Performing a DIY alignment check on your car may seem like a daunting task, but with the right tools and guidance, it can be a straightforward process. This can save you a significant amount of money and time. It is also gratifying knowing that you can handle such a technical aspect of your vehicle. This article will guide you through the process of a DIY alignment check on your UK car using simple tools. We will break down the process into manageable steps and explain the tools you need. We’ll also provide some expert tips to help you get the job done correctly.
Understanding Wheel Alignment
Before diving into the actual process, it’s essential to understand what wheel alignment is and why it’s important. In simple terms, wheel alignment refers to the adjustment of a vehicle’s suspension. This is essentially the system that connects a vehicle to its wheels. When done correctly, wheel alignment ensures that your vehicle’s wheels are set to the car manufacturer’s specification, promoting optimal performance and longevity.

Wheel alignment is crucial for several reasons. Poor alignment can lead to issues such as uneven tyre wear, vehicle pulling to one side, and a crooked steering wheel when driving straight. It’s, therefore, a good practice to check your car’s alignment regularly, especially after driving over potholes or hitting a curb.
Tools Required for DIY Alignment Check
To perform a DIY alignment check, you’ll need some basic tools. You don’t need to invest in expensive, professional-grade tools to do a basic alignment check. Here’s a list of what you’ll need:

-
A Tape Measure: This will measure the distance between your vehicle’s wheels. Look for a tape measure that is at least 3 meters long.
-
Chalk or Masking Tape: You’ll need this to mark the centre of each tyre.
-
A String Line or Laser Level: This is used to check the alignment of the wheels relative to each other.
-
A Level Surface: This is critical for accurate measurements. A flat garage floor or driveway can work perfectly.
Steps to Perform a DIY Alignment Check
Now that you understand what wheel alignment is and have gathered your tools, let’s delve into the steps to perform a DIY alignment check.
Step 1: Prepare Your Vehicle
First, ensure that your vehicle is on a flat and level surface. Engage the parking brake to ensure the car doesn’t move during the check. It’s best to do this with a nearly empty fuel tank and no excess weight in the car.
Step 2: Measure and Mark the Tyres
Next, use chalk or masking tape to mark the centre of each tyre. You can find the centre by measuring the height of the tyre and dividing by two. Once you have all four tyres marked, you’re ready to proceed.
Step 3: Check Front Wheel Toe
The ‘toe’ refers to the angle of the wheels relative to each other when viewed from above. To check this, you need to measure the distance between the front and rear of the front tyres at the centre marks. If the distance at the front is less than the rear, your wheels have a ‘toe-in’ alignment. If it’s more, they have a ‘toe-out’ alignment. Ideally, both measurements should be equal, indicating a ‘zero toe’ alignment.
Step 4: Check Rear Wheel Toe
Repeat the process for the rear wheels. If there are significant differences in the measurements, it could indicate a ‘thrust angle’ issue, which means the rear wheels are pushing the car slightly to one side or the other.
Step 5: Check Wheel Camber
‘Camber’ refers to the angle of the wheel when viewed from the front of the car. A properly aligned wheel will be perfectly vertical. You can check this by using a straight edge (like a ruler or level) and a protractor. Place the straight edge vertically against the wheel, then measure the angle of the wheel relative to the straight edge.
Professional Assistance If Needed
Although a DIY alignment check can help you identify major issues, it’s worth mentioning that professional alignment services have the tools and expertise to perform more accurate and comprehensive checks. If you notice significant discrepancies or if the problems persist after adjusting your alignment, it’s recommended to seek professional assistance. Just remember, regular alignment checks are key to optimal vehicle performance and longevity.
Additional Tools and Pieces of Equipment
Next to the basic tools mentioned, several other equipment pieces can significantly simplify your DIY alignment process and enhance your precision.
-
Wheel Alignment Tools: These are specially designed tools that make it easier to measure and adjust wheel alignment. They include toe plates, camber gauges, and caster camber gauges. Toe plates help to measure the toe of front wheels accurately, while a camber gauge will help you measure the vertical tilt (camber) of your wheels.
-
Alignment String: This is a long and robust string that you can use to create a baseline from which to measure your alignment. By extending this string along the side of your vehicle, you can compare the position of the front and rear wheels.
-
Adjustable Wrench: You’ll need this tool to adjust your vehicle’s tie rods, which control the toe-in and toe-out angles of your wheels.
-
Vehicle Specs: The specific alignment angles will vary depending on your vehicle’s make and model. You can typically find these specifications in your vehicle’s service manual or online.
-
Procuring a Toe Gauge: A toe gauge measures the toe degrees of your car’s wheels. It’s particularly useful for checking whether your car’s front and rear wheels are parallel to each other.
Remember that safety is paramount when performing a DIY alignment, so ensure you’re wearing the right protective gear, including gloves and safety glasses.
How to Address Common Vehicle Alignment Issues
Understanding common alignment issues can help you better diagnose your vehicle’s alignment problems and know how to fix them.
Uneven tyre wear often implies improper wheel alignment. Notice the pattern of the tyre wear. If the inner or outer edge wears faster, it could indicate issues with toe alignment. If one side of the tyre wears more, it could be a camber issue.
A crooked steering wheel is another clear sign of alignment issues. If your steering wheel is off-centre when you’re driving straight, it indicates that your wheel alignment is off.
If your car pulls to one side, it could also mean there’s a problem with your vehicle’s alignment. This could be due to unequal tyre pressure, uneven tyre wear, or suspension problems.
Conclusion
DIY alignment checks could save you time and money. They are also a rewarding experience as you get to understand your vehicle better. The process only requires simple tools readily available in most garages, and the steps are easy to follow. However, remember to seek professional help if you encounter significant discrepancies or persistent issues even after adjusting your alignment.
Given the benefits of regular wheel alignment checks for your vehicle’s performance and longevity, it’s a good practice to learn the process. Even if you’re not experiencing any noticeable issues, regular checks can help you catch and address problems early. So, get your tape measure, chalk, string line, and possibly your camber gauge, and give your car a DIY alignment check. Your car will thank you for it.
Always remember: if you’re unsure or uncomfortable performing these checks, don’t hesitate to seek professional assistance. Safety should always be your top priority when dealing with vehicle maintenance.
