Okay, I'm in automatic trans class for the next 3 weeks so I don't have an All-Data terminal in the A/T trans lab. I can only search stuff on breaks. I'm going to try again tomorrow. I think I found it but had so many windows open at once I lost the part number so this is what I've got so far.

1st things first, All Data has it as an ASD, I originally thought of ASD relay, but it keeps coming up in the differential section as an auto locking differential so maybe Anti-Slip-Differential?? There is the differential, an ASD valve in the right rear wheelwell, and an ASD control unit in the engine compartment on the left side (driver's side) of the block, but no part #'s for replace, just has repair orders.

2nd I was searching under different models on different years so it may be right or wrong, just information you can arm yourself with. If you can give me specifics for I am not familiar with MBs of yesteryear, I will use that to search.

With that said here goes...
