First and foremost...
WELCOME HOME and THANK YOU for your service!!:us:
Arms Heal? If you're in the Springs I'll be more than happy to loan you mine...anytime! Just let me know.
The nasty shake (AKA DeathWobble) can be caused by other items as well. Before spending any money a little more research may be in order. Out of balance tires can lead to DW and a bad alignment as well.
When exactly does the wobble occur? At any speed? Only while breaking? Going uphill? Downhill? Both?
I know it sounds crazy but mine only happened at 48-50MPH going slightly downhill or on level ground. Going uphill, even a slight grade, and it didn't shake at all. Mine was caused by really bad tire wear.
I recently replaced my trackbar with a Rubicon Express HD Trackbar and Drop Bracket. I got them from 4WheelParts for around $250 (I think).
