    I am going off topic a little here but the concern has been raised that many trucks are being delivered to you guys without a single drop of grease in your new driveline , low oil in the differentials and low oil in the transfer case and last but not least , under torqued u-bolts holding your rear axle stable .
    The factory grease in your universal joints is only an assembly lube . Your driveline needs to be lubricated at every oil change . Make sure they greased your driveline when they sold you the truck . There will be traces of fresh grease on the universal joints
    Read what Spicer has to say about greasing your driveline . I am certain that Spicer still has the Toyota contract . They make all your driveshafts

    If you cant see any grease zerks , you've got polypropylene universal joints . They are designed for 50,000 trouble free miles according to the seminars I have trained at .Here is a new write up with some 2016 trucks involved
    https://www.tacomaworld.com/threads/check-your-u-joints.409042/page-2#post-11509086
    If you do not own a grease gun , go buy one because you are going to need it
    If you have a two piece driveshaft , reports are coming in there is a lack of lubricant on the splines of the slip and stub . Your truck will clunk when downshifting into first gear when cold . Takes a special lubricant

    I think that this thread is supposed to be specific to 2005+ units, correct? You may want to check over some of those links, which apply only to <=2004.

    I.e., Superduty transmission mount, also the 2-low mod (that mod will freak out the 4wd ecu before you can get it in low). There are a couple of different 2-low mods for 2005+ that work, that one just isn't one of them.

    This is the 2-low mod I favor; http://www.yotatech.com/f117/2wd-low-done-right-280421/
    (benefit being that it maintains correct inputs to all ECUs, nothing freaks out, no warnings on the dash.)

    Also, very nicely implemented "yellow wire mod": http://www.yotatech.com/f117/4l-trac-done-right-280412/
