Solution

1. Preparation

• Gather all necessary tools and replacement parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical issues.

2. Check and Top Off Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; add the appropriate fluid if low.
• If fluid is discolored or has debris, proceed to replace the fluid.

3. Inspect and Replace Power Steering Pump

• Tools Required: Socket set, wrench set, power steering fluid, drain pan.
• Remove any covers obstructing access to the power steering pump.
• Disconnect the fluid hoses from the pump using a wrench and drain fluid into a pan.
• Unbolt the pump from its mounting bracket and remove it.
• Install the new pump in reverse order of removal, ensuring all bolts are torqued to manufacturer specifications.

4. Inspect and Replace Serpentine Belt

• Tools Required: Serpentine belt tool or socket set.
• Check the condition of the serpentine belt for cracks or wear.
• If damaged, remove the belt by releasing tension using the tensioner tool.
• Install the new belt, ensuring it follows the correct routing path.

5. Check Steering Rack and Tie Rods

• Inspect the steering rack for any visible leaks or damage.
• Check tie rod ends for play by shaking them while the vehicle is on the ground.
• If any component is worn, replace it accordingly.
