hello all! thanks for all the responses on this issue. was finally able to get under the car while it was in the air; by turning the wheels by i hand was able to fairly consistently produce Bad Noises from the vicinity of one of the Axle Shafts. they're on their way to the Retirement

I.E. my coupe. The axles were rebuilt by the MB dealer less than 10kmi before I bought the car, they didn't last 10kmi of my driving. Luther Kaleb C. Striplin wrote: does it look like maybe somebody replaced the boots at some point? I have seen boot replacements that dont turn out very good.

hi! i don't have any indication that they're anything other than original; they look to be identical on both sides, and give the appearance that they may have been there the life of the car,... (i bought it 5 years ago with ~121K miles on it in SoCal, and put the last 50K miles on it. it

thanks all for the suggestions on the driveline issues; based on my undercar inspections (nothing visibly out of sorts), observations (intermittent nature of noise, tone of noise, lack of vibrations, and frequency related more to wheel-speed than driveline speed) and other hints/tips from the

Please check both flex disks immediately! I had a rear one let go, same noise, but severe vibration because a big chunk fell out. ANY distortion, cracks, or signs of the inner cord being visible means the flex disk is bad and failing. The rear one won't give you too much trouble (mostly

I vote for bad axle CV joint. That noise and behavior can be intermittent, at least it was on my TD, seemed to get worse longer I drove it, I guess it was getting hot or something. Do you notice the noise or whatever in reverse too? Did you jack up the rear and rotate wheels by hand while

You probably have a torn boot on one of your rear axle shafts, which it turn causes the joint to go bad. The noise will come and go for a while till it finally comes for good. Just get a good used one and be done with it. ernest breakfield wrote: hi gang! time for an invitation to play

Once one has experienced a few of each type of problem, one can usually determine whether it's driveline or wheel because of the base frequency of the noise: driveline is at about 3x the frequency of wheel noises. That helps narrow it down significantly. I had a rear wheel bearing go out once
