Replacing seal on steering gear

[Asshat]

Have you guys done this while the steering gear is on the truck? Or, do you guys take it off?
It is probably a little difficult to get at it while laying on a creeper.

I take them off.

Can anyone tell me which seal goes in first? One seal is thicker than the other.

This is the guide I used, from Tx Firefighter

The order from outside in is snap ring, flat washer, thick seal, washer, thin seal.

I came to the conclusion that my input shaft is leaking, not the pitman arm shaft. I read in this post below, it is possible to replace the input shaft seal without disassembling the entire gear. Is this true?

The procedure for replacing the seals without disassembling the entire gear is in the guide from Tx Firefighter that I gave the link to.

The most common leak point is the o-ring on the adjuster plug and not the input seal.

While I knew guys that would replace that o-ring on the truck, I always felt better doing it on the bench. There's a few important steps that have to be done just right for the box to work properly again.

I removed the steering gear since I could tell it was leaking at the input shaft seal. Hopefully, the seal kit I get will work.
