Basic 14bff oil seal question

[Mastiff]

I spotted oil coming out from my rear hub area. I haven't torn into it yet, but can someone bring me up to speed on what seal or seals is probably causing the problem? I assume the seal or seals is/are on the big assembly you pull off the axle housing? Thanks.

Is it leaking on the inside of the tire too? If not, then you just need the paper gasket behind the eight axle bolts. Just pull the eight bolts that you can see in this picture, pull the axle out, clean the area real good, put new seal on , or use RTV like most do, and bolt the axle back in. Easy.... I would jack that side of the axle up so that the oil runs to the other side of the rearend and doesn't leak when you pull the axle.

if you use rtv = vary little as it fills up the holes for the full floater flange bolts and will break the hubs over time.

i dont know how many times i see this . . . . striped threads or broken hub from to much trtv used over and over again and not 1 time did thay clean out the holes .

had to toss a few nice srw hubs cause threads all riped out and 1 cracked hub.

there is gaskets and few bucks for them also.

I always use RTV and I always use a pick to pull the "plug" out of the bottom of the threads every time. The bolts are about .5" too short to bottom out in the hub, so as long as you don't pack them with RTV 3 or 4 times without cleaning out in between, it's fine.

I've also had good luck with anaerobic sealant after my local driveline shop recommended it for that and the pinion support. It's a lot less messy than RTV, which is my only real complaint with RTV.

I use the Aviation sealant too. Works great and have not had a leak to date.

RTV isn't messy if you don't gob it on like you're trying to seal up the holes in the Titanic...

A light coating on the hub, a light coating on the axle flange, just a coating, when you tighten them down, they seal together, no gushing out, no mess and easy to clean off with a wire brush when they are taken off again.
