Wheel Installation
It is extremely important to apply and maintain proper wheel
mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER
TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSI-
BLE DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. BE SURE
TO USE ONLY THE NUTS MATCHED TO THE CONE ANGLE OF THE
WHEEL.
Tighten the lug nuts to the proper torque to prevent wheels from
coming loose. Use a torque wrench to tighten the fasteners. If
you do not have a torque wrench, tighten the fasteners with a
lug wrench, then immediately have a service garage or dealer
tighten the lug nuts to the proper torque. Over-tightening will
result in breaking the studs or permanently deforming the
mounting stud holes in the wheels. The proper procedure for
attaching wheels is as follows:
1. Start all nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2. Tighten nuts in the following sequence:

3. The tightening of the nuts should be done in stages. Fol-
lowing the recommended sequence, tighten the nuts per
wheel torque chart.
