Inspection and verification
1. Check the customer's complaint.
2. Visually inspect for obvious signs of mechanical or electrical damage.
|
Mechanical factors |
Electrical Factors |
|
• Tire pressure • Accessory drive belt • Wheels and tires • Leakage of working fluid in the lines of the power steering |
• Power steering pressure switch (PSP) |
3. If an obvious cause of the problem you identified or described by the client is found, eliminate it before proceeding to further actions (if possible).
4. If the cause is not visually obvious, check the symptom and refer to the Symptom Chart.

Item checks
Inspect the steering gear boots for cuts, misalignment, twisting, or deformation. Make sure the covers are secure. Install new boots or clips if necessary.
1. Park the vehicle on a dry, level, level surface and apply the parking brake. center steering (position "straight ahead").
2. With the engine running, gently turn the steering wheel to the right and left to check for play. The play is measured at the steering wheel rim and must be within the limits prescribed by the specification. If the amount of play is outside the prescribed limits, then the steering gear or steering column is worn out, or there is an increased backlash in the steering mechanism.
3. If the steering drive is worn out, install new elements if necessary. See Section 211-03 for more information. The steering column cannot be repaired, install a new column. See Section 211-04 for more information. The side clearance of the steering gear cannot be adjusted, install a new steering gear. See Section 211-02 for more information.
4. With the engine off, grasp the steering wheel and hold it firmly with both hands. Try moving the steering wheel up and down and also left and right without turning it. This checks for wear in the steering column bearings, clearance in the steering column shaft pivot, and slack in the steering wheel or steering column. If play is found, check that the steering column bolts, steering column shaft coupling and steering wheel are properly tightened. The steering column is beyond repair, install a new steering column. See Section 211-04 for more information.
