2003 Chevy C5500. While changing the front shocks (25k miles on a set of Monroes and they were shot) I noticed the plactic fender liner on the front passenger side had rubbed through the wiring harness under the fuse boxes. I taped up the chafed wiring and installed a piece of plastic wire loom to prevent it happening again.
Installed Bilstein front shocks. They are allot stiffer and there is less body roll than I've ever had on that truck.
