    did they make a 10 bolt corprate rear axle. If they were made
    are they worth puttin in or will it be junk. I know a guy who says he has one he wants $50.00 I am just wondering
    if it may be a 14 bolt and he does not know it.

    HEY Fords!!! how many flushes does it
    take to get rid of you

    You can tell what kind of axle it is by counting the number of bolts in the diff. cover....

    Corp 10-bolt was stock on most K5's, wasn't it?? cK5 has an axle-id chart that I find pretty helpful. Check it out <A target="_blank" HREF=http://coloradok5.com/axleguide.shtml>http://coloradok5.com/axleguide.shtml</A>.

    14ff = Full floater. Axle serves as a drive axle only. Carries no load.

    On 10, 12, & 14SF (semi floater) the axle transfers all the torque to the wheel and supports the weight of the truck. A full floater has wheel bearings and a spindle like the front that support the load and the axle shaft only transmits the torque. Because the axle shaft on a FF only has one "job" it is much stronger.

    Bah, my rear is a 10-bolt...and a full floater... =p I agree that the 10-bolt isnt the worlds greatest...but with the ff and 30-spline chrome-moly axels in there, its not too bad. I run 35s and with my lil 350 its not a problem. Just dont drive like an idiot and its all good. ;)

    10 bolts are not full floaters unless you got the Warn kit to convert it.

    Speaking of the full floater kit... I've got a 10 bolt rear. I don't do any hardcore off roading, no rocks, nothing like that. But I also don't want my 10 bolt grenading every time I get an itch to do some minor off roading. I don't want a 14FF for a few reasons, 1 cost in changing gearing, changing to 8lug wheels, and the size of the dang thing. And upgrading to a 12bolt, while I'm sure an improvement, would also probably require regearing and it wouldn't be THAT big of an improvement.

    SO any way, my question is, if I drop a Warn FF kit in my 10bolt, would it handle mild off roading with max of 35" tires? I've got a 305 now but I eventually would like a 350.

    Personally, I have never experienced the Warn kit. Stephen Watson did on his green ORD blazer.
    From what I have heard and read, the Warn kit is better than the stock set up. You definitely should be ok with this set up and tire size as long as you do one thing: drive moderately. No hardcore, bat-out-of-hell, BANZAI, etc. driving.
    If you could locate a 12 bolt and install the Warn kit on that, then you are in a better league. Would you be changing the gear ratio? If so, then a 12 bolt would be a better candidate for the gear swap and Warn kit.
    I have experienced the 12 bolt myself and blown up a few. That was with hard and some mild off roading. I am not trying to scare you, but everybody is different. I have damaged three 12 bolts on 3 different trucks and that was enough for me to try out a 3/4 ton and also a 1 ton. I have never gone back after that. Just my .02 worth.

    BigBrown - I'm in the same situation you are in. this is what I'm gonna do (sometime) I'm going to pick up a 14SF at a junkyard for an 81-87 3/4 ton PU, put new beaings, races, possibly a locker in it, and then do the swap. Plus, I'll get 4.10 gears. this whole thing should cost about the same or slightly more than the FF kit for a 10bolt. I'm going to take my time working on the 14SF while my 10 bolt is still good, and then swap them when I'm ready.

    There are millions of 10 bolts out there. Hard core wheeling, doing burnouts, and driving crazy if it is a gov-lock rear axle, will surely result in destruction. Looked at another way, my 1983 K5 with 140K+ on it had the original axle assembly in it, and my K5 now has unknown mileage 10 bolts in it as well, and I have no concerns about breaking it when I go "off roading" hunting. Big tires and lots of power are going to break axles, while big tires with the gov lock are going to break the carrier. Spinning tires with an open rear axle (not posi) will result in rear axle destruction as well.

    Since it is usually the gears or carrier that break in a 10 bolt, it seems like the FF kit is good money after bad in that axle. It will help you get off the trail when it does break though.
