Stories

Story 1:

A mechanic was working on a car when he heard a loud noise coming from the drivetrain. He opened up the transmission and found that the drive bearings were completely destroyed. The mechanic was shocked, because the car had only been driven for 50,000 miles.

Upon further investigation, the mechanic discovered that the drive bearings had not been properly lubricated. The lack of lubrication caused the bearings to overheat and fail prematurely.

The mechanic replaced the drive bearings and properly lubricated them. The car has been running smoothly ever since.

Lesson learned: Drive bearings must be properly lubricated in order to operate properly.

Story 2:

A woman was driving her car when she suddenly felt a vibration in the steering wheel. She pulled over to the side of the road and called a mechanic.

The mechanic arrived and diagnosed the problem as a bad drive bearing. The mechanic replaced the drive bearing and the vibration went away.

The woman was relieved that the problem had been fixed, but she was also curious about what had caused the drive bearing to fail.
