Front end wheel alignment

Known as "Ackerman steering" the inside wheel turns more than the outside to reduce (or theoretically eliminate) scrub when turning. You should have to look pretty close to see the difference between the two sides, even at a steep turning angle, so if it's more pronounced then 'step back, stare at it a while, and pretty sure I can see a difference' check to make sure there isn't another problem (bad front end alignment, loose ball joints or bushings etc)
