On our rigs the unit bearing hub is pressed together and not held together mechanically. The only thing keeping it together is the press fit and the stub shaft. Never use a hub puller without the stub shaft inplace and torqued down.

Start your rig and turn the wheel to the passenger side.
Have an assistant hold a socker between the inner shaft u-joint ear and the stub shaft ear. Slowly turn the steering wheel toward the drivers side and let the PS pump do the work for you.

 

OK...I see the picture on the earlier post. I'll get the little suckers out tomorrow.
