Is wheel alignment accurate?
How do you know your car wheel alignment is accurate?
You may notice the following alignment issues:
Uneven tyre wear is caused by improper alignment, over-inflation, under-inflation or a worn-out suspension. Improper alignment means a vehicle is not aligned with OEM’s alignment specification, it is caused by bad alignment and gets the tyre wear.
The steering wheel is crooked when you are driving straight:
When your wheels are not aligned properly, you will notice that your steering wheel is off-centre, i.e. the logo is not straight. You may be driving straight but your vehicle keeps going to the left or the right, leaving you with the headache of correcting it constantly. Your tyre tread might also wear down unevenly because the misaligned wheels are bouncing up and down on the road’s surface.
Noisy Steering:
When you turn a steering wheel, the tie rods enable the wheels to move in response. A loose or damaged tie rod will create a knocking, clunking, or creaking sound it is especially true when you turn at lower speeds. It may even cause your steering wheel to be off-centre.
The steering knuckles and control arms can sustain movement with the help of ball joints. These joints need lubrication to prevent themselves from going dry.
Pulling to the right or left:
The most common reason for a car pulling to one side is incorrect wheel alignment. If this is the case, when you release the steering wheel, the car will drift in one direction and the steering wheel is unlikely to return to its normal position.Unfortunately, getting the car’s wheels re-aligned with the correct tyre pressure won’t always solve the issue of it pulling to the left or right. If you still experience pulling, the echnician might not have taken the road ‘crown’ into account. Essentially, the crown is a slope that allows for drainage. When roads are built engineers never build them flat; this enables rain to run off and reduces the risk of flooding.
Far more likely is that there is a worn suspension or steering part. If that is the case, no matter how much the wheel alignment is reset, the vehicle will continue to pull to one side. In this instance, it’s always best to get a qualified mechanic to have a look.
Squealing tyres:
Wheel alignment can also be a plausible reason why your brakes are shaking and squeaking. If the wheels are not aligned suspension and tyres will eventually become especially vulnerable to damage. Have your wheel alignments checked and your tyres rotated every 5,000 miles.
