Rear Breaks (or axle?) Clunking

Ok, after going through 10 pages of old posts and looking through my repair manual, I can't figure out my problem.

It's only happened 3 times, twice yesterday and once today. I was driving down my driveway and I felt/heard clunking coming from the rear of my Jeep. It happened when I backed up to leave a parking lot, and it happened when I braked this morning on my driveway for a passing car.

I replaced the front disc breaks about a year ago, so it's not that, plus I'm 100% certain that it's coming from the back.

Any help on this ASAP would be great, it's finals week and I'd like to get to them on time!

oh yeah, I heard the back breaks squeaking when I was breaking downhill on my driveway this morning after washing it. (totally off topic, but if your black bumpers and door handles are looking dull, add some of that Armor-All black chrome stuff to it, totally makes it look like you drove it off the lot!)

Sir, yes Sir!


Everything looks normal, nothing is loose or falling off. It's quite dirty under there though...it'd be nice to get all of the winter dirt/sand out of there and make it look new. but that doesn't matter right now.

It happened again when I backed up to leave work, and when I rolled down a small hill. it's coming from the back, it's a grinding noise and it's kind of bumpy.
it only happens when I first start driving, it doesn't do it after I get rolling. I hope it doesn't need a costly fix, I'm a poor college student! And I hope I don't have to take it in to the dealership, there's no way I'm going to get caught driving a cheap rental POS.

Maybe your breaks are broke...

My dad looked at it yesterday, and he said it's most likely the U-Joint like you said.

And now it's not doing it. Whatever...

MOst likely a U joint....If youve mashed your skinny pedal too much what can happen is you blow the retaining clip and cap off one or more of the ends of the Joint. Then the ear floats in the yoke and any time you change direction it taps on side or the other. You can technically run with it for a very long time, but youll eventually need to replace it before it ruins the yoke.
