Eaton e-locker leak

Ya I'll go shop tomorrow, however I would like to know what would have started my problem an solution . My rear end is leaking fluid where the electrical wire enters the rear end housing for my eaton e-locker. Just started, I used it several times while in Wyoming an when we got back , clean trucks bottom an zero oil/ grease showing at that time .I've only driven truck 50 miles,at most,since then . Any ideas . Is that plug just a simple screw in. An held in with rubber o-rings??

 

If it's leaking at the drilled grommet hole, mine seeped occasionally, try cleaning the crap out of it and I mean get it really clean, then get some 3M 5200 marine sealant and apply a thin bead around the grommet. If the grommet is toast order and replace. Also you can try "venting" the axle assembly that cured mine completely on our first Tundra build.

 

Thanks ,ya mines vented to taillight housing for when an yes water crossing!

 

I’ve had mine installed for a couple years, as soon as I got home from the install I put a bead of silicone around it for piece of mind and it hasn’t leaked at all

 

Thanks

 

Ya silicone was shot thanks
