Finally got her dun .....here is what ya need
seal kit...I used a edelmann part.....or you can use GM 26053277
ring kit ...GM 26046606
small screw driver.....sharpened
punch... 3/32

22 mm wrench or socket

much kudos to PSC Motorsports in Azle TX for allowing me to pick their brains to find out how to do this as I know of no manual available for repair ( and neither did PSC ) , they do all steering systems for any car or truck but specialize in 4x4 stuff...hit em up if ya need em

first step....remove resevoir....to do that ya gotta get the clips off
I used a hook from a pick and hook tool kit
lift up on the inner tab and punch the other side of the edge of the clip with a screwdriver to push the clip off...if ya got a friend to help MUCH easier
pull off the reservoir and notice how bad the O ring is ....leak city !!!

next step ...get the ring retainer out of the back cover
there is a small hole on the bottom of the pump ...use the 3/32 punch to dislodge it out of the recess

the back cover does not just pop off....use a rubber mallet to hit the the end of the shaft to push the cover out and off
not to hard or you will send it across the room !
