I don't understand a 'passenger wheel lip,' could you post a photo or give more details? If you're talking about a wheel cover, they are often held on by a lug on a stud hidden under a chrome lug cover.

terrycx, there are a couple of screws on each side. Once they are removed the wheel lip will swing up on a hinge across the top, then remove the screws in the hinge.
For future reference please add your coach info to your signature.
