my 07 expy makes a clunk of some sort when am straightening out of turns, i think for the most part, I have checked under, like struts, bushings, steering, etc and dont see anything obvious that sticks out....it sounds like a semi-metallic dampened clunk of some sorts, also with a squeal to it low pitch.... like something is snapping into place or something....any ideas?

 

2wd or 4wd?

 

2wd

 

I might be lower ball joints.

 

Well, it might be anything. Take it to a good front end shop and have it inspected if you can't find anything wrong.

 

Ball joints .You should check it when your car lifted and wheels don't touch the ground. It mustn't have a backlash
