    I broke my front shaft on my 77 k5... made a hole in the tranny bottom . ( welded and fixed. )

    Now the question.

    front shaft has 3 joints.. on in bottom and 2 up with the t-case.... between te 2 joints there is a "centerball" ?

    Mine "centerball reciver " is bent.. .. I can make the shaft fit if I install new joints... can i do this ?

    Will the joints hold it togheter ?







    And yesterday I broke my rear shaft . God D**m.
    doing 75 miles on the higway... KABOOM. big noise. speedo going nuts at warp speed. lol....
    And a terrible noise under the truck...
    upper joint to the t-case broken...
    But only damaged was a big dent under the floor.. shaft ok.. just need to change the joint.. i was going to but the weather was so nice so i dropped the roof and went for a spin....

    On the way home the towtruck explodes his front tire. LOL. so we had to get another rescue truck to ...

    Damn! You may get some new vibes when you put that rear shaft back in. I have been told that the centering ball is required, but Jesse (drivelineman) could give you the real truth.

    Yes you can rebuild the front shaft. I've done a couple, The centering flang in mine was $50 from Napa (the needle bearings were gone)Just make sure the needle bearings stay seated properly in the centering flang. If you have a Harbor Frieght nearby I would really suggest buying the u-joint/ball joint/king pin press to save you time and frustration. If you change u-joints more then a couple times a year then it's in your best interest to pick one of these tools up for $40. Not to mention it makes a trail repair of a u-joint likity split.

    The rear shaft is back in with new u-joints. First time i ever did that.. still learning abouth my truck /forums/images/icons/smile.gif .
    AND no vibes.... i guess i was lucky as hell.

    Have to take another trip to the shop and get a u-joint for the front. I am still not sure how i can fix that one.. cant see how the centering ball/housing can be changed..

    I haven't replaced the center ball yet but I think if you take the ujoints out the ball comes apart and can be replaced.
