A rough alignment can be done with simple tools before a trip to thealignment shop. Use a 24-inch carpenter's bubble level to check camberby placing the level flat against the tire. If the bubble is close tocenter, the car will handle safely. Improper camber can make a car feelscary. Use a tape measure to check toe-in. Measure from the center ofthe tires at the front, then do the same at the rear. A quarter-inchdifference in the measurements front to rear is safe and won't wear thetires excessively. Incorrect toe settings can cause tire wear as well,so checking the camber and adjusted toe is a must.
