Default New clunk

In the last few days, I've noticed a new clunk. Sometimes when I put it in gear, sometimes when I hit a bump, sometimes for no appearant reason at all, just moving. Definatly in the front, seems like it'* coming from the passenger side. I was under it last Saturday and checked out my motor mounts like I always do while I'm down there, they seemed fine. Struts were replaced all around last Fall.

Any thoughts?

Have an assistant watch the motor when you move the selector from D to R and back. Visually inpecting a motor mount is good, however you can not always see a bad mount.

Check CV boots etc for signs of an axle going.

COULD be an upper strut bearing. That'* very hard to diagnose. Is it worse when it'* cold?

Could be, they were replaced with Monroe uppers when I had the struts done. I'll pop the tower cap off and give it a good shot of WD-40. I haven't noticed any difference cold or hot.
