Suspension symptoms
- Clunking or knocking over bumps, railway crossings or speed humps. This is often sway bar links, ball joints or strut mounts.
- Bouncing or floating after a dip, or the nose diving hard when you brake.
- Leaning or swaying in corners and on Highway 404 or Highway 407 ramps.
- Humming or growling that rises with speed, often a wheel bearing.
- Loose or wandering steering, or a clunk when turning.
- Uneven or cupped tire wear (scalloped patches around the tread).
- One corner sitting lower than the others, which can mean a broken coil spring.
- Oily residue on a shock or strut body, a sign it’s leaking.
Suspension components we repair
Shocks and struts
They control how the springs move. Worn ones increase stopping distance, cause bounce and wear tires faster. Struts also support the vehicle’s weight and affect alignment. We usually recommend replacing them in pairs across an axle so the car handles evenly.
Control arms, bushings and ball joints
These locate each wheel. Cracked bushings or a loose ball joint cause clunks, wandering and uneven tire wear. A badly worn ball joint is a safety issue.
Tie rod ends
These connect the steering to the wheels. Play here shows up as loose steering and feathered tire wear.
Sway bar links and bushings
These are the most common source of a clunk over bumps, and usually a straightforward fix.
Coil springs
Road salt corrodes springs over time, and they can snap, often in cold weather. A broken spring can damage the tire beside it.
Wheel bearings and hubs
A worn bearing hums or growls and can set ABS warning lights, because many hubs carry the wheel speed sensor.
Pothole and collision damage
Thornhill’s spring pothole season is hard on suspensions. A single sharp hit can bend a control arm, crack a strut mount or knock a tie rod out of shape. Our pothole damage inspection guide explains what to check afterwards.
Collisions, especially a wheel strike into a curb or another car, can bend suspension parts that look fine. Read can a collision affect wheel alignment or suspension? and what hidden damage after a car accident looks like. We measure mounting points on our frame machine when needed. When the damage is part of a claim, we include it in the collision repair estimate and bill your insurer directly.
How we inspect your suspension
- Road test to hear and feel the complaint.
- Hoist inspection: check each joint for play, look for leaks, cracked bushings and broken springs, and spin each bearing.
- Tire wear check, which often points to the worn part.
- Written findings and quote, separating urgent safety items from parts that are wearing but still OK.
Alignment after suspension work
Replacing struts, control arms or tie rods changes alignment angles. We finish those jobs with a wheel alignment, and with ADAS calibration when your vehicle’s steering and camera systems need it.
Suspension and your safety inspection
Worn ball joints, tie rods, broken springs, leaking shocks and excessive bearing play can all fail an Ontario safety inspection. As an MTO-authorized station, we inspect and repair in one visit.
What affects the cost
Which parts are worn, whether struts are sold as complete assemblies for your vehicle, seized or rusted hardware, and the alignment or calibration needed afterwards all affect the total. Call 905-886-2737 for current pricing.
Areas we serve

Suspension repair FAQs
How do I know if my shocks or struts are worn?
Watch for bouncing after bumps, nose-diving when you brake, leaning in corners, cupped tire wear, or oily residue on the shock or strut body. Worn shocks and struts lengthen stopping distances and wear tires faster. We road-test and inspect on a hoist, then show you what we found before quoting.
What causes a clunking noise over bumps?
The most common causes are worn sway bar links, ball joints, control arm bushings or strut mounts. Loose exhaust heat shields can also rattle. Some of these are simple fixes; a loose ball joint is a safety concern. We locate the exact source on a hoist so you’re not paying for parts that weren’t the problem.
Should shocks and struts be replaced in pairs?
Yes, usually. Replacing both sides on the same axle keeps handling and braking even from left to right. A new strut on one side and a worn one on the other can make the car feel unbalanced. If only one side was damaged in a recent collision with low mileage, we’ll discuss whether a single replacement makes sense.
Do I need an alignment after suspension repair?
Usually, yes. Replacing struts, control arms or tie rod ends changes the alignment angles, and skipping the alignment can cause pulling and fast tire wear. We do the alignment in-house after suspension work, plus steering angle reset or ADAS calibration when your vehicle requires it.
Can a pothole damage my suspension?
Yes. A hard pothole hit can bend a control arm or tie rod, damage a strut, crack a rim or knock the alignment out. If the car pulls, the steering wheel is crooked, or you hear new noises after a hit, book an inspection. Catching damage early prevents ruined tires and further wear.
Will worn suspension fail an Ontario safety inspection?
It can. Excessive play in ball joints or tie rods, broken springs, badly leaking shocks, worn bushings and loose wheel bearings are common reasons for failing. We’re an MTO-authorized inspection station, so we can inspect, repair and complete the safety inspection in one visit. Call 905-886-2737 for current pricing.
