I replaced my Auto leveling system with these part numbers Dorman 523-031 upper mounts and Monroe 911304 shocks, I replaced these because the dealer replaced the auto leveling units twice and the upper mounts once and I was still getting a horrible clunking noise over small bumps before and after all stock units were replaced. I asked the dealer to do this ( replace auto leveling w/ non auto leveling) and was told it couldnt be done, the service manager said he pulled the upper mounts and they were totally different. Well as usual I do not trust the dealer and ordered the Dorman mounts since they were just released 2 weeks ago and go figure, they match the Auto leveling mounting holes perfectly (as suspected) again Dealer CLUELESS. I installed these on Friday and no more noise and handles and rides like a dream....oh and no difference in ride height. Hope this helps.........
