03 TJ. 3.5" lift. CV driveshaft is pretty much crapped out. Is it a waste of time and money to replace it or should I bite the bullet and install a SYE eliminator kit and new driveshaft and adjustable rear arms. Gonna be like a grand to go that route. Do I have a choice?
Any recommendations would be appreciated also
I think you are right in your plan. If you are using a Tcase lowering kit, you can toss it too. I've had the SYE and double cardin for years and love the vibe free ride. I have adj. arms but you can probably wait for that. The lower arms set the diff in its correct position while the upper arms set the pinion angle. Adjustable uppers make it nice to get the perfect angle but may not be necessary if your pinion angle is ok with your current arms.
If I was doing it over again I'd go with the super short SYE to lengthen the DS a bit more.
