More than likely the uni-bearings will be destroyed when removing. I would take advantage of this and purchase the Dynatrac system for your front end and have a better system, and for pennies on the dollar since you have the cost of replacing the uni-bearings any way. And the little more that you pay for the Dynatrac system you will get back with better fuel MPG savings. I saw the Dynatrac system at a 4X4 show and was impressed with them, so if my front axle ever has issues I will purchase the Dynatrac setup. .
FYI There is no back ordering with the Dynatrac system.
