    Truck got caught in a flood and i am 90% sure the water was above both differentials. Going to go ahead an drain and refill both differentials. Appears to me that the TCase and the transmission should be fine. Wondering if I will need to do the drain and refill the diffs a couple times of if once will be sufficient?

    I pulled fill plug on rear and oil looked OK but was overfilled and maybe 1/2 qt-1 qt drained out so I am guessing that overfill is from water coming in through the vent

    Only other issue I see if possibly the alternator being so low and maybe having it fail later on

    If you have insurance, I wouldn't do anything until you call them and see if they want to send out an adjuster. Just my 2 cents!

    Even if it was flooded above the differentials, it does not mean that they are filled with water. Only a small amount, if any, would enter the differential, so I would say one oil change would suffice. If you drain the oil and it is obvious that there is a lot of water in there then a second oil change might be justified, but I doubt that.
    Check for other components like the alternator - if it is apparent that it got flooded also then maybe get your insurance to look at it.

    I had my Tacoma in some pretty deep water (middle way of the doors) during a hurricane we had here in NC several years ago. The differentials were to totally fine. Water didn’t even get inside the truck when this happened either. I was shocked honestly. Now the tundra might be different so take this info how ever you like.

    insurance has already been involved and I will be "salvaging" the truck. Unfortunately it was saltwater, which I am sure will cause some issue later on.

    The rear oil looked clean when I opened up fill plug but was overfilled which I am guessing indicates water? I assume the water has probably settled to the bottom. I am going to go pick up enough gear oil for front and rear and go ahead swap out.

    Ill keep yall updated

    Yes, salt water adds to the concern for sure.

    Isn't the front diff and transfer case breathers mounted up high on the firewall? I bet the front is ok, and unless you have relocated the rear diff breather, you have water in there. I would start spraying everything down with water displacement spray, and start relubricating everything underneath the truck. Especially the brakes, and any wiring connections.

    Good luck!!

    When I drained the rear I didn’t see any indication of water.
    Haven’t checked front or transfer case yet

    Yeah, front breathers are higher up in the engine bay. Did you also hose it off really good underneath? We have long winters here and I go to the car wash at least every 2 weeks to get the salt build up off.
