Sway bar clunk, need help!

Got this awful clunk when making turns or on uneven ground. Pretty much narrowed it down to the sway bars (front and rear), I hope lol! Tried replacing all bushings with energy poly ones, no help! Was thinking maybe longer drop links since my 01 has a 6" kit on it? Already running drop links that came with my kit, bar ends not parralel to ground, would this be a problem or could it be somewhere else? Need some help guyz, thanks!!!

I'd remove the sway bar to see if in fact that it is the source of the noise. I'm thinking its not.

Sounds like ball joints to me. I had the same issue and thought it was sway bar end links but it wasn't. 4 ball joints later the noise is gone.

Do you know how to check if the b-joints are bad?

I did my ball joints and still have the clunk. Hope it's something cheap and easy we both haven't found.

I determined on my truck that it is the connection through the chassis. The hole in the chassis and the mount that the bolt go through are both elongated slightly which leaves room for movement. When enough energy is exerted the bolt moves in that elongated hole and "bumps" the chassis. At some point I am going to tack weld the nuts to the chassis so this doesn't happen any more. For now I just torqued them way beyond spec and haven't had any noises or broke bolts yet.......fingers crossed.

Might check your body mounts too.....mine make a similar noise to the end links.

Just check ALL bolts to make sure they are tight. My trac bar was popping when I turned creating a popping/clunking noise at slow speeds in turns and uneven pavement. After i tightened the bolt, no more noise. And all it took me was finding the right size socket.

Could be something as simple as a loose bolt. So go check EVERY bolt on all your bars to make sure they're tight and on there.

Ya check bolts and all bushings up front. Mine clunked like that and had broken bolts on track bar bracket. Then it come back like 3 months later and it was the track bar bushings. I just bought a adjustable track bar since I leveled the truck now.

Mine does the same thing, havent fixed it yet but found some wore lower shock bushings check them too but anytime i have a clunk or rattle I check shocks, sway bar and track bar. Then if its not any of them go to checking the tightness of all suspension bolts.

I guess I am having the same roblem you guys are. Mainly when I drop off a curb/truck flexing. Checked end link bushings and they were shot. I replaced all end link and sway bar bushings. All tie rod ends and track bar just for the fact that they were the origional ones (almost 300,000 miles) new shocks. And I still have the noise.

I feel like the only thing left to check are spring/shackle bushing and bolts. I have replaced both front hubs and ball joints twice only thing else that has not been replaced on front end are the u-joints at the hubs, but there is no play in them.
