Bleeding is easy. With front raised and the engine off, slowly turn the wheel from lock to lock several times, pausing for a few seconds at each lock. Then with the wheels on the ground and the engine running, do the same thing again. Inspect the fluid and keep repeating the process until no air is visible.
When I changed out my rack, the biggest hurdle was removing the pressure line from the rack. It was totally seized and I had to cut the line and buy a new one. The techs at the dealer told me this was fairly common.
Good luck.
