OK, who knows how to put the RF axle u-joints in phase on a D50 front end? I researched this when I replaced the ball joints and u-joints a couple of years ago(ya, I didn't mark it), but the outside u-joint just came apart on me so I may have screwed the phasing up. I put it together so that the outside part of both u-joints were aligned. But also the failure may have been caused by the caps not being seated completely. I read a comment from a mechanic that recommended hitting the end of the joint with a hammer until it seats fully, but I don't know if that's BS or what... but it sounds good.
