Is it a rear wheel drive or front wheel drive. I am guessing rear wheel, as per other Escorts. The proceedure is the same as per any other rear wheel drive car, undo the drakes, undo the retaining plate, pull the axle. FWD is different, but similar. remove the brakes, undo the bearing at the front, ( really big extension bar needed, maybe a meter long) remove disc etc., pull axle.
