Tightening torque for wheel bolts
Specified tightening torque for wheel bolts for steel or alloy wheels:
—140 Nm (103 ft-lbs).
If the wheel bolts are corroded and difficult to turn, they must be replaced and the wheel hub threads cleanedbefore
the tightening torque is checked.
Never grease or lubricate the wheel bolts or the threads of the wheel hub.
The tightening torque should be checked with a properly functioning torque wrench immediately after changing a
wheel.
WARNING
Incorrectly tightened wheel bolts can loosen while the vehicle is in motion and cause accidents, serious injury, and
loss of control of the vehicle.
● The wheel bolts and threads of the wheel hubs must be clean, free from oil and grease, and turn easily.
● Always use the box spanner placed in the vehicle at the factory to loosen and tighten the wheel bolts.
● Only loosen the wheel bolts by approximately one turn before raising the vehicle with the vehicle jack.
● Never grease or lubricate the wheel bolts or the threads of the wheel hub. This could cause them to loosen while
the vehicle is in motion, even if the required torque setting is used.
● Never remove the bolts on rims with bolted-on rings.
● If the tightening torque of the wheel bolts is too low, the wheel bolts and rims can loosen while the vehicle is in
motion. The wheel bolts and the threads could be damaged if the tightening torque is too high. Check the
tightening torque regularly using a torque wrench.
WARNING
The wrong wheel bolts can loosen while the vehicle is in motion and cause accidents, serious injury, and loss of
control of the vehicle.
● Only use wheel bolts that belong to the wheel.
● Never use different wheel bolts.
● On vehicles with two-piece wheel bolts: use only two-piece wheel bolts.
