Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery to avoid electrical issues.

2. Check Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Remove the cap and check the fluid level. If low, add manufacturer-recommended power steering fluid.
- Inspect the fluid for contamination (e.g., discoloration or debris) and replace if necessary.

3. Replace Power Steering Pump (if faulty)

Sub-steps:
- Remove any components obstructing access to the power steering pump (e.g., brackets, hoses).
- Disconnect the power steering lines (be cautious as fluid may leak).
- Remove the mounting bolts securing the pump and take out the old pump.
- Install the new power steering pump, ensuring all bolts are torqued to manufacturer specifications.
- Reconnect the power steering lines securely and check for leaks.

4. Align Steering Components

Sub-steps:
- Inspect tie rods and control arms for signs of wear; replace if necessary.
- Perform a wheel alignment using a professional alignment machine to ensure proper steering geometry.
