It should only cost about $50-$90 to replace the Flywheel of a 2000 Ford Windstar, is a person is doing the work themselves. If they are not it can cost $150+ depending on labor charges.
If you open the door there will be a star head bolt in the door jam on the speaker grille, you just unbolt this and it should come right off.
I recently just changed my door speakers front and back. The front just requires a special star bit to get the screws out of the door panel. Once the door panel is off or at least pulled away far enough to get to the speakers themselves, all you need is a Phillips screwdriver for the 4 screws that mount the speaker to the door frame. Remember to have patience and not just jerk the panel off, because it has pop rivets that will be tore up as well. And there are 3 star bits, or Phillips heads that have covers on them that are actually in the door themselves. One by the arm rest on the door, one towards the front by the lower front and one towards the lower rear.
first pop up and pull out the bottom seat then use a star head bit an rachet to pull off the back rest of the back seat then the back panel covering the speakers should come out.
The original front suspension and steering joints are not serviceable but hinges and locks/latches and such can be lubricated.
