I feel like dolt, but I'm not understanding why the pinion has to point right at the t-case output? Isn't the purpose of the u-joint to deal with an angle difference? I know I'm missing something simple.

Thanks!

What your missing is the axle moves. If the axle pinion isn't pointing at the output of the t-case perfectly at ride height, how bad is the angle going to be during suspension travel on the road? or worse yet, at full flex on the trail? You'll still get vibrations with an improperly aligned pinion - even if you have a DC shaft. Vibrations lead to drivetrain damage.

AMAZING write up Unlimited04!!

Is that your handy dandy CAD work or was that taken from somewhere?

Very nice thanks!

It would be cool if you had included ball park pricing on the various components. It would also have been neat if you had further explained adjusting control arms in this write up. "Hidden Cost of a XX" suspension lift".

great post! the various driveshafts was one thing i was always confused about. all of my vehicles until the jeep had cv shafts so when people on different forums were saying to buy a sye and cv shaft i thought maybe i had just missed something and it meant something else in jeep land. then when i saw the dc shaft thrown in there i got really confused. i'm not going to be lifting for a while so i figured i'd just figure it out when it came time.

i really enjoy your writeups. i think most questions on here could be answered if people just took a few minutes to read your posts and understand what they are trying to do rather than just ask and have people tell them what to do. that way you'll know what you're doing (or having done) and why you're doing it. obviously people are still going to have questions, but at least then they'd be meaningful and would actually make sense.
