Just as the title says, I removed the journals to replace the traction rubbers and the arms crumbled into about 5 small pieces. At first I thought, plastic rot. No, these are made of diecast. I was able to order a replacement truck (Lionel has been out of journals for 7 years) to get the 2 that I needed. The others were OK.
Anyone else have this happen to them? Just FYI.
By the way, the C-Clips removal and installation are a blast!
