ABS 910140 Nut Stub Axle

ABS 910140 Nut Stub Axle

The ABS 910140 Nut Stub Axle is a precision‑engineered component designed to secure the drive shaft within the vehicle’s front or rear axle assembly. It serves as the critical interface between the drive shaft, the hub, and the wheel assembly, ensuring that torque transmission remains stable under high load conditions while maintaining alignment integrity.

Key Functional Characteristics

• High‑strength alloy construction – The nut is forged from a hardened steel alloy that resists fatigue and corrosion, providing long‑term durability even in demanding operating environments.
• Threaded design (M22x1.5) – A metric thread profile with a pitch of 1.5 mm allows for secure engagement with the corresponding stub axle shaft or hub flange.
• Locking mechanism compatibility – The nut is engineered to accept standard lock washers, nylon insert locks, or other anti‑loose devices commonly used in automotive assemblies.
• Load capacity – Rated for high torque loads typical of passenger cars and light commercial vehicles, ensuring reliable performance during acceleration, braking, and cornering.
• Corrosion resistance – Surface treatment (e.g., zinc coating or anodizing) protects against rust and extends service life in varied climates.

Applications and Vehicle Compatibility

The ABS 910140 Nut Stub Axle is a universal part that fits a wide range of vehicle models across multiple manufacturers. Its compatibility spans:

• Front axle assemblies – Used on the left and right sides of front‑wheel drive vehicles.
• Rear axle assemblies – Suitable for rear‑wheel drive or all‑wheel drive configurations.
• Manufacturer coverage – Designed to match original equipment specifications for Alfa Romeo, Honda, Hyundai, Mazda, MG, Mitsubishi, Nissan, Subaru, Toyota, and many others.
• Model range – Includes popular models such as the i30 (FD), i30 CW (FD), PASEO Coupe (EL54), MX‑5 I (NA), MX‑5 II (NB), DEMIO (DW), MICRA I (K10), MICRA II (K11), and numerous other sedans, hatchbacks, coupes, and sport cars.

Installation Guidelines

1. Preparation – Clean the stub axle shaft or hub flange to remove grease, dirt, and old thread locker residue. Inspect for damage or wear.
2. Thread Locker Application – Apply a suitable thread‑locking compound (e.g., Loctite 242) to the nut’s internal threads if required by the vehicle manufacturer’s specifications.
3. Nut Seating – Align the ABS 910140 Nut Stub Axle with the stub axle shaft and tighten manually until fully seated.
4. Tightening Sequence – Use a torque wrench to apply the manufacturer‑specified torque value, typically ranging from 80 Nm to 120 Nm depending on vehicle type. Follow a cross‑pattern tightening sequence for dual‑side installations.
5. Locking Device Installation – If a lock washer or nylon insert is used, install it after the nut has reached the target torque and before final tightening.
6. Final Inspection – Verify that the nut is fully seated, threads are free of cross‑threading, and no play exists between the shaft and hub assembly.

Maintenance Tips

• Regularly inspect for signs of loosening or corrosion, especially after extended driving periods or exposure to road salt.
• Reapply thread locker if the nut is removed during maintenance procedures.
• Avoid overtightening, which can strip threads or damage the stub axle shaft.

Material and Finish Details

The nut’s core material is a high‑strength alloy steel (often designated as AISI 4140 or equivalent), chosen for its excellent tensile strength and toughness. The surface finish typically includes:

• Zinc coating – Provides sacrificial protection against oxidation.
• Anodized layer – Enhances wear resistance and reduces friction during assembly.
• Heat treatment – Improves hardness while maintaining ductility for safe handling.

Quality Assurance

The ABS 910140 Nut Stub Axle undergoes rigorous testing to meet or exceed OEM standards. Each batch is inspected for dimensional accuracy, thread integrity, and material composition. The part complies with automotive industry quality certifications such as ISO/TS 16949, ensuring consistent performance across all vehicle platforms.

Conclusion

The ABS 910140 Nut Stub Axle is an essential component for maintaining the structural integrity and reliable torque transfer in a wide array of vehicles. Its robust construction, precise threading, and broad compatibility make it a trusted choice for automotive technicians and vehicle owners alike. By adhering to proper installation procedures and maintenance practices, this nut guarantees long‑term performance and safety on every drive.
