Your stock busings are worn out on the control arms. The waggle you are experiencing is the tell tale warning sign that the rig is on the verge of death wobbling.
You can try playing with sabilizers, tire pressures, tire balance, etc etc etc, but in the end, your bushings will still be worn out, and the issue will re surface sooner or later.
Currie control arms are a nice upgrade and would ensure the issue doesnt come back.
