First long heavy tow trip with the X5. Used the Prodigy RF with a rental trailer. I'll start another thread for the nuances with all that. Once I dropped off the trailer, I noticed a slight growling/grinding noise on uphill left turns, slightly loaded, steady throttle. Turns out the right front outer boot let loose. They were good before I left. Lucky for me, one of the guys at the track owns a shop nearby. The X is parked until Wednesday morning. Hopefully a new boot and repack will save the joint. Overall though, with a loaded trailer weighing in at about 4,500lbs, it towed quite well.
