Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be within the recommended range.
If low, fill with the appropriate power steering fluid (consult owner’s manual for specific type).
Inspect fluid for contamination; if cloudy or dark, it may need to be flushed.

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

Tools Required: Socket set, wrench set, power steering fluid.
Remove the serpentine belt by releasing tension from the tensioner pulley.
Disconnect the power steering fluid lines from the pump (use a catch basin for fluid).
Remove the mounting bolts of the power steering pump and take it out.
Install the new power steering pump by reversing removal steps.
Reconnect the fluid lines and ensure they are tight.
Reinstall the serpentine belt, ensuring it is correctly aligned.

4. Inspect Steering Linkage

Check all steering components including tie rods, ball joints, and the rack and pinion for wear or damage.
If any components are found faulty, replace them as needed. Follow specific torque specifications during reassembly.

5. Refill and Bleed Power Steering System

Refill the power steering fluid reservoir with the appropriate type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level again and top off if necessary.
