Front Axle Hub 8-97017206-0 8970172060 For ISUZU NQR66 NPR NNR 4HF1 4HG1 — OEM Verified Direct Fit, 5-Bolt Flange, Cast Steel, 11.5kg

The Front Axle Hub with OEM numbers 8-97017206-0 / 8970172060 is a verified direct-fit replacement for ISUZU NQR66, NPR, and NNR series trucks equipped with 4HF1 and 4HG1 diesel engines. This front hub is a critical structural and rotating component of the front axle assembly, responsible for mounting the wheel and brake disc/drum and supporting the vehicle's front-end load through the wheel bearings.

The hub is manufactured from cast steel and features a 5-bolt wheel flange configuration, matching the original ISUZU mold specification for these truck platforms. It is the front axle counterpart to the rear hub assembly and is designed to interface with the front wheel bearings, seals, and brake components.

• Weight Verified: 11.5 kg net weight — confirmed across multiple independent supplier catalogs (okisuzu, isuzureplacementparts).
• Bolt Configuration Verified: 5-bolt flange — confirmed by Accio and Indonesian supplier listings explicitly stating "5 Bolt" / "5 trous de boulons" for the 8970172060 hub.
• Material Verified: Cast steel — confirmed by supplier material specification for the ISUZU front axle hub platform.
• HS Code Verified: 870850000 — confirmed by okisuzu and multiple regional supplier catalogs, ensuring correct customs classification for export.
• Engine & Chassis Coverage Verified: Confirmed compatible with ISUZU NQR66 (4HF1) and broader NPR/NNR (4HF1, 4HG1) applications across multiple language and market listings (English, French, Indonesian, Turkish).
• Mold Verification: Supplier listings state "Meme moule que l'original" (same mold as original) and "Lubang cetakan yang sama dengan Asal" (same mold cavity as original), indicating tooling designed to match OEM geometry.

• Wheel bearing noise (humming/growling): A worn hub surface or damaged bearing race 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 disc to wobble, producing pedal pulsation during braking.
• Grease leakage or seal damage: Worn hub seal surfaces allow differential fluid or grease to escape, leading to bearing starvation and accelerated wear.

• Axle Position: This hub is for the front axle. Confirm whether your vehicle requires left, right, or both — the same hub part number is typically used on both sides for this platform.
• Bolt Pattern Confirmation: This is a 5-bolt flange hub. Verify the wheel bolt pattern (5 holes) on your original hub before ordering.
• Related Hub Reference (Non-Interchangeable): A separate ISUZU front hub reference 8-97107-414-0 / 8971074140 exists for 700P (4HK1) and NPR75/NQR75 applications. Do not assume interchangeability — these are different hub assemblies for different chassis platforms.
• Always verify the OEM number against the vehicle chassis plate or original hub markings before ordering.

Each unit undergoes dimensional and visual inspection before packaging. Manufacturing conforms to supplier-specific quality management standards (ISO/TS16949 where applicable — confirm at inquiry).

1. 1Safety first: Park on level ground, engage the parking brake, and chock the rear wheels. Loosen the 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 disc (if equipped with disc brakes): Support the caliper to avoid stressing the brake hose. Remove the disc retaining screws and slide the disc off.
4. 4Remove hub nut and bearing: Remove the axle nut (or hub 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 — replace if necessary.
6. 6Clean and inspect: Thoroughly clean the spindle and knuckle mating surfaces. Inspect the new hub for any shipping damage and confirm the 5-bolt pattern matches the original.
7. 7Install new hub: Slide the new hub (8-97017206-0) onto the spindle. Install the inner and outer bearings with appropriate grease.
8. 8Set bearing preload: Adjust the hub nut to the workshop manual specification for bearing preload/end-play. This is critical — over-tightening causes bearing overheating; under-tightening causes wheel wobble.
9. 9Install lock washer and nut: Secure the adjusting nut with a new lock washer or cotter pin as specified.
10. 10Reinstall brake disc and caliper: Refit the brake disc and caliper, and reinstall the wheel. Torque lug nuts to specification.
11. 11Road test: Lower the vehicle and test drive, listening for abnormal bearing noise and checking for vibration.

• Inspect front wheel bearings at every 40,000–50,000 km or during any 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 components.
• Check hub runout if brake pulsation or vibration is reported.

• Standard packing: Neutral box / color box / customer-branded box (supplier options confirmed). Wooden pallet available for bulk export orders.
• Package contents: 1 × Front Axle Hub (bearings, seals, and mounting hardware not included).
• Minimum order: Sample accepted for verification; bulk quantity pricing available.
• Supply capacity: Confirm current availability and lead time at inquiry.
• Suitable for: Truck axle and brake repair workshops, ISUZU N-Series fleet maintenance departments, spare parts distributors, and export wholesalers.
• Related parts available: Front wheel bearings (inner/outer), hub seals, axle nuts, brake discs, and wheel studs/lug nuts for the NQR66/NPR platform.
