Preparation
Before carrying out this inspection, make sure that any mechanism for adjusting
the steering column is fully locked. Exert reasonable pressure only on the steering
wheel, particularly when the steering column is collapsible.
Access to some components
For a full inspection of some components you may need to examine them from
under-bonnet, underside or in the foot well area, using an inspection lamp and
an assistant to operate the steering where necessary.

1. Check the strength
and condition (including any modifications) of the steering wheel by applying
reasonable force.
2. Push the steering wheel rim in various directions at right angles to the column,
while applying light pressure downward and upward. Check for
a. insecurity of adjustable steering column
b. movement between column shaft and steering wheel
c. excessive play in top column bearing
d. insecurity at column top mounting bracket
3. Pull and push the steering wheel in line with the column. Check for any movement
at the centre of the steering wheel. Note: Certain types of steering column (e.g.
those fitted with universal joints or flexible couplings) may show some movement
which is not due to excessive wear or deterioration.
4. Turn the steering wheel clockwise and anti-clockwise, checking steering column
couplings and clamp bolts for security.
5. Check the presence and security of retaining and locking devices. Note: The
inspection is not concerned with the type of locking device, only its presence
and security.

1. Steering wheel
weakened by modification, cracks, fractures, in a condition that hampers proper
control or likely to injure the driver’s hands. Note: Cracks or incompleteness
of the covering skin of a steering wheel or hub, are not a reason for rejection.
2.
a. an adjustable steering column will not lock in a fixed position
b. movement between the shaft and steering wheel
c. excessive radial movement (play) at the top of the steering column between
the column and the shaft indicating a badly worn top bearing Note: Some vehicles
have flexible top bearings for the steering column. With these more than average
movement is acceptable
d. insecurity at the steering column top mounting bracket
3. Excessive steering shaft end float.
4. Insecurity, excessive play or deterioration of a flexible coupling or universal
joint.
5. A retaining or locking device missing or insecure
