When examining the inner & rollers/cone I look for wear, scoring, smearing,
heat discoloration or any other sign I can find that the bearing has been
harmed. If I do find this then I assume the outer ring/ the cup also needs
to be replaced and, as this is pressed into the hub, it may be a trick for
you to remove....but it should be done or you are wasting the effort...IMHO.
There are or were emergency bearing kits available for boaters. You supplied
the part number and the kit came with 2 Cups, 2 Cones, a dab of bearing
grease and a handy-wipe to clean your hands.
If you don't want to go thru all of this you should be able to find the name
of the trailer mfgr on the trailer and if you call them they will be able to
give you the bearing part numbers for the set you need ( the bearing part
numbers follow a generic system ...but not all brands are of the same quality
so...... )
..... good on you to plan ahead for an emergency. I have helped people out
on the road and notice that bearings never fail where it is easy to find the
right replacement set....weekends, nights or deep in the pucker brush.
