Q: How do I know when bearing cup 4253226 needs replacement?
A: Replace the bearing cup if you notice grinding noise, excessive play in the jack handle, or visible scoring or pitting on the internal race. These symptoms indicate worn races that will cause premature failure of the mating bearing balls or rollers.
