The Grand Marquis has shocks, not struts. They are simple bolt on parts.
Yes they should the bolt pattern is the same.
Wheels from a 1995 Mercury Grand Marquis are unlikely to fit a 2002 Ford Explorer without modifications. The bolt pattern and offset may differ between the two vehicles, and the Grand Marquis typically has larger diameter wheels. It's best to check the specifications, including bolt pattern, wheel diameter, and offset, to ensure compatibility before attempting to swap the wheels.
