Check the top of your struts. Make sure it doesn't look like this

Yikes! I removed one of the struts while replacing the UCA and nothing stood out but I’ll double check the top mounts.

I’m curious what that relay in the pic is for. Is that a NNBS?

Not sure. Not my ride

The folks who have replied know WAY more than I do. But when my 2001 Yukon had the clunking and bumping we finally figured out the exhaust was resting on the frame crossmember. Clever mechanic was able to fix after muffler shop weld failed. No problems since.
Easy to see anyway. Good Luck

A new steering shaft resolved this on my 2002 Yukon. It had seized up where it telescopes and I could feel everything in the steering wheel.

I had similar noises,hard over the bumps. Replaced the strut and problem was solved. Make sure they are properly installed and tightened.

I had control arm bushings go bad and then replacement MOOGs do the same about 15 months later. They could be sighted by backing slowly and braking while someone watched' movement was obvious.
