Recently had the clunk noise when shifting from Park into Reverse and when accelerating at slow speed. The dealer performed a TSB nt 12-055 where they pulled the axle shaft back slightly from the hub, added molly coat grease and replaced the hub nut. It fixed the problem, but ever since that i have vibration at 61 - 65 mph in the floorboard, pedals, bottom steering wheel. I even replaced tires with new OEM Continental tires and paid the dealer to re-balance the new tires. The vibration is still there on a long flat freeway. When I accelerate from 60 to 65. Any ideas??
