There is a write up somewhere that says put tape on both wheels in the front. Measure tthen roll truck to see tape on the back of the wheel. Measure. Adjust and repeat until about 1/16 to 1/8" Toe in. Good luck. This is on my to do list also. David
I performed alignment for many years at a Chrysler dealership. All vehicles that I checked specs for called for toe in, I set my own vehicles at zero to wear tires more evenly. The purpose for toe in is to assist in the steering wheel returning to center on its' own after a turn. Do what you like... I'm just throwing a penny worth of thought out.
Bc broncos has a good write up in their tech page
