When driving down a bumpy road I notice a clank over consecutive bumps in a row if I'm coasting. Almost no clank if I'm on the brake. Anyone else get this issue and if so what is it?

i have new lower control arms. new fe3 struts and bushings. i have new front brakes. and i have this rattle from the passenger side front wheel. i could swear it sounds like the caliper is rattling around. if i lightly hold the brake... the rattle goes away. its only over small bumps and road imperfections. I 'm going to the buy a big rubber mallet and a big plastic mallet and see if i cant find it when on jackstands.

FWIW, I had a loose caliper bracket replaced under warranty. It would rattle when going over highway control joints and garage entrances with the 1" raised concrete edge.

Really sorry to hear about the clanking sounds madm80mad. Have you considered taking the vehicle into a certified GM dealer for a diagnosis? I'd be more than happy to schedule a visit for you. Feel free to drop in a private message to me if I may be of assistance!

I appreciate that sir. I may have to be in touch with you in the near future. The car isn't being driven much but I would like to vet the problem solved before it becomes a serious issue.

As far as the suspension goes is it stock or has it been modified? If it has been modified what aftermarket parts do you have installed?

Pads are probably loose in the bracket. They shouldn't be so tight that they can't move (for obvious reasons) but if there's too much clearance between the pad and clip, they'll rattle like a sumbitch.

Things to check

1. Radius Arms (The forward most arm) Ball Joints. (With the suspension hanging, move the tire front to rear)
2. Radius Arm Bushing/Bolt issue
3. Caliper Bracket/pads loose or missing hardware.
4. Check the outer tie rods.
