Measure the camber, the vertical surface of the hub or tire, with a level. Do that with the tire pointed straight ahead. Turn the wheel full lock each way, measuring again. If all three are the same, you have Zero caster. If the csmber angle gets bigger one way, and smaller the other , you have some caster. You'll have to do some cogitating to figure whether plus or minus, and much math (Trionomerty?) to figure how mush. Alignment equipment does it this way, automatically.
