Propeller Shaft Center Bearing Assembly 8-98020880-0 8980208800 For ISUZU NPR 4JH1 Truck

The Propeller Shaft Center Bearing Assembly (OEM Numbers: 8-98020880-0 / 8980208800) is a premium-quality, direct replacement driveline component designed specifically for ISUZU NPR series trucks equipped with 4JH1 diesel engines. This complete center bearing assembly — also known as a driveshaft center support bearing or carrier bearing — is a critical part of the two-piece propeller shaft system. It supports the middle universal joint of the driveshaft, maintaining proper alignment and reducing vibration, noise, and stress on the driveline. The assembly includes the bearing, rubber cushion, and mounting bracket for a complete bolt-on replacement.

Function: The center bearing assembly supports the middle section of the propeller shaft, reducing vibration and ensuring smooth power transfer from the transmission to the rear axle in ISUZU NPR trucks.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• Complete Assembly: Includes bearing, rubber cushion, and mounting bracket — ready for installation.
• High-Quality Bearing: Sealed ball bearing ensures smooth, quiet rotation and long service life.
• Vibration Isolation: Durable rubber cushion absorbs driveline vibration and road shock for a smoother ride.
• Restores Driveline Stability: Eliminates excessive driveshaft movement, clunking noises, and vibration caused by worn center bearings.
• Direct Replacement: Matches OE mounting dimensions, bolt pattern, and bearing position.
• Long Service Life: Engineered for commercial truck duty cycles.
• Essential Driveline Component: Protects universal joints, transmission output bearing, and differential pinion from excessive vibration.
• Cost-Effective Repair: Affordable replacement that prevents costly driveline damage.

This center bearing assembly is specifically designed for ISUZU light-duty trucks. Common applications include:

• ISUZU NPR (Medium-Duty Trucks)
• ISUZU N Series (NP — as applicable)

• ISUZU 4JH1 — 3.0L Inline-4 Diesel
• Application: Light- and medium-duty trucks and commercial vehicles
• Also compatible with various ISUZU models using the same propeller shaft configuration

Professional mechanic or driveline specialist installation recommended:

1. Ensure vehicle is safely raised — Use appropriate jack stands or a lift to access the driveshaft.
2. Mark driveshaft orientation — Before removal, mark the driveshaft and yoke positions to maintain balance during reassembly.
3. Remove the propeller shaft — Unbolt the universal joint straps or flange bolts at the transmission and differential ends; support the shaft.
4. Remove the old center bearing — Unbolt the center bearing bracket from the frame crossmember; separate the bearing from the shaft if necessary.
5. Inspect the driveshaft — Check universal joints and slip yoke for wear or damage.
6. Install the new center bearing — Position the new center bearing assembly on the frame crossmember; align bolt holes.
7. Torque mounting bolts — Tighten to manufacturer torque specifications.
8. Reinstall the driveshaft — Align the match marks made during removal; reconnect universal joints and flanges.
9. Torque driveshaft bolts — Tighten all fasteners to specification.
10. Check for clearance — Ensure the center bearing and driveshaft do not contact the frame or underbody.
11. Road test — Test drive to verify smooth operation and no vibration or noise.
