Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, multimeter, power steering fluid.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; add the manufacturer-recommended power steering fluid if low.
If the fluid appears dark or contaminated, drain the system using a fluid catch pan.
Refill with new power steering fluid until it reaches the proper level.

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

Tools Required: Wrenches, socket set, torque wrench.
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering lines from the pump.
Unbolt the power steering pump from its mount and remove it.
Install the new power steering pump, tightening bolts to manufacturer specifications (usually around 18-25 ft-lbs).
Reconnect the power steering lines and the serpentine belt.

4. Inspect Steering Column and Joints

Remove any covers from the steering column to access the joints.
Check for any binding or obstruction in the steering column.
Lubricate any joints that appear dry or stiff to ensure smooth operation.

5. Reassemble and Test

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock to bleed air from the power steering system.
Check the fluid level again and top off if necessary.
