Root Moose said:Normally mfg'ers use CVs where they are concerned about noise and vibration levels. CVs are less prone to these things. In the case of WJs I guess they figured no one would wheel them and then when they did got tired of warranty replacing joints. That's pure speculation on my part.
Jeep has not made a vehicle specifically as an off road tool for more than 30 years. Even the Wranglers are road cars with off road capabilities. That's why there is such a diverse after market parts supply for these vehicles. Some models can be more successfully converted to off road use than others.
