Which preparation is required before measuring wheel alignment?

  • A.A full fuel tank only, which ensures that the vehicle sits at the attitude assumed by the specification data
  • B.A road test
  • C.Removal of the wheel trims, which would otherwise prevent the measuring heads from being attached to the wheel rims
  • D.A level surface, correct tyre pressures and correct ride height

Answer: D

Alignment angles change with ride height, so pressures, load and suspension condition are all checked and the vehicle is rolled and bounced to settle it. Measuring on an uneven floor produces meaningless numbers. The preparation matters as much as the measurement. The shared behaviour explains why these belong together and the differences explain why both exist. The order in which the effects act is what decides the outcome, so it is worth establishing first.
