Here is the end state of my rear diff. Unless someone yells nooooooooo, I'm done.
Nooooooooo! Why did you pick yellow as the color to paint your gears???? Everyone knows drivetrain components are supposed to be painted red! Back to the sanding cabinet Charles and clean up those parts. Might be a good time to get them galvanized like every part of your truck anyway!
Just in case someone reads this and mistakenly thinks that FTC4939G is the correct seal for the pinion on a diff, it's not. And hopefully they don't destroy two of them before going inside and looking up the part number to see they just destroyed their LT230 output shaft seals and should have been using a FTC5258 instead. Even better if they avoid spending an hour getting setup to put the damn diff in their press and then pressing a FTC4939G in and noting that it still kinked like the first one
