    So I noticed on my rear driver side behind the wheel I could see fluid leaking.
    I took it into the Stealership, they said it was the axle seal. They replaced the axle seal. Now this week I could smell something burning. I looked under the truck same damn side is leaking. I took it into the dealership. They looked at it and stated that it's the inner axle seal? why didn't they catch this the first time or did they damage the inner axle seal taking my axle assembly apart so many times? I was told they'd cover this under a parts warranty, but now they're wanting to charge me 600 for it. I don't even care about the cost it's the time they've wasted. I've lost 4 days of work because of this.

    Around a week ago, the service manager stated to me that they can cover it under a parts warranty because they did not repair what was needed and it's still leaking.

    might wanna have them check the shoes and all that, any oil got on shoes they will need to be replaced as well. a lot of labor goes into doing this job. sucks they didnt catch it the first time, but you gonna be out another day or two.

    They said the brakes are good. I can tell you from my shit braking distance they're not and I'll be changing my brakes as soon as I get the truck back.
    Yeah I know it's labor intensive it's like a 10 dollar part and that's why I was not going to do it on this truck I was going to let the "professionals" do it.
    But clearly they screwed it up.
    They changed my outer axle seal the first time but it's still leaking. They said it's my inner axle seal now.
    If this was an old pickup I'd just cut the u bolts and unhook everything. Then change the whole axle but it's not so I'm here lol.

    Mine is leaking too. I'm about to pull both axles to replace them and the wheel bearings. First gens have a breather that can clog and push oil past the seals. Can that happen on y'alls?

    I don't have a damn clue I was hoping someone could tell me lol. I always thought you pull the axle off pull the old axle seal out and tap a new one on and out it back together.

    Exactly. This is a semi-floating axle. The design hasn't changed much over the years.

    This is your axle, per Toyota. You need #12

    Last time I was there that's what they supposedly changed. I was told my axle seal was changed.
    400. Now they're telling me it's an inner axle seal 900?
    I've been looking at that diagram all day and can't figure out wtf they're going to change Friday.

    I was going to comment on this at around 4pm today, just got wrapped up in other stuff. Sorry about that.

    So to add a little:

    Seals wear out, and with over 120K miles...maybe. Sometimes stuff just happens.

    Things to look out for:
    -If you run over on payload and tow a lot of weight, the bearing and race could be going south. I would change these out anyway while the axle is out. A simple press or NAPA can do this. I have changed a few in my days.
    -Look at your axle shaft for damage. This will continue to happen in the event the tech doesn't notice any issue where the bearing is pressed on. This is where the differences between a semi-floating axle and full floating axle really stand out between one another. On semi-floating axles, the weight is riding on the axle/bearing assembly that is pressed on. The full floating axle weight is all on the bearing hub assembly. Another reason I'm not for running over on payload. It will catch up to you (not saying this is your particular issue or accusing you of running overweight). When people need new spring packs/ over load springs/ airbags...a beer or two should be had and really think about what's going on.

    They're going to change your wallet weight. There is no inner axle seal. Your just getting charged twice for a job that should have been fixed the first time. This new quote is probably for new bearing/race this time.

    I could be wrong, and I would like for the dealership to prove me wrong.

    I appreciate it man.
    I've done bearings and races on my previous trucks and my trailers I run now.
    I don't ever overload it. But I do tow 5 to 6 times a week long distance.
    I'm going make a few comments to the service guys about that. That's a really good point I never thought about it till you mentioned it.
    I appreciate the info on the tundra axle I am not as familiar with this truck as i have been with my psst rigs. I'm at 157k miles btw.
    That's exactly what I'm thinking is going on.
    I would like the dealership to explain wtf an inner axle seal is.
    I usually do all my own maintenance and repairs but on this truck I just don't have the time or patience any more to do it. But in starting to think I should start doing my own repairs.

    I would sure be asking questions as well, and if anything but a credit to this repair bill isn't offered, a private mechanic or yourself should do this work.

    I'm definitely going to be asking questions. I just don't trust those clowns messing with my truck again. I really don't want the rear end to seize up on the highway at 3 am in the middle of nowhere. I'm hoping they do some sort of credit this is the only stealership I go to for service and I go in every 3 to 4 weeks for service. But I'm starting to question having this truck serviced at a stealership.

    I would do a couple things:

    1) get your paperwork from the 400.00 you spent, parts list, etc.
    2) Print out the diagram on the link I shared in post #9.
    3) Ask what they are going to do differently. I would be asking for a credit since the work done obviously didn't work. I believe when using the dealership and factory parts, there is a warranty on parts for 12 months.
    4) Have a backup plan for using another repair shop or yourself on Friday. In fact, I would be calling tomorrow to iron out this crap.

    I would also remind them you paid to have a service done, and it wasn't fixed. Period. I would also remind them that you visit this dealership every 3-4 weeks....

    Older tundras and tacomas had the inner seal but it looks like the 2016 Tundras only have one seal based on the chart posted by ColoradoTJ

    You wouldn't happen to have a diagram of that do you? If you don't have one up on another browser right now, I can look it up.

    I was totally planning on doing 1,2,3. 4 is a good idea I'm hoping they can fix it. If they can't I'm done going to the stealership.
    I appreciate all the help and info.

    I did rear rebuild on my 84 pickup and there was an inner seal from what i remember. I almost fd it up putting the axle back it as you have to be steady and keep the axle straight till you can bolt it up.

    Nothing has changed on these axles. The same diagram is for the 16' as well.

    Why would a mechanic change the axle shaft seal and not the axle housing seal while the axle shaft is removed? That is retarded and wonder if this is what is considered the "inner" axle seal?

    Yes that is my guess. I didnt know the terminology but thought there was one in axle housing and would have considered that the inner seal myself

    Ok the diagram shown in the link doesnt show all of the rear components. It shows the axle housing seal and not the axle shaft seal.

    So @BOBONTUESDAY, this should be interesting. Brian is right.

    This looks like an issue with swapping out the Axle shaft seal or "outer" seal, and not changing the axle housing seal or "inner" axle seal. For the life of me, I have no idea why the mechanic didn't change the "inner" axle housing seal first. This would be the first one to swap, since it's the one to stop gear lube from coming out of the axle housing.

    Now this is where to pay attention. If in fact they did swap out the inner seal and not the axle shaft seal, your bearings could be going south.

    If the dealership did only change out the axle shaft seal (which is retarded, no wonder your puking gear lube everywhere).
