Stationary Gear Bearings...replace both?

[Ender]

'usable' is subjective, and if you go by the FSM for wear specs you will most likely be disappointed. don't skip out on your bearings, IIRC they're not terribly expensive to do anyway. make sure if you're not doing them yourself though you have a machinist do it. I took mine to an auto shop and they fucked up my bearings that I didn't actually need to replace, so then I had to replace them. had a machinist do it, he found a piece of drive shaft that fit perfect and he got the job done beautifully despite the kludge lol
