What do I need to know before replacing my Steering gear box?

[zdbleam]

Hello all,

I know the gearbox is bad, and I want to replace it.

I've been looking around for more info on how to do it.
What special tools do I need. E.g. pitman arm puller

What should I replace along with it? (I'm already going to replace the pitman arm, idle arm, both tierods inner and outer) like are there any seals and whatnot.

What do I torque the bolts to?

Tips and tricks?

Any info would help

Thanks,
