How much of the slip yoke in the rear driveshaft should be exposed at ride height on an Xterra? I did a rear axle swap and SOA and forgot to take not of this. ow the driveshaft has to be lengthened and I want to make sure I do it right. the slip shaft has a maximum of 6"-6.5" travel before it fall out so I'm thinking 4.5" in and 1.5"-2" exposed. Sound good?
