I don't think that's the problem, Dale. The axial thrust is - or could be.
While Duane is right that no standard ball bearings are designed to take up
large axial forces (almost a definition of "standard") thrust bearings are.
Scott has tested the mounting of the bearing in the bracket and found that
with the screws according to the AD it takes 800 lb of axial thrust to
break the rim of the bearing. However, to my knowledge, the braking point
of the bearing itself has not been tested under axial load. It may break
long before reaching 800lb or it may not. We just don't know. (It hasn't
given way in my case).
