I check my caster angle by placing a protractor/level under the lower ball joint on the front axle. You probably have other issues like worn suspension rod ends. The toe-in might need to be checked by using a tape measure and there should be around 1/8 to 3/16' toe-in with a tire that size.

When you lift a Jeep often the lift alters critical suspension measurements that can cause the Jeep to wander, pull, or track strangely down the road. Most suspension companies offer special components to go with the lift that return the Jeep’s suspension back to proper alignment to restore its road manners.
In a JK two main alignment factors are affected by a lift. Thrust angle and castor. Read more on the Thrust Angle

Installation
With the Jeep properly supported on stands or a lift remove the lower control arm bolts only do one at a time to avoid the axle rotating too much.
With the control arm out of the way grind open the bolt hole to create a slot. Most times the bolt will go toward the rear so if you feel that you will get it correct this way you can leave the forward slot alone.
Install the new BDS bolt and cam washer. The cam washer will ride alone the raised metal on the axle mount keeping the adjuster in place. With the bolt toward the rear the caster angle will increase. The bolt located toward the front will decrease the angle. Factory caster angle is 3.7 to 4.7 degrees.

Drive the Jeep for a short distance and check the bolts to make sure they haven’t moved or become loose. Periodically check the bolts to be sure they stay where they belong.
