Well finally broke down and purchased a rear shaft after toasting mine at Rausch creek. I went to a local company to have them make me one but they said a company is now stocking them and they are stout. Company is powertrain. Here is a review. Replacing a Jeep Wrangler JK Driveshaft: Off-Road.com. Anyway here are some pics. Just seems like I'm not seeing something as there is no adapter for the rear cause the slip join goes towards the diff. Obv the adapter that's wrapped up is for the transfer case I'm assuming. Just need some knowledgable eyes cause I'm having a brain fart.

 

No adapter for the rear. You need to replace the pinion yoke. The front has the adapter option. Do a little light reading on replacing the pinion yoke so you don't burn up your pinion bearing (preload).

 

Ok I'm aware of the preload just something about looking at this thing and being under the jeep it's not making sense. I'm sure once I start pulling this thing apart I will figure it out.

 

Hmm, can you take the wrapping off the yokes and take pictures? They don't look right, especially the rear.

 

Well got it all figured out and installed. Miserable experience getting the old one out. This shaft was designed to fit into the factory diff mount and I'm hoping I got it in there tight but I'm getting a nasty vibe. They are only Allen head bolts so torquing them is a knightmare do to the yoke being in the way. Anyone else ever used this style?

 

Nasty vibes huh? Do you have adjustable control arms to adjust the pinion angle in the rear.

 

I don't just RK coil wedges. Not thinking that's the issue as I had a very smooth ride before?

 

The wedges are for spring bow not to adjust your pinion angle.You need to adjust your control arms

 

Yeah the stock shaft uses a rzeppa joint on the rear too so angle doesn't matter. You need rear uppers at lest to correct the angle or you'll have issues for sure.

 

Well I know about the bow of the spring but thought they helped with the angle slightly. I know this is a newb question but what degree should I be looking for with new arms? Kinda curious what I'm at now to get a reference.
