The right way to do this is while the rack is off the car and the rack end is clamped in a vise. A big pipe wernch or channel lock will get it off after you chisel off the bent over lock section.
Using the pipe wernch when the rack is on the car runs the risk of damaging the rack internals.
These later CAM2 type of racks aren't meant to have the tie rods replaced. When they're bad, so is the rest of the rack. Just look at it this way, once you replace the tie rods and a few k miles later the rack itself goes bad, you'll be getting two new tie rods anyway and you just wasted the $$'s on tie rods and time to do this last year.
IMHO, this procedure is not worth doing. I would get the remanufactured rack with new end instead.
