well I just went through the same thing last month. Nightmare!! Dealership was expensive and on National backorder. That kit included the pump, pulley, reservoir, and a belt. All auto parts stores will sell a rebuild with no pulley. That pulley is worth more than gold right now so make sure you have someone with a successful track record pull the pulley off your old pump. Repair manual specifically says not to reuse the pulley though. If your 2006 is like my 03 you will most likely be replaceing the steering gear box, and the Brake booster. $1500 repair at the shop I used $2500 at the dealer. My pulley was broken during removal, thats where the nightmare came in. I ended up calling about 20 wrecking yards before I found a pump with a pulley. I decided to put the used pump on rather than risk pulling that pulley to place on the rebuild pump that has a bad record of repeat failures.
I know not exactly what you asked, but I hope you find this helpful.
