    Often times a yoke will get a little hammered on some rocks and make a stress riser that will eventually give out. Don't know about the pinion other than it must have had a lot of years on it. I'd keep the axles you have unless you just want to spend some money on the upgrades. The Scout axles are about 5" wider than the stock axles, I'm sure the Waggy axles are around that size too. If you are running 5.38 gears you have to watch the right foot with 35's. Even a V6 can generate a lot of torque to the axles with those gears. Axles usually give out before the other stuff you mentioned. I'd fix it and run it.

    Hope you still had FUN AT MOAB!!!
    You might look into a 30 spline (warn full floater) type of upgrade for your D44.
    I think they quit making the warn kit, but people still do it some how.
    I don't have any answers for the u-joints, have not had to deal with that yet!
    What trail was you on? or what trails did you run before your breakdown?

    I lost a rollpin in my lockrite, when I undone the rear hub all the power to the front (old D25) lasted about 30 seconds!!! stripped all the gears off the spiders.
    I could go pretty good untill I lost the locked rear, then I was toast.
    Moab is great even being towed was kind of fun!! LOL!!
    Anyway I'm working on axles also because of Moab!
    I have a D30 just had not put it in yet (never had time) guess now I'll just have to make time!!

    BIG BIG THANKS to Derek and Raelynn for the awsome tow to the trailhead.

    Go with a Wag. 44 over the scout. The scout outers are the same size a D30 and they have no caster which means you will more than likely have to cut and turn the knuckles.

    One of the diffrence between waggy and scout axles.. is the castor angle on them. I think the scout has 0 degrees and waggy is something like 6 degrees.

    Since you did a SOA and running 35" tires.. I think the wider axles would be a great upgrade for you jeep.

    I am wondering.. do you have a traction bar to prevent axle wrap on your rear axle ? If not.. I am guessing that is why you broke your u joints.

    Good point! Not that uncommon to break u-joints on a rear D44, but usually other things go first. You wonder if the u-joint broke first and took out the yoke or did the yoke break and trash the u-joint.

    I can guess it isnt that motor thats in the jeep that is trashing U-joints ;) :) :) R)R)

    I did waggies on my CJ5. Worked great. I prefered them over the scouts becuase of the caster. They are a little wider than the scouts but it fits real nice.

    The Scout 2 front, as said, suffers from serious Caster issues. The arms on the knuckles are way too long as well, although 30 front knuckles can be easily swapped in with the spindles, hubs, and locking hubs. The waggy axle is much better in this respect. A Scout 2 rear axle would work good as they are centered much better if running a 20 or 300 transfer case. If running the offset 18 then a Waggy that had Quadratrac would be a good choice and can be picked up cheap. Just sold one for $50 about a month ago. Down side to Waggy is most are 6 lug, but not a real issue for most.... With either the waggy or scout2 front the springs will need to be mounted outboard of the frame. Nickmil.

    '74 or '75 up to '79. I believe it was in '80 the front went to a Driver's side pumpkin which is the wrong side for your transfer case front output. The rear can be later than '79 but you may get an AMC 20, which from a Wagoneer isn't too bad but gears can be more expensive than a 44 and are more limited in ratios and lockers if you decide you need them down the road. Plus they use a crush sleeve to set pinion pre load vs. solid shims like the 44.

    Spring mounts on the 'outside' of the frame vs directly under the frame.
