Installation
| Caution: Before installing
wheels, remove any build up of corrosion on the wheel mounting surface by
scraping and wire brushing. Installing wheels without good metal to metal
contact at the mounting surfaces can cause wheel bolts or nuts to loosen,
which can later allow a wheel bolt or nut to come off while the vehicle
is moving. Wheel bolts or nuts must be tightened in sequence and to proper
torque to avoid bending the wheel, brake drum or rotor. |
| Caution: Improperly tightened
wheel bolts or nuts can lead to brake pulsation and rotor damage. In order
to avoid expensive brake repairs, evenly tighten the wheel bolts or nuts
to the proper torque specification. |
| 1. |
Install tire and wheel assembly. |
| 2. |
Hand install lug nuts. |
| 3. |
Torque lug nuts in sequence,
as illustrated in Fig. 1, to 100 ft. lbs. |
| 4. |
Install wheel center cap, if equipped. |
| 5. |
Install wheel cap nuts, if equipped. |
