Help with Green bearings RP 400

DoctorDiff said
My axles are the same length as the originals.

Because MO-400 (snap-ring style) Green bearings move the axle OUTWARD slightly, the thrust buttons can remain intact.

Because RP-400 (crimped-on flange style) Green bearings move the axle INWARD slightly, the thrust buttons must be removed.

Here is your correct answer. Personally I take them out when using green bearings on DictatorDiff axles or Moser axles (these are the only axles I have used).
