Reply to enginboy's Post: thanks for the illistration, but do i need any special tool to remove the steering wheel?
Expert:  Marc replied 11 years ago.
 Yes you need a puller to get the wheel off that should be the only special tool you need. You can borrow the puller from your local autozone store if you leave a deposit.
