Why replacing suspension parts in pairs is a safety requirement
When your vehicle takes a hard hit to one side, components like struts, shocks, control arms, and coil springs absorb the impact. If the insurance company only authorizes replacing the damaged left-side strut, your vehicle will have one brand-new, stiff strut and one older, worn right-side strut. This uneven suspension stiffness causes unpredictable handling, uneven tire wear, and compromised braking performance under emergency conditions.
For a vehicle to perform exactly as the manufacturer intended before the crash, these components must remain balanced. We advocate for our clients to ensure that safety-critical parts are replaced symmetrically when required by OEM guidelines or standard automotive engineering practices.
Will insurance pay for both suspension parts if only one is damaged?
Insurers frequently refuse to pay for the undamaged side, claiming they are only responsible for direct physical loss from the accident. They attempt to classify the matching part as owner maintenance or preventative care. To overcome this pushback, we rely on three primary arguments:
- Manufacturer Guidelines: Many OEMs explicitly state that suspension components must be replaced in axle pairs to maintain proper electronic stability control and ADAS calibrations.
- Pre-Existing Wear: If your vehicle has mileage on it, putting a new strut on one side makes the car pull and handle unevenly, creating a driving hazard.
- The Right to a Safe Vehicle: Arizona guidelines expect insurers to return your vehicle to its pre-accident condition, which includes its safe handling characteristics.
How we get your insurer to cover matching suspension components
Overcoming an insurance denial for matching suspension parts requires objective technical evidence. We document the vehicle's alignment specifications, pull specific manufacturer repair procedures, and present a clear safety-based case to the adjuster.
If you were in an accident in Glendale, Peoria, or West Phoenix and your car handles differently, do not let the insurer cut corners on your suspension. Call Liberty Collision Center at (623) 931-2110 to get an independent, safety-first evaluation of your vehicle.
We do not sign contracts with insurance companies to join their Direct Repair Programs, meaning we answer to you, not their corporate cost-cutters. If your car needs paired suspension parts to be safe on West Valley roads, we fight for those parts.
