Leaf Spring Rear Bushing 1513510100 1876101640 1-51351010-0 1-87610164-0 For

The Leaf Spring Rear Bushing (OEM Numbers: 1513510100 / 1876101640 / 1-51351010-0 / 1-87610164-0) is a premium-quality, direct replacement suspension component designed specifically for ISUZU FVR34 series heavy-duty trucks equipped with 6HK1 diesel engines.

This rear leaf spring bushing - also known as a spring eye bushing, shackle bushing, or suspension bushing - is installed in the rear eye of the leaf spring or the spring shackle. Its primary function is to isolate road vibration, absorb shock, and allow controlled articulation between the leaf spring and the frame bracket. It maintains proper spring alignment, reduces noise, and extends the life of the suspension system by preventing metal-to-metal contact.

• High-Quality Rubber Compound: Oil-resistant, ozone-resistant, and fatigue-resistant for long service life
• Excellent Vibration Damping: Effectively isolates road shock and vibration from the chassis
• Steel Sleeve Construction: Durable steel inner sleeve ensures secure mounting and proper load distribution
• Precision Molded: Exact dimensions guarantee proper press-fit and interference fit
• Restores Suspension Stability: Eliminates clunking, excessive spring movement, and steering wander caused by worn bushings
• Direct Replacement: Matches OE bushing dimensions and mounting configuration for simple installation
• Long Service Life: Engineered for heavy-duty commercial truck duty cycles
• Essential Suspension Component: Critical for maintaining proper spring alignment and vehicle stability
• Cost-Effective Repair: Affordable replacement that prevents costly damage to springs and brackets

Professional mechanic or suspension specialist installation is strongly recommended:

1. Ensure vehicle is safely supported - Use appropriate jack stands or a lift to support the vehicle frame and axle
2. Support the axle - Place a jack under the axle to support its weight during bushing removal
3. Remove the spring pin or bolt - Remove the retaining nut and pin/bolt securing the spring eye or shackle
4. Remove the spring or shackle - If required, disconnect the spring or shackle to access the bushing
5. Remove the old bushing - Use a hydraulic press or bushing driver to press the old bushing out of the spring eye or shackle. Do not use excessive heat
6. Clean the bore - Thoroughly clean the spring eye or shackle bore; remove rust, burrs, and debris
7. Inspect the spring and bracket - Check for cracks, deformation, or damage; replace if necessary
8. Lubricate the new bushing - Apply a small amount of rubber lubricant or soapy water to the outside of the new bushing
9. Install the new bushing - Press the new bushing evenly into the spring eye or shackle using a proper driver or press. Ensure it is fully seated
10. Reinstall the spring or shackle - Reconnect the spring or shackle to the frame bracket; align mounting holes
11. Install the spring pin or bolt - Insert the pin or bolt through the bushing and bracket; install the retaining nut
12. Torque the nut - Tighten to manufacturer torque specifications
13. Check clearance - Ensure the spring and bushing do not contact other components throughout suspension travel
14. Lower the vehicle - Carefully lower the vehicle and remove jack stands
15. Check alignment - A wheel alignment check is recommended after installation
16. Road test - Test drive to verify proper handling, no abnormal noise, and no vibration
