SW2 L4-1.9L DOHC VIN 7 (1997)
Wheels: Initial Inspection and Diagnostic Overview
Measuring Wheel Runout
Wheel runout should be measured with an accurate dial indicator. Measurements may be taken with the wheel installed on the vehicle (be sure wheel
bearings do not have excessive free play) or off the vehicle on an accurate mounting fixture (such as a wheel balancing machine). Measure the radial and
lateral runout of both the inboard and outboard rim flanges.
1. Place dial indicator in a rigid fixture and position against wheel.
2. Slowly rotate the wheel one full revolution while observing dial indicator.
3. Rotate wheel to position where lowest dial indicator reading was obtained.
4. Zero the dial indicator.
5. Slowly rotate the wheel one full revolution while observing dial indicator.
6. Record highest dial indicator reading. This is the wheel runout.
IMPORTANT: Disregard any indicator readings due to welds, scratches, paint runs, etc.

Replacement Inspection
A wheel must be replaced if it:
a. Is bent or dented.
b. Has excessive lateral or radial runout.
c. Leaks air through its welds.
d. Has stretched or oblong fastener holes or fasteners will not stay on tight.
e. Is excessively rusty, particularly in the bead area.
Replacement wheels must be equivalent to the original equipment wheels in load capacity, diameter, rim width, offset, and mounting configuration. A
wheel of improper size or type may effect wheel and bearing life, brake cooling, speedometer/odometer calibration, vehicle ground clearance, and tire
clearance to body and chassis.
NOTICE: Do not mix wheels of different size or construction on the vehicle. Vehicle handling may be seriously affected and may result in a loss
of control.
