5. Inspect the bearing cups and cones for any rough surface conditions
and replace both cup and cone when necessary. Pitted and galled
rollers and/or bearing cap indicate replacement is necessary. Very
light marks around each roller may occur during "break-in period"
from the bearing cage. This is not a problem and bearing replacement
is not necessary.
