F250 Front End Clunking Noise

When I drive, particularly at low speeds, my front end makes a knocking type noise when ever I run over small bumps or uneven spots in the road. Like something is bouncing around in there. It's almost like a hallow noise. I can't feel it through the steering, and it doesn't effect the smoothness of the ride, it's just very annoying. When I press the brakes to slow down, it goes away. Any ideas what this could be? Thanks, Jake.

Where are the swaybar links? Are they where they reconnect to the axel?

Yes, swaybar links and/or sway bar bushings. Make sure you change the bushings too. They can cause the same clunking as the links.

Also look at your front universal joints. They also make a clunking sound when worn out. Would be nice to have rubber boots on them like the CV joints have, So the grease isn't washed out of them.

Another possibility is the body mounts, or just the floor boards in general. Mytruck has made a clunking noise since I bought it 2 years ago and have replaced EVERYTHING in the front end, well really every moving part on the truck suspension wise except for the rear leaf springs. Anyways, I'm donw to figuring that my body mounts are bad, or that the cab floor is just "oil canning" and making a hollow clunk noise like you stated. Nothing in the ride is affected and the truck drives strait and true, the noise just drives me crazy(er)!

I guess i forgot to include that my truck is a '93. So it's pretty old. All of the rubber bushings look pretty worn out and cracked up. I'm fairly certain the problem isn't in the floor or anything like that. It's not the cab. There is a support from the back of the front axel to the frame farther back. Both of the bushings on both sides look to be repaired with whatever the prev. owner could find to stuff in there. I was under there today and tried shaking all of the moving parts and couldn't find the noise. It's not unbearable; I just hate it. What would you call the support I described? Would that be a tie rod? So like a tie rod bushing or something?

Who Knew?? FORD KNEW. There is a Tech Bulletin addressing this. It goes on to say that if the noise comes back to add some shim to tighten things up further.
