The easiest way is also the messiest.
Remove pit-man arm nut,Mark the pit-man arm and shaft with a colored marker,to assure you reinstall the arm in the correct position.use a pit-man arm puller to remove pi-man arm.When you get off the shaft,swing it out of your way,leaving the other end connected.Looking up in the steering box you will see a snap ring that you need to remove.When you get it out of there,reinstall the pit-man arm and nut to the correct position but don't tighten completely.Now refill the power steering box with fluid and put the cap back on the steering box.Put a pan under the pitman arm to catch the fluid.Start the engine and turn the steering in one direction as sharp as it will go,you'll here it in a bind but hold it tight,Then turn the steering wheel the complete opposite direction and turn it tight.This will use the power steering to blow the seals out!
Shut engine off,look under car and your seals will be pushed out but held in place by the pitman arm you reinstalled.Now you can remove the arm and REMEMBER how they came out,just incase there is no picture instruction with your new seal kit.
