    Ok I found two different sets for axles both dana 44 fronts with 8 lugs and 14b rears one says 4.10's and the other says 4.11's. Both would suit me. The ads say nothing about condition. Both listed as $500/set. My questions are, What should I look out for on these? Is this a fair price?(seems reasonable from what I have seen)., What should I ask about these?, If these need seals and bearings, how much would it be? Thanks.

    Fill out your profile a little more.....what year vehicle are these for?

    You may not know this, but the spring pad width is different between the early K5's and the later models. Depending on the "donor vehicle" the spring perches may line up perfectly, or you may have to cut them off and relocate them.....AFAIK this is only a rear axle issue, I don't remember hearing about people having spring pad width issues on D44 fronts.

    Avoid "Closed Knuckle" D44's (They are OLD) and if you are considering going to a crossover steering setup, it will be nice to find a D44 with a flat top passenger-side knuckle.....you'll need that flat surface to mount the crossover steering arm.

    That's a few things to consider, but please fill out the profile and tell us a little more about what you're trying to do......the answers will start coming! /forums/images/icons/smile.gif

    No 73 up are all open but some of the 73's ran a smaller ujoint than the newer ones. You can swap the shafts to get the bigger joint but unless they were free I would skip them.
    I would also skip the external locking hub models. Those are usualy through about 74 and odds are the small joints. Get the ones that have the hub like the ones on your half ton axle. They are the same locking hub as your 10 bolt runs. Also if you didn't know you can take the sprindle, hubs and backing plate off a 8 lug and it will bolt on to your existing half ton axle if you already have the gears you want to run in that axle it might be a good option and then you just need to get the rear axle you want. There is a write up on the conversion by Waxer in the tech section on the main CK5 page.

    Re: Found some axels for sale...Need advice

    Ok these are for my '83 GMC sierra classic. I have a broken carrier in the rear 10 bolt. I'm currently running 33's with 3.42's and a 700r4. My thinking is that this dana 44 eight lug and 14b ff with 4.11's will do nicely with some 35" tires on my rig. The guy said that the axels were off of a 79 truck. Does it sound like these are the right stuff for my rig?

    Re: Found some axels for sale...Need advice

    Sounds like a good place to start, but be sure to take your time when checking out the axles you want to buy. Pull the diff covers and look for metal shavings in the gear oil and case, broken or worn ring gear or pinion teeth, condition of the axleshafts, brakes, etc. Good luck.

    4.10's, 33's and a 700r4 are a real good combo. 35's are going to have it hunting a little in and out of OD but not near as bad as the 3.42 and 33's. Should be a pretty good set up. 79 will be a good year for the doaner parts but my bet is the front axle is a 10 bolt not a D44.

    what's the easiest way to I.D. the dana 44? I know what the 10b's look like, but I wanna be sure because I'm far from knowledgable in this area.

    4.11s and 35s will suck with a 700R4. If you want 35s, get your gears changed to 4.56s.

    Re: Found some axels for sale...Need advice

    What's the stock tire size for an '83 Blazer? I was guessing 31". And looking at this chart http://rough.roughcountry.com/Gear%20Ratio%20Guide.htmlooks like 4.11's and 35's would atleast get me closer to what my rig was stock, but I suppose if i wanted stock, I wouldn't be buyin' new axles anyway.

    the 10 bolt cover, you know what that looks like...
    the dana 44 is pretty much the same dif other then the centre section, so dif cover has the traditional dana shape and bolt spacing.
    there will be some metal paste in a used dif.
    definitely do the 14ff swap, one of the, if not the, best light truck rear difs
    issues you have to address is
    8 lug 16"+ rims or grinding to fit 15"s
    driveshaft/ujoints

    Re: Found some axels for sale...Need advice

    cause what i have now is a 1/2ton D44(full-time) and a 12bsf with 3/07's and i wanna swap to 3/4ton D44(full-time) and a 14bff with 4.10's...the 14b will be somewhat easy to find, was just wondering about the 3/4ton D44 in which vehicles to look.

    The Colorado K5 axle guide /forums/images/icons/smile.gif You really should snoop around that front page some. There is a bunch of good stuff in that tech section.

    [/ QUOTE ] He has a deisel so it won't be quite that bad for him just because of the low end torque. Still going to put a little load on the 700. Needs to get a BIG cooler on that booger for sure.
