I was wondering if there was some sort of formula that you use to figure out the length of your driveshaft, like x inches lift= x inches
of driveshaft length.
also, to make a cv driveshaft, is that an actuall cv joint, or just 2 u-joints in line? and do you do it at both ends or just the end that is
nearest the t-case?

/wwwthreads_images/icons/tongue.gif You would have to "Box" the problem...that is you create an imaginary box(a cube) of which the corners are the center of pivot for the u-joints and then figure in the angle of drop and the angle of offset, then solve the triangles for the length. Of course it's tougher do that for CV joints, and then there is the slip yolk to figure in, so it is really more complex than doing it with a tape if the truth be known/wwwthreads_images/icons/crazy.gif. A CV joint is actually a little driveshaft, all self-contained, self-cancelling. You cannot duplicate it with two u-joints without having a way to support the shaft between them./wwwthreads_images/icons/wink.gif You put the CV joint at the t-case, taking all the angle there....and then zero angle the rear(or front) by making the yolk point DIRECTLY at the t-case cv joint./wwwthreads_images/icons/wink.gif
