Vehicle after running for some time, due to traffic accidents, road potholes caused by severe bumpy, especially at high speed suddenly encountered rough road, chassis wear and tear parts, chassis parts and replacement tires and other reasons will allow the vehicle to produce such tires abnormal wear, vehicle driving wandering, reduced safety, increased fuel consumption, accelerated wear and tear parts, steering wheel heavy, vehicle waving and so dangerous symptoms, and these symptoms may at any time give you driving dangerous.

Wheel alignment, positioning is diagnosed by measuring the angle of the vehicle if adverse symptoms and eliminate these symptoms. General family car to do the annual maintenance of the wheel alignment when it is necessary, and the vehicle under some special conditions frequently used to locate once every three months.

A car wheel alignment deviation must be done right?

Most drivers found the car deviation, the first reaction is considered to tire and suspension problems, and hurried to do wheel alignment. In fact, there are many reasons for deviation car, such as the degree of tread wear is not the same as would be wandering, suspension system design problems or injuries suspension, deformation, displacement, and so on.

1, ranging from tire pressure is an important cause of the deviation of the car.

Each twenty thousand kilometers should change of location of the tire, because the degree of wear of the drive wheel is always larger than the other wheels, different friction will directly lead to deviation.

2, a new car under normal circumstances due to the hoisting system failure, resulting in the deviation of the probability is very low, because the vehicle in front of the factory are factory rigorous testing and adjustments.

But they do not have the original design issues, such as guide-rod suspension and steering rod movement interference will affect the vehicle deviation. The former is due to the manufacturing error is generated due to the adjustment, which is caused due to the original design, and the latter cause deviation plurality right.

3. The steering system is good or bad will also affect the car straight.

Each connector gap is too large due to wear or bearing, king pin, bushing wear and tear caused by loose, causing the car to swing in motion, can not maintain normal trajectory. If the knuckle arm, a knuckle bending deformation, causing cars generally meandering way.

The most serious is the horizontal straight rod ball badly worn loose, it will cause the steering failure, when the car will be completely out of control.

4, then there is a different type of things that make you mistaken for car deviation.

In the high-speed car, the lateral deviation of wind can cause the car; had been leaning against the side of the road driving will cause deviation; low tire pressure can cause side deviation and so on.

Second, those things do wheel alignment should be noted:

Vehicle wheel alignment needs to be done and under what circumstances?

1, replaced with new tires or repair after a collision.

2, before and after unilateral partial tire wear.

3, the steering wheel while driving or floating heavy shaking.

4, when the car left or right deviation straight.

5, routine vehicle maintenance: a new car after driving for three months, after every six months or ten thousand kilometers to do a wheel alignment.

Normal wheel alignment after the vehicle will have the following improvements:

1, increase driving safety.

2, reduce tire wear is not normal.

3, when the steering wheel held straight upright, straight driving is maintained.

4, after turning the steering wheel will automatically Reformed.

5, increase the sense of control driving.

6, to reduce the fuel consumption of abnormal consumption.

7, the suspension member to reduce wear.

Wheel alignment is not exact consequences of what?

1, excessive tire wear: wheel alignment parameters are not accurate tire can cause uneven wear resulting in the risk of a puncture.

2, the vehicle does not open up easily: the steering wheel shaking and deviation will make you feel more tired to drive, while increasing the probability of accidents.

3, increased fuel consumption: If there are no special circumstances and fuel consumption increase, wheel alignment parameters of the vehicle may be inaccurate.

Third, teach you five strokes wheel alignment to prevent being cheated:

1, the instruments do wheel alignment, pay attention to make sure the maintenance depot qualified advanced positioning equipment.

2, vehicle data validation service personnel use your car is accurate.

Automotive increasingly updated data are updated and upgraded instrument positioning is often behind the times, according to some old and some new cars can only car to do some choose to locate. When you locate the best with a good description of the car, because there is accurate data of your car.

3, vehicle positioning after the completion of viewing the printed data.

Camber angle of the front wheels is within the standard range, not Mom, and Mom is not around, because this will cause your car deviation. After the dip in that only some special high-end car after inclination of about 8 degrees positive, because they have good power steering system. Toe-current high-end car rear wheel is adjustable, if the values ??differ too much from the standard that will also make your car deviation.

4, instead of the standard car chassis of the car, as some SUV, pickup, station wagon, etc., they are equipped with torsion bar springs, open time will cause the left and right vehicle height is inconsistent, this time you need to adjust the torsion bar up to standard values.

5, be careful not to put the car's high-profile car and factory standard values ??do not match, while the deviation will be low; too low to run up a whole will lose damping effect, too high will make your car run up a kind of Gone with the Wind the feeling, the most important thing is to pay attention not to the former high-low.

Fourth, correct wheel alignment erroneous concept of the owner:

1, that the wheel alignment is to adjust the front toe.

Wheel alignment, as the name suggests is the need to locate the state of the car four wheels must be considered. Toe angle is the concept, technically known as the toe angle.

In fact, not only the front wheel toe angle, and camber, caster angle, kingpin inclination. After the main wheels have positioned toe angle, and camber angle and propulsion. When the wheel alignment, wheel angle positioning is more important.

2, choose the cheapest shop wheel alignment, the problem can not be resolved.

Currently a large number of domestic and foreign production of wheel alignment companies competing to occupy the market, the production of various forms, of varying quality locator dazzling, no intellectual property rights and technical content locator manufacturers compete to lower prices.

In fact, in fact, because behind low-cost technical content and accuracy of measuring equipment is not high, this result is positioning of the vehicle can not be solved.

3, wheel alignment operation owners do not understand common sense, easy to be fooled.

Basically most users do not care about the operation of knowledge little is known about wheel alignment, wheel alignment done to the car when, rarely will put forward their views. Some owners do maintenance personnel will avoid wheel alignment, as well as maintenance staff before making positioning is not positioned before the examination, even the axle pouches, pouches under the arm hinge joint cracking can not promptly inform the owner, lead to future users greater losses, repeated positioning and repeatability of charge.

Summary: Do not underestimate the wheel alignment, the relationship between our driving safety. A four-wheel vehicle positioning data accurately can help us better car, reduce car costs to improve safe driving.
