Has anyone else run into a serial differential swapping issue? I have been
through about four differentials in the past year on the 300td and the

I had similar trouble with my '85 190D. It got very loud before I replaced it
and the replacement was just as loud as that which I removed.
The problem here would be, apparently, the fact that they're so good in the
first place. Remember we're talking about nearly 40 year old cars here. It's

My 1987 300TD had a whine somewhere aft. So being a genius I replaced the
diff assembly, and it still whined.
Center bearing, only six months old, was talking to me. Replaced it and
viola quiet as can be.
YMMV.

You need to find a differential shop and send them over.
Other than a major component, like a ring or pinion, I can’t imagine they
couldn’t rebuild them back to new.
Let me ask around…

Contact Pierre Hedary and ask him.

Yeah he has responded to my emails before. Usually telling me to contact
someone here in CA that I or my mechanic have already talked to. But it is
nice to triangulate.

Yeah I should think any competent shop could give it a go. But Herbert says
the rebuilt ones tend to fail about as often as the junkyard ones do.
Nobody seems to have the jig they used to determine the pinion position
with the least whine, or maybe it was the shim thickness for the axle stub

I have a 420SEL rear diff/axles but I think we are a continent apart so

I get it, I hate being stranded on the side of the road. Hopefully you're just
having some bad luck. Of all the cars I see broken down on the shoulder, they
are rarely Mercedes.

I’m told that the only trusted people to do differentials is Stu Ritter’s
former shop in Denver and Blue Ridge in Atlanta.

His Youtube videos suggest he is quite approachable. I think I would try

He must have encountered differential problems and may have a solution.

I have a “new” 2.24 W126 diff, if that’s useful to you! I bought a parts
stash and there were several new from MB diffs in there, NOS.

The original differentials in the 85 wagon and the 88 560sel both started
to make progressively louder whirring sounds, so they were on their way
out. I replaced both. Wagon had about 211k on the clock and the 560 99k.
Not nearly the hundreds of thousands others seem to get.

Interesting. The wrecking yard here has two more in stock so I will
probably just keep swapping until I get a good one. Thanks.
There is a guy here who claims to have the setup to do a rebuild also. They
are in Irvine or somewhere. He sold me the 500e rear subframe for my 87
wagon project.

Yeah me too. The unblemished record for us is getting shakier, though.
The 85 wagon left my wife and kids on foot when the master brake cylinder
failed and applied the rear brakes continuously. That was unexpected. The
AC fuse melted through the fuse block when the nanny was running the AC
continu

I had that happen on the 190D. A few strokes with a file cured that.
(The release valve wasn't depressed properly when the pedal was released.
Poor tolerances on manufacture, I believe.)

Question:
What oil have you used in the diff's that failed?
Ring and Pinion gears are held in strict position by properly shimmed
bearings. As long as that strict position is maintained, they will run
silently. As soon as shim or bearing wear happens the relationship of Ring
to Pinion shifts, and b
IF the owner ever took the car to a "quick change" oil shop, and got sold by
the guy holding a dirty rag in their face saying "your differential oil is
dirty" then who knows what it was filled with.

All good thoughts. The LSD in the 560 was running the special factory LSD
sauce when it died. No guarantee it had that all of its life.
The wagon ran whatever mercedes recommended for the 120k before I swapped
it out. It had about 80k on it when I bought it and was a two owner car I
think.

Thanks, thus my point in asking, what oil was used..
