    Beefing up my 10 bolt to withstand 39.5\'s

    Now that I have my 39.5's I need more strength before I do some decent wheeln'. I've got a 14FF that I'm installing and I'm converting my 10 Bolt to 3/4 ton 8 lug. I need some opinions on what I need to make my front 10 bolt handle these 39.5's. I can't afford a D60 nor can I find one right now, so I need to make my setup work for now. /forums/images/icons/crazy.gif HOPEFULLY

    When I went to 39.5s, I broke a lot in my D44--spider gears, both inner shafts, one stub shaft, and both u-joints, all at once. But it took a while before it broke. Anyhow, this was with stock parts, so I think with some Chrome-moly axleshafts from Warn, some CTM u-joints, and a detroit locker, you would have a tough axle that would survive pretty well depanding on how heavy your right foot is. But all these modifications will run about $1000, so why not just go with a D60? My .02. /forums/images/icons/smile.gif

    <font color="green"> I tried to beef my D44 for 38s, spent well over $1k on it and still broke it all the time. Once I got all of the parts in my axle upgraded I started braking ring gears. And I didn't even have CTM joints. You're going to have bigger tires, and a marginally weaker axle. Save the money, limp it along, fix the breakage with cheap stock parts and save the money for a 60. </font color>

    you will spend more than what a D60 would cost and it still isn't enough for 39.5s, IMO. I am a strong supporter of the 1/2 ton stuff. I think one of the reasons it gets such a bad rap is from people trying to run big (38+) tires on it. The 1/2 stuff is great up to a 35 or 36, but even then it can still break.

    I'm with shaggy on this one. 10 bolt parts are dime a dozen around me, a 10 bolt front axle is only $20, manual hubs $21. I carry all I can and oddly don't break when I have them, only when I forget em...Murphy's law I guess. Keep saving and searching, that D60 will show upsomeday.

    D60. you are half way between LA and Arizona, two places with good wheeling populations. scoure (sp?) the classifieds and keep looking for your D60. it might take a while to find one at the right price, but they do come around...

    adam it looks like a D60 would be about the same price. and wouldn't you just love to see a D60 under the front of the jimmy? i'll most likely come back from colledge with one, it's inevitable man. if i were you i'd just get your front shaft made up and take it easy til you can afford a 60. if you break, you break, we learn how to replace axleshafts and u joints.
