Rear Halfshaft Notes:

NOTICE: Never pick up or hold the halfshaft by only the inner or outer Constant Velocity (CV) joint. Damage to the CV joint will occur.
NOTICE: Never use a hammer to remove or install the halfshafts. Damage to the CV joint may occur.
NOTICE: Never use the halfshaft assembly as a lever to position other components. Damage to the halfshaft or CV joint may occur.
NOTICE: Do not allow the boots to contact sharp edges or hot exhaust components. Damage to the halfshaft boots will occur.
NOTICE: Do not drop assembled halfshafts. The impact may cut the boots from the inside without evidence of external damage.
STEP 11: Be sure to clean area around halfshaft of any dirt and debris prior to removal of the halfshaft to prevent any debris from contaminating parts. Then, using a pry bar, remove the halfshaft.

WARNING: When a wheel is installed, always remove any corrosion, dirt or foreign material present on the mounting surface of the wheel and the mounting surface of the wheel hub, brake drum or brake disc. Make sure that any fasteners that attach the rotor to the hub are secured so they do not interfere with the mounting surfaces of the wheel. Failure to follow these instructions when installing wheels may result in the wheel nuts loosening and the wheel coming off while the vehicle is in motion, which could result in loss of control,leading to serious injury or death to vehicle occupant(s).
NOTE: Make sure to apply a thin coat of anti-seize lubricant only to the interface between the wheel pilot bore and the hub pilot. Do not allow the anti-seize to make contact with the wheel-to-brake disc/drum mounting surface, wheel studs, wheel nuts, brake pads or brake disc friction surfaces or damage to components may occur.
WARNING: Retighten wheel nuts within 160 km (100 mi) after a wheel is reinstalled. Wheels can loosen after initial tightening. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
NOTE: Failure to tighten the wheel nuts in a star/cross pattern can result in high brake disc runout, which accelerates the development of brake roughness, shudder and vibration.
NOTE: The wheel nut torque specification is for clean, dry wheel stud and wheel nut threads.
NOTE: Final tightening to be performed with vehicle resting on tires.
STEP 23: Clean the mounting surface of the wheel. Apply the substance from the specified tube.
Material: High Temperature Nickel Anti-Seize Lubricant / XL-2Ford
