Introduction
The following things should be checked
before wheel and axle measurements are
taken:
• Tire pressure
• Tires (are the correct tires mounted or are
different types of tires mounted on the same
axle).
• Bearing play
• Unnecessary play in kingpins, steering
gear, and the balancing arms support on
support axle vehicles.
• The attachment of the axles (play in
spring-eye bolts, shackles, broken center
rivets, broken springs and loose spring
straps).
• Worn torsion bar bushings
If any of the above mentioned points are not
correct, these should be fixed before procee-
ding with the measurements.
