Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque. Be sure to use only the fasteners matched
to the cone angle of the wheel. Proper procedure for attach-
ment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 35. DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 10.
