Your end links might be shot you can't notice it till they come off..the end bolt will have hella play like a dam joy stick if they're shot

It could be the sway bars, but I've recently had to replace both front struts and one rear shock due to the noise. All three failed at less than 70k miles.

I got the same issue, but mine is usually when i enter a parking lot, especially when the slope is high. Been meaning to have it checked out.

Betcha a dollar that it's your sway bar bushings having rotted out. You should be able to crawl under and look to see if that's the case.
