Solution

1. Preparation

Gather tools: socket set, wrench set, power steering fluid, and a fluid catch pan.
Ensure the vehicle is parked on a level surface, and the engine is turned off.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Open the reservoir cap and check the fluid level against the dipstick or markings.
If low, add the appropriate power steering fluid as specified in the owner’s manual until it reaches the correct level.

3. Check for Leaks

With the engine running, inspect the power steering pump and hoses for any leaks.
If leaks are found, replace the affected hoses or the pump as necessary.

4. Replace Power Steering Pump (if faulty)

Disconnect the negative battery terminal for safety.
Remove the drive belt from the power steering pump.
Unbolt and remove the power steering pump from its mounting bracket.
Install the new power steering pump, making sure to torque bolts to the manufacturer’s specifications.
Reconnect the drive belt.

5. Bleed the Steering System

Fill the power steering fluid reservoir to the proper level.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check fluid level again and add more fluid if necessary.
