I know the LR has been lifted a couple of inches with spacers and the rear driveshaft has been replaced with aftermarket. I believe the front has been too but I don't know (three ujoints). I will provide pictures in the attachment section.

First is the driveshaft. There is a vibration at 55+ MPH and I want to test to see if the front DS is the problem. The way I understand it is the 2002 doesn't have the CDL option so my question is can I still pull the driveshaft and drive without the ability to engage the CDL? I believe the front driveshaft has been replaced and I know the rear has, the rear doesn't have the rotoflex. The front DS looks like its got three brand new Ujoints from diff to Tcase. My son is driving me crazy to fix his first ride. How can I test the front shaft on the 2002?

Second is the AC only works on high and again research tells me it the resistor that has gone bad, I've not actually been able to find where its actually located or what it looks like on the passenger side but I have a good idea but I understand it also has a Final stage resistor and I don't know the difference. I've seen that some people have soldered the resistor off and the new one back on for the fix. I would like to do this option but need some more detail to do it since its a lot cheaper to fix it then replace it.
