Solution

1. Preparation

Gather tools and parts required for repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Power Steering Fluid

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

3. Inspect and Replace Power Steering Hoses

Visually inspect all power steering hoses for cracks, leaks, or wear.
Use a socket set to remove any damaged hoses.
Install new hoses, ensuring tight connections and no kinks.
Refill the power steering fluid reservoir.

4. Test and Replace Power Steering Pump (if necessary)

With the engine off, disconnect the power steering pump from the serpentine belt.
Use a multimeter to check the pump motor (if applicable).
If the pump is faulty, remove it using appropriate sockets and replace it with a new unit.
Reconnect all lines and the serpentine belt.

5. Inspect and Replace Steering Rack (if necessary)

If the steering rack is damaged, lift the vehicle and support it securely.
Disconnect the steering tie rods and unbolt the rack from its mounts.
Install a new steering rack, making sure to align it properly, and reconnect all components.
