REPLACEMENT WHEELS
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, air leak through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than specification may cause objec-
tional vibrations.
Replacement wheels must be equivalent to the original equipment
wheels in load capacity, diameter, rim with offset and mounting
configuration. A wheel of improper size or type may affect wheel
and bearing life, brake cooling, speedometer/odometer calibra-
tion, vehicle ground clearance and tire clearance to body and chas-
sis.
HOW TO MEASURE WHEEL RUNOUT
To measure the wheel runout, it is necessary to use an accurate
dial indicator. The tire may be on or off the wheel. The wheel should
be installed to the wheel balancer of the like for proper measure-
ment.
Take measurements of both lateral runout and radial runout at both
inside and outside of the rim flange. With the dial indicator set in
place securely, turn the wheel one full revolution slowly and record
1. Radial runout
every reading of the indicator.
2. Lateral runout
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
