| High Light | High-Strength Steel Front Hub Bolt ，Grade 10.9/12.9 Wheel Stud ，Silver Anti-Corrosion Finish Hub Bolt | ||
The ISUZU Front Hub Bolt with Wheel Stud, OEM numbers 8-94383335-0 / 8943833350, is a precision-engineered replacement designed for ISUZU NPR94 and 700P series light/medium-duty trucks, compatible with 4HK1 diesel engines. This critical safety component securely fixes the wheel to the hub, ensuring the wheel does not loosen during vehicle operation.
The front hub bolt with wheel stud is a critical connection component between the wheel and the hub. The wheel stud is press-fitted into the hub flange, and the wheel is mounted onto the studs through rim bolt holes. Lug nuts are tightened from the outside to securely fasten the wheel to the hub. During vehicle operation, this assembly withstands complex alternating loads including vehicle weight, payload, acceleration/braking forces, and cornering lateral forces.
| Symptom | Probable Cause |
|---|---|
| Wheel wobble or vibration during driving; steering wheel shaking | Loose or broken hub bolt; insecure wheel attachment |
| Thread wear, stripping, or rust found when removing wheels | Long-term use causing thread damage; insufficient clamping force |
| Visible bending or fracture of hub bolt | Overload or material fatigue |
| Periodic "clunking" noise from wheels during driving | Loose hub bolt; relative movement between wheel and hub |
| Cracks or visible deformation found during visual inspection | Bolt reached fatigue life or suffered impact damage |
| Material Grade | High-Strength Steel — compliant with ISO/TS16949 automotive quality management system |
| Strength Grade | Meets Grade 10.9 or 12.9 high-strength bolt standards |
