Please forgive a potentially dumb question, but...
Since it sounds like it can be very difficult to remove the thrust arm ball joint shafts from the plates to which it attaches (the forward end), requiring a puller, etc., etc., could they be more easily and quickly separated by:
1. Lifting car with wheels still on
2. Removing the nuts
3. Placing a jack under each arm
4. Slowly lowering the car, placing its weight onto each arm and jack, until the ball joint shaft comes loose from the plate? (assuming something was tied around the arm to prevent it from slapping up against other parts when it pops off)?

Feasible? Does anyone do it this way? Just checking. Thanks
