    I have a 89 chevy blazer k5 with 3.73 gears stock transsy and transfer case and a add a leaf in the back and when im going between 55 and 65 after it has warmed up it sounds like bearing noice and then the noice goes away if u put the tranny in neautral. I have had the driveshaft balanched and done a 180 flip on it, ive put new u joints and new axel bearings plus new spiders. Could the noice be coming from the transfer case.

    Thanks for help or suggestions,

    Tony

    Is the sound coming from the very rear or in the middle?

    we had the bearings replaced as we said and we cant really tell where its coming from but we know its not in the front and someone told us it might be the chains are lose in the transfer case. /forums/images/graemlins/k5.gif
