Is this a thrust button and can it be removed?

Have you seen Chris Birdsong’s video on green bearings?
He REALLY hates them.

Found it.


Yup, I agree with what he has to say except for his use of the term "preload". There is no preload on the tapered roller bearings in the rear axle. Front wheel bearings technically are supposed to have some, although I never load them myself beyond finger tight. There is however an end play adjustment on the rear axles. That is accomplished by the adjustment nut on the passenger side bearing retainer. With a dial indicator, a simple process. Even without one you can get it close enough to where you won't have a problem. This is all assuming you have stock drum brakes. Disc conversions have their own needs depending on design.
