Shimming your rear axle may help some of the vibs from the rear Ujoint.
The front U joint will cause vibs too if it's not in line with the drive shaft and slip yolk.
Options are; dropped Tcase, raised motor mounts, or a double cardan front joint on the rear shaft.

The SYE it's self doesn't solve the vibration problem, the double cardan joint does.
a SYE is a good strong way to install a double cardan joint and a longer drive shaft, but the above shaft will eliminate vibes from the upper joint. It costs less, but you also get a shorter shaft. (But this isn't a TJ with the mini shaft)
And the double cardan solves upper joint vibes, but doesn't solve lower joint alignment which can also cause vibes.
