All W124's in the USA with the DOHC M104 engine use the 2.65 diff, which I believe is MY 1993-1995.

Find one with an instrument cluster and the driveshaft, to swap and you'll be set.

So if you have access to a 1994 W124 wagon's diff, driveshaft, and speedo, you're set.

The 400E's use I think a 2.24 diff, but it is 4-bolt configuration, with different splines, and a different cover.

Thank you!
So i need to swap driveshaft as well? On 95 wagon half of the driveshaft as removed by someone..
I think in 94 sedan driveshaft is in the trunk. Do i need to balance driveshaft, if its been removed and no markings on it?

Thanks in advance!

on BMW e30's the driveshafts are marked on each half with a white dot. I am guessing there should be some type of marking. In BMW's the myth is you needed to balance the driveshaft complete (both halves together). In our several mix and matches, there was no vibration coming from the drive shaft as long as the makings were lined up. Each half was balanced on its own. Not sure this is the same for Mercs, but the driveshaft design is very similar.
