Question
Technician A says that when diagnosing a rear axle, excessive gear wear can be caused by a low fluid level. Technician B says backlash is the clearance between the ring and pinion gear. Which technician is correct?
Solution
Technician A is correct in saying that excessive gear wear in a rear axle can be caused by a low fluid level. The fluid in the axle provides lubrication for the gears. If the fluid level is low, the gears may not be properly lubricated, leading to excessive wear.
Technician B is also correct. Backlash is indeed the clearance between the ring and pinion gear. It is a necessary part of any gear system to prevent the gears from binding and to allow for heat expansion when the gears are in operation.
So, both Technician A and Technician B are correct.
