Question help vibration issues

i just had a 4.5 inch lift with all 8 adjustable CA's installed on my jeep, and i get some very low speed vibrations when turning i had this before the lift so i;m not sure if it is pinion angle or axle issues, also my front caster is at +2.8 and it wanders all over the place i know that with lifting comes some wandering but i think this might be a little too much

any thoughts the rear dana 35 has 150k on it possible it could be going out and causing the turning vibration but i'm not sure

Front caster should be 5-7 degrees with that amount of lift.
If you have a SYE your rear pinon should be tilted just above aligned with the drive shaft so when you put hard torque in it is pulling into aligned instead of out of aligned.
