Control Arm Bushings

Control arm bushings are critical suspension components that isolate vibration and allow controlled articulation between the control arm and frame on your Toyota Prius. These polyurethane and steel bushings for the rear lower control arm (2019–2025 models) replace worn OEM rubber components, which deteriorate over time and cause clunking noises, loose steering response, and uneven tire wear. If you've noticed suspension play or heard knocking during turns or bumps, a worn control arm bushing kit is often the culprit—and replacement restores both comfort and handling precision.

This kit pairs polyurethane elastomer with a zinc oxide finish steel core, offering a significant durability upgrade over stock rubber. Polyurethane bushings resist oil degradation, UV damage, and extreme temperature swings far better than factory rubber, extending service life by 50,000+ miles in many applications. The zinc oxide coating prevents corrosion and maintains structural integrity under repeated compression and shear loads. Unlike purely rubber designs that compress and allow movement, polyurethane provides controlled compliance—dampening road feedback while maintaining precise geometry for consistent alignment and tire contact.

This rear lower control arm bushing kit is engineered specifically for 2019–2025 Toyota Prius models and installs with basic hand tools and a press or pickle fork. Mechanics and DIY enthusiasts performing suspension service, alignment work, or addressing suspension noise will find this kit straightforward to install; pressing out the old bushing and pressing in the new one typically takes 30–45 minutes per side. OEM Toyota suspensions benefit most from this upgrade when chassis mileage exceeds 80,000–120,000 miles, as factory rubber begins losing elasticity and allowing excessive play. The 1.22 lb weight per kit reflects a complete bushing assembly ready for direct bolt-on installation.
