[Hblick48]

I had a wet bolt that wouldn't take grease on right rear spring. By the time I got to look into it (was on 9,000 mile circle of America), here's what I found.

The wet bolt and the bronze bearing had fused together. The side of the brass bearing opposite from the hole in wet bolt had worn very thin. Because the two had fused, eventually the bolt with the knurled portion started to rotate, and wore the hole in the shackle. When I tried to install new wet bolt, hole was worn larger than the knurling, so the bolt wouldn't lock in.

Had to cut shackle from frame and weld in a new one.

I now make sure all bolts accept grease on a regular basis.
