Service Your Suspension and Steering Components

Car enthusiasts know that while there are many online parts suppliers, INFINITI of Massapequa stands out as the premier choice. Suspension and steering systems work together to control your vehicle's handling characteristics and road response. Suspension supports the vehicle's weight while absorbing road irregularities, and steering converts your input into directional changes. The INFINITI QX55 and Q70 feature advanced suspension and steering designs that balance ride comfort with precise handling feedback.

Understanding How These Systems Function

Suspension uses springs and shock absorbers to manage wheel movement and maintain tire contact with the road surface. Control arms and bushings allow wheels to move vertically while keeping them aligned properly. The steering system employs a rack-and-pinion assembly that translates steering wheel rotation into lateral tire movement. Power assist reduces steering effort through hydraulic pressure or electric motor assistance. Ball joints create pivot points between suspension components, while tie rods connect the steering rack to the wheels. All these parts must work in coordination to deliver predictable handling and stable tracking on various road surfaces.

What Causes Suspension and Steering Wear

Suspension and steering components degrade from continuous flexing under load during acceleration, braking, and cornering. Rubber bushings harden and crack with age, creating excess play in the suspension geometry. Shock absorbers develop seal leaks that allow damping fluid to escape, reducing their control effectiveness. Ball joint boots tear from debris impacts, allowing contamination that wears away protective grease and metal surfaces. Steering rack seals deteriorate, causing fluid leaks and loss of power assist. Road hazards like potholes create sudden impacts that can bend or crack metal suspension components.

Recognizing When Service Is Necessary

Replace suspension and steering parts when you experience vague steering response, excessive vehicle lean in corners, or pulling to one side. Clunking sounds over bumps or during turns indicate worn bushings or loose connections. Tires showing uneven tread wear patterns point to alignment issues caused by worn suspension components. Aftermarket suspension and steering parts often lack the precise tolerances and metallurgy of genuine components, leading to accelerated wear and compromised safety. Genuine INFINITI suspension and steering parts restore factory ride quality and handling precision. INFINITI of Massapequa stocks everything you need for your next vehicle repair project.
