Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, fluid catch pan.
Ensure the vehicle is on a flat surface and the engine is off. Disconnect the battery to avoid any electrical issues during repairs.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the manufacturer-recommended fluid if low.
Inspect fluid condition; if dirty or contaminated, proceed to replace the fluid.

3. Inspect Power Steering Pump

Tools Required: Wrench set.
Locate the power steering pump and check for proper belt tension and condition.
Start the engine and observe the pump operation; listen for unusual noises indicating pump failure.
If the pump is faulty, replace it by removing the drive belt and unbolting the pump from its mount. Install the new pump and reattach the drive belt.

4. Examine Steering Rack and Pinion

Tools Required: Socket set, torque wrench.
Safely lift the vehicle and remove the front wheels for better access.
Inspect the steering rack for any visible signs of leakage or damage.
If the steering rack is damaged, remove it by disconnecting the inner tie rod ends and unbolting it from the frame. Install the new rack and ensure all connections are secure.

5. Inspect Suspension Components

Check control arms, tie rods, and bushings for wear or damage.
Replace any worn components; for example, remove the affected control arm or tie rod assembly using a socket set, and install the new part, ensuring to torque all bolts to manufacturer specifications.
