Mercedes-Benz G-Class, W463B (EU)

Additional Notes

• Across all four variants of the Mercedes-Benz G-Class W463B (EU) covered here — the G 350 d, G 400 d, G 500, and G 63 AMG — the front differential holds 1.1 liters and the rear differential holds 1.8 liters, with no variation between configurations for either position.
• The rear differential capacity of 1.8 liters is notably larger than the front differential's 1.1 liters, a difference of 0.7 liters that reflects the greater mechanical demands typically placed on a rear axle differential in a rear-biased four-wheel-drive platform.
• All differential fluid service intervals across every listed variant are set at 80,000 km or 48 months, whichever comes first, applying under normal use conditions.
• The 48-month time limit means a fluid change is due after four years regardless of mileage accumulated, which is relevant for low-mileage vehicles that may not reach the 80,000 km threshold within that period.
• The uniform 80,000 km / 48-month interval applies equally to both the front and rear differentials on each variant, meaning both axles are serviced on the same schedule despite holding different fluid volumes.
• The specifications cover the 2019-2024 model years for all four variants, indicating no interval or capacity revisions were introduced across that span for any of the listed configurations.
• The presence of both a diesel lineup (G 350 d, G 400 d) and petrol lineup (G 500, G 63 AMG) sharing identical differential capacities and service intervals suggests the differential specifications are driven by the platform and axle hardware rather than the engine type.
