Anyone know if the position of the parts are correct? Shouldn't the splines be seated all the way so it's not visible? I am thinking it's not correct if the splines are pulled out like that and is the reason for breaking the rubber sleeve.

What does tightening the 46 mm nut do (FSM calls it a clamping nut)? Does it tighten a collar which grips the splines tighter? Torque on 46 mm nut is 30-40 Nm (22 to 29 ft lbs).

Found the answer in the Haynes manual on driveshaft removal P. 157.

"use 2 large open end wrenches to loosen the sleeve nut (approx 2 turns). This will permit the shaft to be slightly compressed to simplify removal."

So it does sound like it is some kind of collar. I need to check that I didn't make that nut too tight. Should be 30 ft lbs. Don't have the special 46 mm crows foot for the torque wrench so will have to wing it.

I have removed my own drive lines on the 300D and 240D, not really much difference between the two cars.

Mark the two DL sections with something, I use cheap white Nail Polish.
This give you a reference if the 2, 1/2`s come apart, or you decide to remove the two sections first.

Remove the 3 bolts on the Diff end, leave Disk on Diff.
Remove the 3 bolts on the Trans end, leave Disk on Trans.

Loosen the 46mm Nut.

Loosen the 2 bolts (14mm?) on the Center Support.

Using a pry bar, pry the DL off the rear Disk.

Then pry the DL loose from the Trans end.

Tighten the 46mm nut.

Remove the 2 14mm bolts.

Then walk the whole unit to the rear and out.




I had my DL U-Joint replaced in the 80 240D, they also replaced the bearing and Support. 33K miles later,
had a vibration. Support was torn all the way around.


So, ordered new parts.


I replaced my center Support and Bearing. Bearing was a SKF made in Korea.

Febi Rubber Support, made in China.

Trans. Mount, Febi, made in China.

Just a heads up.

We`ll see how long these last.

Original MB support, over 300K miles, replacement 33k miles.


Got it all from this site, Febi, Reinz, and Euro were the options as I remember.
Dealer will be my next purchase.

Can`t go too wrong on the rubber/plastic Collar. URO or???
