That's right today it is about Alignments 
Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel is off center, you have uneven tire wear or your car doesn’t feel like it handles right. When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin.
Driving for an extended time when you're out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You'll have to replace your tires sooner, but even worse - you may cause premature wear to your suspension system, which can be really expensive.
The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ways. The first adjustment is called toe. The next adjustment is called camber. And finally, there is castor. The engineers who designed your vehicle determined the alignment settings that will give you the best handling and safety.
There are several things involved in an alignment check. First, there's an inspection of the steering and suspension - it should be checked to see if anything's bent or broken. Then the tire condition needs to be inspected. From there, the vehicle is put on an alignment rack and an initial alignment reading is taken. If all four wheels are adjustable, they are lined up perfectly parallel with the vehicle's center line. If the back wheels aren't adjustable, a technician at Allied Auto Works can determine the direction they push and then aligns the front wheels to match.

Like most things, your manufacturer has suggested a mileage interval for having your alignment checked. But if you run into a curb, pothole or something else that's given you a big jolt, pay attention to whether your vehicle is pulling to one side when you drive. It's better to have your alignment checked before waiting to see if there is uneven tire tread wear - by then, the damage is done.
Getting your alignment checked when needed is a great way to extend the life of your tires and suspension parts. It also makes sure that your tire meets the road properly for maximum performance and safety.
