'97 Grand Cherokee rear-end noise

[tonycl]

Most noticable at speeds 45-65. Sounds like a card in the bike spokes noise especially when coasting at higher speeds. Since it is almost impossible to be under the jeep when I'm going 60, the best I can do to locate the sound is underneath towards the rear of the vehicle. What do ya think?

Does the noise start from a start or when you get to a certain speed.
Have you tried coasting to see if it is motor or transmission or transfercase noise. More details would help.

Can't usually hear it until reaching speed of about 35-40, becomes louder(more noticable) when coasting. I can't pinpoint exactly, sounds like it's coming from the rear rather than directly underneath me though.

My money is on a U-Joint. Take the weight off of the tires and jiggle the drive lines at both ends.

Same problem here. I thought maybe it was my tranny mount. my rear wheels when spun, however do click a little....you can hear the bearings, but it doesn't sound abnormal.

I agree, I would say U joint.
