Jeep Wrangler TJ Rubicon Front Drive Shaft
The stock Rubicon front drive shaft is a 1330 series CV (double cardan) drive shaft. Unless there has been a failure or damage to a stock drive shaft, there is not usually a need to replace the front drive shaft when lifting this vehicle.
For the front CV drive shaft we have two options available. Either drive shaft will be built using upgraded heavy wall tube, larger/stronger slip yoke & spline stub and our “Gold Seal” universal joints. With our S spline, the drive shaft is $349.00. Our top of the line shaft with the longer travel X spline with XC or XB slip yoke is $369.00.
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. The XB is best for wet and dirty conditions. The XC is best for rocks and extreme wheeling.
We will need to know the length of the drive shaft. Per the photo, take this measurement from the face of the out-put yoke on the transfer case to the face of the yoke on the differential, will be the same as center-line of universal joints on the drive shaft, in the installed running position.
