my Volkswagen Tiguan has a strange noise when I turn the wheel, what should I check?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; top off with manufacturer-recommended fluid if low.
• Inspect the fluid for contamination or debris.

3. Inspect Steering Components

• Steering Rack Inspection

  • Visually inspect the steering rack for leaks or physical damage.
  • Ensure the mounting bolts are tight.

• Tie Rod and Ball Joint Inspection

  • Raise the front of the vehicle using a jack and secure it with jack stands.
  • Grasp the tie rod ends and check for excessive play.
  • Inspect the ball joints for wear by moving the wheel side to side while observing joint movement.

4. Test Power Steering Pump

• Start the engine and listen for any whining or grinding noises from the power steering pump.
• Turn the steering wheel fully to the left and then to the right several times. Observe for any abnormal sounds.

5. Replace Damaged Components (if necessary)

• If any components are found to be damaged during inspection:
  • Remove the old component (e.g., steering rack, tie rod, or ball joint) by loosening the securing bolts and disconnecting any attached parts.
  • Install the new component and secure it to manufacturer specifications.
  • Reconnect the power steering fluid lines if the pump was replaced.
