Grand Cherokee Front Drive Shaft Rezeppa-Fixed Yoke
With the Rezeppa to Fixed yoke dive shaft, we have a couple of options available.
We can build a conventional double cardan (CV) drive shaft (our type A). This type of drive shaft seems to work well in applications with up to about 3-1/2" of lift. Even greater, if the possibility of a minor vibration is acceptable to you. This requires changing out-put flange on the transfer case to a yoke. This may require counting the splines on the front out-put of the transfer case. Plan on spending between $60 and $90 for this yoke.
Keep in mind though, that with greater lifts or the smoothest drive shaft, our multiple double cardan drive shaft may be your best choice (four U joints). This drive shaft can only be built with our S spline. The cost for this shaft is $619.You will also need a double cardan (cv) compatible yoke for the axle.
We will need a measurement for the length. Measure from either the flat machined mounting surface (face) which is just inside the pilot on the pinion flange or the lip of the flange to the face of the yoke on differential end.
The S spline is a conventional spline stub that will yield a safe, effective and usable stroke of 3”. The X spline is longer than the S spline. The X spline is cut for the full length of the spline stub. This gives a bit more than twice the contact area between the slip yoke and spline stub and a stroke of 4-1/2". This in and of itself will net more than twice the life on these two components.
With the XB configuration, we will use a heavy rubber boot which is banded down with stainless steel banding to seal all of the contaminates out and keep the grease in. The XC configuration uses the same slip yoke & spline stub but instead of using the rubber boot, we drill and tap the slip yoke for a grease fitting and use a dust cap which has convolutions that follow the spline stub for sealing. We consider the XB configuration to be the longest lasting and best value.
