There is a pdf file, for Newmar Slides, with diagrams of bearing locations, , in the sticky posts at the top of the Newmar owners forums " Quick mods and Easy fixes" ? or is it Quick fixes and Easy Mods.
That's where I got my info, if your year slide mechanism is similar to mine , it looks like the drive shaft has to come out, from the diagram any way , I haven't looked at the coach.
