Low RPM growl/rattle

[Phatdonkey78]

I have a 2007 hatch automatic. I got new wheels and tires in July. The car was in bad shape when I got it. Lots of suspension parts were replaced to get the alignment right and all. The original wheels look like they were driven thru Falluja at 100 MPH with dings all over. It had newer tires on it but hit so many pot holes they were blistered all over.

So after new wheels and tires I started to notice a slight rattle kinda sound at low RPM. The sound happens in all gears (automatic) but only at low RPM. No idea what exact RPM. I would assume around 1200 to 1500. Over that it goes away. It doesn't do it in neutral or park. Only under load. Assuming it was a pulley I removed the serp belt and went just down the road. Completely quiet. It has been slowly getting worse since July.

Spinning the alternator pulley with the belt off makes a slight clicking sound and spins very freely (charging fine). No pulley slack or anything but a ticking when spinning it by hand. Didn't climb under to check the ac pulley or water pump pulley. I ordered a non ac belt and will throw it on Sunday to rule out the ac compressor.

Has anyone else had this issue or any ideas of what to try?
