A driver complains of steering wheel 'Shimmy' that gets worse as the vehicle's speed increases, This most likely indicates
The tyre pressures are too high
The front wheels need balancing
The wheel wheel alignment needs adjusting
The shock absorbers need replacing
In relation to steering geometry 'Negative offset' is produced when the

Centre line through the swivel pin intersects the centre line of the wheel below ground level
Centre line through the swivel pin intersects the centre line of the wheel above ground level

Which of the following faults will change the camber angle?
Very high tyre pressures
Unbalanced front wheels
A buckled front wheel
Incorrect toe setting
ONE advantage of alloy road wheels compared to steel road wheels is they
Increase in unsprung weight
Reduce unsprung weight
Are cheap to manufacture
Reduce heat transfer
In relation to steering geometry, the purpose of the castor angle is to;
Allow for deflection of the wheels
Provide self centring of the steering
Provide toe out on turns when cornering
Provide centre point steering layout
In relation to steering geometry 'Camber angle' is defined as
The outward or inward tilt of the road wheel
The angle between the king pin and the wheel
The backward tilt of the kingpin or swivel pin
The inward tilt of the king pin or swivel pin
In a hydraulic power steering system the maximum pressure is limited by the
Hydraulic pump
Map sensor
Control Valve
Relief valve
After fitting component labelled 4 in the drum brake diagram below, What must you do?
Drive the vehicle
Check the springs
Check the adjustment
Bleed the brakes
Which of the following is a form of steering mechanism?
Ackermann steering
Peg and Ball
Crown wheel and pinnion
Rack and pinion
To satisfy the MOT regulations the minimum braking efficiency for the footbrake must not be;
Less than 16%
Less than 25%
Less than 50 %
Less than 75%
In relation to checking and adjusting the front wheel alignment which of the following is NOT true
Adjustments should be made equally to both Track Rod Ends
You should remove heavy loads from the boot
You should check the tyre pressures are correct
Buckled wheels will not affect the wheel alignmemnt
The ackermann steering angle produces
Toe out of the front wheels during cornering
Understeer of the front wheels during cornering
Oversteer of the front wheels during cornering
Centre point steering on the front wheels
The customer complains that their vehicles pulls to the left during braking. One possible cause of this fault is:
the front wheel alignment is incorrectly set with excessive toe-in
the brake servo has failed due to a collapsed induction manifold pipe
seized front brake calliper pistons on the offside of the vehicle
seized front brake calliper pistons on the nearside of the vehicle

In relation to vehicle behaviour during cornering 'Understeer' is when the;
Slip angles of the rear tyres are smaller than the slip angles of the front tyres
Slip angles of the front tyres are larger than the slip angles of the rear tyres
Slip angles of the front tyres are the same as the slip angles of the rear
Rear wheels of a vehicle are carrying much less load than the front wheels
