Product Introduction 2902930LE010 Leaf Spring Bushing is a key vibration isolation component for HFCN721 light truck leaf spring suspension assembly. Installed between leaf spring and axle bracket, it cushions impact force during driving and allows slight rotational movement of the leaf spring while reducing metal-to-metal friction. This aftermarket replacement bushing resolves abnormal clunking noise, loose suspension positioning and poor shock absorption triggered by cracked rubber, hardened material and worn inner sleeves of original bushings, stabilizing chassis structure and extending service life of suspension parts for urban logistics light commercial vehicles.

Product Advantages High-performance rubber compound has excellent wear resistance and shock absorbing ability under heavy load and repeated compression. Reinforced metal inner sleeve provides strong structural support and prevents deformation. The integrated design reduces installation gaps and suppresses abnormal noise. Each bushing undergoes compression and aging testing before shipment, effectively buffering road shock and lowering chassis maintenance cost.

Applicable Models Fit for JAC HFCN721 light truck series, matches original leaf spring suspension assembly for short-distance cargo delivery and urban logistics vehicles.

FAQ

Q1: What noise indicates failed leaf spring bushing?
A1: Clunking or knocking sound from chassis when passing bumps, especially during turning or braking.
Q2: What accelerates leaf spring bushing rubber aging?
A2: Mud and water intrusion, long-term heavy loading and large temperature changes will speed up aging.
Q3: Should I replace all related bushings together during maintenance?
A3: Better to inspect all suspension bushings and replace worn ones at the same time.
Q4: Can damaged bushing cause leaf spring bolt breakage?
A4: Yes, excessive movement creates extra stress and may lead to bolt fatigue fracture.
