Heavy Goods Vehicle Inspection: Axles, Stub Axles and Wheel Bearings Mobile App

mobile app is to support staff in conducting the annual testing of vehicles. The app is useful to those responsible for the maintenance of large commercial vehicles so that they remain well informed on the current minimum legal standards for roadworthiness. It must be emphasised that these are minimum acceptable standards, which do not necessarily allow for further deterioration when the vehicle is in service.

This inspection applies to the steered wheels of all vehicles and trailers. A steered axle is one which has a king pin or ball joints and can be turned to a left and right lock. An axle ceases being steered when it is fixed in the straight ahead position. When assessing excessive wear, play or lift account must be taken of any information given and/or manufacturers’ recommendations.
