Product Details
Front Leaf Spring U-Bolt JAC N56
,OEM M14x62x130 Axle Clamp Fastener
,JAC Spare Parts Leaf Spring U-Bolt
The Front Leaf Spring U-Bolt with OEM number 2902021LD010 is a verified direct-fit replacement for JAC N56 light trucks. This U-shaped high-strength fastener is a critical component of the front suspension system, responsible for rigidly clamping the front leaf spring pack to the front axle beam. Proper torque on these U-bolts prevents leaf spring shifting under braking and uneven road conditions, maintaining correct front wheel geometry and steering control.

⚠️ IMPORTANT: Always replace U-bolts in complete sets (both sides of the axle). Do not reuse old nuts. Use a calibrated torque wrench — under-torquing can cause axle misalignment; over-torquing can stretch or break the U-bolt.
- Support the front axle securely on stands.
- Remove the old U-bolt nuts and discard them (do not reuse).
- Remove the old U-bolt and inspect the leaf spring pack for damage.
- Position the new U-bolt over the leaf spring pack and axle beam.
- Install new nuts and hand-tighten evenly.
- Torque nuts in a crisscross pattern to [Insert spec, e.g., 180–220 N·m] in stages.
