    well this morning it sounds like my rear is making this
    clanking tanging noise when driving at slow speeds, like
    a clattering clanking . it started getting worse , then
    all of a sudden it felt like i was dragging a dead whale behind my truck , serious lagging. i was trying to get her home and she just seem to start bogging down when i would be climbing hills. i could punch it and get more speed but not anywhere where it should be. well i got home and pulled the diff cover and all seems to look ok unless i am missing something. all the spiders look good and so does the ring and pinion. my u joint looks tired but its not loose , so i dont think that is the problem . i cant really see if its the clutch pack. ( its a govlok by the way ). anybody have
    any ideas? . i dont want to pull the rear out if its not the problem. /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/1zhelp.gif

    Sounds more like your tranny. If it was your rear, you would have just blown it up.

    Also, physical problems would likely cause excessive heat at the diff. A "generic" test is to see if it's too hot to hold your hand on after driving normally.

    I agree with the other poster though, I doubt it would continue to work very long if something in the axle assembly is messed up. The tires spin ok when they are off the ground? Sure it's not a rear drum screwed up, or the e-brake?

    well i understand what your say with the fact that if it was the rear, it would have exploded . i have never heard
    of a auto tranny actually causing your vehicle feel as if
    it was bogging down . she shifts fine , no slipping. if i am wrong please explain. the clanging noise sounds as if it is somewhere in the rear of the vehicle, so i am going to pull the wheels and hubs to see if maybe something in their
    is wrong. i am really stumped /forums/images/graemlins/1zhelp.gif.

    My 10-bolt did the same things a couple years ago. It was a combination of warped rear drums, badly-adjusted rear brake shoes, and dead rear U-joints. So dead that one of the caps on the axle-end U-joint had only rust dust, small chunks, and FOUR intact needle bearings. /forums/images/graemlins/eek.gif I had tried to grease them a few times, but the grease ports in the cross were clogged by rust (and needle bearing chunks) at the cap ends.

    Check your axle bearings also but it sounds more like u joints or brakes.
