Clunking noise from left front

Just noticed this the other day and thought it might have not been something on the Jeep but on the ground, did it again last night pulling into the driveway. When I turn sharp left over a small bump, it makes an audible "thunk" and small bump up through the wheel. I thought it was coming from left front but son thought it was right front.

Ideas??

Are your track bars and sway bar still installed?

Checked for loose shock mounts?

Track bars were the first thing we did to it... Sway bars are still there but with the lift and stock links that could be the problem, jsut odd that it just now showed up

with a lift and the stock links, you now change the angle with which they sit in the sway bar, and on the axle. So they just may be worn out. As far as the bushings, same same. Take off the links, see if the noise goes away. It will be mushy on turns, and lean a bit more. Keep that in mind. Try it and let us know.

Clunks from the front right usually are going to be your axle ujoint on the passenger side. Look at the axle housing behind the passenger front wheel, where the 2 axle shafts are exposed and you will see a ujoint. Check it carefully, I bet it is shot. Not a terribly difficult job to fix. Check the write up to do the job.

That was the first thing I checked, both sides, and could get no play out of them using a long screwdriver through the joint and prying up and down.... didn't get silly with a crowbar or anything but it seemed to be pretty tight.

engage your 4wd and make a left turn. sometimes the pressure on the ujoint in 4wd will keep it from clicking. Is it a one time bump or a continuous clicking?

I had the same problem for the longest time check your exhaust and see if any hangers are broken. Mine attaching to the transfer case mount was broken and causing the exhaust to hit the front driveshaft on graded turns
