Information
Method of Inspection
Reason for rejection
How to inspect
The checks in this sub-section must be
carried out
. with the vehicle over a pit or on a raised lift, and

. the rear of the vehicle jacked up so that ideally the suspension hangs freely with both wheels clear of the ground.

Other testable items may be more easily examined while the vehicle is Jacked, particularly when the rear suspension is hanging freely.

Reason for rejection I does not apply to a vehicle where it is not possible to rotate the wheel due to a design characteristic or its drive configuration.
1. Rotate each wheel in turn and listen for. any sound indicating roughness in the bearing,
2. Rock each wheel by hand or when appropriate With a bar in the wheel, and check the movement of the wheel relative to the axle to assess the amount of play in the wheel bearings.

Note: It may be an advantage to use an assistant when carrying out this check.

1. Excessive roughness in a near wheel bearing.

2. Excessive play in a rear wheel bearing, indicating severe maladjustment or wear.
