Autozone had a seal in stock, so I bought it and put it in.
The offending seal
Zapped off the nut with big bertha
Yoke slipped off with my fingers, very surprised!
Surface looks legit
Cleaned up the area
My favorite way to remove seals. Pound a hole in the seal with a screw driver and pry. Easy as pie.
Pull some fluid out of the diff with a syringe so it won't wet the seal surface.
Add sealer so it will lower the chances of a leak
Pound in seal. Always the hardest part it seams
Slide yoke on and douse the threads and back of the nut with sealer
Torque with the impact gun until it stops or until the rotational pinion torque is the same. In my case, it stopped (~250 FtLb from a 600 lb gun or so)
Now to add more fluid tomorrow when the sealer has set.
