Default A Strange Clunk and weird vibration (2 separate issues??)

Need some help........I get a strange clunk (not all the time), but occasionally when I'm at low speeds (like 25mph) and then accelerate hard (well as hard as a 3.8 will allow...lol) and get this noticeable clunk. At first I thought it was my front driveshaft, but I recently replaced it with a Tom Woods shaft, and the same clunk is there. Any thoughts?

Also, a separate issue........at low RPM's (1000 for example).....I get this weird vibration that feels like I'm going over a rumble strip........it's only there if I am on the gas pedal.....as soon as I let off or speed up to higher RPM's it goes away.

Could the 2 issues be related? Maybe some chipped teeth in my gears???

Any help is greatly appreciated.

i've recently added lower front adjustable control arms and had the pinion angle corrected, and the u-joints are all brand new with the new front driveshaft, so I don't think those are the issues.

Was the issue there before the new control arms and pinion angle adjustment? What's your pinion set at now?
