Front End Rattle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a nasty rattling when I take on a bump... seems to be coming from the front driver wheel, or the underside of the front end suspension. Visually everything looks OK,... any ideas what problem could be hiding?

Brake pads can rattle . Try the same bumps with a light pressure on the brake pedal . If it is still there , check the shock mounts and the swaybar bushings if you have one . Just a couple thoughts .

what you need to do is jack up the front of the truck and do a front end check.. have a friend wiggle it back and forth with one wheel up in the air and see if you have play... take a large bar and stick it under the wheel and wiggle it to see if the ball joints have play.. same with the control arms
parts are cheap enough it wont take alot of $$$ to fit it

I hate to add this but I will. How does it steer? Check for broken metal where the steering box bolts up and check the radiator support mounts. jim

Radiator support mounts are good... just put in a new radiator.

I took a good look underneath, and nothing looks broken or out of place.

Could it be a broken coil spring? It's not leaning of sagging, but though that might be the case (and a good excuse to get some drop springs!)

It does steer good too... all the linkage checks out ok.

Did you check the ball joints and tie rod ends?

The previous owner replaced the lower ball joints, but not the uppers for w/e reason. They could be suspect...

Hey
check your front shocks. I had one come loose where it bolts to the
frame and it drove me crazy tll I figured it out rattled like mad

tightened it up and no problem since

good luck
Mark

Frank, I think that was it... it does not rattle when I"m on the brakes over the bumps.

So you think its the brake pads themselves? Or a loose caliper?
