Hey Guys, '03 Suburban, new Munroe OESpectrum shocks all around. There is a squeak and clunk in the rear suspension that the mechanic can't figure out. The issue is that going in/out of driveways, rough roads, speed bumps, there is a metal on metal rubbing sound, like bad bushings and sloppy leaf springs. and a clunk/clank like leaf spring slap. The thing is, the Burb doesn't have leaf springs and there are no signs of loose or wear in the suspension components. The mechanic had the thing for two days and couldn't figure it out. I went back in and went on a test drive with them and couldn't get the clunk/clank, but was able to replicate the squeak/rubbing sound. They still couldn't find anything. It occurred to me after the test drive that the Burb normally carries around 300 to 400 pounds in the cargo area, so I put the weight back in when I got the truck back and the clunk is back. So, it's obviously weight related, but that doesn't explain why there are no wear indicators. The mechanic said they can't see anything and can't get anything to move when it's up on the lift. The mechanic has checked the shock attachment points, trailing arms, spring cups, etc., to no avail. With the amount of noise this thing makes, there should be something obvious, but it's hiding!! Any thoughts?
