Default Clunky sound under vehicle

I have a clunk clunk...... clunkety clunk......clunk clunk sound under my Jeep. Its's an 09 Rubicon with a 3" Teraflex lift. It's been going on now for a few months. I've checked to see if any skidplates are loose, and bad driveshafts, or control arms. I've also grabbed on the wheels and pulled them to see if I had bad bearings. None of these seem to be it. Any suggestions?

Sorry guys I searched for weeks on this and nothing. While posting I tried to describe it the best way and came up with clunk. Then I serched for "clunk" and there are 20 threads. I can't find the delete thread button.

Does it get worse with speed or is it constant at all speeds over 25? Do bumps contribute at all?

Is it when you hit a bump in the road or just at 25?

I have seen swaybar links loosen up, or the bushings start to go. This will make quite the clunking with little movement. Sometimes sounds like the front end is coming out from under her.

Also, inspect your coils. I have seen them crack and also contribute to such clunking.

undo 1 sway bar link and try and see if there is play in the sway bar motor.. I had 1 replaced for excessive play causing a clunk

You've run over a smaller vehicle.

1. Come to a complete stop
2. Jack up both sides of jeep
3. Use a friends winch to pull said vehicle out from under your Jeep
4. Proceed Jeeping as normal
