Wheel bolts
Fig. 190 Changing a wheel: Loosening the wheel bolts.
Wheel bolt tightening torque
Correctly tightened bolts for steel and alloy wheel rims should have a torque of 88 ft-lbs (120 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.
Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
WARNING
Improperly tightened wheel bolts can come loose while driving and cause you to lose control over the vehicle, resulting in accidents and serious injuries.
x Only use wheel bolts that belong your vehicle and to the wheel being installed.
x Never use different wheel bolts.
x Wheel bolts and wheel hub threads must always be clean, easy-to-turn and free of oil and grease.
x Only use the lug wrench that is supplied with the vehicle to loosen the wheel bolts.
x Loosen the wheel bolts only about 1 turn before lifting the vehicle with the jack.
x Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
x Never loosen bolted connections on wheel rims with bolted rim rings.
x If the wheel bolts are not tightened to the proper torque, the wheel can come off the vehi-cle when it is moving. Extremely high torque can damage the wheel bolts and/or their threads.
