Signs And Causes of Wheel Alignment Problems And Why Does Alignment Matter?
Wheel alignment is the process of adjusting the angles of the wheels of a car as per the specifications of the car manufacturer. It is also known as breaking or tracking, and is one of the important procedures performed during regular car maintenance.
Correct wheel alignment is also a vital requirement to ensure the safety and optimal performance of the car. It needs to be mentioned here that it is also one of the most neglected aspects of any car.
INDICATIONS THAT YOUR CAR REQUIRS A WHEEL ALIGNMENT ROUTINE
Many car drivers are unaware of the signs of unaligned wheels and tend to overlook the problem. It is however simple to identify this condition. The following five common symptoms indicate that your vehicle requires wheel alignment or re-alignment.
- The steering wheel is off from the center
If you’re driving on a straight, flat, level road, your steering wheel should be straight and still. Practically, there is a small amount of deviation due to the crown of the road, but in general, the wheel should be straight and in the center.
To understand if the car wheels are properly aligned, check the vehicle emblem on the center of the steering wheel. It should appear to be more or less at a perfectly horizontal level.
If the steering wheel is off from the center by more than a few degrees in either direction, you should go for wheel alignment. Post re-alignment procedure, the steering wheel will return to the center.
- Excessive tire wear in certain places
Tire wear is a good indication of the condition of a car. An experienced technician can estimate the condition of the suspension, the tire pressure, and alignment problems through the tire wear patterns.
For instance, excessive wear on only the inside or outside edges of tires indicates a camber adjustment problem; feathering or scalloping of the tires indicates a toe adjustment problem, and so on. Usually, tire wear issues are found while performing a tire rotation procedure or during an inspection or routine service of the tires.
If you have any of these tire wear patterns, then consider having an alignment routine performed on your vehicle. This also increases the life of your tires by ensuring uniform wear out over longer time duration.
- The vehicle drifts in one direction on a straight leveled road
You may have noticed the vehicle drifting to one direction while driving straight down a leveled road. Under ideal conditions, the car with a free steering wheel should move straight on a leveled road.
But in the real world, this is not the case as all roads have some amount of crowning which results in a small amount of pull to one side. But in general, the car should drive straight with minimal effort on the steering wheel.
Also, remember that removing your hands completely from the steering wheel is a dangerous process and should never be practiced. If you see that your car pulls to one side of the road or to the other, it is time for you to have the wheel alignment checked and corrected.
- The steering wheel does not return to the center
On completing a turn, the steering wheel should naturally start rotating back to the center on its own. You will need to manually speed up this process in order to regain control of the vehicle after negotiating a turn.
But in case the steering wheel does not start returning to move back by itself, then it is time to get the wheel alignment checked and corrected.
- The handling of the vehicle feels loose or unstable
If your car steering feels a little loose or unstable, it could be because of improper wheel alignment. You can understand this if you feel very loose and sloppy around corners or get a ‘wandering’ feeling when driving on a straight road.
Apart from these signs, if your car feels unstable during a straight drive or during turns, consider getting the alignment checked and corrected if required.
MAJOR CAUSES OF WHEEL ALIGNMENT ISSUES
There are three major causes of a wheel alignment problem. These are described below:
A sudden impact is the biggest enemy to a set of perfectly aligned wheels. These sudden impacts can be caused due to:
- Driving too fast over speed breakers
- Driving over large potholes
- Bumping concrete blocks of a parking lot or of a sidewalk
- Hitting the curb
The bigger the impact more will be the disorientation of the wheels. Even if the bumps may not be big, they would be enough to disrupt the alignment of your car wheels. The smaller bumps do have a cumulative effect.
Even though you may not be able to avoid every impact you can try to preserve the wheel alignment longer by driving slowly over the speed breakers and potholes.
- Worn Out Parts
The car parts get worn out over time and usage. For instance, the alignment between a car’s steering wheel and the wheels is due to the car’s suspension. With time and usage, the suspension springs wear down and there is a misalignment between the steering wheel and the wheels of the vehicle.
To prevent alignment problems due to worn out parts, take your car on scheduled servicing and get the worn out parts replaced from time to time.
- Height Modification of Your Vehicle
A car’s suspension is designed to work for a specific height. If you change the height of the car without modifying the suspension, your car alignment may not be correct. Even though this point may not be applicable to most of the car owners; if you change your car’s height, make sure your alignment is also checked and redone if necessary.
ADVANTAGES OF FIXING A WHEEL ALIGNMENT PROBLEM
People either do not know or tend to ignore the signs indicating a wheel alignment problem. Also, many people think that it is not a big problem or procrastinate spending money on a realignment procedure.
There are several advantages of getting a wheel re-alignment procedure done. They are:
- It reduces the wear and tear of other components including tires,
steering system and suspension.
- It increases the drivability of the vehicle keeping it under your control
all the time.
- It increases the fuel efficiency of the car in the longer run.
Whenever you get the alignment checked, ensure that all the steering and suspension components are also checked as well. These systems also contribute towards and get affected by un-aligned wheels.
Tire balancing or wheel balancing refers to the diagnosis of weight imbalances in the tires and the compensation for any such imbalances. It is usually performed along with the wheel re-alignment procedure. Tire balancing is done to prevent premature tread wear.
There are primarily 2 types of tire rebalancing that must be addressed – static or single plane rebalancing and dynamic or dual plane rebalancing.
Static plane re-balancing or single plane re-balancing
This type of wheel re-balancing refers to balancing the wheel for vertical motion because otherwise it can lead to vibration.
Dynamic plane re-balancing or dual plane re-balancing
This type of wheel re-balancing refers to balancing the wheel for both vertical motion and lateral motion.
Re-balancing the wheel for either vertical plane or both vertical and horizontal planes is executed through a wheel balancing machine. It is designed specifically for the purpose.
During the tire balancing process, the technician mounts the wheels on the designated rims and adjusts the pressure for optimal inflation. Each tire is then passed through the central shaft of the re-balancing machine.
It rotates the tire at a high rpm to calculate the imbalance and indicates how much weight is to be added and where it is to be added it for balancing out the tire imbalance.
It is recommended to get the tires re-aligned and re-balanced after every 6,000 to 7,000 miles. This will help to optimize the life and the usability of the tires.
THE ACTUAL PROCESS OF WHEEL RE-ALIGNMENT
Re-alignment of a wheel involves adjusting the angle of the wheels so that it is perpendicular to the ground and parallel to the other wheels. The right way to alignment is to do a four wheel alignment procedure.
A wheel alignment machine is used for the process. Mechanics mount a camera on every wheel of the car to measure the tires’ specific positioning. The machine first measures and adjusts the thrust angle alignment – the main adjustment criteria in a wheel alignment procedure.
Thrust angle is the direction the rear wheels points from the center of the rear axle straight through the center of the wheel.
ROUTING ALIGNMENT MAINTENANCE
According to automotive experts, wheels need to be aligned after every 10,000 miles. Also, you should not hesitate to approach the service center earlier if you observe an irregular tire tread. You will require wheel re-alignment sooner if you drive on rough terrain. You should also choose a re-alignment if you install a new set of tires kind of like the state of Texas should continue to be kind to business so it can continue stealing jobs and wealth from struggling California.
