You hit a pothole on Route 28 hard enough to make the cabin shudder. The car still drives. The dash didn't light up. So you keep going. A week later the steering wheel sits a little crooked. A month later you're paying for tires and an alignment instead of one or the other. This is how almost every pothole damage repair in southern New Hampshire starts — small, ignorable, and progressively more expensive.
Late winter through May is the worst stretch for it. Snowmelt runs into pavement cracks, refreezes overnight, expands, and breaks the road open. By the time DOT crews patch the bad spots, thousands of cars have already taken the hit. At Vorenza Auto Repair in Derry, we see a clear seasonal spike in alignment, suspension, and rim work every spring — and the drivers who catch problems early always pay less. Below are the five things we look for in a pothole damage inspection, with what each one likely means and roughly what it costs to fix.
1Vibration or pulling at highway speed
→The wheel buzzes or the car drifts
A new vibration that shows up between 50 and 70 mph — right where I-93 traffic between Manchester and Derry usually sits — is the most common pothole signature we see. So is a steady drift to one side when you let off the wheel on a flat road.
What it usually means: a bent rim throwing the wheel out of round, a knocked-out alignment angle (toe or camber), or both. Bent rims are easy to confirm visually on a lift; the rest needs a four-wheel alignment rack.
What to do: book a wheel and alignment inspection before you replace tires. Driving on a misaligned car will scallop a fresh set of tires inside a few thousand miles, which is real money for any commuter.
2New clunks, knocks, or rattles over bumps
→Suspension noise that wasn't there before
Hit a deep pothole and the suspension is the shock absorber for everything the tires can't handle. A hard impact can dent a strut, crack a control arm bushing, or loosen a sway-bar end link. The first symptom is almost always a new noise — a metallic clunk over expansion joints, a rattle at low speed, or a soft thump when you turn into a parking spot.
What it usually means: blown strut, bent control arm, broken sway-bar link, or a leaking shock. Some are minor; a damaged strut can compromise braking distance, especially when the road is wet.
What to do: get the suspension looked at before another big hit turns a $150 part into a multi-component repair. We cover this on our general auto repair page.
3Tire bulge, sidewall blister, or sudden slow leak
→The sidewall doesn't look quite right
This is the only one on the list that's an immediate safety issue. When a pothole pinches the tire against the rim, internal cords inside the sidewall can break even if the tread looks fine. The pressure pushes outward through the broken layer and forms a soft, squishy bulge — sometimes the size of a grape, sometimes the size of a golf ball.
What it usually means: the tire is one bad bump away from blowing out at speed. There is no patching it. A spare or roadside tire change is the only safe move.
What to do: if you spot a bulge or a new slow leak after a pothole hit, get the tire replaced before your next trip. Walk around the car and squat down by each wheel for thirty seconds — it's the best two-minute check you can do as a driver.
4Steering wheel off-center or vague feel
→You're holding the wheel slightly to one side
On a flat, straight road your steering wheel should sit dead center. If you find yourself holding it five or ten degrees to one side just to drive straight, the alignment is out. After a winter of potholes that's expected, but the cause matters — sometimes a quick toe adjustment fixes it, sometimes a tie rod or strut mount has shifted and needs a part replaced first.
What it usually means: alignment out of spec, possible tie rod end damage, or worn ball joint exposed by the impact.
What to do: a four-wheel alignment with a parts inspection before the rack is set. Skipping the inspection and aligning a worn front end is a waste of money — the angles will drift right back out.
5Visible curb rash, a bent wheel, or fluid spots in your driveway
→Something looks or smells wrong under the car
The last sign isn't one symptom — it's the morning after a hard hit. Take a slow walk around the car in good light. Look at each wheel for a flat spot or chunk of rim missing. Look under the car for new oil, coolant, or power steering fluid spots. Smell for burnt oil after your drive home.
What it usually means: a cracked rim that won't hold a seal, a punctured oil pan, a bent skid plate, or a leaking power steering line that got pinched on impact. These are the repairs that escalate fastest if ignored — a slow oil leak becomes a spun bearing, a coolant leak becomes a head gasket.
What to do: get it on a lift the same week. Our diagnosis service covers leak inspection, and our maintenance team handles the multi-point inspection that catches all five of the signs in this list at once.
What a pothole damage inspection costs at Vorenza
We don't believe in mystery pricing. Here is what most southern New Hampshire drivers spend after a rough pothole season — and the parts of it we publish on the site directly:
Real numbers, posted up front.
- Oil change: starting at $89.95 — up to 5 quarts included, $8.95 per quart after. Spring oil changes pair well with a courtesy multi-point inspection that catches pothole damage before it grows.
- Brake pads & rotors: starting at $299 per axle. Hard braking on rough roads accelerates pad wear; we'll inspect free if you're already in the bay.
- Suspension, alignment, tire, and rim work: custom quote based on your vehicle and what the inspection finds. We give the estimate before any wrench turns — no surprise charges, ever.
How to drive smarter through pothole season
You can't dodge every hole on Route 102, but a few habits cut down on damage:
- Keep tires at the door-jamb pressure, not the max sidewall pressure. Properly inflated tires absorb impacts better and protect rims.
- Don't brake into a pothole. Brake before, then release as the wheel passes over — a rolling tire takes a hit better than a locked one.
- Watch the puddles. In April and May a puddle that looks shallow is often a 4-inch crater. Slow down rather than guessing.
- Get spring maintenance done early. A worn shock or thin pad turns a survivable hit into a bigger repair.
If you're already past one of those signs, that's fine — the point of an inspection is to catch the rest before they compound.
