Hub Bearing Setting
• Torque hub nut to 238-263 lbs. ft. (323-357
N•m).
Note: The hub should be fully rotated several times
in both directions to ensure the hub bearings are
correctly seated.
• Secure a cord to a wheel stud and wrap cord
around hub, fasten free end to a spring balance.
• Apply a steady pull to spring balance and note
reading, ignoring the large force initially required
to start rotation.
• The correct spring balance reading should be
between 8.5 to 12 lbs. (3.8 to 5.4 kg) corre-
sponding to a hub rolling torque of 7-9 lbs. ft. (9-
12 N•m).
• If spring balance reading is outside limits stated,
adjust hub nut and check again, continuing until
correct figure is obtained.
• When hub setting is correct, fit lockrings, then
retaining ring.
Note: To align slots in nut with corresponding slots
in axle spindle, do not back off. Continue to tighten
nut until slots are aligned.
