Adding new Tom Woods drive shaft

[OldBuzzard]

... do it right and install a slip-yoke eliminator in your transfer-case and fix the excessive pinion-angle once and for all.

He's in a Rubi, doesn't have a slip yoke to eliminate.

So what should my angles be on the new install? Lots of YouTube videos out there but lots of varying info. Thanks in advance.

Your pinion should be 1-2 degrees less than the angle of the drive shaft. For example, if your drive shaft is 15 your pinion should be 13-14. You can see this demonstrated in this video . Skip to around 7:00 minutes if you want to jump right to the good stuff. Watch the whole thing if you want to understand things more completely. Or maybe you've already seen this and it's one of the videos you are referring to. If you are finding varying information it is mostly because a lot of people are focused on non-lifted vehicles and cars. For those vehicles the rules are different because the total angle is less severe.

I just saw the topic- Current forum regulations limit you to 2 drive shafts per vehicle.

Please don’t add one. We don’t even have a form to apply to do that. Yet.

If it weren’t for me this TJ thing would get completely out of hand.

Adjusting his pinion angle up with his stock driveshaft will put the u-joints further out of phase won't it? The TC output shaft and pinion shaft need to be parallel. He needs the adjustable arms and a DC driveshaft.

Raising the pinion angle will increase the angles the driveshaft u-joints are operating into but that doesn't affect or change the phase. The pinion angle should never be changed with adjustable length control arms for the OEM rear driveshaft.

I had adj.arms before I got a DC driveshaft.
And yes, I lowered the pinion (which tilts up after a lift) to better match my TC output.
The problem is there's a greater potential for maxing out the u-joints.
Especially when the axle droops lower than ride height.
