Quick w124 LSD question

[JordaanDMC-12]

Hey everyone,

Was at the junkyard looking around and the parts car that I got my heated seats from is still there chillen.. It was equipped with ASR and it got me thinking about a LSD.

Last year I went off-roading with my w124 out in the desert and got stuck in the sand, having the open differential sucked because the old one wheel spins the other did nothing. This red w124 got me thinking about possibly maybe taking out the differential and putting it on my w124 but I did some researching and I would have to transfer the whole ASR system, not to mention rebuilding the differential and that's a hell no, already had a mess with my heated seat install, can't imagine wiring for ASR :/

But from what I was reading, Mercedes has a non ASR LSD for the w124, it's something like a grand I read, but my question is if one were to buy this from MB, is it just plug and play? I just get the part from them and pay a shop to put it in, is that easy? Or do I need all this other bs like sensors and relays?

ASD cars had LSDs. The LSD diffs are available new from Mercedes, GSXR had a good thread about it somewhere. Not sure what ratios are available from Mercedes. But you can swap the LSD carrier to your gearset.

The LSD works mechanically, so you do not need sensors.

However ASD cars also had a hydraulic pump and some sensors that would act as a true locker and completely lock the diff up to about 15mph. Otherwise its like 25% LSD at all other speeds.
