For the Jeep TJ Rubicon edition, a double cardan drive shaft can be installed in a number of ways.
One of these methods would require changing the original equipment rear out-put flange & mass vibration dampener to a yoke. This type of conversion will yield the longest possible drive shaft but we consider this to be almost a non issue as the net length gain will reduce the operating angle at the transfer case by only 2 degrees in most cases. It is not generally suggested that the yoke type conversion be done on vehicles with the manual transmission. As removing the mass vibration dampener hub will eliminate the torsional dampening effect of this hub and may induce some transmission gear clatter.
The other method that we have had greatest success with, is to make an adapter that mates on one side to the original equipment rear out-put flange & mass vibration dampener and on the other side to the double cardan (CV) drive shaft that we build. The benefits to this type of conversion as we see them are;
- Ease of installation. Does not require removal of the original equipment rear out-put flange & mass vibration dampener.
- Retains the effect of the original equipment rear out-put flange & mass vibration dampener.
- In the event of failure of the CV drive shaft, the original equipment drive shaft can be readily reinstalled with simple hand tools.
- We have had the greatest success with this type of drive shaft in regards to customer satisfaction of drive ability issues (reduced vibration complaints after install)
Either the yoke type or the flanged adapter type CV drive shaft for the Jeep Rubicon is $369.00.
Keep in mind that this drive shaft will flex to about 30 degrees prior to binding. We have had good success with this in applications using up to 4-1/2" of lift. If you have more lift than this and/or also installing a long arm kit or will be raising the transfer case, we suggest that some grind work be done to the CV prior to assembly. This will typically allow for about 35 degrees of flexibility to the CV prior to binding. This additional grind work adds $70.00
In order to build we would need a measurement from the vehicle. Simply measure from the face of the out-put flange/mass vibration dampener hub (point A) on the rear of the transfer case. (This will be the mating surface between this hub and the face of the flange on the drive shaft) To the centerline of the universal joint at the differential end.
Please keep in mind that the drive shaft shown in the photo has been polished and clear coated, this finish adds $15.00 the cost. We only recommend the polish & clear coat for show vehicles or very dry climates.
