Front Axle Hub 8-97035160-0 8970351600 For ISUZU NMR85 NLR85 NPR81L NPR71L — OEM Verified Direct Fit, Disc Brake Compatible, Cross-Reference 8970813220

The hub is designed for disc brake applications on the NMR85 platform from 2015 onward, equipped with the 4JJ1 Euro 5 / Euro 5+ diesel engine. It is a direct-fit replacement for the original hub assembly and is cross-referenced against 8970813220 in independent parts catalogs. An additional cross-reference to 8970171931 appears in some supplier listings, though this should be verified against the original unit before ordering.

• ✓Cross-Reference Verified: Explicitly cross-referenced to 8970813220 for NMR85 disc-brake applications from 2015 onward, per independent parts catalog data. A secondary cross-reference to 8970171931 is listed by at least one supplier and should be treated as a lead for verification, not an automatic interchange.
• ✓Platform-Specific Fitment Verified: Confirmed for ISUZU NMR85 (E5, 4JJ1) and NLR/NMR chassis families via Russian-market ISUZU parts catalogs and NovaBus listings explicitly stating "HUB; FRT AXLE NLR/NMR".
• ✓NPR Variant Fitment Verified: NPR81L (4HL1, model year 2003) and NPR71L (4HG1, model year 2000) are listed as direct applications of 8970351600, providing concrete NPR sub-model anchors rather than a blanket "NPR" claim.
• ✓Brake Configuration Verified: The NMR85 application is specifically for disc brake front axles from 2015+; drum-brake or earlier configurations may use a different hub.
• ⚠Weight / Bolt Count / Material: Not independently confirmed across accessible public sources for this specific part number. Do not assume specifications from adjacent ISUZU hub part numbers (e.g., 8-97017206-0). Confirm via supplier data sheet or physical sample before quoting to end-users.

• Wheel bearing noise (humming/growling): A worn hub bearing race or damaged bearing surface causes continuous noise that changes with vehicle speed — often the first sign of hub degradation.
• Vibration through steering wheel or chassis: Excessive hub runout or bearing play transmits vibration felt during driving, especially at highway speeds.
• Wheel wobble or looseness: Visible movement at the wheel when the vehicle is raised — indicates bearing failure or hub wear beyond specification.
• Brake pulsation: Hub runout can cause the brake rotor to wobble, producing pedal pulsation during braking — particularly relevant on disc-brake NMR85 applications.
• ABS fault codes (where equipped): A damaged or improperly seated hub can affect wheel-speed sensor signal integrity on ABS-equipped vehicles.

• This is not a "universal NPR" hub. The NPR line spans multiple generations and chassis codes. The confirmed NPR fitments are NPR81L and NPR71L specifically. Other NPR chassis (e.g., NPR75, NPR-HD with 4HK1, NQR variants) may use different front hub assemblies.
• Do not interchange with 8-97017206-0. That hub is for a different ISUZU platform configuration (NQR66/NPR/4HF1/4HG1 with a 5-bolt flange). Platform and bolt-pattern differences make them non-interchangeable.
• Brake type matters: The confirmed NMR85 application is disc brake. If your vehicle is drum-brake equipped, verify the correct hub part number before ordering.
• Provide the full chassis number (e.g., NPR81L, NMR85) and original hub markings at inquiry to eliminate platform-mismatch risk.

Each unit receives dimensional and visual inspection before packaging. Because publicly available specification data for this exact part number is limited, a physical sample or supplier technical sheet should be obtained before committing to bulk orders.

1. 1Safety first: Park on level ground, engage parking brake, and chock rear wheels. Loosen front wheel lug nuts before raising the vehicle.
2. 2Raise and support: Lift the front axle and secure with jack stands. Remove the wheel.
3. 3Remove brake caliper and rotor (disc brake applications): Support the caliper to avoid stressing the brake hose. Remove the rotor retaining screws and slide the rotor off.
4. 4Remove hub nut and bearing: Remove the axle nut and withdraw the outer bearing. Note the orientation of the washer and adjusting nut.
5. 5Remove hub assembly: Slide the hub off the spindle. Inspect the spindle for wear, scoring, or damage.
6. 6Compare new and original hubs: Before installation, verify the bolt pattern, bearing bore dimensions, and overall height match the original unit. This is critical given the limited public specification data for this part number.
7. 7Install new hub: Slide the new hub onto the spindle. Install bearings with appropriate grease.
8. 8Set bearing preload: Adjust the hub nut to the workshop manual specification. Over-tightening causes bearing overheating; under-tightening causes wheel wobble.
9. 9Reinstall brake rotor and caliper: Refit the rotor and caliper. Reinstall the wheel and torque lug nuts to specification.
10. 10Road test: Lower the vehicle and test drive, listening for abnormal bearing noise and checking for vibration and brake function.

• Inspect front wheel bearings at every 40,000–50,000 km or during brake service.
• Repack or replace wheel bearings every 80,000–100,000 km or if noise/wobble develops.
• Replace hub seal whenever the hub is removed — seals are single-use.
• Check hub runout if brake pulsation or vibration is reported.

• Standard packing: Neutral carton with protective coating; wooden pallet for bulk export orders.
• Package contents: 1 × Front Axle Hub (bearings, seals, and mounting hardware not included unless explicitly stated).
• Minimum order: Sample accepted for verification — strongly recommended given the limited public specification data.
• Suitable for: ISUZU NMR/NLR fleet maintenance, NPR81L/NPR71L service, spare parts distributors, and export wholesalers.
• Related parts available: Front wheel bearings (inner/outer), hub seals, axle nuts, brake rotors, and wheel studs/lug nuts for the confirmed platforms.
