  1. Remove the center cap by placing the chisel end of the wheel wrench in the slot on the wheel and gently prying the cap out.
  2. If the wheel has bolt-on wheel covers, loosen the plastic nut caps by turning the wheel wrench in a counterclockwise direction. If needed, finish loosening them by hand. The nut caps will not come off. Using the flat end of the wheel wrench, pry along the edge of the cover until it comes off.

    Caution: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

    Caution: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

  3. Position the jack under the vehicle as shown.
  4. Front Position

  5. Front Tire Flat: If the flat tire is on a front tire of the vehicle, you will need to use the jack handle (C) and only one jack handle extension (D). Attach the wheel wrench to the jack handle extension. Attach the jack handle to the jack. Position the jack on the frame behind the flat tire where the frame sections overlap. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to clear the ground.

Attach the wheel wrench to the jack handle extensions. Attach the jack handle to the jack. Use the jacking pad provided on the rear axle. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to clear the ground.

    Remove all the wheel nuts and take off the flat tire.

    Caution: Rust or dirt on a wheel or other parts to which it is fastened, can make the wheel nuts become loose and eventually the wheel could come off and cause a crash. Always remove all rust and dirt from wheels and other parts.


    Object Number: 811105  Size: A2

    Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

    Caution: Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash.

    Put the wheel nuts back on with the rounded end of the nuts toward the wheel after mounting the spare.

  9. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the nuts until the wheel is held against the hub.
  10. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
  11. Caution: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications for wheel nut torque specification.

    Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications for the wheel nut torque specification.

  12. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise.

When you reinstall the regular wheel and tire, you must also reinstall the either the center cap, or bolt-on hub cap, depending on what your vehicle is equipped with. For center caps, place the cap on the wheel and tap it into place until it seats flush with the wheel. The cap only goes on one way. Be sure to line up the tab on the center cap with the indentation on the wheel. For bolt-on hub caps, align the plastic nut caps with the wheel nuts and then tighten by hand. Then use the wheel wrench to tighten.
