"Clunk" in Front End

2007 Cobalt Coupe 5 Speed with 74k miles.

When I drive over a fairly rough surface or bumps I hear a pretty solid "clunk" coming from the front end, it's most noticeable on the front left.

Any ideas what this might be?

Probably your strut worn out. Does it do that at all speeds?

Sounds like strut. If it happens when you're accelerating or decelerating, it could be CV joint.

strut mount or strut. might as well spend the money and get both, and get the pair of each.

It's not the ratchet sound you get when turning that indicates bad CV joints.

The rebound seems fine (not bouncing and wallowing, pushing down on the fender it returns and settles immediately), seems like the struts are doing their job.

Only happens when you hit a bump, on the initial hit you hear a pretty solid "clunk".

I'll check on the lower A Arm bushings!

All good responses, also check your swaybar. I've had the bushings on the swaybar connecting rods go bad.

Start with the simple and cheap stuff first. If I had to guess I would say you need new sway bar bushings. They are cheap and take about a hour to do in your own driveway at a liesurely pace. The bushing doesn't wear around the bar itself but wihtin the bracket and that makes a pretty good clunking sound.

Do not adjust your set - temporary difficulties are only technical
