    Quick CSB install question.

    I did the whole subframe/t-arm bushing replace and decided to install new CSB and flex disc. The question I have is how much of the splines should show on the d-shaft behind the CSB? I have about 2 inches of exposed splines between the end of the spline and the CSB. Is that okay?

    The CSB needs to go all the way on, there's a place on the driveshaft where the snap ring rides that holds the CSB.

      The snapring is on but it's just that 2 inches of the splines are showing behind the CSB. I unbolted the shaft from the diff and tried to push it in and the shaft in that case wouldn't reach the diff.

          the splindle teeth are usually are very dirty give them a thorough clean with pb blaster or wd 40. are you saying, you got the splindle all the way into the csb but now its too short to bold the diff?...

            I am saying that the spindle is connected where the CSB is, but if I disconnect the Driveshaft at the diff I can push the spindle in more into the driveshaft where the CSB is. I however in that case will not be able to reach the driveshaft to the diff.

            so right now it looks like _______[CSB]--______[Diff]

            the -- is the spindle behind the CSB

            If I push the spindle all the way in, it would be like this...

            _______[CSB]_______ (space) [Diff]

            There would be too much space and I would be able to reach the driveshaft to the diff.
