Transmission and Driveline

To allow the outer wheel to rotate faster than the inner one the transmission is fitted with?

• A free wheel mechanism

• A crown and pinion

• Differential

• A larger size of tyre at the rear

To prevent two gears engaging at the same time the gearbox is fitted with?

• Gear lever extension cable

• Interlock mechanism

• Synchromesh hub

• Dog clutch

Which of the following faults will it affect the way the car drives:

• Noisy thrust bearing

• Blown exhaust joint

• Low clutch fluid

• Clutch slipping

Which method is used to check the condition of a constant velocity joint?

• Repeatedly engage and disengage the clutch

• Drive the vehicle turning on both full left hand and right hand locks

• Drive the vehicle at a constant speed on a straight road

• Change down through all the gears

A constant velocity joint is used;

• In a fully floating axle

• In a rigid axle

• In a dead axle

• In a front wheel drive shaft

In a four-speed constant mesh gearbox the gears on the output shaft are always;

• Integral with the output shaft

• Splined to the output shaft

• Straight cut gear teeth

• Free to rotate on the output shaft

The gears used in a constant mesh gearbox are called;

• Helical gears

• Epicyclic gears

• Hypoid gears

• Spur gears

A worn rear wheel bearing is likely to make;

• No noise

• Humming noise

• Knocking exhaust

• A knocking noise

Misaligned propshaft universal joints on a rear wheel car can cause:

• The clutch to judder

• The transmission to whine at very high speeds

• The transmission to vibrate

• The clutch to wear excessively

A “live” rear axle arrangement:

• Adjusts to road conditions

• Is only fitted at the front of a vehicle

• Combines gearbox and final drive components

• Combines the differential and final drive in a rigid casing
