    Welcome to TW!

    The axle code for your rig can be found on the manufacture's sticker located on the driver's side door jamb as follows:

    First digit:
    • A = 7.5" ring gear
    • B = 8" ring gear
    Next two digits:
    • 01 = 3:42
    • 02 = 3:58
    • 03 = 4:10
    • 04 = 4:56
    • 05 = 3:15
    • 06 = 3:91
    • 07 = 4.30
    Last digit:
    • A = 2 Pinion, Open
    • B = 4 Pinion, Open
    • C = 2 Pinion OEM Limited Slip

    4.10 gears and the V6 with 33" tires is already marginal - some people are fine with it, and others feel like it is too low (particularly if they live in the mountains). If you were going to tub out your fenders and go with 35s or 36s, you should definitely look into regearing - I don't think most people would be happy running that high of a ratio on those tires.

    To have someone else do it, between $500 and $700 per axel.

    Its not hard. You just have to set the back lash correctly.

    So what gears would you go to with, let's say, 35's stuff under the truck? Ideally?

    Depends on if you want to be near stock, or a little over geared. Figure out how much larger percentage wise, the tires you are running are, then add that percentage to the stock gears, and round up or down.

    The general consensus at TTORA would seem to be 4.88 with 33's and 5.29's with 35's, but thats with an auto trans. Not sure about a manual. I'd guess a step lower since the auto can get away with it a little easier. Take into consideration that they're much more into rock crawling than most of us are as well.

    But, of course, as Chris4x4 said, it really depends what you want to do with the truck and how/what you drive on.

    For me, I'm still running 4.10's on 31's (265/75R16) and I feel like theres some spots that are really lacking in power, specially on decent inclines. 99.9% is just fine, but its just those rare times that I'm heading up the canyons or something when I wish it was a bit more.

    Another resource is you can take a look at the bottom of the tire size calculator to get a better idea of what you can expect. I believe factory tires were approx 245/75R16. 33's are approx 255/85R16, and 35's are close to 315/75R16. So, with 33's, you're looking like you're bare minimum for the 4.10 gears, with 4.56 being close to stock. With 35's, you'd be way under powered. Personally, its a bit silly to only do a single step up on gears, so I'd either stay with 4.10s or jump to 4.88s.

    I'm a bit torn between going with 4.88 and 5.29 with 35's and an auto trans myself, but people have said I can get away with a higher gear a bit easier with the auto. With being a manual trans, I think you could get away with 4.88's pretty good with 35's, being close to factory power. If you did drop down to 33's with a 4.88, you'd be a bit on the power side, but I dont think it'd be too awful as long as you dont punch it. I'd be really tempted to just leave it alone running 33's.

    No matter what tire you're going with, I'd suggest you try it out with that size before forking over the big $$$ for a regear. But that being said, make sure you have the money for the regear before you do the tires or keep the old tires to put back on if its undrivable with the new size.

    If you don't know what backlash is then you absolutely do not want to be doing your own gears. Even if you do know, you still probably don't want to do your own gears. They can be quite finicky, and expensive if you get them wrong. Cheapest way to do it with a shop, if you are feeling handy, is to pull the 3rd members yourself and bring them in.
