why does my Toyota RAV4 Fifth Generation (2019-present) make a grinding noise when steering?

Solution

1. Preparation

• Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to ensure safety while working.

2. Check and Refill Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level. If low, add the recommended power steering fluid until it reaches the proper level.
• Inspect the fluid condition; if it appears dirty or contaminated, a fluid flush may be necessary.

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

• Tools Required: Wrench set, power steering pulley puller, new power steering pump.
• Remove the serpentine belt by loosening the tensioner.
• Disconnect the power steering hoses from the pump, allowing fluid to drain into the catch pan.
• Unbolt the power steering pump from its mounting bracket and remove it from the engine bay.
• Install the new power steering pump by reversing the removal steps and ensuring all connections are secure.

4. Check Steering Rack and Tie Rods

• Inspect the steering rack for any signs of internal damage or leaks.
• Check the tie rods and ball joints for play or wear using a pry bar.
• If any components are worn, replace them using appropriate tools and torque specifications.

5. Reassemble and Test

• Reattach all components in reverse order.
• Reconnect the negative battery terminal.
• Start the engine, turn the steering wheel from lock to lock, and check for any noises.
• Ensure the power steering fluid is at the correct level after any work.
