Driveshaft noise

Suspect U joint check them for play

I guess I'd suspect a noisy pinion bearing in the differential first. A tool that might help is called the "Chassis Ear". That is a set of six microphones, a switch box, and head phones. You switch between the microphones and listen while you drive to hear which one is closest to the source of the noise. You might be able to borrow this tool from an auto parts store that rents or borrows tools. Be aware that many mechanics have never seen or even heard of it, but most new car dealers have them.

Put one microphone on the differential, one on the tail housing of the transmission, and if you have a two-piece drive shaft, put one on the center bearing too.

Hi Docfixit. Stupid me. I went for the hard stuff first and totally forgot about the more common u-joints. Good thing you were here!

Thats O.K. If Ujoints check out at least have another option

Pinion bearing will be heard at Diff if coming from Dshaft then Ujoint. Do you hear any pinging noise or crackling when going from park to drive. Also D shaft if dented or bent will roar

Remove D shaft check needle bearings suspect they are pulverized
