Abstract:
A method for measuring at least one vehicle wheel alignment angle from a vehicle wheel hub assembly, comprising:mounting a wheel alignment sensor to a wheel rim and tire assembly secured to said vehicle wheel hub assembly; obtaining a first measurement of at least one alignment angle with said mounted wheel alignment sensor; removing said wheel alignment sensor from said wheel rim and tire assembly; removing said wheel rim and tire assembly from said vehicle wheel hub assembly; mounting said wheel alignment sensor to said vehicle wheel hub assembly; and obtaining a second measurement of said at least one alignment angle with said mounted wheel alignment sensor; calculating an offset angle using said first measurement and said second measurement, said offset angle representative of an angle variation between a wheel-mounted sensor angle measurement and a vehicle wheel hub assembly-mounted sensor angle measurement; and subtracting said calculated offset angle from at least one predetermined specification value for said at least one alignment angle to offset said specification value, wherein one or more subsequent vehicle wheel hub assembly-mounted sensor angle measurements of said at least one alignment angle may be compared with said offset specification value to determine a required wheel alignment adjustment.
