Differential Cage Assembly 8-97319396-1 8973193961 For ISUZU NKR NPR Truck

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• High-Strength Construction: Durable cast iron or steel withstands high torque loads and continuous rotation.
• Surface-Hardened Gear Seat Surfaces: Induction-hardened surfaces provide exceptional wear resistance and long service life.
• Precision-Machined Journals: Exact tolerances ensure proper bearing support and correct gear backlash adjustment.
• Restores Differential Performance: Eliminates differential noise, excessive backlash, and power loss caused by a worn or damaged cage.
• Direct Replacement: Matches OE assembly dimensions and mounting configuration for simple installation.
• Long Service Life: Engineered for light- and medium-duty commercial truck applications.
• Essential Driveline Component: Critical for proper differential function and reliable power transfer to the rear wheels.
• Cost-Effective Repair: Affordable replacement that prevents costly damage to gears and bearings.
• Wide Compatibility: Suitable for multiple ISUZU models using the same differential configuration.

This differential cage assembly is specifically designed for ISUZU light- and medium-duty trucks and commercial vehicles. Common applications include:

• ISUZU NKR (Light-Duty Trucks)
• ISUZU NPR (Medium-Duty Trucks)
• ISUZU N Series (MK, NK, NP - as applicable)
• Engine Applications: ISUZU Diesel Engines (verify engine model with VIN)
• Also compatible with various ISUZU models using the same rear axle differential configuration

Professional mechanic or driveline specialist installation is strongly recommended:

1. Ensure vehicle is safely raised - Use appropriate jack stands or a lift to support the rear axle.
2. Drain differential oil - Drain the lubricant into a suitable container.
3. Remove the propeller shaft - Disconnect the propeller shaft from the differential companion flange.
4. Remove the axle shafts - Remove the rear wheels, brake drums, and axle shafts to access the differential.
5. Remove the differential carrier - Unbolt and remove the differential carrier assembly from the axle housing.
6. Disassemble the differential - Remove the bearing caps, ring gear, and differential case assembly. Note: Mark the bearing caps and shims for reassembly.
7. Remove the old differential cage - Separate the cage assembly from the ring gear and internal gears; note the orientation of all components.
8. Clean and inspect - Clean all components; inspect the ring gear, pinion gear, side gears, and bearings for wear or damage; replace if necessary.
9. Install the new differential cage - Position the new assembly with the internal gears and ring gear; align all components.
10. Adjust backlash and contact pattern - Use shims to set proper backlash and verify gear contact pattern using marking compound.
11. Reassemble the differential - Install the differential carrier into the axle housing; torque mounting bolts to specification.
12. Reinstall axle shafts - Install the axle shafts, brake components, and wheels.
13. Reconnect the propeller shaft - Align match marks made during removal; reconnect universal joints and flanges.
14. Refill differential oil - Fill with the correct grade and quantity of differential lubricant.
15. Road test - Test drive to verify smooth operation, no abnormal noise, and proper power delivery.
16. Re-check oil level - After the initial drive, check for leaks and top up differential oil if necessary.
