Taunton commuters navigating Route 24 face extreme suspension stress from post-winter potholes and high-speed bridge transitions. A hard impact at highway speeds can slide alignment bolts or bend aluminum components, leading to rapid tire wear and compromised safety. Simon’s Auto Repair offers precision high-speed alignments to defend your vehicle’s durability.
The high-speed corridors of Bristol County are unforgiving to even the most robust suspension systems. While a pothole on a local street might be a nuisance, hitting a crater at 70 mph on Route 24 is a violent mechanical event that can instantly knock your vehicle out of specification. At Simon’s Auto Repair, we specialize in identifying the hidden damage that highway commuting causes, ensuring your car remains stable and your tires last through the season.
High Speed Impacts and the Physics of Alignment Shift
A strike at highway speeds is a high-velocity energy transfer. When your tire hits a sharp-edged crater near the Raynham line, the force is a massive horizontal jolt that travels through the wheel and into the suspension mounting points.
- Eccentric Bolt Slip: Most modern vehicles use offset washers to hold alignment settings. The sheer force of a Route 24 impact can physically slide these bolts out of their green zone.
- Tire Scrubbing: Even if your car still feels straight, a shifted bolt causes the tires to scrub across the asphalt at 100 feet per second, shredding tread in weeks.
- Energy Transfer: The jolt doesn’t stop at the tire; it moves into the rack and pinion, often causing subtle internal damage that leads to steering dead zones.
Bent vs Misaligned and Identifying Structural Damage
Modern automotive design has shifted toward lightweight aluminum suspension arms. While aluminum improves fuel efficiency, it lacks the elastic memory of the heavy steel found on older cars.
- Aluminum Deformation. If an impact is violent enough to bend an aluminum control arm, the part will not spring back to its original shape.
- Tie Rod Elasticity. Potholes can stretch or slightly bow a tie rod without snapping it, changing the mechanical length of your steering system.
- The Steering Signal. If your steering wheel is now off-center by a few degrees, it is a clear signal of structural change that a standard alignment adjustment cannot fully mask.
The Taunton Commuter Protocol for Highway Speeds
High speeds amplify every minor error in your suspension’s geometry. A toe-out error that is unnoticeable at 20 mph becomes a major stability hazard when fighting crosswinds near the Route 140 interchange.
- Thrust Angle Precision. We ensure the rear wheels are perfectly squared to the front so the car doesn’t dog-track.
- Caster Stability. Proper caster settings prevent the car from feeling floaty or nervous at 65 mph.
- Driver Fatigue. A precisely aligned car requires fewer micro-corrections, making the 45-minute trek to Boston or Providence much less taxing.
Simon’s Precision Inspection and Beyond the Computer Screen
Standard fast-service shops rely entirely on what the computer screen shows while the car is sitting still. At Simon’s Auto Repair on Somerset Ave, we know that a computer can be fooled by worn-out rubber.
- Dynamic Bushing Test. We use a high-torque pry bar to check for delamination in the rubber.
- Static vs. Load. A car might look perfect on the rack, but the moment you brake hard or change lanes, torn bushings allow the wheel to walk out of position.
- Visual Evidence. We inspect for feathering or cupping on the tire tread—physical proof of how the car behaves under load.
Safety First and Emergency Collision Defenses
Your alignment is the foundation for your car’s Advanced Driver Assistance Systems (ADAS). Your Lane-Keep Assist camera and Automatic Emergency Braking sensors assume that the mechanical zero point is accurate.
- Sensor Conflict. If you are holding the wheel at an angle to stay in your lane, the car’s computer sees a conflict between the steering input and the vehicle’s path.
- Safety Net Shutdown. This mismatch can cause safety systems to disable themselves during a heavy April rainstorm on Route 24.
- Emergency Swerving. A misaligned car may over-rotate or wash out during a sudden lane change to avoid debris, as the suspension is already fighting itself.

Frequently Asked Questions
Is it normal for my car to vibrate only above 60 mph?
Yes. This is often a sign of a high-speed alignment shift or a tire that has developed a diagonal wear pattern from a recent pothole strike. It indicates the wheel is fighting the road at higher rotational speeds.
Can a pothole ruin my tires even if the car still drives straight?
Yes. If both front wheels are knocked out by the same amount, the car won’t pull, but the tires will be under constant stress. The inner edges of your tires can be shredded in as little as 500 miles of highway commuting.
Will an alignment fix the thud I hear over bumps?
No. A thud usually indicates a broken strut, failed ball joint, or torn bushing. We must replace the damaged hardware first, as these parts are what hold the alignment settings in place.
Is a floaty feeling when changing lanes on Route 24 a classic symptom of rear-wheel misalignment or worn bushings?
Yes, this is a classic symptom of rear-wheel misalignment or worn bushings. When the rear axle is not squared to the front, the car feels like it is swaying or taking a moment to settle after a steering input.
Should I get an alignment if I hit a pothole but don’t see damage?
Yes. Modern aluminum components can bend or stretch just enough to ruin your tires without showing obvious cracks or breaks. A quick check at Simon’s can save you the $1,000 cost of a new set of tires later this month.
