(Front end prob.)"Clunk" sound while rolling to a stop.
Two nights ago drove home in some snow stuff. I used 4wd. Last night night I came home and parked in my driveway (2wd). While rolling to a stop a tapped breaks and heard the "clunk" from the front left. Not too loud but I noticed. I backed up and rolled up, it did it again. No sound while backing BTW. The Beast is a 93, 5.0L. It has 114k miles. There was no pull or push just a slight "clunk". I am the 2nd owner and I don't think the U joints have been touched. Oh yeah I have a slight pull to the left if I brake just a little hard while driving on the road. The tie rods and steering appear to be fine. The brakes were replaced last year before I bought it. Is it U joint time or what. I want to start with the easiest and work my way up while troubleshooting. Thanks guys...

It sounds like your pads going to the foreward stop position. I have heard this before also. If you have a pull to the left while braking hard, either your right brake is not working or the road is slanted to that direction.

So you are saying check the front brakes first? The road is fairly level when it pulled to the left. I think the previous owner did the brake job himself. Who knows what I will find. Could it be that simple? <crosses fingers> The sound was so soft that I hope it is the brakes and not the U joints. I would think, and I am only guessing here, that the U joints would be a bit louder if they were acting up. Hopefully just a coincidence on the 4wd useage and the sound. What is the best way to check for U joint slippage or wear? Thanks again...This forum rocks!
I would be inclined to think that you would here u-joints more during acceleration not braking.
I really think that it is your brakes.
Now that I went back and read your post again, I would bet that the piston on your left brake caliper is sticking. That would explain the pull as well.

Any easy way to tell if the caliper is sticking? If it is whats the best way to free it up? Maybe I will be real lucky and the cold ice from the drive in the snow kept it locked. Now that is warmer it could be free'd up???<crosses fingers again> i will look at it on Wednesday afternoon. Thanks again guys....This forum rocks!
you might be lucky, but if you do have to check the brakes make sure the sliders are free. i've done LOTS of front brakes on fords and that's what the problem usually is if their driven in the snow. if their ok, i'd replace instead of trying to free up the caliper. if you don't your more than likely to have the same thing happen again. i've got a 93 myself, and knock on wood, no major problems. if you need body parts, send me your email address and i'll send you the address of a really good guy to deal with, he's super honest(a real rarity these days) and only deals with ford parts.
I had what sounded like a very similar problem. Next time it happens quickly reengage the 4x4 and see if it stops, if so then your hub or hubs might be bad. At least that is what happened to me.
My truck pulled to the left really bad before the brake overhaul. apparently the schmoe who did the last brake job did wrong, so that it warped the rotors. it felt like a flintstone car when slowing down for a light. $860 dollars later and new everything in there, brakes like a dream. stupid dummy...... thats what happened to me. -wb

Well I finally got around to ordering my new Auto hub assembly. As it turns out Ford new that there was a problem with the original design of the auto hub, so they rededigned it to be more reliable. You would think that they would issue a recall on this, but no, you have to wait till it fails then pay for the new parts. So for now my passenger side will have the new version and my drivers side will have the old version. According to the Ford Tech you don't have to replace both at the same time.
Well I checked it out this morning. The "clunk" is gone. I found a small puddle of water under the suspected tire. Must have been ice and snow up in there after the drive. The pull is worse now. Thursday is supposed to be warmer....I will take of the front tires and start looking for calibers grabbing or not and brake inspection. Anything in particular I should look at. I think the rotors are slightly warped. The front of the truck has a slight "wavy" feeling while coasting to a slight stop w/ the brakes in the front. Thanks again guys...
check for rust on rotors(especially the backs) and all brake parts. an easy way of telling if the calipers sticking is if one pads is worn more than the other. if you need to buy new parts don't go the cheap part route, you get what you pay for. you might even want to check your ford dealer for motorcraft replacements, sometimes they're actually cheaper than the aftermarket.
If it drifts to the left when you apply the brakes on a level road, it might be "recession steer". Ford has a technical service bulletin on this problem with Broncos. Their fix is a new set of bushings that are firmer on the left than the right. It's the bushings on the arms that go back from the front suspension to the frame. They compress when you hit the brakes and the steering goes slightly left.
