I replaced my tie rod ends and did a toe-in alignment myself using a jig to measure fairly accurately the distance between the front and rear of the tires. Seemed t work fine. Then I replaced upper A-arm bushings and got new tires, so I had a shop align it. Tracks fine and the tires have worn fine, but the steering wheel no longer snaps back after cornering...at least not as it did. I forget which of the alignment functions influences this, but obviously they didn't do something quite right. Maybe when I take it back to them for inspection I'll ask them to revisit this.
