Off-Vehicle Balancing

Perform wheel balancing with an electronic off-vehicle balancer. The balancer is easy to use and gives both a static and a dynamic balance. Unlike on-vehicle balancing, the off-vehicle balancer does not correct for drum or rotor imbalance. This drawback is overcome by its accuracy (usually to within 1/8 ounce). Secure the wheel on the balancer with a cone through the back side of the center hole, not through the wheel bolt holes.

Wheel repairs that use welding, heating or peening are not approved.

1. Raise and suitably support the vehicle.
2. Remove the wheel. Refer to "WHEEL REMOVAL AND INSTALLATION :".
   WARNING: To avoid serious injury, do not stand over the tire when inflating, because the bead may break when it snaps over the safety hump. Do not exceed 275 kPa (40 psi) of air pressure in any tire if the beads are not seated. If 275 kPa (40 psi) of air pressure will not seat the beads, deflate the tire. Relubricate the beads. Reinflate the tire. Overinflation may cause the bead to break and cause serious injury.
3. Locate leaking areas by inflating the tire to 345 kPa (50 psi) and dipping the tire and wheel assembly into a water bath.
4. Mark the leak areas and remove the tire from the wheel.
5. Scuff the inside wheel surface at the leak area with 80-grit sandpaper. Clean the leak area with a general-purpose cleaner.
6. Apply a 3.3 mm (0.13 inch) thick layer of adhesive/sealant to the leak area. Allow it to dry for 12 hours.
7. Install the tire on the wheel. Inflate the tire to 345 kPa (50 psi) and check for leaks as in step  3.
8. Adjust the tire pressure to meet specifications. Refer to "TIRE SIZE AND PRESSURE SPECIFICATIONS :".
9. Balance the wheel. Refer to "TIRE AND WHEEL BALANCING :".
10. Install the wheel. Refer to "WHEEL REMOVAL AND INSTALLATION :".
11. Lower the vehicle.
