LV13

A rear wheel drive final drive assembly is noisy on vehicle overrun.  

Which one of the following is the most likely fault? 

 

• Worn half shaft bearings 

• Broken half shaft 

• Crown wheel and pinion teeth worn 

• Worn differential gears 

 

One cause of clutch drag is:

•  

   Fatigued diaphragm spring 

• Seized clutch release bearing 

• Minimal free play at the clutch pedal

• Contaminated clutch plate

A front wheel drive manual transmission has vibration at all vehicle speeds.  

The most likely fault is: 

 

• Dry CV joint

• Worn layshaft bearing 

• Bent drive shaft 

• All of the answers shown  

A manual transmission jumps out of gear.  

One possible cause is: 

• Weak interlock mechanism 

• Worn selector forks 

• Worn synchromesh baulk ring 

• All of the answers shown 

A front wheel drive vehicle fitted with a manual gearbox has difficulty in engaging gear.  

Which one of the following is the most likely cause? 

• Release bearing seized 

• Contaminated clutch linings 

• Broken clutch centre plate springs 

• Maladjustment of remote mechanism 

Which one of the following statements is FALSE?  

  

• Rapid knocking noise when cornering is a defective CV joint 

• A viscous coupling can be used as the third differential in a 4WD system

• The final drive turns the drive through a right angle on front wheel drive vehicles

• The final drive ratio increases the torque to the road wheels and reduces speed 

A vehicle with a manual transmission will not disengage the clutch.  

One possible cause is: 

Broken centre plate torsional springs

 Worn pressure plate 

Centre plate sticking on gearbox input shaft splines 

Contaminated clutch linings 

• Broken centre plate torsional springs

• Worn pressure plate 

• Centre plate sticking on gearbox input shaft splines 

• Contaminated clutch linings 

When a traction control system senses wheel slip it will:  

• Reduce the engine RPM and brake both wheels 

• Stop the ABS modulator working 

• Limit the engine RPM and brake the slipping wheel 

• Automatically brake the parallel driving wheel 

 

One advantage of using electronic transmission control is?  

• Improved fuel economy 

• There is no requirement for a hydraulic governor 

• A self-diagnosis facility can be built in 

• All of the answers shown

The signal to the solenoid valves in an electronic transmission system is sent from:  

• Speed sensor 

• ECU 

• Pattern select switch 

• Throttle position sensor
