    Nope I just feel that It's a new truck let me have 36k before crap like this happens. Maybe your don't care, that's your opinion, everyone else who feels that quality should be better has there own opinion.

    I didn't buy a used truck, did you? Obviously 40-50k is chump change for you.

    I just checked and mine is seeping as others have posted. I have just under 25k miles. I’m taking my truck in for the last Toyota care service so I will see if I can get them to do something about it.

    No, it's not chump change and never suggested that it was. What I am saying is that you could probably drive your Tundra 150k miles and NEVER have an issue with that tiny amount of seepage. I do not think that Toyota intentionally caused this issue but I am confident that they will correct it. Thus, I am NOT worried about it. When my 4Runner began developing cracks in the dash at 100k miles, Toyota replaced my entire dash free of charge. That's something that I know damned well Ford, Chevy, Dodge would NEVER do. So, I love my Tundra and I love Toyota. Maybe you'd be happier in a Nissan?

    again let me repeat you may not care about the seepage but I do it's a new vehicle it should last longer than that before it starts seeping. I don't care if it can run until 300,000 miles but that's not the point, the point is this shouldn't be occurring in the first place. I'm sure if your cam tower started leaking you would be complaining about it too or is it just a leak?

    tell that to all the people petition against the camp tower leak. It's just a leak and you drive it without any issues right

    Well, my cam tower might start leaking and it might not. My Tundra might also be hit by an asteroid, or it might not. But I'm not going to worry about it. I know that Toyota will take care of any cam tower leak should that occur, as again, I don't think they intentionally planned that to happen. Oh, and I understand your "point". But, I'm not worried about that either. As for the new trucks on the lot not having the seepage: maybe they resolved the problem (which would make your anger on this issue moot); maybe the new ones on the lot require a few thousand miles for the issue to appear. Again, I am NOT WORRIED ABOUT IT. In fact, I would happily purchase a new 2019 Tundra with the current knowledge that a diff seepage and/or cam tower leak might occur. I say this because I love the Tundra and have confidence that Toyota will repair these issues if they become issues. I would NEVER say that about the competition. I've owned GM, Ford and Nissan and have had ridiculous issues with all three. I will reiterate to you: Maybe you will be happier in a Nissan.

    I took mine in for 25,000 oil change and mentioned the leak. I had to actually go back there and point it out on the rear diff because they “couldn’t see it” :rolleyes:

    should a new(er) car seep?
    NO

    However, some seeps can eventually stop (I've seen that in older cars) and some very minor seeps will not cause any issues for many many years ...

    If you think you can live with that and don't want the risk of fixing it, at least take it to the dealer before the warranty is over and document the leak. In that case if it got real bad you can ask them to fix it later.

    I've noticed that some repairs are with sealant and mine was repaired by replacing the gasket? I personally think replacing the gasket is the correct way to repair this. What do you think? Would you be satisfied with a sealant repair?

    and? So we are saying Toyota has seepage is acceptable if someone owns it and drive sit off the lot? My problem is not that its seeping, it's that the Toyota dealership i went just wants to keep an eye on it despite it being very obviously there's multiple points of seepage in the rear and front between bolts.


    This is like buying a new home and say it's okay that your toilet ring leaks onto your nice hardwood floor or your new roof has a small leak and the mfg says it's OK we'll just keep an eye on it.. That's Unacceptable.


    I will wait for Toyota to call me back and we'll figure it out.

    Well, I do not think that is a very good analogy. My diff seepage is not "ruining" anything like a "nice hardwood floor". In fact, it's not ruining ANYTHING at all. And when you say that it is "unacceptable", what exactly do you mean? Are you saying that you want to return your Tundra for a full money back refund? Are you saying you want to blow it up? Are you saying that the engineers at Toyota should be killed for their incompetence? Sheesh! Get the damned thing fixed and move on with your life already! If you don't want your truck, sell it already! Otherwise, your truck will be fine. You will be fine.... well, unless you have a heart attack from raging over what is acceptable and unacceptable. Look, you've purchased a damned nice truck. Yes, it sucks that it cannot be an absolutely perfect, flawless gem of a machine. But that's why they give you a warranty. So relax, Toyota will take care of it. BTW, you still have not responded my suggestion that you possibly switch to a Nissan. What gives?

    Yes, you said that. But you also said it was "unacceptable".... hence the confusion. And no, I've done my time with Nissans. Never again. Maybe your beef is with your crappy local dealership. My closest dealership is pile of shit too. But I do not blame Toyota for that. Luckily, I found a much better one not too much further away.

    I can see it both ways. I can understand being pissed a new truck has issues. Service told me my cam shaft leak on the driver's side was enough to fix and offered to do both sides. I'm at 6000 miles. I'm not going to fix it unless it becomes more significant or it's bad enough to fix at the end of warranty.

    My rear diff is also seeping. Same service manager told me not to worry about it. If/when it gets worse, I'll fix it. I'm not going to worry about it now.

    Should this stuff leak and seep? No. But I believe if it wasn't for the forums, the smaller stuff would go unnoticed with little impact on the reliability or longevity of the Tundra. A lot of warranty work has come from threads like this. There were six guests reading this thread.

    Anyone else getting fluid weeping from the breather also? You can see a little leaking on this side of the diff. The other side is worse.

    Haven't read the whole thread, but is anyone's diff actually leaking? All I've seen in the pictures posted is a bit of staining from perhaps a drop and a half of gear oil. Its like some people think the underside of a vehicle should be polished.

    Some members' seepage is worse than others, but no, I have not seen or heard of any, on this thread anyway, that are actually dripping on the driveway. Just some "wet spot" seepage on the diff case. A mechanic buddy of mine (whom works on cars for a living) told me that its very possible that the type of gasket used by Toyota, could have simply soaked up oil to the point of minor seepage, until a point where the gasket swells and thus seals the mated diff casing, preventing any further seepage from occurring. It's just a theory, but he said he has seen this before. Regardless, he took a look at mine and said "don't worry about it unless you see it dripping".

    It’s like 120,000 degrees here in Vegas, no salt obviously and mine appears to be worse than everyone I’ve seen here. I’m thinking the heat helps with the lower viscosity so more seepage ?

    I'm in southern AZ... same. I also tow a 6,000 lb boat and trailer regularly. I'm sure that does not help. Coincidently I just changed the fluid in my front and rear diffs before seeing this thread.

    I agree asking the dealer to fix it might cause more harm than putting fresh oil to the correct level every 30-50k. It appears to seep pretty good but does not drip.

    Toyota recalled 225,000 Tacoma’s last year for this exact “staining” on the rear differential. None of the ones I saw involved in the recall were dripping on the ground yet Toyota stated it was a catastrophic failing part and started to replaced the gaskets.
    Oil should be an internal lubrication not an external display of artistry.
