There is only one way to install it and that is through the front of the torque tube. If you not happy with it, or think it is installed incorrectly, install a new one. To install a new one all you have to do is make the sure the old one is not "pinned" and use the new one to push the old one down the tube as you tap the new one in. Then reassemble u-joint retainer and bell.
