Rough alignment after front end rebuild

As mentioned, toe-in is most important. Toe-out will make the front-end wander dangerously. Too much toe-in will wear out the tires quickly. As the car ages, the front end sags, which changes toe-in (goes toe-out), so check/adjust height every few years and best to check/set toe-in after any height adjustment. For a quickie adjustment, hold a long 2x4 against each front tire and sight at the rear wheels. If the same track width as fronts (not always true), adjust until you spot ~1" off each rear wheel, and equal L & R (steering wheel centered). A bit easier on a FWD where you want slight toe-out and thus aim "on-tire" for the 1st tread channel on rears. Better is using a tape measure on the fronts, subtracting fwd from aft distance across tires (should be ~1/16" difference). Easiest if you have straight tread channels. Or use the "sight point on ground, fwd and aft" method above. Light is straight whether a fancy laser alignment machine or your view along a board.
