why does my Toyota Camry XV70 (2018-2024) make a whirring sound when steering

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Raise the vehicle if necessary and secure it on jack stands.

2. Inspect and Top Off Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; if low, add the manufacturer-recommended fluid.
• If the fluid is contaminated (dark or gritty), proceed to flush the system.

3. Replace Power Steering Pump (if defective)

• Tools Required: Socket set, torque wrench, power steering fluid catch pan.
• Sub-steps:
  1. Disconnect the power steering hose from the pump using appropriate wrenches.
  2. Remove the mounting bolts securing the power steering pump to the engine.
  3. Carefully remove the pump from its bracket and disconnect any electrical connectors.
  4. Install the new power steering pump by reversing the removal steps.
  5. Torque the mounting bolts to the manufacturer's specifications (typically around 18-25 ft-lbs).
  6. Reconnect the power steering hoses and electrical connectors.

4. Replace Serpentine Belt (if worn)

• Tools Required: Socket set, belt tensioner tool.
• Sub-steps:
  1. Use a belt tensioner tool to relieve tension on the serpentine belt.
  2. Remove the old belt from all pulleys.
  3. Route the new belt according to the diagram located on the engine bay.
  4. Reapply tension using the tensioner tool and ensure proper alignment.

5. Refill and Bleed Power Steering System

• Fill the power steering reservoir with the appropriate fluid.
• Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
• Check fluid level again and top off as necessary.
