assembly ends or joints. Do not rock the tires with the vehicle
on the ground or with the wheels raised. Damage to
components can result.
10. Apply hand pressure of approximately 100 pounds (45 kg) in a
vertical PUSH-and-PULL motion several times. Check for any
movement or looseness at both tie rod ends. Figure 3.7.
If there is any movement in the tie rod assembly:
Replace both tie rod ends.

parts of the same length, diameter and threads. Do not
attempt to straighten a bent cross tube. Damage to
components can result.
11. Inspect the cross tube and clamps for damage. Figure 3.8.
If the cross tube is bent or cracked: Replace it. Use
original equipment parts of the same length, diameter and
threads.
If the clamps are damaged: Replace them.

Replace the entire cross tube assembly. Use original
equipment parts of the same length, diameter and threads.

Federal Out of Service Roadside Inspection
Criteria (Department of Transportation)
The following cross tube and tie rod end components may be
checked during roadside inspections. Deficiencies may result in the
vehicle being placed out-of-service by authorized personnel.
1. Loose clamps or clamp bolts on the tie rods.
2. Any looseness in the threaded tie rod end and cross tube joint.
3. Loose or missing nuts on the tie rods or cross tube.
4. Any movement under the steering load of a tie rod arm ball
stud nut.
5. Any motion, other than rotational, between any linkage
member and its attachment point of more than 0.125-inch
(3 mm), when measured with hand pressure.
6. Any obvious welded repairs.
Replacement Criteria
Any detectable movement of 0.125-inch (3 mm) or more requires
that the vehicle is immediately taken out of service for replacement
of the tie rod ends.
When the roadside check indicates tie rod end movement of less
than 0.125-inch (3 mm), the vehicle does not need to be
immediately removed from a service run. It is advisable to schedule
a major out-of-service inspection and maintenance as soon as
possible.
