What this part is

The Leaf Spring is supplied under the Vidishi Auto brand as a compatible aftermarket replacement. It targets Ford and is referenced by AB39-5B669-FF. A leaf spring carries the vehicle's weight and locates and holds the axle in place; failure shows up as ride-height, handling and noise changes before visible damage. Common failure signs are rear sag or low stance, cracked or broken leaves (often at the centre bolt or spring eye), uneven ride height, excessive bouncing and squeaking or creaking from worn interleaf pads or bushings. Leaf springs should always be replaced in axle pairs; a single new spring creates a weight and stiffness imbalance that causes lean, unpredictable handling and tyre cupping.
