Driveshaft vibe test:

1) get Jeep into speed range where vibes happen

2) put transmission in neutral

3) take notice of vibes/ lack of vibes

4) if vibes are still present in neutral most likely the DS is out of balance, if vibes are gone then it maybe something else (bad pinion angle, bad u-joints, etc.)

Various torque values:

Wheel lug nuts: 85 ft lbs
