    Default 14 Bolt 3rd member swap Q

    I have a 84 dually that PO swapped the 4.56 gear for he said a 3.54, but I'm thinking after a tow the other day its even higher. My Q is, I have a Military single 14 bolt with 4.56 (should be), are they the same 3rd member? Also, if memory serves, can't I just pull 3rd member n not have to setup gears PO at same time of gear swap had shop put a NV4500 n, so I don't see any prop with highway running at 80? anyone running 4500 with 4.56 on 265/75s 5th at present is pretty much worthless, truck has 6.2L with banks kit.

    thanks,

    I know, its a carrier, not a 3rd member, but still, no one going to say anything ???

    I am not an expert on setting up gears, but I know that you will need to swap out both the ring gear and the pinion gear to change gear ratios (ring and pinion are considered a matched set and should always be changed together, if my understanding is correct). I don't see any way, even using used parts, to change the gear ratio without going through the process of setting up the gears.

    You will definitely have to re-set the gears.
