Application Type
Hub-piloted Aluminum Wheels Coat the wheel pilot or hub pads with Freylube #3 lubricant (light
colored) or Chevron Zinc lube. Do not get lubricant on the face of
the wheel or the hub.

Frame Fastener Torque
Requirements
CAUTION
Incorrectly tightening the fasteners may
result in failure of the fastener or incor-
rect clamp loads. Fastener failure may
lead to frame failure. Failure to comply
may result in equipment or property
damage.
• Use a torque wrench for final
tightening of these fasteners.
Due to the coating on the
threads of these bolts, be aware
that if an impact gun is used to
tighten the fasteners, they may
over-torque and break.
• When torquing, the nut must ro-
tate slightly before achieving the
torque value. If the nut does not
rotate, the fastener is over-tor-
qued and should be replaced.
• To achieve correct clamp loads,
the frame fasteners must be tor-
qued with the nut. The intended
clamp load may not be achieved
if the nut is held and torque is
applied to the bolt.
Where Nylon lock-nuts are
indicated in the following tables,
• Use only ESNA Style Lock Nut,
with nylon insert.
• Lubricate nylon insert nut lightly
with SAE 20W or 30W oil.
• Tighten all frame fasteners with a
torque wrench.
NOTE
The following values are applicable to
fasteners on the FRAME and DO NOT
APPLY to u-bolts for the suspension.
