    I think the grease I used was garbage... It's still clunking, lol.

    Oh well... I'll use some of the Amsoil grease I just bought :thumbs:

    I used Marine wheel bearing grease on mine. Working fine so far.

    Stilll There

    When at a stop, I accellerate and you feel and here a clunk in the drivetrain.

    I used the best grease they had at autozone. It was waterproof as well.

    Just so I am sure, pack the yoke to the brim and let it push out what it doesn't need, correct?

    How much movement should I notice in the trans mount as I do notice some left and right movement when pushing back and forth on the driveshaft. Also, with the truck not running, I can the driveshaft about an 1/8th of a turn back and fourth, don't know if that is normal.

    Anyone care to elaborate more on the symptoms of needing this done?

    I never ride in any of the new trucks (don't know anyone with one either) so I have no idea what to be looking for.

    Anyone heard of the GMT400 trucks needing it yet? Mine is still fine with 123k on the clock. Seems odd that all of a sudden it started happening with the GMT800. You'd think they'd figure it out before the GMT900 came out.

    Just line the inside splines... don't fill the yoke. You don't want a bunch of excess grease ending up inside the transmission.

    Lay under your truck, grab the tail of the transmission and try to move it up and down. You will have to get in a position where you can watch the mount while you do this, There sould be little or no play at all.

    Some slop in the drive shaft is normal.
