so i was replacing my my front U-joints and the drive shaft slid apart . i must not of put it back right because there is a knock in 4wd. how do i get my drive shaft phased right again.
thanx for the help.

 

No big deal. Some driveshaft splines will have a mark on the end or sometimes one spline will have some form of indication....like a notch cut out on the end or one will be bigger... to match up to the yoke. If yours doesn't have either, pull the yoke back off and line the flanges up. Turn the yoke so that the bolt holes match in direct opposition to the rear flange. Hope that makes sense.
