SERVICE AND MAINTENANCE
WARNING
• If you find any abnormal conditions with the wheel nuts such as frequent
loosening of retightened nuts, have your vehicle checked or serviced at the
nearest Isuzu Dealer as soon as possible.
CAUTION
• Fully engage the wheel bolt wrench on a wheel nut to be able to tighten the
nut to the specified torque. However, do not use a pipe as a handle extension
or your foot to apply force on the wrench. This would tighten the nut more than
required and might damage components.
• Both under-tightening and over-tightening of wheel nuts may cause broken
wheel bolts or a cracked disc wheel and would lead to wheel detachment.
Adhere to the specified tightening torques.
• When replacing a tyre with a new one, use only a tyre of the same type and size
as the replaced tyre; otherwise, driving safety would be affected. Avoid mixing
different type and different size tyres at all costs.
3. Tighten the previously loosened outer
wheel nuts to the specified torque. (Do
not loosen the other wheel nuts.)
Wheel nut tightening torque
550 - 600 N·m
(55 - 60 kgf·m/398 - 434 lb·ft) (wet)
ADVICE
• Apply a thin coat of engine oil, gear
oil or power steering fluid to the
threads of the outer wheel bolts.
4. Perform the second sequence of the
procedure for the remaining half of
the bolts according to Steps 1 to 3,
first tightening the inner wheel nuts
and then the outer wheel nuts.
