New guy here. I have a 90 4 runner that has had a SAS using Land Cruiser running gear. I am not sure of the year of donor axles but the front axle was coil sprung and square tube and the rear diff offset not centered. Trying to determine the Caster specs that the front axle should be set at. Using a magnetic bubble level tool set on 0 degree when wheels are straight I am getting a reading of just over 1 1/4 degree when wheels are turned to the 20 degree position, basically full turn to steer stop. I am wonder if I need more tilt. the pinion flange is measuring at 85.2 degrees with an electronic degree tool. Any input would be appreciated.
