Mine has the same issue. I guess time to start looking at the rack. just out of curiosity, who did your lift?Strike one...the lift shop could not fix it. everything was tight, but definitely the rack. Went to the dealer and within 10 mins they locate the issue. The shop installed a bolt that was too long and rubbing against the rack when it moves. The bolt was not even tight, since it was too long(about 1/2"). The shop manager showed me and was spinning the washer that was on it with his fingers.
