Additional Notes

  • The front differential on the Jeep Gladiator, JT (USA / CAN) carries a capacity of 1 liter across both the 3.0 Diesel and 3.6 engine configurations, meaning the fill volume is consistent regardless of engine type.
  • The rear differential without a trailer towing package holds 1.15–1.45 liters on both the 3.0 Diesel and 3.6, a range that reflects manufacturing tolerances in the housing rather than a choice between two fixed fill targets.
  • Rear differentials equipped with the trailer towing package carry a capacity of 1.5 liters on both engine variants, which is higher than the standard rear differential range of 1.15–1.45 liters and reflects a larger differential unit associated with that package.
  • Limited slip rear differentials on both engine variants require 1.5 liters of gear oil plus 0.07 liters of LS-additive. The additive is a friction modifier that conditions the clutch pack inside a limited slip unit and is specified separately from the base fluid volume.
  • On the 3.0 Diesel, front and rear differential service intervals are set at 20,000 miles or 24 months for both normal and severe use conditions, with normal use calling for a fluid check and severe use calling for a fluid change at that same interval.
  • On the 3.6, front and rear differential intervals under normal and severe use extend to 40,000 miles or 48 months, which is double the interval specified for the 3.0 Diesel across equivalent use conditions.
  • The 3.6 includes an initial service condition for the front differential, standard rear differential, and all rear differential variants with or without the trailer towing package, each set at 20,000 miles or 24 months as a check. The 3.0 Diesel specifies an initial service condition only for the rear limited slip differential with the trailer towing package, also as a check at 20,000 miles or 24 months.
  • Under severe use on the 3.6, the rear limited slip differential with the trailer towing package requires a fluid change at 40,000 miles or 48 months, while the initial service condition for the same configuration calls for a check at 20,000 miles or 24 months, establishing a two-stage schedule within that single configuration.
