Your Wheel Alignment Questions Answered near Accoville, WV

At Thornhill GM Superstore, we understand a thing or two about alignment – and we don't just mean keeping your vehicle "on the line." If your vehicle feels ‘off,’ your steering wheel isn’t centered, or your tires are wearing unevenly, your alignment probably needs to be checked by professionals.

To help drivers near Accoville, WV, cut through the confusion, we've created a casual (but informative) FAQ covering our most asked alignment questions in our service bays.

Q: What’s the difference between two-wheel, four-wheel, and thrust alignment?

• Two-Wheel Alignment (Front-End): Adjusts only the front wheels. Common for older vehicles with a solid rear axle.
• Four-Wheel Alignment: Adjusts all four wheels. Ideal for modern vehicles with independent rear suspension.
• Thrust Alignment: A hybrid. Ensures the rear wheels are aligned with the vehicle’s centerline, then aligns the front wheels to match.

Which is right for you? Most modern vehicles benefit from a four-wheel alignment – but our technicians will recommend what your specific vehicle or truck needs.

Q: My steering wheel vibrates – bad alignment or unbalanced tire?

Great question. Vibration at certain speeds is usually a sign of tire imbalance, not alignment. But if the steering wheel pulls or drifts while driving straight – or if it isn’t centered when you’re driving – alignment could be the issue.

Still unsure? We’ll check both.

Q: My vehicle pulls to one side, but my tires look fine. Could it still be alignment?

Absolutely. Uneven tire wear is a classic sign of bad alignment, but you can have alignment issues before tire wear shows up. If your vehicle drifts left or right without steering input, it’s worth getting your alignment checked.

Q: How do worn suspension parts affect alignment?

Worn bushings, ball joints, or control arms can throw off your alignment and make it impossible to hold specs.

Here’s how:

• They create extra play in the system.
• Alignment angles can shift while driving.
• You may notice vague steering or extra road noise.

At Thornhill GM, we inspect suspension components before aligning – so we’re not just treating the symptom.

Q: What’s a “caster sweep,” and why does it matter?

The caster angle impacts the stability of your steering and the overall return-to-center feel of your vehicle. A caster sweep is how we measure that angle, typically turning the wheels a certain number of degrees in the alignment machine.

If your steering feels twitchy, doesn't return to center properly, or you're drifting at freeway speeds, then you may have a caster issue. Caster is an important adjustment included in the complete alignment service.

Q: My truck has a solid rear axle. Do I still need a four-wheel alignment?

Yes, in certain situations. Even if they can’t adjust the rear axle, four-wheel alignments help to make sure your front wheels are aligned with the rear "thrust line." This will result in better tracking, driving in a straight line, and no crab-walking.

Q: How do potholes and rough roads affect alignment?

West Virginia roads aren’t always kind to your suspension. Every pothole, speed bump, or curb hit can:

• Knock your wheels out of spec.
• Affect camber, toe, or caster angles.
• Lead to pulling, uneven wear, and poor handling.

Even one impact can create a minor misalignment that slowly gets worse – so don’t ignore that bump you felt last week.

Q: Will an alignment fix the steering wheel shake at high speeds?

It varies. If the shake involves tire wear from an alignment issue, new tires and a fresh alignment may fix the problem. Issues related to suspension or wheel imbalance will need to be dealt with directly.

That is why we conduct a comprehensive inspection to get to the root of the problem.

Q: What are subtle signs of misalignment?

Not all misalignment is severe. Here are a few indicators that may sneak up on you:

• You experience a minor pull when you’re driving on flat roads.
• Your steering wheel is not centered.
• You experience minor vibration after that little bump.
• You experience decreased fuel economy.
• Steering feels “loose” or “heavy.”

Address those early and save money on tires and suspension wear.
