Clicking clunking sounds while driving 99 Tahoe

My wife drives a 99 Chevy Tahoe 4x4. It clicks and clanks loud going down the road it's embarrassing. The sound is coming from underneath the truck. Doesn affect driving or anything but it sounds horrible. What could this be? I've check driveshafts, pinion joints, u joints. Everything is tight. I did notice the seal is bad in the front pinion. But it's still nice and tight. Could the front diff be making this noise? 4x4 still works like it should. You can feel the clunkin/clicking in the floor board under your feet

Maybe a broken stabilizer link?

Cats with loose honeycomb, rattles like crazy. Mine both do it on my '97 Tahoe, gonna take care of it when I add headers. I drilled small holes and put screws in 'em to try to hold the stuff in place, lasted a few miles before it started rattling again.

Re: Clicking clunking sounds while driving 99 Tahoe

check your sway bar mounts the ones on the frame. if they are worn you will get a rattler or clunking as you drive.

Re: Clicking clunking sounds while driving 99 Tahoe

Check the front stabilizer bar mounts on the frame and the control arms. When these break you don't always notice driveability issues. Here's a video on how to replace them (to show you the location to look).
