Driveshaft Universal Joint Cross 8-98020789-0 (8980207890) for ISUZU FSR / NQR / NPR trucks — a direct-fit OEM replacement cross-referenced with 8-97167317-0. Please note a documented dimensional conflict between supplier catalogs; verify your original joint size before ordering.
The Universal Joint Cross with OEM number 8-98020789-0 (8980207890) is listed as a direct-fit replacement for ISUZU FSR and NQR trucks, with cross-reference to 8-97167317-0 (8971673170) per supplier catalog data. This cross shaft connects the driveshaft sections, allowing torque transmission through varying angles as the vehicle moves over uneven roads.
The universal joint consists of a cross-shaped shaft with four needle bearing cups. It transmits rotational power from the transmission to the differential while accommodating changes in driveshaft angle caused by suspension movement and load. Worn joints produce vibration, clunking, or whining noises under acceleration, and can eventually seize or fail.
- ConfirmedApplication: Multiple suppliers list 8-98020789-0 for ISUZU FSR / NQR applications.
- ListedCross-Reference: 8-97167317-0 is listed alongside 8-98020789-0 by one supplier as a related reference for "Propeller Shaft Journal Assembly."
- Supplier ClaimMaterial & Certification: ISO/TS16949 referenced by one supplier.
- CriticalDimensional Conflict: One supplier lists 39 × 121 mm (M-0603). Another lists 35 × 104 mm and associates the number with NPR75 / NQR90. These are materially different sizes — measure your original joint before ordering.
- CautionCross-Reference Validity Questioned: 8-97167317-0 is documented by other suppliers for Isuzu KB250 / KB300 D-Teq (29 × 69 mm), D-MAX, and Trooper — platforms that do not overlap with FSR / NQR. The interchange may be supplier-specific or incorrect. Do not rely on this cross-reference alone.
- Vibration through the floor or steering wheel, especially at certain speeds
- Clunking or metallic knocking noise when accelerating or changing load
- Whining or humming from the driveshaft area
- Visible play or looseness in the joint cups

Universal joint replacement requires driveshaft removal and specialized press tools. Improper installation can cause vibration, premature wear, or driveshaft failure. Professional workshop installation is strongly recommended.
- 1Mark the driveshaft and yoke orientation before removal to maintain balance.
- 2Remove the driveshaft from the vehicle. Support it to avoid damaging the transmission output seal.
- 3Remove the snap rings or retaining clips securing the bearing cups.
- 4Press out the old joint using a suitable press and driver. Clean the yoke bores.
- 5Install the new joint, ensuring bearing cups seat squarely and snap rings engage fully.
- 6Apply specified grease to the joint if grease fittings are present.
- 7Reinstall the driveshaft, aligning marks made during removal. Torque fasteners to OEM specification (confirm in manual).
- 8Test-drive and check for vibration. Rebalance the shaft if vibration persists.
- Inspect universal joints for play and grease leakage every 20,000–30,000 km or during driveline service.
- Lubricate if grease fittings are equipped (per OEM interval).
- Replace if play, vibration, or noise is confirmed.
