Clunk Killing me...

So I've been chasing down a clunk in my front end for the past few months, and it's killing me. 211k on my 2004 F-350.

I feel it in the floorboard on the drivers side, right under my left foot.

Here's what I've done so far --

- ball joints
- sway bar bushings replaced w/ Energy Suspension poly
- new track bar built by me w/ heim joints

Any thoughts? I'll do anything at this point.

Thanks!!

Did you torque the track bar? It takes alot to tighten.

I have seen super duties with broken body mounts there also. It' a pretty common clunk, but most stem from the track bar being loose.

Check where the springs mount to the shackles and the shackles to the frame .

How can I check the springs and shackles? Where can you buy replacement bushings for those areas?

I have tightend the mess out of the track bar I built, so I dont think thats it.

I mostly hear the clunk when hitting small bumps, and I can re-create the clunk when quickly turning back and forth when driving, but not while sitting still.

All shock mount bolts have been torqued.

Thanks for the help!

I'll look for a broken body mount. It would make sense since I can 'feel' the clunk under my left foot. How can you tell the body mount is broken?

Try to lift the cab from the frame. I have only seen a few trucks with broken body mounts, some of them were rusted really bad.

Like is said most of the time its from the track bar being loose.

Did you replace the sway bar bushings themselves or the link bushings?

I replaced the sway bar link bushings top and bottom, as well as the bushings on the sway bar connecting the bar to the axle

Just checking. I replaced my links and still had the noise. Replaced the bushings and it was fixed. The track bar is suppose to be torqued to 400 ft. lbs. I believe. Anything less than that and a clunk noise is possible.

NCfarmboy, I have the exact damn problem. You described it very well I must say cause this has been brought many many times on here but poor desciptions along with even poorer answers is all you'll rummage through.

I'm gonna run through everything on mine in a month or so when I get home as far as re-torqueing all susp components and perhaps try swinging a lift arm under the front corner of my cab and lightely raise up on it even though my truck is 200% rust free (Nevada truck born and raised ) to rule out cab mount.

I'm stubborn to admit it but since the track bar is the most common answer on here, it makes sense because my pop is most times worse while steering (Typically left turns)
