Product: Rear axle suspension bushing for Vauxhall/Opel Astra J (2009–2015) Purpose: Direct replacement bushing for the rear axle assembly that restores proper suspension alignment, reduces unwanted movement, and maintains handling and ride stability. Key benefits Precise fit and compatibility: Made to match OE number 13313230 exactly for Astra J models 2009–2015. Installs into the original mounting location to maintain factory geometry and predictable handling. Durable construction: Metal core combined with ABS composite material resists wear, deformation, and erosion under regular driving conditions to provide reliable function over time. Ride and safety improvement: Replaces worn or degraded bushings to reduce shimmy, uneven tire wear, and loose rearend feel, restoring stable steering response and consistent vehicle tracking. Easy installation: Designed as a direct replacement for the Astra J rear axle assembly. No modifications required, simplifying maintenance and reducing labor time. What it does Supports the rear axle pivot point to keep alignment and suspension travel within designed limits. Absorbs road forces and helps isolate noise and vibration from the chassis. Maintains correct spacing and preload so other suspension components wear evenly. Compatibility and verification Compatible with Astra J model years 2009, 2010, 2011, 2012, 2013, 2014, 2015. OEM number: 13313230 — please verify this OE number on your vehicle before to ensure exact fit. Material and performance Metal inner structure for strength and load transfer. ABS composite outer material for resistance to abrasion, deformation, and environmental degradation. Engineered to meet original equipment specifications for alignment and stability. Typical use scenarios 1. Suspension : a failed or worn rear axle bushing during axle or control arm replacement to restore factory handling and prevent premature wear of adjacent parts. 2. Postimpact restoration: After a pothole strike or minor collision that affected rear suspension feel, install this bushing to reestablish correct axle positioning and eliminate looseness. 3. Preventive maintenance: aging bushings as part of scheduled suspension maintenance to maintain ride quality and extend the life of tires and suspension components. Notes Confirm OE number 13313230 on your vehicle before ordering to ensure compatibility. Fits specifically for Astra J rear axle assembly (2009–2015); no additional parts or modifications anticipated for standard replacements.
