"I picked my truck up this afternoon about closing time. They installed a brand new Transfer case in it. It is better but it still is "harsh" when I shift to 4x4 HI on the fly. It sends a jolt through the entire chassis (enough to bob your head forward a little bit). Granted it is better than it was, but I don't think it is quite right yet. Does anyone else have an HD with electronic 4x4 that can confirm a relatively smooth engagement of 4HI on the fly? They claim that there was an incorrectly machined synchronizer gear in my T-case.."
