I went to my local tire-service shop and had my winter tires/rims taken off and the Pegs balanced-checked and installed for the summer driving season. As I was talking to the manager, I noticed that the technicans had simultaneously lifted the car at the right front passenger and left rear drivers side with two floor jacks while changing out the tires/rims. On the way home, there was a new droning sound coming from the rear end area at 54-55 mph. This sound was never there before! Someone please tell me that nothing was twisted/bent, during this two-wheel lifting, causing the noise.
