuild kit for the parking brakes. I have read that the rear rotors are rivited onto the hubs and that you need to drill or torch them off. My question is do the rivits need to be replaced or do you just assemble without anything in the rivit holes.

Drill them out, no torching. Replace the rotor without them.

I'd still bet on the bearings going bad. When you apply the e-brake while moving you're putting load on the assembly.

On a previously owned0 '75 I had the same type of squeak from the right rear. Driving home one night the bearing completely froze on the spindle, actually twisting the spindle in half at the mid point. Wheel/tire ended up horizontal in the wheel well and the car riding on the suspension. Fortunately I heard it coming and manged to all but come to a stop when it let loose (thank God!).

Check thy bearings, man!

Well maybe I should just replace the whole assembly so I know that it is good. This seems like a good price per side. About $575 including all shipping. After reading all the nightmare post about the rear bearing installation I would never attempt it.
