Steering affected. X
Item Method Reasons for failure Assessment of deficiencies
Minor Major Dangerous
(g) Cables/hoses damaged, excessively corroded.
X
Steering affected. X
2.2. Steering wheel, column and handle bar U.K.
2.2.1. Steering wheel/handle bar condition
With the vehicle over a pit or on a hoist and the mass of the vehicle on the ground, push and pull the steering wheel in line with column, push steering wheel/handle bar in various directions at right angles to the column/forks. Visual inspection of play, and condition of flexible couplings or universal joints.
(a) Relative movement between steering wheel and column indicating looseness.
X
Very serious risk of unlinking. X
(b) Absence of retaining device on steering wheel hub.
X
Very serious risk of unlinking. X

Very serious risk of unlinking. X
2.2.2. Steering column/yokes and forks and steering dampers
With the vehicle over a pit or on a hoist and the mass of the vehicle on the ground, push and pull the steering wheel in line with column, push steering wheel/ handle bar in various directions at right angles to the column/forks. Visual inspection of play, and condition of flexible couplings or universal joints.
(a) Excessive movement of centre of steering wheel up or down.
X
(b) Excessive movement of top of column radially from axis of column.
X
(c) Deteriorated flexible coupling.
X
(d) Attachment defective.
X
Very serious risk of unlinking. X

X
Item Method Reasons for failure Assessment of deficiencies
Minor Major Dangerous
2.3. Steering play
With the vehicle over a pit or on a hoist, the mass of the vehicle on the road wheels, the engine, if possible, running for vehicles with power steering and with the road wheels in the straight-ahead position, lightly turn the steering wheel clockwise and anti-clockwise as far as possible without moving the road wheels. Visual inspection of free movement. Free play in steering excessive (for example, movement of a point on the rim exceeding one fifth of the diameter of the steering wheel or not in accordance with the requirements 1 . X
