Ok, while I was installing my 4" front springs i tried doing it without removing my front driveshaft and while I was trying to position the axle and springs the axle slid way far forward and my slip yoke pulled out, I tried putting the two back together but they wont go together There is a ring that must hold in the grease and it wont fit over the splines on the Dshaft? Also I would assume the Dshaft was ballanced as one so I suppose if I do get it back together I will have to get it rebalanced, right? So how do I get this thing back together and will I have to have it balanced? Secondly, while I was taking the front part of the driveshaft off the pinion yoke one of the caps came off and needle bearings flew everywhere, now I already got the old ujoint out but when I went to put the new one in I screwed it all up and I am wondering how to do it right. I placed the capless ujoint in the yoke, but once I went to hammer the new caps in the needle bearings fell over right away and most of them fell out of one of the caps How do you do this without the bearings falling out????
