WHEELS (Continued)
center caps for more information refer to Owner's
Manual.
The tires on both wheels must be completely raised
off the ground when tightening the lug nuts. This
will ensure correct wheel centering and maximum
wheel clamping.
A two piece flat face lug nut with right-hand
threads is used for retaining the wheels on the hubs
(Fig. 24).
The dual rear wheel lug nuts should be tightened
according to the following procedure:
• Place two drops of oil to the interface of the nut/
washer (Fig. 24) before installing on the wheel stud.
NOTE: Do not use more then two drops of oil on
the nut/washer, since the center caps attach in this
area.
• Tighten the wheel lug nuts in the numbered
sequential pattern until they are snug tight. Then
tighten lug nut to specified torque following same
number sequence, (Refer to 22 - TIRES/WHEELS/
WHEELS - SPECIFICATIONS).
• Tighten lug nuts in same numbered sequence a
second time to the specified torque. This will ensure
that the wheels are thoroughly mated.
