Step by step explanation on how an automotive differential works. This information
pertains to all vehicles.
Step 1 - An automotive differential is used to
evenly distribute engine power to the drive wheels. These differentials exist in
every vehicle which drive either front or rear wheels. Some vehicles utilizes front
and rear wheel drive commonly known as four wheel drive. This is achieved through
the use of a
transfer case, which separates engine power into two drive shafts.
Step 13 - A differential is designed to maintain
a level of gear oil lubricant, this check is done by removing the fill plug.
Gear Oil Level and Pinion Yoke Helpful Information
A differential is connected to the transmission, which is driven by the engine.
A driveshaft connects the transmission to the differential which is responsible
for determining the number of rotations the axles will turn in relation to the driveshaft.
Gear ratio's are used to multiply engine torque delivered to the drive wheels. Ring
and pinion gears are helical cut for smooth operation.
Differential gear oil level should be
checked and serviced
according the manufacturers recommendations. Inspect fluid consistency along with
contaminants, which could be a sign of bearing or gear operation failure. Any abnormal
noises should be addressed before permanent damage occurs.
