Steering Linkage Inspection


Vertical Inspection

NOTE: Checking the steering linkage components for vertical (up and down) deflection is preferred, however it may be necessary to check some steering linkage components for lateral (side-to-side) deflection due to lack of clearance for the dial indicator. Outer tie-rod ends should always be checked for vertical deflection. Using a vice grip style, flexible arm dial indicator (such as Snap On(R) stock # GA3634) is suggested.

NOTE: The steering linkage component ball studs are spring loaded and will normally have a small amount of vertical deflection when the spring is compressed. However, excessive vertical deflection of the studs relative to the sockets may indicate excessive wear.

1. Turn the steering wheel to the straight-ahead position and turn the ignition switch to the OFF position.

2. With the vehicle in NEUTRAL, position it on a hoist. Refer to Jacking and Lifting Service and Repair.

3. NOTE: To obtain the necessary clearance to install the dial indicator, it may be necessary to remove the wheel and tire.

If necessary, remove the wheel and tire. Refer to Wheels and Tires Removal and Replacement.

4. NOTE: Typical steering linkage shown.

Install the dial indicator as shown.

1. Attach the vise grip/flexible arm to the nut of the steering linkage component being tested or the component that the steering linkage ball stud seats into.

2. Position the flexible arm so that the dial indicator is positioned on the center of the steering linkage component cap and lock the flexible arm.





5. Grasp the steering linkage component forging near the ball stud, push upward, pull downward, and then release it. This will allow the steering linkage component to be in a relaxed position when measuring.

6. Zero the dial indicator.

7. NOTE: Make sure that the steering linkage component does not roll during inspection or an inaccurate measurement may occur.

Using a suitable prying device (approximately 457 mm [18 in] long), pry on the steering linkage component forging while observing the deflection of the dial indicator pointer.

- Only apply moderate force. Do not move the vehicle suspension.

8. If the vertical deflection exceeds 2.30 mm (0.09 in), install a steering linkage component.


Lateral Inspection

NOTE: Checking the steering linkage components for vertical (up and down) deflection is preferred, however it may be necessary to check some steering linkage components for lateral (side-to-side) deflection due to lack of clearance for the dial indicator. Outer tie-rod ends should always be checked for vertical deflection. Using a vice grip style, flexible arm dial indicator (such as Snap On(R) stock # GA3634) is suggested.

1. Turn the steering wheel to the straight-ahead position and turn the ignition switch to the OFF position.

2. With the vehicle in NEUTRAL, position it on a hoist. Refer to Jacking and Lifting Service and Repair.

3. NOTE: Typical steering linkage shown.

Install the dial indicator.

1. Attach the vise grip/flexible arm to the nut of the steering linkage component being tested or the component that the steering linkage ball stud seats into.

2. Position the flexible arm so that the dial indicator is positioned on the end of steering linkage housing and lock the flexible arm.





4. Have an assistant grasp the tire and move the steering linkage from side-to-side. Observe and record the deflection measured with the dial indicator.

5. If the lateral deflection exceeds 1.30 mm (0.05 in), install a new steering linkage component.
