Vehicle should have a full tank of fuel.
-
Before measuring ride height check:
-
Tires are inflated to the correct pressure.
-
Vehicle should have a full tank of fuel.
-
All fluids at proper levels.
-
No cargo inside the cab or bed.
-
Inspect for aftermarket equipment. Check for

Ride Height Measurement — Front
-
-
Ride height = 3-2
-
Measure the distance between the flat level
surface and the center of the rear control arm ball joint cap
(measurement 2)
-
Measure the distance between the flat level
surface and the center of the rear control arm inboard 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.
Ride Height Measurement — Rear
-
-
Ride height = 2-3
-
Measurement 2
-
Measurement 3
Use the General Equipment: Surface Gauge
-
Measure the distance between the flat level surface
and the center of the toe link inboard cam bolt (measurement 2).
-
Measure the distance between the flat level surface
and the center of the toe link outboard bolt (measurement 3).
-
