why does my Toyota RAV4 Fifth Generation (2019-present) make a whining sound when I turn the wheel?

Solution

1. Preparation

• Gather tools: socket set, torque wrench, screwdriver, fluid catch basin.
• Park the vehicle on a level surface and ensure the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
• If low, add the recommended power steering fluid (check owner's manual for specifications).
• Replace the cap securely.

3. Inspect and Replace Serpentine Belt (if necessary)

• Locate the serpentine belt and inspect for cracks, fraying, or excessive wear.
• If damaged, use a wrench to relieve tension on the tensioner and remove the old belt.
• Route the new serpentine belt according to the belt routing diagram (usually found on a sticker in the engine compartment).
• Ensure the belt is seated correctly on all pulleys and reapply tension.

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

• Remove the power steering pump by disconnecting the fluid lines and unbolting it from the engine.
• Install the new power steering pump, ensuring all connections are tight and secure.
• Refill the power steering fluid to the appropriate level.

5. Check Steering Rack and Pinion (if necessary)

• Inspect the steering rack and pinion for any signs of leaks or physical damage.
• If damage is found, remove the steering rack by disconnecting tie rod ends and unbolting it from the chassis.
• Install a new steering rack and ensure proper alignment of tie rods before tightening bolts to the manufacturer’s torque specifications.
