Solution

1. Preparation

Gather tools: socket set, torque wrench, power steering fluid, cleaning cloths, and safety gloves.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Check and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check the fluid level; if low, add the appropriate power steering fluid as per the manufacturer’s specifications.
If the fluid appears dark or contaminated, drain the old fluid using a siphon or turkey baster, then refill with new fluid.

3. Inspect and Replace Power Steering Components

Check the power steering pump for leaks or noise. If defective, remove the pump by:
- Disconnecting the power steering lines with a wrench.
- Unbolting the pump from its bracket.
- Installing a new power steering pump by reversing the steps.
Inspect and replace any damaged hoses connected to the pump.

4. Inspect Steering Linkage

Raise the front of the vehicle using jack stands for safety.
Visually inspect tie rod ends and ball joints for play or wear.
If any components are worn, replace them by:
- Removing the old part using a socket and ratchet.
- Installing the new part and torqueing to manufacturer specifications.

5. Reassemble and Lower the Vehicle

Ensure all components are properly secured and reattach any covers removed during inspection.
Lower the vehicle and perform a final check of the steering system.
