    I was at a friends house in the woods, and they had a new black top rd.
    We went riding around, and I thought I would down shift, and floor it :D .
    Boy was it fun (454/350trans). Bad thing is I plit the trans in half :doah: .

    U-HAUL did not have a trailer or dollie to pull my truck home, about
    40 miles away from my house. My friend suggest we pull it with his truck.
    No big deal. I put the transfer case in neutral and the trans in neutral.
    We stop to get gas, for his truck, and at some point, I'm sure when we stoped for gas I put the trans in park. We took of, And I forgot to put the trans in neutral again. So at this point the T/C is the only one in neutral :doah:
    We get about 30 miles from my house and I smell gear iol burning and notice
    my truck feel real heavy on the pull. I get the driver to pull over and I get out the truck, look underneath and both my DIFF's front and rear are SMOKING
    BAD.

    I put the trans in neutral and the T-C is still in neutral, I hope it worked.
    2 miles in the pull the truck felt heavier:eek1: , we pull over again and the DIFF's are smoking real bad, PURE WHITE TO, like if they got red hot. Well the truck did not want to budge. I ended up calling a flat bed (SAFE CLEAR SUCKS)
    and they came out with a normal tow truck. He lifted it upfrom the front and moved it back and forth a foot or so, and it seem to be binding in the rear,
    the rear wheels would move then lock up. I'm pissed at this point, I tell the wrecker driver to give me a 7/16 to pull the rear drive shaft. I pull it off and truck moves freely now :confused: . We get it home, he drops it off in my drive way and it would roll with out the rear shaft:confused: .

    I dont understand how my diff's would get so FREAKIN HOT.
    The gear oil on the front shaft shot out one side. What did I do?????
    Did I ruin my T/C???

    i dont understand why the front differential would have any problems at all. to me the problem lies in the t-case being in neutral. i say this because when i took my drive shaft off, putting it in park did nothing because the rear diff wouldnt lock up.


    thats basically all i know, someone else should know

    I don't get it, the diffs front and rear are smoking, but when you take the driveshafts off the diffs it rolls freely?
    Where the diffs hot to the touch? What about the trans?

    Yea, both diff's were smokin super hot, the gear lube up front
    shot out the driver side axel seal. both covers turned ghost white.

    The trans is split in half, but still in. I will post pic's later.
    I just don't get it. The T/C was in neutral the whole time.

    I personally think you had more problems than just your tranny splitting. Maybe your axles caused the tranny failure. Once the transfer case is in neutral it should roll very easily even if the tranny is in park. Also my transfer case in neutral cause boths driveshaft to turn. Don't know if this caused some issues you might have had with a locker in the front.

    The front shouldn't turn unless you didn't unlock your hubs. Or do you have full time 4x4? Correct me if I'm wrong, but I don't think was available in 82.

    Wait, if you put the tranny in park then that shouldn't do anything if the t-case was in nuetral. Are you sure the t-case was fully in neutral?

    Yup, it was in neutral.

    I do not have to lock or unlock my hubs. I can just put it in 4X4
    mode from inside the the truck, and unlock it from inside also. I have
    to back up like 10 feet in reverse to unlock it.

    Ah, auto hubs, thats what I have they are kinda crapy but slightly convinient. Your front drive shaft shouldn't be stinning if your hubs are unlocked.

    if you have auto hubs the rear shaft would turn the front ^and lock the hubs

    so your axels are locked together which can be very bad on dry pavement at highway speed
    just like driving on dry pavment in 4x4

    Couldn't you have just left the tcase in 2wd? Putting it in neutral would lock your front auto lock hubs, so leaving it in 2wd would keep just the rear driveshaft spinning, right?

    That's what my '85 K5 (700R4/NP208/autohubs) owner's manual indicates:
    --------------------------
    [Towing this vehicle] with all four wheels on ground

    1. TC in 2H
    2. Trans in neutral
    3. Max speed 35mph
    4. Max distance 50 miles

    Note: For speeds over 35mph or distances over 50 miles, remove front propshaft and store in vehicle. Disconnect the rear propshaft [because it's a slip-yoke into the TC] at the rear axle carrier and secure in a safe position [so that the slip-yoke won't slip-out]. Tape u-joint bearing journal caps securely in place.
    -------------------------------------

    That's Chevy's boldfaced note, not mine, but I did add the non-boldface comments. There are also similar instructions for front wheels off ground, as well as rear wheels off ground. Socket set. Some wrenches. Fibertape. Mechanic's wire.

    what, the rear drive shaft ??

    I did not pull the shaft, because the tranny was already toast.
