I think one of my rear shocks needs replacing - it is making lots of noise. I have been reading on the forum and it seems like the Sachs SLS shocks are not direct replacements for the OEM MB parts - is that correct?
I think the faulty shock is already a replacement, it has Sachs part number 01 2400 102 256 (which I do not think is the right one). The other shock has MB part number 124 320 43 13 which I think is an original.
Based on my research Sachs 102 503 seems to be the right part as a replacement. I propose to replace both shocks at the same time along with the shock fitting kit.
