Check my thinking - 915 trans output shaft seals
 

I have one output shaft seal that is leaking and slinging fluid. Please check my thinking on this. I'm going to reference Grady's write-up and a few others:

My thought process for the big gotchas:

- Replace both output flange seals while I'm in there.

- Do one side complete at a time (don't take both CV joints off) so I don't have to fight with holding one flange while removing/reinstalling the center flange bolt.

- Use the factory seals.

- Check inserted depth before removing.

- Make some insertion tools (maybe that 3D printer is really useful for something...)

- Inspect the output flange shafts for grooving/wear before reinstalling.

- Center flange bolt gets torqued to 20 lbf.ft. on reassembly.

- New Schnorr washers for the CV joints; maybe check the grease fill before reassembly.

Are there any other tips/tricks that I'm missing?

Thanks for the help.
