The FAW differential bearing adjusting ring (part numbers 2403071-A4R and 2403071-A4C) is a crucial drivetrain component built for FAW commercial heavy-duty trucks. Manufactured under original OEM specifications, this threaded collar lets mechanics set the exact bearing preload and gear lash inside the differential housing, preventing premature wear and gear noise during long-haul trips.
⚙️ Reliable Axle Adjustment for Heavy-Duty Diesels
Maintaining correct bearing preload and ring-and-pinion gear backlash is essential to avoiding axle overheating and gear failure. The differential adjusting ring delivers dependable performance:
- Precise Clearance Control: Threaded design allows fine adjustments to achieve perfect gear mesh and bearing tension.
- High-Strength Steel Build: Rugged metal construction resists stripping, cracking, and deformation under heavy axle loads.
- Direct OEM Fit: Engineered to match factory differential carrier housing threads and bearing caps for a precise, secure installation.
