I have a '99 Jimmy with a "clanging", for lack of a better word, coming from the front driver's side wheel. I only hear it when i hit a bump. It goes away when i push on the brake, and no braking issues that i can tell. Today i pulled the wheel off and checked the brake caliper and it seems to be on tight, no abnormal wear on the rotor. The only thing i noticed was the upper ball joint boot had a crack in it (i replaced these not long ago, along with new tie rod ends, probably overfilled it with grease). I also had the wheel bearing replaced three weeks ago. I haven't replaced the shocks yet, could it be a worn out shock? Any ideas anyone?

Could be any number of things... possibly a shock, or possibly one or both of the sway bar links has broken. Just have to get under there and start looking and wiggling things around.

Did you replace the hood washer? If not, check into that, there is a spring washer thread on this forum that explains it very well.

I had a clunk and clang also that I never heard until I replaced the ball joints, and hubs. Didn't sound like it was coming from the hood area, but it was. I had a driver door upper pin bushing broken also, so don't really know if the hood washer or the new door pins fixed the clunk but it is gone.

I swore this noise was coming from the wheel well area, it wasn't.

Can't find the hood washer thread.
