STEERING COLUMN
If the vehicle is involved in a front end collision/the air bag has deployed the column must be inspected. This inspection will determine if the Column has collapsed. Inspect the column mounting capsules visually and manually push and pull them to check for separation or fractures. If capsules are fractured or have moved the column MUST be replaced.
OUTER TIE ROD END
Note. If the outer tie rod end is equipped with a lubrication fitting, grease the joint then road test the vehicle before performing test.
- Raise the front of the vehicle. Place safety floor stands under both lower control arms as far outboard as possible. Lower the vehicle to allow the stands to support some or all of the vehicle weight.
- Remove the front tires.
- Mount a dial indicator solidly to the vehicle steering knuckle and then zero the dial indicator.
- Position indicator plunger on the topside of the outer tie rod end. NOTE: The dial indicator plunger must be perpendicular to the machined surface of the outer tie rod end.
- Position a pry bar in order to pry downwards on the outer tie rod end.
- If the travel exceeds 0.5 mm (0.020 in.), replace the outer tie rod end «(Refer to REMOVAL)»(ref-247608-S22155228812007020100000) .
- If the outer tie rod end is within specs reinstall the front tires «(Refer to STANDARD PROCEDURE)»(ref-247607-S28535931232007020100000) .
