Replaced the side seals on the differential - PeachParts Mercedes-Benz Forum

I swapped diff a month ago but the one I got was leaking from the pinion and I learned a wee too late that it was not a good sign...
Anyway, I took the old diff and just replaced the side seals as it was leaking, next week, I'll do another swap. Here is today's work with few little tricks I learn along.
The clips inside were a pain for me to remove. A coat hanger gave me enought grip to get it out

For removing the old protective plate I used a plier and with a bit of leverage, it went all easy.
To install the new plate I used 2 piece of wood and a hammer, it did slightly bend it in one corner, but nothing bad.
To take the old seal out, just inserted a long tyre removal bar and hammered the bar away from the diff, it just pop out no bother.
Make sure the breather is clean as if its blocked, the pressure will damage the new seal...

I think its about it.

Make sure you get the right size. There are two different size seals that changed around the 81-82 years.

Hi Olivier,

Is there no gasket between the rear cover and the diff housing?

Hello NC,
No gasket. It actually look like there was only a yellow varnish, nothing to do with the black silicone at all? I founded this odd... The "varnish" is hard and brittle.
