If its anyhting like my wife's 2000 - you have to remove the rear seat to gain access to the grill/speaker area. There is a latch you pull outward which is located towards the center of the rear bottom seat to remove the bottom. Then you see the bolts to remove the seat back. You might have to remove some trim pieces as well. then remove the carpet covering the speakers.
All sides are 6" by 8".
To remove a pulley, you typically need to use a pulley puller tool. First, release tension on the belt connected to the pulley. Then, follow the specific instructions for your vehicle or equipment to use the pulley puller to gently remove the pulley without damaging surrounding components.

You will need to remove the tire and wheel from your 1998 Pontiac Grand Am. Remove the brake assembly spring from the brake pads. The brake pads will come off. Reverse the process to install the new brake pads.
I did this with my 1996 Lumina APV. If you have rear speakers, remove the speaker cover(s), remove the speaker and reach in and find the mechanism, turn it to open. May have to do simultaneously for both sides. Then remove the tailgate panel and repair.
