Does anyone out there know what may be causing a "clunk" noise in the Driver's side front suspension on my '02 F250 4X4? I am not the only one that I know with this problem and we can't seem to find it. I have had two local shops check the bearrings for movement, but everything looks tight. Put all new shocks on to no avail. Clunking noise is only noticible at lower speeds when the driver's side suspension is compressed due to a bump and can be felt through the floor board. If any one out there has any ideas, we would really appreciate the feed back. Thanks, Todh

i have an 02 f250 4x4 with an 8" fabtech lift. i would routinely have to retighten my front sway bar links to keep them from making popping noises when i hit bumps. more recently i got stuck in a ditch and had to be pulled out by a tractor. ever since then when i turn to the right and hit a bump(like a driveway, etc.) i get a big thump that i hear and feel through the floorboard. it only happens when turned to the right. i thought it might be the tie rod hitting the lower track bar mount. i had my wife duplicate while i stood by to watch and that wasnt it so now i have no clue. probably gonna take it in.

Endlinks, Endlinks, Endlinks. The bushings have gone bad and need replaced. You can get polyurethane replacements from Energy Suspension for $36. That includes everything you need for the whole swaybar. One other possible source for the noise could be track bar bushings. Either way, it is a pretty easy fix.

its not the sway bars. i disconnected both sway bar links and truck still clunks when turning right and hitting a driveway, etc. i checked the track bar mounts. both were tight and looked fine but i wasnt really sure what i was looking for. i noticed that i could pivot my drag link pretty easily with one hand and it would make a clunk. is that normal? could being pulled out of a ditch(it was a hard pull with a tractor, not straight but to the left) damage the ball joints or leaf springs? /ubbthreads/images/graemlins/confused.gif

Todh,

If you can feel the "clunk" with your feet, I'd be for checking the spring bushings, namely, the rear ones on the front springs. They have a nasty habit of wobblin' out and letting that spring come up.

Sure doesn't sound right with that new of a truck, but somewhere the sprung and un-sprung weight of your truck is crossing paths.

I dont know if you have a lift or not, but if you do, or you had any anything done up front, I would check the trac arm. You said it was tight but it needs to be torqued correctly, or it will make a "clunk" sound as you described, especially in turns. They ar often too tight and that could be the problem.

Mine was doing the same thing, I could feel it on the floor board. I felt pretty stupid when I found out it was the shock bushings. Cheap fix though. Good luck.

i disconected the shocks entirely to test for that but it still clunks. as for a body mount issue, i did notice that the two body mounts under the driver and passenger look like they might move a little because the undercoating surrounding them is a little scraped away and when i checked the other body mounts none of the frame undercoating was disturbed. they look like theyre tightened from the inside of the truck. any help is appreciated.

Hey Guys, Good News!!!! After trying several of the suggestions made to this post, I ordered and installed new end link bushings from Energy Suspensions. The new bushings helped but did not solve the problem entirely. I replaced the upper and lower end link bolts with newer snugger fitting bolts and the noise is gone as well as the occasional popping sound. I have an aftermarket leveling kit on my truck, so your bolt and endlink sizes may be different then mine, but don't stop at the bushings themselves if the noise continues after replacement. The fellows at Energy Suspension were great. They went above and beyond the call of duty when it came to getting me the correct sized bushings for my application. A big thanks to all of you for your helpful advice.

I had a clunk whenever I hit the brakes. The balljoints were toast.
