The best method of fixing a winch motor bearing of the sealed type that is running hot is to _______________.

Aapply a light oil to the bearing housing
Breplace the bearing with a new one
Callow the winch to run at slower speeds only
Dadd grease through the Zerk fitting
AI Explanation

The correct answer is B) replace the bearing with a new one. When a sealed winch motor bearing is running hot, it typically indicates that the bearing is worn and needs to be replaced. Applying oil (option A) or running the winch at slower speeds (option C) may provide temporary relief, but they do not address the underlying issue of the worn bearing. Additionally, adding grease through a Zerk fitting (option D) is not the appropriate solution for a sealed bearing, as the bearing is not designed to be re-greased. The best course of action is to replace the bearing with a new one, as this will restore the proper functioning of the winch motor and prevent further damage or potential failure.
