Front end clunk - what to check?

[2003V8LTD]

FWIW, I had a front end clunk. Replaced sway bar bushings with urethane ones that I found in a very low durometer. Problem completely went away and the overall dynamics of the car are very good now.

I’ve been trying to chase down this ‘clunk’ that happens when going over a concrete drain curb, or turning while backing.

When I back up and do almost full turn of the wheel ( when backing from my driveway out of the garage to run and then exit my drive) I hear this significant ‘clunk’ and can feel it in the steering wheel.
When turned and going over the drain curb to my drive, I hear and feel the same noise. Backing from most parking spots I get the same.

It’s not a ‘click click click’ that you would expect with a CV joint.
This weekend I put a wrench on every nut I can find. I put 5100’s in 3 years ago so I know the suspension well.

I had a bad wheel bearing on the passanger side that I was hoping was responsible. That’s now replaced.

I lifted the wheels and all tires are solid, so wheel bearings are good. I feel no wiggle in any joints as I try to move the tires while up on the jack. All feel tight.

I’m wondering what this group suggests to check. I can’t find anything loose, but it’s some clear suspension clunk when turning tight and/or going over a dip at low speed. I don’t hear it over normal bumps and pot holes while driving.

Any ideas would be appreciated

This is different than the Swaybar bushing clunk, which have already been replaced because there was a clunk a few years back.

Unfortunately the only person in this thread who had the problem solved replaced everything so we don’t know which was causing the problem

The lower control arm bushings replaced about seven years ago with greaseable fittings, everything under there has greaseable fittings. I cannot find the clunk.
