Additional Notes

  • The rear differential fluid capacity across all listed Mercedes-Benz GLB-Class X247 configurations is 0.6 liter, a figure consistent with a service fill rather than an overhaul quantity, as overhaul fills typically account for additional volume lost during disassembly.
  • The GLB 250 4MATIC (247.647) carries a rear differential fluid change interval of 46,500 miles or 36 months under normal use conditions, whichever comes first.
  • The GLB 35 AMG 4MATIC (247.651), despite its performance-oriented AMG designation, shares the same 0.6-liter rear differential capacity and the same 46,500-mile or 36-month change interval as the GLB 250 4MATIC.
  • The 36-month time limit paired with the 46,500-mile mileage threshold means the interval is dual-triggered under normal use, so whichever limit is reached first governs the service point regardless of driving frequency.
  • Both the 2019-2023 and the 2023-start entries for the GLB 250 4MATIC (247.647) list identical rear differential specifications, indicating no capacity or interval revision was introduced for the 2023 model year variant carrying a separate chassis designation entry.
