Solution

1. Preparation

• Tools Required: Socket set, torque wrench, screwdrivers, safety gloves, and safety glasses.
• Ensure the vehicle is on a flat surface and securely lifted using jack stands.
• Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Steering Wheel

• Sub-steps:
  1. Remove the airbag (if equipped) by unscrewing the retaining screws on the back of the steering wheel.
  2. Disconnect the airbag connector carefully, ensuring no damage occurs.
  3. Unscrew the central nut holding the steering wheel in place and use a steering wheel puller if necessary to remove it.

  2. Install new parts in the reverse order of removal, ensuring that all connections are tight and secure.
  3. Torque all bolts to the specified values found in the service manual.
