In order to avoid expensive tire damage your steering must be aligned every 2 years or 24,000 miles. This is especially true with all the chuck holes in the road.
Tires that are already worn unevenly because of bad struts or shocks or because of a lack of tire rotation and balancing, must be replaced before we can perform an alignment. We can occasionally move the tires to a different position.
Before we can do an alignment we must inspect the steering parts and suspension to make sure there are NO LOOSE OR BENT PARTS. Most cars that pull or steer toward one direction have worn out steering or suspension parts, bad tires or a brake problem.
TIRES...They must have even wear so they will sit flat on the alignment swivel heads allowing for a quality alignment.
STEERING PARTS...The tie rods and steering rack or gearbox must be good to prevent the tires from wearing unevenly.
SUSPENSION PARTS ...Springs, struts and shocks must support the vehicle at the proper height, keep the tires on the ground and prevent floating or excessive bouncing. If the wheel bearings or steering rack are bad, the vehicle will make a growling noise and may cause the steering to stick in a turn.
