Ok, I've had this ongoing problem with my truck! I need your help!!! It's been in the shop four
times for it and my service guy is BAFFLED! (along with me!) He's a pretty decent mechanic and I
have faith in his ability... Just a weird problem. It's a metallic rattle, related to hitting
bumps. It's low speed (can't hear it above about 35 or so.) Sounds almost like a washer behind a
loose nut would sound. If I pass over a bump I don't get any rattle when the front tires hit but
when the rear hits it goes. Here's what's been tried so far... Bushings installed between the leaf
springs, spring clamps tightened (stock), spring clamps replaced, every tightenable (and reasonably
easily accessed) nut and bolt on the underside of the truck has been checked and tightened, and the
body mounts have been tightened. Here's where it gets weird... Remember I said it rattles when the
rear tires pass over uneven pavement? Today we hooked up a spider mic, basically four mics attached
to the frame at each corner of the truck, and took a listen while driving. The ONLY mic that picked
up the rattle was the one in the right front corner! How's THAT for a gremlin! Has anybody had
this problem? Does anybody have a clue what this could be? We've called the "star" line, and two
other dealers, one of which had a similar problem before. There fix was tightening the body
mounts... which didn't work for me! (oh, we've pounded away with a rubber mallet at every
conceivable surface underneath the truck too!)
Thanks a mil for your inputs!!!
