Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off with manufacturer-recommended power steering fluid if low.
Inspect fluid for contamination; if dirty, proceed to fluid replacement.

3. Inspect and Repair Power Steering System

Fluid Replacement:
- Using a turkey baster, remove old fluid from the reservoir.
- Refill the reservoir with new power steering fluid.
- Start the engine and turn the steering wheel from lock to lock to purge air from the system.
Inspect Power Steering Pump:
- Check for proper operation by listening for unusual noises while the engine is running.
- If the pump is faulty, replace it by:
  1. Disconnecting the power steering lines using appropriate wrenches.
  2. Unbolting the pump from its mounting bracket.
  3. Installing the new pump and reconnecting the lines.

4. Inspect Steering Linkage and Suspension

Examine the tie rods, ball joints, and other components for wear.
Replace any worn or damaged parts by:
1. Removing the affected component (e.g., tie rod ends) using a socket set.
2. Installing the new component and tightening to manufacturer specifications (usually specified in the service manual).

5. Wheel Alignment

After replacing any components, perform a wheel alignment to ensure proper handling.
Take the vehicle to a professional alignment shop or use an alignment tool if equipped.
