Power Steering gear box problem - Help!

[finall]

Great. Thanks for the photo of the steering box. Yup, mine is definitely missing something. Is the dealer wrong telling me that everything is normal?

Did some more checking with the dealer's parts dept. There is a dust seal that appaears to be missing!! Unless it recesses fully into the steering box bore, which I doubt. Looks like maybe Part #27 in the attached diagram.

I got a call into the H2 certified GM Dealer (only H2 dealer for 600 miles in the area), and I am just waiting for them to call me back and explain.

Hi George, i tried to find that diagram. Here is what those part # are. Also that is for sure #26 sitting on the shaft not in the bore where it belongs. That dealer is full of chit. Number #27 is missing likely because someone did a sector shaft seal kit in your truck to fix a leak before and #27 never got reinstalled. The old one was likely garbage and didn't get reinstalled and #27 never used to come in the sector seal kit from GM. Even if that is not the snap ring sitting on top of the dust seal it still should be up in the bore and the foam peice should be there. Hope this helps.

28- pitman arm
27- foam or rubber seal to protect the seals and shaft from dirt {missing on yours}
26- dust seal that is to be inside the bore {yours is sitting on the shaft}
25- snap ring {that maybe sitting on top of the dust shield on yours its very hard for me to tell in your picture}
24- washer
23- Main hyd seal {yours looks in the picture to have moved down because i think the snap ring is not in the grove, but its hard to tell in the picture, this is also why i said it could be dangous if the snap ring has poped out of its grove and their is only a press fit holding the main hyd seal in the bore.}
22- bearing
