RE: strange sound at rear axle - 9/26/2006 11:58:01 AM    timberfield   Posts: 66 Joined: 8/9/2005 Status: offline How about something with the brakes? Or a bushing on the rear suspension? Seems like you have eliminated anything with the drivetrain. You have a real head scratcher there.....Can you put it on a lift with the wheels turning? That might shed some light. _____________________________ 83 240D 130K 85 300SD 310K 84 300SD 131K (in reply to erashid) Post #: 12

RE: strange sound at rear axle - 9/27/2006 10:48:50 PM    erashid   Posts: 7 Joined: 9/15/2006 Status: offline the noise only and only comes if I was going on reverse and then forward; or if I was at a complete stop and press on the pedal; the difference between both; is that if reverse then forward the noise is click from the back; you can almose feel it; the car would move then the click will catch up; if I was at a full stop then forward; the noise will be grinding noise. it really makes no difference if I take my foot off the pedal or not; there is no noise what so ever if iwas driving forward at any speed. The axles were checked by -so far- two different MB mechanics; as well as the drive shaft; as well as the flex disks; front and back; and the bearing as well; the diff was replaced also and nothing; the pro MB mechanics now are playing the guess games with me (since I drive MB; they seem to think that I have unlimited resources for them test). any one has or had this issue; can you please let me know what the fix was. thank you (in reply to Mr.47) Post #: 16

Just a thought.... _____________________________ 83 240D 130K 85 300SD 310K 84 300SD 131K (in reply to erashid) Post #: 17

RE: strange sound at rear axle - 9/30/2006 9:18:14 PM    Syntax26   Posts: 6 Joined: 9/30/2006 Status: offline Rear Axle Bearings. If no noise when wheels are off ground, but noise when wheels on ground, the bearings are then under much more load. If races are worn badly, the bearings may be shifting when the rotation of the wheel is changed. I'd check the bearings - they can get make a lot of noise (roaring) if worn badly, though you usually only hear this at higher speeds. _____________________________ '95 E420 - dropped/sport suspension & brakes '89 300SE - Sold '89 Cadillac '00 Toyota Landcruiser '99 Suzuki 1500 Intruder (in reply to Mr.47) Post #: 18

RE: strange sound at rear axle - 9/30/2006 11:01:25 PM    erashid   Posts: 7 Joined: 9/15/2006 Status: offline Here goes another $1000 down the drain; I took it to the dealer again; they took the entire drive shaft out; apparently there is a bolt that bolts onto the transmission after the drive shaft is out; and they checked it to see if it was loose; and it was not ( $500); the next thing is the shocks ( $550); and nothing is changing; so now they think that there is rubber pieces that hold the rear of the car to the subframe; and those might be going bad; so for them to replace those it will cost me $1500; but again there is no guarantee that it will fix it. So it seems that the guess of any one any where is as good as the certified mercedes mechanics. As far as the rear axle bearing; they did check the axles; and the play in the axles ( as per the mechanic) is better than normal and most certainly it is not the axles. Any one with more guesses; I am frustrated with this car; and with the MB dealer that any other car; just any other car is better than a Benz. (in reply to Syntax26) Post #: 19
