Torque Tube Seal

[CA Victoria]

I have removed the torque tube bearing sleeve and now need to replace the lip seal in a 37 axle. I over looked this while the axle was out and disassembled.
I read that the seal comes out the front but it looks like there is a lip or snap ring to prevent it from coming out the front.
The two diagrams I have suggest it comes out the front.
Any tips on R/R this seal would be appreciated.
Thanks for weighing in.......
