Whirring sound

I know I've read some good info on similar problems here, but I was hoping for advice if I can be as specific as possible. There is a roaring sound from the back of the Jeep when I go over about 25 mph. It's loudest at 45 mph and decreases at higher speeds. I can feel a slight vibration of it in the steering wheel, and if I take my foot off the gas, the sound and vibration go away. I've had the jeep for about a year and have drven it this way for about 14,000 miles, without much change. The fluid level in the differential is fine.

Any help?

Have you inspected your U-joints?

There is no situation that cannot be improved with a small but well-placed explosive.

Yeah it's more than likely a bad u joint.
Pull the rear shaft and inspect the joints and if only one is bad replace both of them.
No point in doing half now and half later.
It might be a good idea to check the gear oil in your rear axle and make sure your pinion yoke isn't loose.

Another vote for U-joints.
Pretty cheap and easy to do with basic tools.

Thanks for the advice. How would I know if a u-joint was bad?
