The procedure for bleeding the air out of the PS system on a '05 WK w/a 5.7 is to fill the reservoir, start the engine, shut off engine, and check fluid. You would do this until the level didn't go down anymore. From here you raise the vehicle, turn the wheels lock to lock 20 times, lower the vehicle and hook up a DRBIII or Starscan tool and manually make the hydraulic cooling fan kick on while briefly holding the throttle @ 3K RPM.
Not having a starscan or DRBIII tool to hook up to the OBDII, I went ahead and did all the steps up to the step where you hook up said equipment. From there I turned the A/C on, which sends more fluid to the Hydraulic fan and kicks it on higher, revved the engine on and off to 3K RPM(you will def. hear the fan kick up), turned the wheel lock to lock a couple times and there you have it. The PS system is now bled! Make sure to watch the fluid for the next couple days just to make sure there isn't any residual air that may bleed and lower the fluid level some.
Again this isn't word for word on install/removal/bleeding procedure but hopefully it helps some of you guys that would like to tackle the job yourself. Book time is 1.5 hours which I'm assuming is for a 2wd WK. All in all it took a little over 3 hours w/air tools and a girlfriend that doesn't mind getting dirty.
Fluid part number for the hydraulic fan setup is Mopar
