SsangYong Rexton, Y400/Y450
Differential fluid capacity & service interval
SsangYong Rexton Y400/Y450 differential fluid capacity ranges from 1,4 to 2 liters. Service intervals require a change every 30000 km. The data covers 6 configurations.

Additional Notes
- The rear differential on the SsangYong Rexton e-XDi220 carries a capacity range of 1.6 to 2 liters, which reflects a fill tolerance rather than a fixed volume, accounting for variation in drain completeness and housing geometry across service events.
- The front differential on the e-XDi220 4WD configuration holds a fixed 1.4 liters, a notably tighter figure compared to the rear differential's variable range, consistent with the typically smaller housing of a front differential unit.
- All differential fluid change intervals across both the Y400 and Y450 generations are set at 30,000 km under normal use conditions, applying equally to front and rear differentials on 4WD variants.
- The 2WD configuration of the e-XDi220 carries only a rear differential, with a capacity of 1.6 to 2 liters, as the absence of a front differential removes that additional fluid service requirement entirely.
- The 4WD e-XDi220 requires servicing two separate differential assemblies at each 30,000 km interval, with a combined fluid volume of approximately 3 to 3.4 liters when accounting for both the 1.4-liter front unit and the 1.6 to 2-liter rear unit.
- The rear differential capacity specification of 1.6 to 2 liters is consistent across the Y400 (2017-2021) and Y450 (2021- ) generations in both 2WD and 4WD configurations, indicating no change in rear differential housing specification between the two body generations.
