Once you get the wheel off, carefully clean the wheel center hub and the rotor hub. The SAAB wheels are "hub-centric", which means that the center hub on the wheel fits very closely over the hub on the rotor to 'center' the wheel on the rotor. Something like WD-40 and an old rag works well to clean both surfaces. If the rotor hub is really rusty, a little steel wool may be called for.
After cleaning the wheel and rotor hubs, apply a small amount of anti-seize compound or high temperature silicone grease to the wheel and rotor hubs to prevent future corrosion problems. Once lubricated the wheel comes off the hub much easier.
As far as the Direct Ignition Module (DI cassette), spark plug changes on the four cylinder turbo Saabs are really very easy.
Disconnect the wire harness to the DI cassette.
Remove 4 torx screws with the screw driver in the trunk.
Pull straight up on the DI cassette, and lay back to the side on its back.
Use a shop vacuum or house vaccuum to throughly clean the 'wells' around he spark plugs prior to removal of the spark plugs.
Remove the plugs...replace with only NKG's spark plugs, gap .039", and torque to 20 ft-lb.
Put a small amountof silicone 'dielectric' grease on the DI cassette spark plug boots.
Reinstall the DI cassette pushing straight down to seat the spark plug boots.
Repalce the torx screws.
Reinstall the DI cassette wire harness.
