What are the signs of a failing thrust bearing?
Common symptoms of a worn or damaged thrust bearing include a noticeable grinding, rumbling, or whining noise from the lower unit, especially when in gear. You might also detect excessive vibration during operation or find metal shavings in the gear lube during a change.

There is no fixed service interval for a thrust bearing.
