Steering Linkage

NOTE: The steering linkage ball studs are spring loaded and will have a small amount of up and down movement if the spring is compressed. Do not use a prying device or adjustable pliers to check the steering linkage components.

Turn the steering wheel to the straight-ahead position and turn the ignition switch to the OFF position.
Raise and support the vehicle.
Check and, if necessary, adjust the front wheel bearings. See 1998-99 SUSPENSION, FRONT -- 2WD VAN or 2000 SUSPENSION, FRONT -- 2WD ECONOLINE .

NOTE: The flexible arm of the run-out gauge set must be attached to the steering linkage component that is closest to the component that is being tested. See Fig 1.

Install the tire and wheel Run-Out Gauge Set (164-R1099 or equivalent) to the steering linkage component being tested.

NOTE: Make sure to measure the side-to-side movement of each component using hand force only. See Fig 2.

Have an assistant grasp the tire and move the steering linkage from side-to-side. Observe and record the movement measured with the dial indicator.
If the movement exceeds 0.04 in (1mm) install a new steering linkage component.
