Tools Required: Socket set, torque wrench
Inspect the steering rack mounting bolts and tie rod end nuts.
Tighten any loose bolts to the manufacturer’s specifications (consult the vehicle service manual for specific torque values).

3. Replace Worn or Damaged Components

Tools Required: Jack, jack stands, socket set, pliers
If any components such as tie rods or the steering rack show excessive wear, proceed to replace them:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel for better access.
3. Detach the tie rod end from the steering knuckle using a ball joint separator.
4. Remove and replace with a new tie rod end, ensuring to adjust the length to match the original.
5. Reattach and torque to specifications.
6. Repeat for any other damaged parts.

4. Power Steering Fluid Check and Replacement

Tools Required: Fluid funnel, rags
Check the power steering fluid reservoir for proper level and condition:
