Hum Starting at 55MPH
Please help me. Had the brakes flushed at a local garage which went well but they noticed my cv joint on my front driveshaft had play. They wanted a grand i said no thanks. Ordered a whole new shaft with a new u joint and CV joint and installed today. Torqued all bolts as specified. Same shaft as orginial as far as length. Drives perfect all the way to 55 then i get a absolutely horrible low pitch hum that was never there before. Driveshaft did come dynamically balanced out of the box. WTF! Please help ideas there is no play at either end at all brand new shaft. What do i do? Bring it to the shop that originally wanted to do it and have them put it on the lift and listen??
