This 4-piece Front Lower Control Arm Bushing Kit from AUTOACER is designed for the Thunderbird (2002–2005) and LS (1999–2006). It is made to match the original equipment specifications for a direct and precise fit. The kit includes four small and two large front lower control arm bushings along with two insert sleeves, suitable for both the driver and passenger sides. The components are crafted using a combination of aluminum, rubber, steel, and plastic for a durable and factory-accurate build. The bushings are intended to replace worn-out components and restore the suspension system's original geometry. This helps in maintaining the factory handling characteristics of the vehicle. Designed for compatibility with 14mm and 16mm ball joint arms, the product is manufactured in Taiwan to meet industry standards. Installation should be handled by a qualified professional, as it involves pressing out the old bushings and carefully inserting the new ones using appropriate tools. It is recommended to perform a professional wheel alignment after installation to ensure correct suspension performance and tire wear. The surface finish of the components is brand new, and they meet OE/OEM specifications. The kit is not a performance part and does not require drilling during installation. It is sealed and greasable where applicable and follows a direct-fit mounting style. The included sleeves are designed to fit smaller bushes, and the bundle consists of two large and two small aluminum bushings. Backed by a 2-year manufacturer warranty. The product does not fall under universal fitment and is specifically designed for select models only. Compatible OE and interchange part numbers include JLM21535, XR851825, XR851824, and 2W4Z-3079-AA.
