    my 1990 f350 mason dump, manuel trans 2wd broke the front u joint while plowing so i droped the rest of the driveshaft. fixed the joint changed the output seal on the trans. then hooked it all upt. heres my problem. got in the cab to try things out. started to go foward and it was like the parking brake was on. couldnt go forward. then put it in reverse and was able to backup about 5 to 6 feet then it was like hitting a hall. i think something is messed up with the diff.
    truck is stuck in one of my lots
    if anyone can help please let me know your thoughts. also if i can do the work or is this something to leave to the pro. and cost ideas
    thanks

    Something in the rear axle likely let go first and is what caused it to break the front U-joint. The fact that it will move only a few feet tells me it probably lost some teeth from the ring gear most likely. Needs to come apart. :(

    You can at least remove the diff cover and check for carnage. Possibly even remove the broken chunks enough to nurse it home depending on the damage and distance needed to be traveled.

    But diff work beyond that should be left to a pro.

    Well that would first depend on what all it needs. Best to wait and check into that first. Then go from there. However there's plenty of reasonably priced kits out there. Even a salvage yard complete unit may be a better approach, just depends on what it will require once it's checked out.

    Just ask away Brother were here to help if we can.

    If you need parts use the Internet to find them. You can find stuff cheap sometimes. A lot of 4x4 magazines have ads for axle shops that can fix you right up. If all else fails get your parts at a medium to heavy duty truck part places. They can get you parts at about 2/3's of what an OEM dealer would cost.
