Driveshaft Installation
I just installed a front Tom Woods 1310 driveshaft on my 09 JK Unlimited Rubicon, 3.5" lift. The front universal joint is not in line with the shaft. What is the best way to align the shaft and u joint. I have adjustable lower control arms only.

you can't put your pinion in line with your shaft up front as that would result in negative caster. the best you can do is get it close to about stock caster which is +4.2°. too much more than that and you will have vibrations. any less than that and you will have a jeep that wanders all over the place. if this were a rear shaft, using adjustable upper arms is the best way to set your pinion angle.
