    I took my stock 04' taco dc 4wd trd through clam beach creek last friday.
    It looked pretty much like the video below, but a wave of water did splash over the hood.

    My truck has 58k miles on it and I just had the diff fluid changed.
    Should I rechange the diff oil and/or anything else because of this water crossing? I will look at the idler pulley, and have checked the air intake. there was some moisture in the bottom of the air box, but the filter was dry. Immediatly after i power washed under to get the mud off.

    I will do the diff breather extension after this, but wonder if I should change the fluid.

    I have driven for around 700 miles after the water crossing and everything "seems fine".

    thanks for any advise.

    Changing the diff. fluid out definitely isn't going to hurt it. Plus it's such an easy job to do. But, a quick water crossing like that probably isn't going to hurt too much either. Changing the fluid might just be a good thing for "peace of mind." :)

    Definately change the diff fluid.

    While you're at it.... extend the diff breather so you won't get water in there the next time.

    Here's a link....

    When I did mine (on my previously owned 96), I routed the hose to the engine compartment. The front diff already has an extended breather on it - but I took that off and extended it further and *T'd* it into the hose from the rear diff.

    thanks for the replies.

    I am going to change the diff fluid and do the mod this weekend.

    I was thinking, is this a problem for guys that launch boats? I will be launching my boat with this truck and foresee getting the rear axle wet up to the diff breather.

    I wonder how much of a problem this is for folks launching boats.

    once you do this mod.........not a problem at all. for the most part....i think,depending on boat size and trailer.......the ass end of the truck isnt gonna see as much water as you would think, although, some ramps are different agnled, so its possible.

    With the angle of a boat ramp, to get the axle underwater you'll have to have water coming completely over the tailgate, in which case you're doing something wrong. The farthest I've ever seen anyone go in is just over the tailpipe.
    PS don't shut the engine off with the tailpipe under water...

    To make launching easier esp. at shallow ramps, consider entending the tongue on the trailer with a Fulton fold away coupler.
    http://www.etrailer.com/p-FHDPB330301.htm . I have the 3x4 model and a 36" galvanized extension and even at very shallow ramps my tires never touch the water. This is esp. important around salt water. Also the longer trailer tows better, is easier to back up and load/unload. Depending on weight you can also cut back on the trailer and add an extension giving you the ability to store your trailer indoors with the tongue folded.
