X2 on what BigSahara said above. Don't even try to drive your Jeep after installing the new Tom Wood (not Woods) CV driveshaft until you have properly set the rear pinion angle. If you don't adjust the rear pinion angle properly after installing the CV driveshaft, you will have major drivetrain vibrations. You can get away with just buying upper-rear adjustable length control arms to raise your rear pinion angle to where it needs to be. Lengthen the upper arms to the point the pinion angle is where it needs to be. Make sure both upper rear arms are set to the exact same length. I set the length of one control arm first to set the pinion angle and then I adjust the length of the other until it matches and its mounting bolt holes line up with the mounting bracket.
The pinion angle needs to be the same as the rear driveshaft angle. Equal to or perhaps 1-2 degrees under that of the driveshaft. However, the pinion angle cannot be even 1 degree above that above the driveshaft.
Here is how your rear axle's pinion angle should look after you adjust it up to match the slope of the driveshaft.
