4. Apply a liberal quantity of anti-seize compound to the splines of the front drive shaft.
5. Insert the two rearmost, top and bottom rotor hub bolts in the steering knuckle. Insert the bolts through the back side of the knuckle so they extend out the front face as shown.
6. Position the hub spacer and brake shield on bolts just installed in knuckle.
NOTE: If the vehicle is equipped with a wheel speed sensor the brake shield must be positioned on the hub bearing.
7. Align the rotor hub with the drive shaft and start the shaft into the rotor hub splines.
NOTE: Position wheel speed sensor wire at the top of the knuckle if equipped.
8. Align the bolt holes in the hub bearing flange with the bolts installed in the knuckle. Then thread the bolts into the bearing flange far enough to hold the assembly in place.
9. Install the remaining bolts. Tighten the hub/ bearing bolts to 166 Nm (122 ft. lbs.)
10. Install the washer and hub nut and tighten to 245 Nm (180 ft. lbs.).
