alright sweet, roller bearings. The top one has like the spidercage thing.roller bearing, yes.
Wanna know how I know you are working on a large bearing case/shafts?
A surgeon wears thin gloves, I only wear leather gloves when removing the CS nut. There are things you have to feel without gloves on the sliders and hubs. Or you can just suggest replacing it all when some parts can be saved. Depends on the teams budget and communication.And the hands of a surgeon. And a bench big enough to keep stacks of parts from getting mixed up...
