Has anyone experienced any drive shaft issues... car makes a knocking noise when engine is stressed on an incline..... put the car in reverse on an incline... gave it some gas to back-up and there was a knocking sound (sounds like the drive shaft is rubbing against something... or maybe its the exhaust...) the car is back at the dealer..... Anyone?

The dealer tightened the rear axle nuts b/c the rear axle splines were making noise--now its gone--quiet. I had to insist that it was not the exhaust or whatever else they were claiming.
