The FAW differential spider (part numbers 2403061-A6A and 2403061-A6C) is a vital internal drivetrain component built for FAW commercial heavy-duty trucks. Manufactured under original OEM specifications, this sturdy cross gear carrier links the pinion gears inside the differential housing, ensuring smooth power distribution and safe cornering during long-haul trips.
⚙️ Reliable Differential Support for Heavy-Duty Diesels
Maintaining sturdy gear alignment and reliable load distribution is vital to preventing axle failure under heavy towing. The differential spider delivers dependable performance:
- High-Strength Forged Steel: Rugged metal construction resists cracking, wear, and structural fatigue under heavy acceleration and payload stress.
- Precision Journal Alignment: Accurately ground bearing surfaces fit tightly with pinion gears to reduce backlash and internal friction.
- Compatibilidad directa con el fabricante original: Engineered to match factory differential carrier specifications for a precise, hassle-free rebuild or repair.

🔧 When Should the Differential Spider Be Replaced?
The spider should be inspected when servicing the differential or rear axle. Replacement may be required if the component has visible wear, damage, or excessive clearance.
| Condición | Recommended Check |
|---|---|
| Visible wear | Inspect the spider and gear contact surfaces |
| Excessive gear play | Check the spider, gears, and washers |
| Abnormal differential noise | Inspect the complete differential gear set |
| Damaged internal parts | Check the spider and related components |
| Rear axle overhaul | Inspect all differential components |
For best results, inspect the related planetary gears, half shaft gears, and washers at the same time.
