The slip joint should be at the front or trans side of the shaft. the u-joints should be in line with each other and the two yokes onthe drive shaft should be pointed the same way, one way to check is get one yoke so it is pointed at the ground, then see it the yoke on the other end is too, if not it's out of time, and if the drive shaft yoke at the rear axle is poitner down, and the yoke at the trans end is pointed to the side, that is wrong too, its off 90 degrees. Some drive lines you can't this wrong on, they have one wide spline inthe slip joint, but most don't and I have a bunch of them out of time, it will eat u-joints like crazy.
