Installation

INSTALLATION PROCEDURE





CAUTION: Before installing the wheels, remove any buildup of corrosion on the wheel mounting surface and brake drum or disc mounting surface by scraping and wire brushing. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This can cause a wheel to come off when the vehicle is moving, causing loss of control and possibly personal injury.

NOTICE: A torque wrench or J 39544 must be used to ensure that wheel nuts are tightened to specification. Never use lubricants or penetrating fluids on wheel stud, nuts, or mounting surfaces, as this can raise the actual torque on the nut without a corresponding torque reading on the torque wrench. Wheel nuts, studs, and mounting surfaces must be clean and dry. Failure to follow these instructions could result in wheel, nut, and/or stud damage.

^ Tools Required:
- 0-300 Nm (0-200 ft. lbs.) Torque Wrench

1. For the 1500 Series (five stud), install the wheel and the tire assembly in position on the hub/rotor. Loosely install the wheel nuts.





2. For the 2500 Series (six stud), install the wheel and the tire assembly in position on the hub/rotor. Loosely install the wheel nuts.





3. For the 2500 Series (eight stud), install the wheel and the tire assembly in position on the hub/rotor. Loosely install the wheel nuts.





4. For the 3500 Series (eight stud, single wheel), install the wheel and the tire assembly in position on the hub/rotor. Loosely install the wheel nuts.





5. For the 3500 Series (dual wheels), install the wheel and the tire assembly in position on the hub/rotor. Loosely install the wheel nuts.





6. Turn the wheel until one nut is at the top of the bolt circle. Tighten the top nut securely, but do not tighten to specification.
7. Loosely tighten the remaining nuts in a criss/cross pattern in order to minimize runout.

Tighten
^ Tighten the nuts to 190 Nm (140 ft. lbs.).
^ Tighten the nuts evenly and alternately in order to avoid excessive runout.

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
