An out - of - alinement car is a vulgar resultant of everyday driving . But the termalignmentdoesn’t really touch to your car ’s wheels , but rather to the suspension . As part of normal driving , parts of your cable car ’s break may become drawn , and spring can be stretched out . Even a little stroke or bumping a AMEX can disrupt your suspension , knocking some of the extremely - calibrated components off - kilter , and making your wheel baby-sit at wrong angles . An alinement restores these angle to their correct measurements , making sure that your wheels sit straight .
The most visible welfare of an alignment is less tyre habiliment . And when tires do fall apart down , they ’ll do so evenly on a decent ordinate suspension . Tires can be quite expensive — well $ 100 or more per tyre — whereas an alignment often costs $ 50 to $ 150 , making it a cost - in force process that should be part of even car maintenance [ source : Consumer Reports ] .

What Happens During an Alignment?
A car alignment is actually an elaborated process that bring the car ’s suspension into its proper configuration , lay and adapt component so that wheels are aligned with one another and the route surface . The alignment should be perform by an experienced mechanic , who uses an alignment machine .
unexampled coalition machines feature clamplike devices that are attached to the bike of the car ( which are raised up in the air ) and that link to a computing gadget that helps make exact measurements . The mechanic will also take this opportunity to verify that no abatement constituent are excessively worn or recrudesce .
An alignment essentially requires squaring a car ’s wheels and axles with each other so that they ’re move in the same instruction . The mechanic adjusts the various hanging angles — known astoe , thrust , camberandcaster — that influence tire trend and berth . The technician will also ensure that the steering bike is centered .
Each car ’s manufacturer designates standard angles for the alignment , specify in degrees . If you ’re a driver of a high - performance car or mutant car , your grease monkey may be capable to coordinate your suspension to improve treatment and tire carrying out , but such an alliance still may lead to uneven tyre wearing .
The type of alignment you receive will depend on your car ’s intermission . Afour - wheel alignmentis reserved for all - wheel drive vehicle or front - wheel campaign vehicles with independent or adjustable rear suspensions . In this instance , both axle have to be by rights aligned so that all four bicycle align in a rectangle , parallel to one another and perpendicular to the ground .
If you do n’t have a four - wheel or all - wheel drive vehicle , your car will likely only call for afront - end alignment , in which only the front - axle constituent or thrust angles are conform . Thrust angle concern to the slant that a car ’s rearward wheels point comparative to the railway car ’s center . In such an alignment , the rearward wheels and axle are realigned so as to be parallel with the front axle and vertical to the halfway line of the car .
After the alignment is complete , it ’s appropriate to ask for a printout that prove before and after images of the temporary removal alignment .
