What were the specs? I've read here frequently that Mercedes has been the only reliable source from which to get a good alignment done. My car (1982 240d) wanders as well, and I see in the records that someone did a "rear thrust alignment" at some point in the past. Makes me wonder since the rear is supposed to be non-adjustable factory stock. There are bushings for that, but I dunno if I have them installed or not. Someday I'm going to tear apart the rear and find out what's going on back there, installing new bushings, springs, shocks, subframe connectors and diff mount.
