1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; top off with manufacturer-recommended power steering fluid if low.
Inspect fluid for contamination; if dirty, proceed to replace the fluid.

3. Replace Power Steering Fluid

Use a syringe or turkey baster to remove old fluid from the reservoir.
Refill with new power steering fluid.
Start the engine and turn the steering wheel from lock to lock to circulate the new fluid.
Check for any abnormal noises.

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

Remove the drive belt from the power steering pump.
Disconnect the power steering lines from the pump using a wrench.
Unbolt and remove the pump from its mounting.
Install the new pump by reversing the removal steps, ensuring all connections are secure.

5. Check Steering Rack and Column

Remove any obstructions or debris from the steering column.
Inspect the steering rack for any signs of wear or leaks; replace if necessary.
