Ride Height Measurement - Front
NOTE:
Make sure that the vehicle is positioned on a flat,
level surface and the tires are inflated to the correct pressure.
Vehicle should have a full tank of fuel.
-
-
Ride height = 3-2
-
Measure the distance between the flat level
surface and the center of the lower arm forward bolt (measurement 2)
-
Measure the distance between the flat level
surface and the center of the ball joint pinch bolt (measurement 3)
Use the General Equipment: Surface Gauge
-
With the surface gauge positioned on a flat, level
surface, record the measurement of the surface gauge position
(measurement 2) and (measurement 3).
Use the General Equipment: Surface Gauge
-
Subtract measurement 2 from measurement 3 to obtain the front ride height.
