    Any idea how much spline contact you need on the drive shaft to a 241C transfer case? I lost about 1" in the slip yoke after installing a 14 Bolt Full Floater. I've got 2 3/4" spline contact when the truck sits loaded and 2 1/2" with the suspension fully extended. Should I have the drive shaft lengthened?

    Thanks,
    Eric M.

    I don't have more than that and it's been working for years, but I have 33" tires on it.
    How big are yours?
