Is this normal?

Hi all!

Trying to diagnose a noise coming from my right rear brake area so I put my car up on a lift. The tire spins freely with no grinding or other noise coming from the hub so the bearing seems to be ok. There also is no lateral movement when I hold the tire on the top and bottom and push or pull either side.



When I spin the left rear wheel the right rear wheel moves in the opposite direction and I can see the drive shaft moving in a complete rotation which I think is normal. However when I spin the right rear wheel while the left wheel moves in the opposite direction the drive shaft rotates a little, then returns to the original location. It does not competely rotate when I spin the right rear wheel like it did when I spin the left rear wheel.


Is this normal? Or does this indicate an issue?


Thanks!
Chet

That appears normal. When does the sound occur, is it constant or intermittent, and can you possibly describe the sound? [Rattling, clicking, grinding, screeching, whining, singing or, perish the thought, unearthly evil laughter?]

LOL - Evil laughter for sure!

Well...it sounds like a "clugging" noise if that makes any sense - It happens when I lift off the throttle, or when I push on the brakes. It does not happen on acceleration....

Check for bad wheel splins or wheel. Make sure the wheel is tight also.

All good suggestions and I will add checking all of the bolts that retain your shock absorbers. I've had one become a little "untight" and was able to hear some intermittant clunking. The U joints would likley make a noise if worn when coming on or off the brakes, accelerating or decelerating but not so much in steady state. When I first put my car on the road I came close to having a wheel depart becuse I got interrupted while installing one and failed to tighten the knock-off. A week later, I looked it over and hopped in. Lucky for me it did give me some warning clunks/rumbles and I was entering a parking lot. That was a lesson learned ( for the 100th time). As my signature says, I did it all myself and I was glad it was my error, because I get a bit less angry with me than I do if I'm paying someone else to do something and it goes south.
