Why not simply install a aftermarket CV in fron drive shaft where it
connects to pinion? Given short drive shaft it is a viable long term
solution. Though some do it is is not advisable to rotate axle forward
and remove positive caster to improve drive angle a bit.

This is asking the obvious, but just in case:
Have you checked the front driveshaft if it is balanced?
The front driveshaft on the YJ isn't real short and I can't think that a 4"
lift is going to be enough to create vibes. I would check out the
driveshaft being balanced as well as the condition of the ujoints.

I agree the balance should be checked first along with the general
condition of the u-joints. A lot of jeeps have 4 inch lifts without
these vibrations coming up so there is a strong chance something else
is going on.
