Ole4Cyli Yesterday I drove out to the beach, did some sand wheeling, then drove back. No problems with the fluid! Just the same slow leak from the old water/oil mixture. In a couple hundred miles I'll change out the fluids again just to flush it all out. Thanks for all the help guys!

If its still coming from the tubes its probably just excess or a major problem if some sort lol its hard to tell if your seals are bad without filling it back up with fluid. If it still leaks catch all the fluid in a clean pan and re use. No need to waste it

Jeepfixer1 Sorry, just saw! Yes as said brake clean due to fast evaporation but carb should also work.

Brake clean evaporates very quickly. Just spray it and let it sit for a couple minutes

Drive it and see what happens. Wish you luck!

Ole4Cyli I just took off the front diff plug to see, fluid was a mix of black and tan in color, and it poured out on the hole, that just means I need to change the fluid, correct?
06-12-2013 05:45 PM
freeskier If there is water in it don't drive it. Check to make sure your breather tube isn't clogged and replace the oil. If it stops leaking then great! If not replace the seals. You can also catch and reuse the oil if you have to do the seals, no need to throw away new oil.
06-12-2013 04:36 PM
Ole4Cyli I think it's just that I got water in there. I say this because this morning I went to check on it, and it's started leaking from the other side as well.

Make sure when you pull the cover that you mark those caps with a punch so you put them back like they came apart and if there is any shims. That they go back like the came out too. On a 1-10 scale with ten being the hardest then I would rate this a 7/8 with you not having done it before.
I got all summer and a bunch of redneck friends. I think I'll go for it myself. Thanks for the help!

Jeepfixer1 That's a good write up but like a tv show kinda makes it sound like it can be done in 30 min. But It also has the two most important torque values too!

Thanks! This is really helpful!

This is the guide I used when changing mine. It's not that bad. You have more experience than I had when I changed mine lol I tore mine up trying to install a locker that I ended up having to install 3 times.

Jeepfixer1 Those outer seals are to keep dirt and mud out of the tube. They would work on helping keep the water out but aren't really designed to fix a leaking axle seal but if you are worried about doing that job yourself the outer tube seal might help buy you some time.

When I did mine the seal was $10 I think. Gear oil was the most expensive thing. I bought some thicker too to help silence my Aussie locker. And then some bottles if brake clean. Should be under 100 unless you do the outer seals.

Had a friend use these. Still have to pull the diff cover but the carrier can stay. Axle shafts have to come out. Also more expensive than the OEM inner seal

Would it hurt it to drive around as long as there's still enough fluid in the diff?

Dammit, so it's no seal that's closer to the end on the axle? Oh well, probably a good time to change out the diff fluid anyways.
