clunk when braking!
iam having trouble figuring this one out....(01 f350 4x4)when i apply my brakes,i get a clunk type sound from underneath my feet......it doesn't do it all the time....also,if i get it to do it,it seems like i have to wait a bit to get it to do it again...iam thinking it has something maybe to do with brakes/calipers...it almost seems like it has to"reset itself" so to speak before it will do it again.I quickly poked my head under there this morning before work,and i did notice that the caliper seemed like it had a little movement in it...it was the same on the passenger side though,and i only get the noise from the drivers side...just wondering if anybody had any ideas...iam sure it is not link end bushings,stabilizer bushings,ball joints,etc.....because i just recently did all that...it definately seems to be in the brake setup somewhere....thanks for any input!

Your ball joints are worn. When mine started to go, it would only do it when braking pretty hard, but it was a nice loud thud. Jack the front end up and try moving the tires around with a long 2x4 and see if the joints have play. If they do, RacerGuy has a good writeup on ball joint replacements. https://www.ford-trucks.com/forums/3...ll-joints.html

Hmmm, guess I read too fast. Keith is probably right.

I have do disagree with the ball joint idea, though it is possible, I just did my balljoints 25K ago and am experiencing the same thing by the sounds of it. Only mine seems to be coming from the rear brakes

Intermittent noise under your feet while braking .... a "thump" .... driver or passenger side ... comes up often here on this forum. In addition to all those things you already changed, some people have said the cab mounting bolts/bushings/etc. I've never even looked at mine, but I will.
There should be no play in the caliper area, no? The calipers are bolted on, and the pistons/pads should be snug against the rotors.
I didn't think you would hear a sticking caliper slide pin "releasing." When we apply the brakes, isn't the movement only hundreths of an inch?
I learn new stuff on this forum everyday.
Let us know what you find.

Pull the caliper pins and grease them up good... it wont hurt to do anyway
