    Rear yoke slippin\' ujoint is sloppy in the saddle?

    This is on my 90 K5 (stock rear shaft and yoke) I noticed that even after changing out u-joints, the rear joint slips in the yoke with the straps tightned down all the way. I removed some metal with a grinder on the yoke where the straps bolt down to try and tighten the straps up (and keep good contact all the way around) Now I can get the straps tight, but am having problems centering the joint in the yoke. Is there Any way to get the joint dead center so that I don't vibrate? /forums/images/graemlins/confused.gif

    Thanx

    Are you using the c-clips that go around the u-joint caps? That is all you should need to keep the u-joint in place.

    yes I'm using the clips, but there is play inbetween the straps and where the clip on the joint cap is. maybe the yoke is widened itself over time? I already replaced the traps with new ones.

    Had a rear yoke that was worn out from having the straps incorrectly tightened before. U-joints went bad in less than 2 weeks.

    Replaced it for $60, and never had another problem.

    It seems to me you are either using the wrong U-joint or the yoke is worn out.

    yeah the yoke has wear in it, you can see where the joint is sloppin around, How about those running boards? I'm still interested..

    Should I look at replacing the yoke? where to get one?

    ThanX

    If you are sure all the parts are correct, and installed right, then yes, if there is wear in the yoke, it HAS to be replaced.

    Driveline shop should be able to get them, or GM, if you'd like me to look up the number.

    $60 from the driveline shop last I checked.

    wrong size caps if they are loose int he yoke with strap bolts tight, ive had this happen to me in the past, theres a coupel sizes that are damn close same diameter almost, but just not close enough, i dont know why or what applications though, probablyfrom 70';s to 80's

    original drivelines under that truck, or?
