Disconnect the negative battery terminal for safety.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; top off with manufacturer-recommended fluid if low.
Check for contamination (dark or milky fluid) which may indicate a need for a fluid flush.

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

Tools Required: Socket set, torque wrench, power steering fluid.
Remove the drive belt by loosening the tensioner pulley.
Disconnect the power steering pump hoses using appropriate wrenches, and allow fluid to drain into a container.
Remove the mounting bolts securing the pump to the engine and take out the pump.
Install the new power steering pump by reversing the removal process, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer’s specifications.

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

Tools Required: Hose clamps, pliers, wrench set.
Identify any damaged hoses leading to/from the power steering pump and steering rack.
Use pliers to remove any hose clamps and disconnect the damaged hoses.
Install the new hoses, ensuring they are properly routed and secured with hose clamps.

5. Bleed the Power Steering System

Fill the power steering reservoir with fresh fluid.
Start the engine and turn the steering wheel fully left and right several times to purge air from the system.
Check fluid levels and top off if necessary.
