1997 Jeep Wrangler Steering Gear

Steering problem
1997 Jeep Wrangler 6 cyl Four Wheel Drive Manual 110K miles

Well my friend has 3 wranglers, 1-94 which is ok. He also has a 97 Sport which has a 2yr old sticky gear, and a 97 Sahara with a leaky gear. So he got a new gear for the Sahara and I pulled the old one apart to fix the leak in bottom so I could put it on the Sport, but I accidently leaned on the pitman arm and the piston came out. How can I get some info on how to reset the brgs in the worm gear. I have tools to hold stuff like that in place. But only if I know how the primary setup is. Can you help?
