    A 'Thunk' is good!

    The ADD improves gas mileage, reduces wear on parts when you are in 2WD... think of it as automatic locking hubs, but better in that you can shift on-the-fly (no driving in reverse to unlock) into and out of H4.

    I only heard of Auto. locking hubs that needed to be driven in reverse to unlock... since then ADD was created. I wonder how it unlocks at the hubs without driving backwards?

    Thanks Christian... The ADD does reduce wear compared to staying locked all the time, right?

    Neither did my First Gen (2001) Tacoma... it also had an ADD (shift on-the-fly 4WD)

    I never said ADD did... when I said 'it', I was refering to the system Christian was describing that wasn't an ADD.

    If 'it' doesn't need to be driven backwards and 'it' isn't auto. locking hubs... what is 'it'?

    I think what Christian posted just above may explain it. But, is Ford really so bad at making an ADD that they have 4WD trucks running in 2WD with all the front end moving?

    Thanks for offering to help!:D
