I'm not sure what they are called, but they connect on both sides near the shocks. _____________________________ 83 240D 130K 85 300SD 310K 84 300SD 131K (in reply to Mr.47) Post #: 2

I am having the same problem and the dealer is wanting over $5000 to replace it on my 95 300D. I wish I bought a Japanese. (in reply to Mr.47) Post #: 4

Doubt it's the rear diff. unless you had an oil leak. _____________________________ 83 240D 130K 85 300SD 310K 84 300SD 131K (in reply to Mr.47) Post #: 5

It whines when accelerating, but stops when approaching 70MPH, and is very quiet at 80MPH and above. The drive shaft is in the shop getting the middle bearing replaced, etc. Although the flex disc's look okay, I'll also replace them. However, I still strongly suspect it's the differential. So far I was quoated $1200. to replace it. However, the mechanic said there is little danger of it siezing, so I intend to finish some other upgrades before I tackle that very annoying whine.

Right?.Because its not leaking. And also when i jack up the car, put the gear in netural and turn the tire left to right and i hear a ticking sound, the sound is comming from u joint in front near the transmission, could that cause the sound? or is it normal.

RE: strange sound at rear axle - 9/19/2006 5:10:57 PM    Charles Munn   Posts: 244 Joined: 8/19/2006 Status: offline Air Imports, University Place, WA replaced ujoints, bearing, support and flex disks. They also balance the shaft by putting the car on a rack, attaching a hose clamp to the drive shaft and periodically marking, then moving the clamp until all vibration was dampened. It solved the "Clunking" sounds and vibration, but it still has the "whine." Air Imports said the whine is definitely coming from the diffential. They'll install a used differential for $850.

RE: strange sound at rear axle - 9/25/2006 10:57:41 PM    erashid   Posts: 7 Joined: 9/15/2006 Status: offline well folks; here is an update about my car; the noise that I get from the back initially started as a click when I go from reverso to drive; or even if I was going in drive; a month later the noise was accompanied with a grind noise all coming from the back. I took the car to two Specialized MB mechanics; and they both agreed that the noise was the differential; they both checked the flex disks ( front and back); the drive shaft bearing; and the axles; and they all were Ok. Now I am left with no option but to replace the diff; and guess what; the noise did not go; that was a blow to nearly $2000; tomorrow I am taking the car to the dealership; even though in the past they guessed every thing; I am hoping they have a solution to my car. If any one has any ideas please to let me know ( my car is a 1995 300 E Diesel). thanks (in reply to Charles Munn) Post #: 9
