Your suspension keeps your tires in contact with the road, controls body movement over bumps, and works alongside your steering and alignment. Long Island roads — potholes, uneven pavement, stop-and-go traffic — put real wear on these components over time. Commack Auto Works diagnoses and repairs suspension issues for a wide range of vehicles.

Suspension & Strut Work
Common Suspension Symptoms
- Clunking or knocking noise over bumps or potholes
- A bouncy or unsettled ride, especially after dips
- The vehicle continuing to bounce after a bump instead of settling quickly
- Nose-diving when braking or leaning heavily in turns
- Uneven or premature tire wear
- Visible fluid leaking from a strut or shock
- Steering that feels loose, vague, or wanders on its own
- One corner of the vehicle sitting lower than the others
What's Involved in the Suspension System
Struts and shocks absorb impact and control how the vehicle's body moves over bumps. Control arms connect the suspension to the frame and allow the wheels to move up and down while maintaining position. Sway bar links and bushings help reduce body roll in turns.
Any of these components can wear out over time — bushings crack, links loosen, and struts or shocks lose their damping ability, all of which change how the vehicle rides and handles.
Diagnosing Suspension Noise
A clunk over bumps is one of the more common suspension complaints. It's usually traced to a worn sway bar link, a loose or torn bushing, or a strut mount that's no longer holding tight. We inspect the suspension under the vehicle and, where needed, test components by hand to find the source of the noise rather than guessing.
Suspension and Alignment Go Together
Replacing suspension or steering components changes the angles your wheels sit at, which is why an alignment is typically recommended after certain suspension repairs. Worn suspension parts are also a common cause of uneven tire wear, so addressing the suspension issue helps protect your tire investment.
Why Timely Suspension Repair Matters
Worn suspension components affect how well your vehicle handles, brakes, and holds the road — particularly in wet conditions or emergency maneuvers. Left alone, worn parts also accelerate tire wear and put more stress on nearby components.

Frequently Asked Questions
Why does my car clunk when I go over bumps?
This is often a worn sway bar link, a torn or cracked bushing, or a loose strut mount. We inspect the suspension to identify the specific source rather than replacing parts by guesswork.
Do I need an alignment after suspension work?
In most cases, yes. Replacing components like control arms, struts, or tie rods changes the suspension's geometry, so an alignment is typically needed afterward to set the angles back to specification.
Can bad suspension cause uneven tire wear?
Yes. Worn struts, shocks, or control arm components can change how the tire contacts the road, leading to uneven or accelerated wear patterns.
How do I know if it's my suspension or my alignment?
Noise over bumps, a bouncy ride, or visible leaking usually points to suspension components. A car that pulls to one side on a flat, smooth road without bumps often points more toward alignment — though the two are frequently related.
