Additional Notes

  • The INFINITI QX70 S51 front differential holds 0.65 liter across both the 3.7 AWD and 5.0 AWD configurations, a relatively small capacity consistent with a compact front differential unit in an all-wheel-drive transfer arrangement.
  • The rear differential capacity on the 3.7 variants is 1.4 liter, while the 5.0 variants carry a notably larger 1.75 liter rear differential capacity, reflecting a physically larger unit paired with the higher-displacement engine.
  • Both the 3.7 and 5.0 rear differentials share the same check interval of 10,000 miles or 12 months regardless of use condition, meaning the inspection frequency does not change between normal and severe service.
  • Under severe use conditions, a fluid change interval of 20,000 miles or 24 months applies to both the front and rear differentials across all configurations, a schedule that does not appear in the normal use rows.
  • The 5.0 AWD front differential retains the same 0.65 liter capacity and the same check interval as the 3.7 AWD front differential, indicating no capacity or inspection difference between the two engine variants at the front axle.
  • The rear differential specifications for the 3.7 RWD and 3.7 AWD variants are identical at 1.4 liter with the same check and change intervals, showing no capacity distinction between the two drivetrain configurations at the rear axle for the 3.7 engine.
  • The 5.0 engine variants are covered only through 2013-2014, while the 3.7 variants span the full 2013-2017 range, meaning the larger rear differential capacity of 1.75 liter applies only to that earlier two-year window.
