Cab Mounts

[Robert Crandall]

4 or 5 years ago I started having trouble with the fan hitting the underside of the top cover piece over the radiator. This is on my 1978 C20. I bent it, and bent it some more, but the hitting continued. Eventually I found that the front rubber cab (fender) mounts no longer existed. I cannot find it now, but somewhere on this forum I found a recommendation for a replacement cab mount kit. I bought it, and replaced those two front mounts. That stopped the fan hitting the cover piece problem. After a few years I got all six mounts replaced. I reused what remained of the existing shims, but the doors ground on their latches. Most annoying that was. Today, after a few years of being annoyed at that grinding I had time to remove the bolts from the center two of the pattern of six mounts, the ones under the door hinges. I jacked until the doors no longer ground on the latches. The driver side took 1/4 inch of shim. The passenger side took 3/8 inch. It surprised me that they took that much shimming. But what a difference! The sound of doors closing without the metal to metal grinding is such a huge improvement. I like it! The adjustment was surprisingly easy. Jack until I like the sound of the doors closing, find the shim thickness needed, jack some more to get them in place, lower onto them, check, tighten, done.

Thanks to this forum for providing the information on the replacement cab bumper kit.
