no luck yet!
a few days ago i noticed what seemed to be rear suspension movement fore and aft when going down from a speed bump.
inspecting the rear suspension, there didnt seem to be anything wrong. all the bushings were fine, the axle was ok. all fasteners were re-torqued, problem still there.
it seems to be coming from the dampers- a part of the ADS system. the damper itself had no play, and the tech theorized it could be a problem with the flow of oil in the system. stuck or gummed up valves in the system? the oil pick-up in the ADS reservoir seemed awfully dirty.
