VOLKSWAGEN
Type 1 - Raise front of behicle and turn steering to one side. Place pry bar tool over nut or bolt head mounting steering knucle to strut. Compress ball joint spring and place vernier caliper over top of ball joint and over bottom stud. Note caliper reading, then release lever and record caliper travel. Increase reading is ball joint play. Replace ball joints as necessary
Type 2 - Raise front of vehicle and turn steering to one side. Insert pry bar tool VW 281a (or equivalent) under lower control arm and over top of strut mounting. Fit a vernier caliper on lower or upper torsion arm and steering knuckle. Record measurement. Press down with lever and measure travel of vernier caliper. IF travel exceeds specifications, replace ball joint.
