Final drives

What is a final drive?

• A trip in a hearse.

• Distance from tee to fairway and green.

• A torque multiplier

• Allows wheels to turn.

Why is it necessary to fit a differential to a vehicle?

• To enable car to pull away when one wheel has no traction

• To enable wheels to rotate at different speeds

• To split power to rear wheels

• Propels the torque converter

What is the advantage of a limited slip differential?

• If one wheel loses traction, the other will still turn.

• It splits torque to each wheel individually

• It allows power to turn 90 degrees

• It uses more fuel

What is ring gear backlash?

• Play in the companion shaft

• Play in companion flange

• It is how much crown ring is warped

• It is rotational movement between crown ring and pinion

What is flank contact?

• Contact is at the bottom of the tooth.

• It is the movement in side gears

• It is how companion flange contacts pinion

• Contact is at the inner end of the tooth

What is toe contact?

• Contact is at the bottom of the tooth.

• Contact is at the inner end of the tooth.

• Excess play in pinion ring

• Excess play in companion crown
