I'm sure there is a proper spec in a manual somewhere...but I always set my 4x4 machines the same: zero toe. We all know that a bit of toe-in is better for control/steering....I go zero so that when in 4x4 with the front wheels pulling, it likely has a bit of toe-in. My 0.02.
how do you guys go about doing a alignment ?
Basically center your steering wheel and secure with strap if needed. Make sure quad is not jacked up. Measure from the center of the rear of the tires to the frame to ensure they are straight. Then measure from the rear tire to tire from the center line. Then measure from the front center to center for exact toe in or toe out depending on what your manual says. As stated you adjust tie rod ends to adjust. Hopefully thats somewhat clear ........ made sense to me lol. :d
