Hi, I am sending the parking brake shoe replacement Instructions for your truck. I know it is tight working behind the axle flange,it f you cant seem to get your hands in to replace the shoe,you may find it easier to remove the axle . This will require pulling the differential cover and taking the pin out to remove the C washers that hold the axle. I hope this will help you to get he brakes done,thanks Jerry.
Only the Mountaineer and 1995-99 Explorer models use separate parking brake shoes.
