squeaky wheel need help

The rf wheel on my 94 rs makes a squeaky noise when i get up 20 mph. I thought it was the brake pads but i cheaked and the pads are good. a buddy of my said its the wheel bearing. but the wheel dosen't have any play in it. I'm going to change the bearing anyway. I'm doing the work myself so if anyone has any good tip on the proceedure that would be great. diagrams or where to get diagrams would be even better.
