I thought I would try again, does anyone here know of or could maybe recommend anyone that can overhaul, restore, refurbish or sell a replacement axle differential please?
OK if you were to look for a second hand unit there are several things to look out for. For the automatic box there are two different types
A2013505820 for non ABS models [ earlier]
A2013500964 for ABS models [later]
Both with a 1/ 3.23 reduction ratio.
The ABS model has an addition sensor/wheel on the diff meaning you need this type if your car has ABS brakes.
There may also be differences in the half shaft flanges and this is best checked visually by comparing old and replacement differentials REAR AXLE HOUSING WITH DIFFERENTIAL MERCEDES 190 [Car] [CHASSIS] (EUROPA)
