04 6L clunk under drv sd feet

[h_bomb41]

Newbie here. My wife, yes I said my wife, has a 04 F350 6.0L diesel 4x4 crewcab that she calls her 1 ton grocery getter. Anyway, she tell me she feels something "clunking" under her feet when driving over choppy bumps at about 20 mph to when coming to a complete stop. The truck has 28,000 on it. Any ideas on what this "clunk" might be? Thanks for your help.

loose track bar or sway bar.
or bump stops loose. I read somewhere about the retainer cap coming loose and making odd noises, but i cant find the TSB.
the one below is not for your truck, but it might help as a guide

Lifted?

When I lifted mine, I put the bolts in backwards on the front sway bar. It clunked every now and then against the springs until I noticed what I did.

I did read and I realize thats what you said, but the correction does in no way relate to the 04. They are not the same that's all I am trying to say. Most of the issues with the 04 and that is the drive axle and 4x4, but she's having this issue in 2 wheel, so .................

Welcome to SDD there h_bomb41

There's one body mount bolt under the drivers feet that is a common problem on many Excursions that have also been exhibited on some SuperDuties as well,the fix is alongating the holes open about 1/8" to prevent the bolt from tapping the body to frame seat when going over bumps and body flex.

CHPMustang!
I'm going to look into all suggestions this weekend and I will let all know if and what the problem was.

if it is a "clunking" noise when going around turns, or hitting a pothole in the road, or even clunking when pulling into an uneven driveway, it may well be the swaybar bushings at the axle to sway bar connection. we have two trucks that exhibit this that need to be fixed. you could get stock replacements, or go for the gold with Energy Suspension's poly units. they are virtually wear-free, and should last the life of the truck. part number 4-5186 for red, if memory serves me correctly.
