Additional Notes

Across the Renault Magnum E.Tech (EU) 400, 440, and 480 variants from 2000-2005, the rear differential fluid capacities follow identical patterns, meaning the power output rating has no bearing on the differential fluid volumes specified.
The rear leading differential with hub reductions carries the largest fluid capacity in the lineup at 18 liters, which reflects the added volume required to lubricate both the central differential housing and the integrated hub reduction gearsets at each wheel end.
The rear leading differential without hub reductions holds 16 liters, so the hub reduction assemblies account for an additional 2 liters of fluid capacity when present on a leading axle configuration.
Hypoid rear differentials and rear differentials with hub reductions (non-leading) share the same 15-liter capacity across all three E.Tech variants, indicating a common housing volume between those two distinct axle designs.
Trailing rear differentials, both with and without hub reductions, share a capacity of 14.5 liters across the E.Tech 400, 440, and 480, making the trailing axle configuration the lowest-volume differential application in the specification set.
The fact that trailing axle hub reductions do not add fluid volume over the standard trailing differential, unlike the leading axle equivalent, points to a structural difference in how hub reductions are integrated between leading and trailing axle designs.
All differential fluid capacities in the specification set are given under normal use conditions, which in heavy truck service typically refers to standard on-highway operation as opposed to severe-duty or off-road cycles.
