the reason nobody ever talks about the number 2 pic
being correct is because (they don't want you to do it )if you try it on a leaf sprung vehicle axle wrap will kill your u-joint ,pinion seal and bearing or under severe acceleration shear off your pinion . i no because i had it set up this way on my small block powered landcruiser and spring -over with 38's every time i hit the gas my u-joint would bind so bad it finally sheard off my pinion .BUT I NEVER HAD DRIVELINE VIBE. it worked great in the city and on the highway .
you can do this mod on the sidekick because everything is held in place solid by the control arms you also don't need to lengthen control arms ,by rotating the axle the mount on the axle moves closer to the arm then the arm pushes the axle back. .giving more tire clearance .
anybody ever seen a tractor pulling a trailer (bailer) hooked up to the pto spinning around all over the feild they seldom wear out u-joint . they run some wild angles on their farm equipment .without any pto drive shaft vibe .
