Re wheel bearings in Matco wheels.
The oil seals are bonded to the inner bearing race, and because there is
more friction between the wheel and the seal than between the race and
the axle the race turns on the axle.
We have PN 4798 spacer in stock (.0875 X .049 X 1.365) installing this
will provide adequate bearing preload and prevent the races from
turning.
