Noise in rear end

As you can tell I'm new here so hopefully I can get some good advise.
My 94 has developed a clunk in the rear end. If I put the jeep under a load, like jumping on it off the line or allot of rpm in the dirt it makes a loud knocking sound. I have been told from some friends that it could be the bushings in the rear end. If that is the case are they easy to work on. Thanks for any advise.

"Noise in rear end"
Don't eat so many beans! JK

U Joints are the prime suspect.

^ Ya beat me to it. I was going to suggest the best way to fix noise in the rear end was to take some Beano.

I would also have to say u-joints, because it is the easiest to diagnose and repair if you have noise back there. Try and wiggle the shaft to see if you have any slop. Another to try is to put the rear end on jack stands, grab a buddy, have them get in the jeep, start it, put it in gear and "drive" the jeep on the stands. 2 words of caution if you do this.

1. Make sure the jeep is pointed in a safe direction in case it come off the stands.
2. Don't put yourself in a position to get run over or squished if the jeep comes off the stands. Just use your head and be safe.

I just remembered I had a knocking sound in my rear end a long time ago and it was the e-brake cable rubbing on the inside of the tire/wheel hitting the wheel weights. Probably not your problem but its easy enough to look and see if that's what it is.

Are you SURE it's not your U joints? That description screams bad U joints.

Maybe the thing to do is just replace the u joints and see what happens. They are simple enough and cheap to do.
