And makes a moaning sound
Here’s a couple more pictures
Sounds like progress. I would start on the passenger side.
I got 93 B-body with a LSD. Every now and then I would hear a noise in reverse only while turning like when backing out of the driveway on the road. Not often just now and then.. Open the brakes I see nothing wrong. Spray with cleaner. Reassemble noise didn't go away. But it was not as loud. Time goes on Now the noise is loud and its happening while driving straight in reverse along with the clunk like one turn of Drive line one clunk... but again not always... U joints fell great...
I didn't feel like opening the the diff so took it to the trans&diff shop.. They called me couple hours later told me its done.. They drive it they dont hear it. Open diff,, see nothing so they did nothing just cleaned it new lube & LSD additive..... 100$ .. I haven't heard a bit of noise since...
If you remove the drive shaft and the axle turns both directions easily then the problem isn't with the rear end, what do your u-joints look like?
That is probably just brake shoe adjustment
I disconnected the drive line and I feel a little something but it’s only so often on rotation
With the brake drums on or off?
You should feel some drag with the drums on.
I feel the drag with the drums on
I wonder why you say that? With drum brakes when you are off the pedal and the e-brake is off, the shoes should not be touching the drum?
No, actually, there should be slight drag.
Simplest answer is no friction additive in it or not enough, brake issues don’t come and go, just sayin’
The OP states in his first post that the rear wheels go on an angle when turning. I cant see how that could be
Proper brake adjustment WILL have drag.
I know that it's down right crazy to question you, AND Larry, but the chassis manual describes adjusting all drums until there is slight drag, and then backing off the adjusters uniformly until the wheels are free.
That's true, but I have always left them with very slight drag. Better brake response. Too much drag, and you will smell it.
Might be a bent axle.
Anybody heard a moan when they back up with a partially set parking brake? We all have! Thats pads to drums...
But the ebrake isn't the problem.
The flexible hose is failing and is restricting fliud from getting back to the reservoir, sometimes worse than others.
Please, if you don't want to spend the money on a new hose, maybe just disconnect it at the axle and see if it helps.
I've had this problem and so have others on here, I have seen it.
That manual quote you are using is so out of date.. There was a brake arc used in those days. They were in every brake shop or large garage,,, Now they are far and few left..
Larry is 1000% correct slight drag on the drum... It can be difficult to determine just what slight drag is on a non floating axle..
