Tools Required: Jack and jack stands, wrench set
Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and tie rods for any visible signs of damage or wear.
If damage is found, proceed to replace the affected components:
- Remove the cotter pin and nut from the tie rod end.
- Use a tie rod puller to disconnect the tie rod from the steering knuckle.
- Install the new tie rod and secure it with a new nut and cotter pin.

4. Suspension Component Replacement (if necessary)

Tools Required: Impact wrench, torque wrench
Inspect control arms and bushings for wear. If they are worn:
- Remove the bolts securing the control arm to the frame and knuckle.
- Replace with new components, ensuring proper alignment.
- Torque the bolts to the manufacturer's specifications.

5. Steering Pump Inspection and Replacement

Tools Required: Wrench set, fluid catch container
If the pump is noisy or failing:
- Disconnect the power steering lines and remove the pump from its mounting.
- Install the new pump and connect the lines, ensuring they are tight and leak-free.
