WARNING
If vehicle is new and has been driven
less than 3,000 mi (4,800 km), it is
not necessary to align wheels unless
abnormal handling is reported.
Always use an OSHA approved
tire inflation cage for inflation
purposes. Stand on one side of the
cage during inflation; never
directly in front. Keep hands out of
cage during inflation. Inflate
assembly to recommended
pressure using a clip-on air chuck.
Do not exceed 50 psi (345 kPa)
cold-inflation pressure. Failure to
follow these instructions may
result in serious injury or death.
Never inflate a wheel assembly
without having checked wheel
locknut torques to ensure the wheel
locknuts are tightened to
specifications. An assembly with
improperly tightened locknuts could
separate under pressure, resulting
in serious injury or death.
CAUTION
Tighten locknuts gradually to
avoid bent and broken studs, or
damage to wheel components will
result.
(2) Tighten locknuts to 85 lb-ft
(115 Nm) in sequence shown;
repeat torque sequence at 110 lb-ft
(149 Nm).
