Have you ever wondered, “Why is my steering wheel not straight after alignment?” It could be due to several factors, such as worn suspension components, uneven tire wear, or a misaligned subframe. Other potential causes include bent steering components, incorrect toe settings, issues with the steering rack, or simply an improper alignment. If your steering wheel is misaligned, seek another professional inspection immediately.
Are you frustrated with your steering wheel not being straight even after an alignment? It happens; sometimes, it’s because the alignment wasn’t done properly, or your steering wheel is misaligned for other reasons, such as worn suspension components, uneven tire wear, or even a weight distribution issue caused by a bent or damaged subframe. This article discusses some possible reasons why your steering wheel might not be straight after alignment.
Incorrect Alignment Settings
The alignment process may not have been performed correctly, leaving the steering wheel off-center. While it’s not likely, it does happen – especially if it’s a DIY job.
With the right tools, anyone can attempt to realign their wheels – a few angle measurement devices, a level, and a few pieces of string can be used as a makeshift alignment setup. However, even a minute error can result in an off-center or vibrating steering wheel, especially at higher speeds. Be sure to use your manufacturer’s recommended alignment settings and consider an electronically measured alignment at an auto repair shop.
Uncalibrated Steering Angle Sensor
The steering angle sensor may need recalibration to align properly with the steering wheel. It is one of countless sensors that your car’s computer uses to ensure a smooth ride.
Car manufacturers each have their own proprietary stability system that relies on such sensors to assist with steering or improve traction.
An uncalibrated, malfunctioning, or dying steering angle sensor might cause your steering wheel to act strangely even after an alignment, including heavy steering and off-center driving (especially for cars with fully electric steering).
Worn Steering Components
Outside of electronic malfunctions, hydraulic or traditional power steering systems consist of countless moving parts. Parts like tie rods, ball joints, or bushings might be worn out, causing the steering wheel to be misaligned. This can cause an off-center steering wheel even after getting your wheels re-aligned.
Uneven Tire Wear
A perfect DIY alignment job might ensure that your rims are in the proper position relative to the suspension, but subtle uneven tire wear caused by previous misalignment can be hard to spot on a stationary vehicle if you don’t know what you’re looking for.
Tires that are unevenly worn can cause the steering wheel to pull to one side even after alignment. It’s crucial to get your tires changed if they’re worn out unevenly—at higher speeds, uneven tire wear can create a dangerous pull on your steering in one direction or the other or cause a lack of traction.
Bent Steering or Suspension Parts
A realignment of your suspension can quickly come undone if the suspension itself is damaged. Damage to components from a pothole, curb, or accident can lead to an off-center steering wheel due to minor bending of the struts and other critical components.
If your car is frequently subjected to bad road conditions, it’s important to get its alignment and suspension inspected every few years.
Improper Tire Pressure
Uneven tire pressure can affect alignment and steering wheel position. This is a simple fix—reinflate your tires as per your car manufacturer’s specifications. Air pressure specifications usually vary for each axle and can differ depending on whether you frequently haul cargo or use winter, summer, or all-weather tires. Be sure to match your air pressure accordingly.
Cross-Camber or Cross-Caster Issues
Camber refers to the angle of the wheels in relation to the vertical axis of the car when viewed from the front. Positive camber means the top of the wheels tilt outward, while negative camber means they tilt inward.
Caster is the angle of the steering pivot when viewed from the side of the vehicle. It affects the vehicle’s stability and steering effort. A positive caster tilts the steering axis toward the driver, while a negative caster tilts it away.
Differences in camber or caster angles between the wheels can cause the steering wheel to be off-center. This usually occurs after an improper alignment or when damage to the suspension causes misalignment.
Frame Damage
Structural damage to the vehicle’s subframe can affect alignment and steering. Your frame is the skeleton of the car, mounted on the chassis and covered by your car’s body. Modern car frames are designed to crumple after a severe impact, absorb most of the force during a car accident, and spare the driver.
While a fender bender might not do any serious structural damage to your car, minor accidents can still bend the frame out of shape, which changes your car’s weight distribution and can greatly affect your safety in the event of another accident. Changes in weight distribution caused by structural damage may cause your car to veer faster.
Loose Steering Column
If the steering column is not securely attached, it can cause the steering wheel to be misaligned. This can occur on older cars especially—over the course of many miles and many years, the brackets holding the column in place may become loose as the car’s vibration slowly undoes the bolts.
Conclusion
If you’re wondering why your steering wheel isn’t straight after an alignment, it could be due to various factors. An incorrect alignment is possible, especially if there is a mistake in the alignment settings. Uncalibrated steering angle sensors, worn steering components, or damage to the suspension are other common potential explanations.
Other potential issues include uneven tire wear, bent parts, improper tire pressure, or frame damage. It’s essential to seek a professional inspection to identify and address the root cause promptly – ignoring the warning signs can be especially dangerous and may result in serious damage to your car or yourself.
