How is the top bar going to pull if it's on the push side of the axle..??????

Dave,

He's correct. If both were pushing, the axle would have to move, because the 4-bar ends are all that's holding it in place.

Check the diagram. If you torque the axle, it will try to rotate clockwise. It will use the top 4-bar eye as a pivot point, causing a pull, and push on the lower 4-bar eye.

For the axle not to move, the sum of the forces in the 4-bars have to be equal, and in opposite directions.

Of course, none of this means that it's a good setup.
