I have a 2007 Trek Fuel EX8 and decided to do the fork service on my own for the first time. The fork is a Fox Float 130 RL. The Fox guide says: "The anodizing on the upper tubes should be examined. If the anodizing has worn off due to lack of service, replacement of the upper tube assembly is recommended." When inspecting the stanchion tubes, it looks like there is wear on the Spring side. The anodizing has worn off, and I can feel slight grooves in that one section. I'm assuming the section is just about where the dust seals rest when the shock is unsprung, and the grooves go for maybe 2.5 inches. Should I ignore and re-assemble? The worst that could happen is that oil could leak out, right? Can I buy a replacement steerer tube? How much do those cost?
