Front Axle End Seal

To my dismay, I discovered yesterday that my front axle is leaking diff oil from the driver side end. At 56,000 miles, I might add. POS.

Has anybody done this job themselves? Since I'm out of warranty, I'm pondering doing it. Wondering how big a job it is on a front, if it were the rear it's a pretty easy deal.

You have to disassemble the whole front end to include removing the carrier. The seals on the front axle go on from the inside of the pumpkin. Good luck on your project.

Looks like a PITA based on youtube videos. Not impossible, but wow.

Extremely aggravating considering it's something I shouldn't even have to think about for at least another 100K miles (or more). Guess I should be used to this pile letting me down by now.....

Come on Ford, release that damn Bronco.

Mine failed at less than 10,000km, then again at 40,000km... Just waiting for them to leak again. There is a reason I bought the 160,000km warranty...

Love my Jeep... but really... I don't.

The axle tube in the front is open to the elements so if you go mudding and the wrong pebble gets in the wrong area, your axle seal is gonna start leaking. As you noticed, its not exactly the easiest process to repair but its not impossible either. I almost did mine last fall but it was easier to take it in to the dealer and have them do it under warranty. Should take under 4 hours to do as a solo first timer.

What pisses me off in this scenario is the worst thing mine sees is the occasional muddy spring gravel roads and MN winters. Nothing I consider true off roading in the least.

It's like this damn thing has an annual issue, last year it was a leaky timing cover under 50K miles. Luckily, that one was covered two months before the warranty expired. And the rest of my coolant related issues, which were documented elsewhere here....and recalls.

Yes....I love my Jeep. But I hate it too. The hate is beginning to outweigh the love.

Many of you guys tolerate much more than I would. If this thing starts giving me constant issues, it's gone.

Oh, if the wife didn't currently have a car payment I'd be looking to move mine right now.....especially the way I feel about it today. I have no time for needy daily drivers that shouldn't be causing any expense and issues.....

I have a 52-year-old Mercury with 124K miles that has all the original axle components in place and STILL leak-free. And if I did need to change an axle seal in that, it's about a half hour job with beers.

When you change the front seals it's a perfect time to do the gears and /or a locker. You could remove the front DS and do the rears later. Just no 4x4 till you have them both done.

It's a common problem. We do all our work ourselves but are in the middle of a house remodel so I don't have time. I just called for quotes. To give you an idea 4Wheel Parts- which I NEVER recommend but I am desperate (wheeling soon) quoted me $300 in California. That's with a front air locker- $250 without I think. However while I was on hold with them I got to hear about their excellent Smittybuilt products for all your "off-roading needs" and I took it as a sign. I am going to a gear shop I trust- and he's charging me $400. I also have RCVs so I just want it done right. At home we figured a few hours for the work. But right now I have two missing toilets. Priorities.
Keep in mind a small leak can take a long time to make an impact. Mine's been leaking for probably 6 mos and fluid level is still fine. If you intend to keep your POS I'd strongly suggest replacing your diff cover with one that has a level check/magnetic dipstick at the top. It makes it super simple to check level and your fluid. They're not overly pricey and install time won't be any more than the stocker.

Lucas makes several oil stop leak products. For the front temp it might work for a while.

I have a slight seal leak on my front drivers side. My local Jeep dealer suggests replacing both front left and right seals since they have to take the front end apart. Their estimate is $600. Just thought I would share.

The dealer I bought mine from quoted me $793 for both. I figured while they're in there, might as well do both.

LOL. Not gonna happen at that price.

Yeah, my experience with other vehicles with leaky diffs has told me that it takes a long time to leak a significant amount of lube. So that'll give me time to gather parts and make myself some installation tools and prep for a fun Saturday.

Also pondering different diff covers....just not sure if I'll have this thing beyond another three or four years.

Keep in mind that the carrier requires a preload on each side of it. This means that even if you are able to pry it out of the housing you will most likely damage the shims re-installing it if you don't use a diff case spreader.

not impossible, Ive been in there twice to do it. 2nd time probably wasn't necessary as it was a VERY small leak. It is a PITA to get the actual seals in. I made a tool out of a long pc of allthread and several sets of washers and a harbor freight bearing install tool to get the correct size. also I believe a certain size socket fits perfectly into the bearing to help press. Took me a couple of seals to get the technique down...They are cheap, like $14 or so.

That said, for $300 or $400 if i had to do it again, starting from scratch, I'd take it in. 1st time was when I did the gears. If you were in tulsa I'd help you out.

Well, the plot thickens.....

I sent Jeep Customer Care a rant via email a couple of days ago, explaining the latest issue and the fact that it occurred at such low mileage. They actually opened up a case and I have to take it in for an official dealer diagnosis. As if I don't know what gear lube looks and smells like, but whatever. It's pretty obvious.

Should be interesting to see what, if anything, they do for me. I'm sure they pulled the service records by my VIN and saw what a PITA this thing has been since new and it may have a bearing as well as the mileage.

Or maybe it was the threat of trading it off on a new Ranger and wiping my hands clean that did it.....

I replaced the axle seals on my 2015 rubicon after replacing bearings and ball joints ended up compromising the driver's side seal. It wasn't a lot of fun, but it wasn't an impossible task either. I posted pics and video, but my hosting company is having issues with the photos right now. These vertical scope websites are a pain to find info on because they encourage posting a new thread for the same problems over and over again. It took me five minutes to find my own post with the info in it.

Ranger Raptor.....
CDJR dealers suck hairy orangutan balls. I can't believe I've still somehow managed to aquire a Ram and a Durango too.
That said- the couple of times I disagreed with dealers over items they said that weren't covered and I called customer service...I got it done. Good luck.

Well, Jeep is doing a goodwill repair on the driver side seal. Good news.

I'm on the hook for replacing the passenger side seal since it's not leaking, and replacing it makes sense while it's all apart. So, I'm just out $90 plus the hassle. Oh, and the cost to diagnose....

Props to Jeep for covering the majority, which I appreciate. But I still maintain that an axle seal should last the life of a vehicle if not in severe service....
