Additional Notes

  • The Kia Borrego HM rear differential carries a capacity range of 1.4–1.9 liters across both the 3.8 and 4.6 engine configurations, while the 4.6 rear differential has a narrower specified fill window of 1.7–1.9 liters, indicating a tighter tolerance on the acceptable fluid volume for that unit.
  • The front differential on AWD variants, whether paired with the 3.8 or 4.6 engine, holds a capacity of 1.3–1.4 liters, which is a noticeably smaller range than the rear differential and reflects the physically smaller housing typical of a front differential in a rear-biased AWD layout.
  • Under normal use conditions, the rear differential fluid change interval is set at 22,500 miles or 18 months, whichever comes first, and a fluid level check is also specified at 7,500 miles or 6 months as an intermediate service step.
  • Under severe use conditions, the rear differential fluid change interval shortens to 12,000 miles with no mileage-based check interval listed separately, meaning the change itself serves as the primary service action at that reduced interval.
  • The front differential on AWD configurations follows the same interval structure as the rear: a check at 7,500 miles or 6 months under normal use, a fluid change at 22,500 miles or 18 months under normal use, and a change at 12,000 miles under severe use.
  • The capacity range format used throughout these specifications, such as 1.4–1.9 liters, represents the acceptable fill window rather than a single fixed volume, which accounts for manufacturing tolerances and the practical difficulty of achieving a precise fill level when servicing a differential through a fill plug.
  • All twelve specification rows cover the 2008-2009 model years, meaning the differential fluid capacities and service intervals are consistent across both years of the Borrego's production span in the USA market as represented in these specifications.
