    How difficult is it to swap gears in differentials while they are still under the rig? (14 bolt FF and D60)

    I have a friend with a 1-ton Crew Cab and we just discovered today he has 4.56 gears in it. I have 4.10's in mine. He's only going to run about a 34" tall tire and I'm going to run 44" tires; so I offered a trade of my 4.10 gears for his 4.56's.

    I figured it'd be easier to swap out the whole differentials, but I don't think he wants to do that.

    That would be labor intensive.
    If you haven't set up gears, i would highly recommend against this. Honestly, even if you have done a hundred sets I would still say no.
    Swap out entire axles if you want to do that.

    By"swapping differentials", I assume you are talking about carriers. That wouldn't make any real difference in the labor. Only thing it would save you is bolting/unbolting the ring gears. You still have to set the gears up. And if you haven't done it before, it is labor intensive and requires some specil tools. However, it can be done. I did mine myself and I consider myself shadetree.

    Swapping axles may be the easiest way to do this for both, but hat depends on the application of course.

    I agree, I swapped axles to get my 4.56's.

    I'd gear lower, but... It shouldn't be too bad, but you'll NEVER get them to mesh up like they originally were. They'll wear down a lot faster. I'd swap entire axles with him.

    <font color="green"> I'm gonna agree that you should swap the entire axles. It would be a hell of a lot easier on both of you. Setting up 4 R&amp;Ps is a daunting task. The 14 bolts are pretty easy, but the 60s take some time. Just let him drive around on the 4.56s with 34s for awhile, he'll want to swap pretty quick... /forums/images/graemlins/smirk.gif </font color>

    Yeah, I figure swapping whole axles would be easier. (thats what I intended to mean by "differentials"). I'll just offer to do the swap with him...I'll even do all the work myself. It's worth it to me to get 4.56's, and he should get more what he wants for mileage.

    I agree with the full axle swap thing. If $$ allows, I recommed putting in all new u-bolts at the same time. If you do this, then cut off the old ones with a grinder or cutting torch. This in itself will same enought time, making the expense of the u-bolts worth it.

    I'm gonna be pulling the 6" lift out of my Crew Cab anyway and putting a 12" under it, so I have different U-bolts. And it happens that he just put a 4" lift under his crew cab, so the U-bolts are brand new. Hasnt even been on the road yet. It should make life a bit easier if I do the swap. /forums/images/graemlins/smile.gif
