As a part of the u joint replacement I took the shaft apart (2pieces) and now I can't put the 2 pieces together. It just does not get back in. Can anyone tell me what am I doing wrong?

 

are you using a lot of grease? Also, did you index the two pieces so you could put them back together the same way they came apart?

 

I made the mark but with all the grease I am not sure anymore if I am doing it in the same spot. Need help

 

Ok problem was solved. For those like me (benigers). There is a guide (mark) in one of the arms that hold the U Joint and another inside the long part of the shaft. Just make sure you align both and the 2 pieces will be together like butter.
