    I wonder what happened in 2018?
    Seems like it started in 2016/17 same time the Tacoma rear diff got recalled. Bad gaskets being manufactured for Toyota? Robot not set to torque properly? Sabotage :eek:
    It’s going to be interesting to see how many 2019’s leak as they get more miles on them and how many 2020’s. Seems like most notice it between 10-15k miles.
    Thank you to everyone that has participated. :thumbsup:

    It will only let me add 2020 leak. It taps out at 20 options.
    I guess we don’t really need to know if none of them leak just ones that do :notsure:

    I can’t edit the poll questions or remove any that are already there. Hopefully no one with the 2020 has any issues. :thumbsup:

    That's the same story for me...2018 and about the same mileage. The dealership replaced the gasket on my rear diff. Good luck with the repair.

    I went into the dealership with pictures and spoke with the service rep. I told it was under warranty and that he needed to order a new gasket and then we scheduled the appointment a few days later when the parts came in. In a way, I 'prepped the battlefield'. I dropped the truck off a couple days later for the repair and talked my way into a free loaner.

    A glob of grease on the U joint isn’t bad. They are designed to be greased to the point where grease oozes out of the caps. The glob probably means someone didn’t wipe it up after the service. I get a small amount of sling because it is a hard area to clean after packing them with grease.

    First it's OK for a differential to gush fluid and now it's OK for u-joints to leak grease. This Toyota fanboy apologist stuff is going too far. I just got back from a 1200 mile trip towing a side-by-side in humid 90 degree heat and noticed water dripping from up front near one of the a-arms at every stop. I suppose that's OK too?

    I can't figure out if this is sarcasm... Are you really concerned about some water dripping from the engine compartment on a hot humid day?

    yep, I'm almost sure it is A/C condensation.
    All cars running the a/c in 90o heat will do that.

    This thing's leaking from every orifice. For God's sake, it's a Toyota, not a sorority girl doing the walk of shame home on a Saturday morning!

    Be mad at Spicer for making their U joint the way it’s designed. When you pack them with grease, you’re supposed to pump it until you see it come out from under the caps. Been this way on all my trucks with serviceable U joints. If you’re not servicing them and they are leaking an ungodly amount, maybe you have a problem. Otherwise it’s just the nature of a serviceable U joint. Nothing apologetic or fanboy about it.

    If you’re running your air conditioner it has a drain for the condensation, that drips out just above the lower A arm.

    I’ve never heard about anybody having a “gush”of fluid from their differential. I’ve heard of some leaking, but no “gush”. Which I agree with you, that shouldn’t be happening, no matter how slight it is. After 5-10 years....maybe.

    Btw. You are on a Toyoya forum. Most of us tend to like our trucks. It’s to be expected that some will make an excuse for issues, or get sarcastic with you. I’m not giving you an excuse, just the facts.

    Well I was told it’s normal if seeping from the inside where the bolts are, abnormal if you see it leaking from the back of the truck. :notsure:

    Seems some get it fixed and some do not. Perhaps if folks bring papers of other folks fixing it. Dealers will listen.
