Here is the beauty of the T&T truss. Unlike other setups that require you to pull your existing axle and take the Jeep off the road, T&T’s instructions walk you right through how to set everything up without the Jeep even being near the axle. Simply put the inner C at 5 degrees of negative caster, and then set the truss on the axle at 0 degrees. Tack weld the truss, double check your measurements, and burn it home. Alternate welding from side to side, allowing the welds to cool or you might warp your axle assembly with the heat.
