How To Replace Inner Axle Seals 

front doesnt see much gear wear when your mostly free wheeling in 2wd

Yea I have a rusty 01 Wrangler as my first vehicle and it's all fun and games until u get a bolt that's stuck.

Not too good, water likes to get trapped inside the axle tube.

The Dana 30 and Dana 44 axles are almost identical. They use the same axle U-joints, ball joints, and Knuckles. The only major difference is the gear size. I would just make sure when you are removing the ring gear, make sure to install it same way. It should come out all is One Piece like what is shown in the video.

Right there with you. It is probably about time to do this on my 96 XJ with 337k miles.

That's what happens when you work on cars over 200k

Joe Robinson heck yeah this guy made it look easy, big job but I think I’ll tackle it this weekend

Cfass1 There is a lip in the axle tube where they bottom out and you'll know when you hit it.

You will feel them bottom out.

Ryan, these outer "seals" are great, but they only are there to keep dirt and mud and anything else out of the axle shaft. If differential fluid is leaking out to there, the inner needs to be replaced. I like those outer for that, but if you have a leak on the inner, your diff will be toast if the outer holds in the fluid and you don't see it, there's not enough to fill the axle and keep that diff full. If you have fluid coming out, the inner seals have to be replaced, in my experience.

@@jasonmalmquist7889 thx Most of time my vent tube gets clogged from going down dirt roads everyday and it starts seeping past outer seal or pinion seal due to pressure buildup but once i clear vent tube it stops leaking. My vent tube bolt thing is stripped so it comes out of axle and sometimes water and dirt get in and screw up seals. Thats y i change em so often. I need 2 quit being lazy and remove axle and tap tht hole but hey what can i say. F it

I use inner axle seals made for a 2001 Jeep Cherokee front axle Dana 30. Easy to source on rock auto. Outer axle seals are aftermarket and ones I used are made by Ten Factory.

You can take the axle apart and clean them out. Pull the shafts out and pop out the carrier. I would recommend replacing the inner seal like what's in the video. Then you can stuff a rag in the tubes and push it through to clean them out. Outer seals I got were by 10 Factory: www.amazon.com/Ten-Factory-MG21102-Dana-Axle/dp/B005TDN2KI/ref=sr_1_5?crid=2TQKU0A5SBIZF&keywords=jeep+dana+30+outer+axle+tube+seal&qid=1652303579&sprefix=jeep+dana+30+outer+%2Caps%2C110&sr=8-5

That's the risk that you will end up taking. You won't know unless you pull the axle tubes or check the diff level on a maintenance schedule.

@@OutJeeping Oh ok thats true, I'll be adding that to my maintenance then. Thanks again man.

Yeah I would check out the axle shaft surfaces and vent lines on that one.

Lol

You can if you want to, I opted not to and have had no leaks thus far.

Any RTV should work but they make differential RTV or RTV for sealing against oil, that would be best. As far as shims, with the Dana 30 model I have in the video, the shims are pressed between the bearings and the carrier, so they didn't pop out when removing the carrier. On other axles you may have the shims pop out with the carrier because they get installed on the outside of the bearings. If that is the case then yes, make sure to install them back to the same sides that they came from.

At most auto parts store they can be rented.

Pretty much, on a Dana 30 axle I showed in the video the shims were pressed in between the carrier bearing and the carrier so I didn't have to worry about them falling out on this install.

As long as it's a non front axle disconnect axle. It will be a bit different on the passenger side if it has fad.

The shims are there but they are between the carrier and carrier bearings.

Thanks, I think i used 75w-140 but all depends what climate you live in.

I run 80w-90.

I would start them by hand with a small hammer to get them in square and being careful not to damage them. Then move up to a larger hammer with a seal driver or socket to hammer it in the rest of the way.

@@OutJeeping thank you just picked up a few projects and this was first on the list, really appreciate your videos

Yep that is the downside to outer axle seals.

For the most part yes

On some axles the shims are between the carrier bearing and the axle housing, for this axle the bearings were pressed in between the carrier bearing and the carrier.

I went with "Ten Factory" accessing the zerk fitting is a little bit tight.

It took about 4 hours. The CV axles will fit but they are not as strong as a u-joint

thank you

The outsides of the axle shafts use the hubs/unit bearings as their bearing and then the inside slides into the carrier which has bearings also.

BAWLS2894 About 4-5 hours but that was with filming so probably less.

It took me a day and a half total. I didn’t really know what I was doing the first day. The first half day I didn’t realize I had to take the carrier out of the differential I thought I only had to take out one axle at a time. It wasn’t until I saw this video the next day that I knew what I had to do. So I’d give it a full day if you haven’t done it before.
