TRAILER MAINTENANCE
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
Start all wheel lug nuts by hand.
1.
Torque all lug nuts in sequence (see Figure 57).
2.
DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defi ned
by Table 16.
After fi rst road use, retorque all lug nuts in sequence.
3.
Check all wheel lug nuts periodically.
