    Hello All,

    I've got a 79 w/ stock 10bolt front and 12bolt rear. What are the options for beefing these up w/o a complete replacement to a 60+14FF.

    What can be done w/ the 10. Is there anything that will make it hold up to 35" tires?

    What about the 12bolt. Can it be made FF? Is there anything else I can do to harden it?

    Thanks,

    Check out http://www.offroaddesign.com for beefing up the 10 bolt. They have chromemoly axleshafts. Warn makes a full floater kit for the 12 bolt. You could also add trusses to both axles. If you don't want to break your axles, just go easy on the gas.

    Here are some suggestions:

    10 bolt:
    Locker
    Aftermarket gears
    ORD axle kits(a lot stronger than stock)
    Warn Premium hubs
    Axle truss( over axle so no to reduce ground clearance)


    12 bolt:
    Locker
    Aftermarket gears
    Warn Full floater kit or stronger after market axles
    Disc brakes
    Diff cover with bearing cap pre-load
    Axle truss(over axle so not to reduce ground clearance)
    I belive someone said something about a double row bearing someone was offering?

    I am sure someone could suggest more if I forgot something.

    I asked this same question about my D44 and 12 bolt to a guy that 4 wheels the piss out 10 bolts not 2 days ago. His answer, was my 10 bolt is just as strong as your D44. He told me, to get ORDs front axles & purchase quality axles for the rear (ie superior or moser or ?) Warn's full floater is available for $750 for the 12 bolt conversion. I figured I could get 5-6 14 bolts for this price. I decided that I will (no money for axles yet) carry a container to catch grease and an extra OEM axle thank you very much Mr. Warn. Oh, this same guy said he had never broken an after market axle, only the U joints. But OEM axles are very inconsistent in diameter and temper. I broke my 12 bolt rear axle just inside the bearing and when it was pulled out, the fracture had rusted!

    I've been checking out both the Warn kits for my 78. Everything I've read so far indicates that with the proper set up, my 10 bolt and 12 bolt could handle 35"s and be reliable on the trail. I don't like the prices, but I like fixing stuff in the dirt even less!
