Driving on the smooth road there are no issues and it handles great, just the noises when on bumps. I suspect possibly the 160k+ mile factory control arm bushings are worn and slopping around? Any advice would be great before I start throwing money at parts. Thanks!
If the control arms have never been serviced that is 100% a problem if not the problem.
Other things it could be are motor mounts and transmission mounts. They should be replaced at the same time.
Swaybar endlinks like to clunk when they go bad. The sway bar bushings should be looked at too.
Your battery isn't bouncing around in there is it?
Here are mine at 127. The center isn't even attached. Just sitting in there. My motor mounts were that bad or worse too. Especially on the drivers side.
