{"title":"Coil \u0026 Strut Assembly","description":"\n\u003cp\u003eA coil-and-strut assembly combines a suspension spring with a damper and, on a MacPherson-type layout, a structural strut that helps locate the wheel. A complete unit may also include the top mount, bearing, spring seats, isolators, dust boot and bump stop. “Loaded” or “quick-fit” assemblies reduce spring transfer work, but their spring rate, installed height, damping curve and mount geometry must still match the vehicle exactly.\u003c\/p\u003e\n\u003cp\u003eMatch by VIN, production date, front or rear position, left\/right side, axle-weight code, body and drivetrain, suspension package and electronic-damping equipment. Sport, heavy-duty, raised, self-levelling and adaptive systems can look similar. Compare lower bracket, brake-hose and sensor tabs, top-mount stud pattern, spring colour codes and damper connector. Confirm whether fasteners and any ride-height or acceleration sensor brackets are included.\u003c\/p\u003e\n\u003cp\u003eNoise, bounce or uneven height does not prove the complete assembly is faulty. Inspect the tyre, wheel bearing, anti-roll link, arm bushes, ball joint, spring ends, top bearing, damper shaft, knuckle and body tower. A broken spring can hide in its seat; oil mist differs from an active damper leak. Compare heights on level ground with normalised load, then assess damping and play using the vehicle method.\u003c\/p\u003e\n\u003cp\u003eA compressed road spring stores enough energy to cause fatal injury. If transferring parts, use a compressor rated for the spring and strut, position every jaw correctly and keep clear of the potential release path. Never use improvised clamps, general ratchet straps or a damaged compressor. Support the vehicle at approved points and never undo the centre piston nut until the spring is fully and demonstrably restrained.\u003c\/p\u003e\n\u003cp\u003eInstall the mount, seats, spring ends and isolators in their indexed positions, use new one-time nuts and bolts, and counter-hold the shaft as instructed. Tighten lower and top fixings in sequence, reconnect hoses and wiring without twist, then settle the vehicle. Complete wheel alignment and any adaptive-damper or ride-height calibration. Coil-and-strut assemblies listed below should restore matched ride height, travel, damping and steering geometry, preferably in axle-balanced condition.\u003c\/p\u003e","products":[],"url":"https:\/\/automotopart.co.uk\/collections\/p_coil-strut-assembly.oembed?page=288","provider":"AutoMotoPart","version":"1.0","type":"link"}
