    Ok,, here goes,, 78 blazer with splined drive shaft about a foot or so from the front of the shaft. Tuff Country EZ ride 3" front 4 " rear springs. In order to get my drive shaft in, I have to beat the hell out of it with a rubber mallot until it completely bottoms out on the splines, then use a crow bar to get it into the yolk. Maybe this shaft was lengthened at one time,,, I don't know,, but,, My question is,, how much spline travel should there be? It will slide if the wheels drop and the angle of the shaft increases,, but I have to be really bottoming out when the rear wheels come up. Do I want the end of the front half right in the middle of the splines? Or do you not need as much up travel room as down?

    Thanks

    I called a drive shaft place and they said they will just measure from yolk to yolk and then they will know what length the shaft should be.
