WHEEL AND RIM MOUNTING NUTS
Disc Wheels
1.
Mounting faces of the hub, wheel, and nut must
be free from dirt or excess paint.
Mounting faces which
have been damaged from wear or abuse must be
repaired or replaced.
2.
Right hand threads are used on the right side of
the vehicle and left hand threads on the left side.
3.
Tighten the wheel nuts alternately.
4.
Tighten the single wheel mounting stud nuts to
450-500 foot pounds torque.
5.
On dual wheels loosen the outer nuts before
attempting to tighten the inner nuts.
Tighten inner nuts
to 500 feet pounds torque and outer nuts to 450 foot
pounds torque.
NOTE:
Always tighten the inner nuts 50 foot
pounds more than the outer nuts and never let the
outer nuts get below 400 foot pounds.
It is good practice to repeatedly (daily) tighten the
wheel nuts during the first 500 miles of service on new
trucks and any time the wheels have been removed.
Regular inspection periods should be established to
assure keeping the nuts tight.
