Important information regarding wheel bolts
The design of rims and wheel bolts is matched to the factory-installed wheels. If different wheels are
installed, wheel bolts with the right length and bolt head shape must be used. The attachment of the
wheels and function of the brake system depend on this.
It may not be possible to use wheel bolts from different vehicles of the same model.
Wheel bolt tightening torque
Correctly tightened bolts for steel and alloy wheel rims should have a torque of
103 ft lbs (140 Nm)
.
After changing a wheel, have the wheel bolt tightening torque checked right away with an accurate
torque wrench.
Before you check
the tightening torque, replace corroded and difficult-to-turn wheel bolts and clean
the threads in the wheel hub.
