Nobody has mentioned the fact that the proper caster is required to make your Blazer track correctly, in addition to camber and toe-in. When you throw on a lift, the arched lift springs can rotate the axle position (via spring arch shape and/or built in degree shims) such that the pinion points further up towards the transfer case. This also rotates the steering knuckles in the same direction, reducing the amount of caster (in order to have positive caster the top of the steering knuckles must be leaned back behind the bottom of the steering knuckles). No amount of toe-in or camber will make up for a lack of caster. You will only be putting a Band-Aid on the problem and increasing tire scrub and wear.
