Install valve stems of dual wheels
180 degrees opposite each other.
1. Finger-tighten the nuts.

torque in order as shown.
Never use oil or grease on the
studs or nuts.
3. If a wheel stud and nut has
been replaced, stake the stud

Warning
To help reduce the risk of losing
vehicle control and personal
injury or death, if any stud has
been damaged as a result of a
loose running wheel, all studs for
that wheel should be replaced.
A loose running wheel may cause
only one stud to break but
damage to other studs may not
be noticeable. If stud holes in a
wheel have become elongated or
distorted, replace the wheel.
