I just replaced the 1350 ujoints in my standard 2 joint rear shaft. Reason being I adjusted my pinion angle by 5 degrees and wanted to start out with a fresh set of ujoints. Anyways, I took apart the spline section to clean it and the problem is that I forgot to mark it before doing so. Now my question is when I put it back together, for balancing issues, do I need to make sure that both ends are on the same axis as far as the joint is concerned, or do they need to be 90* off from eachother to help cancel themeslves out? Does this make sense?
