Control Arm Front Inner Bushings

The Whiteline Performance Control Arm Front Inner Bushings (W0506) are engineered replacements for worn or deteriorated suspension components on 2008–2014 Subaru models. Factory rubber bushings naturally degrade over time, introducing play, harshness, and imprecision to front suspension geometry—especially noticeable during cornering and braking. These polyurethane control arm bushings restore lost stiffness and responsiveness, reducing unwanted flex that compromises steering feedback and handling predictability. Whether you're addressing worn OEM bushings or upgrading to sharper suspension tuning, this kit addresses a critical wear point that directly affects ride quality and vehicle control.

Whiteline's polyurethane-to-steel construction delivers a measurable step up from factory rubber in durability and performance. The steel inner sleeves anchor the bushing to the control arm mount point, while the polyurethane outer layer maintains damping characteristics and compliance—avoiding the harshness of full-solid aluminum alternatives. Polyurethane resists ozone, UV, and moisture degradation far longer than rubber, extending service life by years. The zinc oxide and black finish package protects against corrosion, critical for the front suspension assembly's exposure to road salt, moisture, and thermal cycling. Installation on these lower-inner positions is straightforward for equipped technicians, requiring standard suspension tools and proper torque specifications to factory standards.

Mechanics and DIY enthusiasts restoring worn Subaru suspensions benefit most from this kit's plug-and-play compatibility across 2008–2014 applications. The complete kit format eliminates guesswork about quantity and fitment, ensuring both left and right sides are addressed in one purchase. Owners noticing vague steering feel, clicking or clunking during turns, or excessive suspension movement under braking should inspect their control arm bushings first—this kit is often the direct solution. For those pursuing handling refinement beyond worn-part replacement, upgrading to polyurethane from factory rubber tightens suspension response as part of a broader chassis upgrade strategy. Proper installation using a press or bushing tool and adherence to torque specs is essential for longevity and safety.
