Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level.
If low, add the manufacturer-recommended power steering fluid.
Inspect the fluid for contamination or burnt smell, which may indicate a system issue.

Look under the vehicle for signs of power steering fluid leaks.
If leaks are found, trace the source to hoses, seals, or the steering rack.
Replace any damaged components as necessary.

4. Replace Power Steering Pump (if defective)

Locate the power steering pump.
Remove the drive belt by loosening the tensioner.
Disconnect the power steering lines from the pump, using a wrench and capturing any fluid in a container.
Unbolt the pump from its mounting bracket.
Install the new pump by reversing the removal steps.
Refill the power steering fluid and bleed the system according to the manufacturer’s specifications.

5. Inspect and Replace Steering Rack (if necessary)

Lift the vehicle securely and remove the front wheels.
Disconnect any components obstructing access to the steering rack (e.g., tie rods).
Unbolt the steering rack from its mounts and disconnect the input shaft.
Install the new steering rack and reconnect all components.
Ensure all fasteners are torqued to specifications and the alignment is checked afterwards.
