Final drives

Which component contains a crown wheel and pinion?

• Differential
• Final drive
• Steering box
• Transfer box

What is the main purpose of the final drive?

• To provide a gear reduction and multiply torque
• To allow the wheels to rotate at different speeds when cornering
• To transmit torque from the gearbox to the differential
• To make the wheels rotate faster when pulling away from stationary

The final drive in a RWD vehicle rotates the drive through an angle of?

• 180 degrees
• 45 degrees
• 90 degrees
• 270 degrees

Which numbered component in the RWD driveline/drivetrain diagram shown below is the final drive?

• Component number 3
• Component number 2
• Component number 5
• Component number 7
