Nissan Repair: 87 Pathfinder 6cyl 4x4 power steering gear box, power steering, pulley

Question
How do I rebuild a leaking power steering gear box, it's leaking from the bottom of the box, can I get the seals and do I need a press to replace them  

Answer
Andy,

You need a puller to get the pulley off and the internal bearings require a press to remove them.  If you have not done it before I would take it to a shop with a press and let them do the heavy work.  I bought a press since I was tired of the price of press work.
