Additional Notes

  • The Lexus LS 400 (USA) rear differential holds 1.3 liters of fluid across the entire 1990-1994 model year span, a capacity consistent with the compact rear differential units commonly found in rear-wheel-drive luxury sedans of the era.
  • Under normal use conditions, the 1990-1994 LS 400 rear differential calls for a fluid check at 15,000 miles or 24 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions, the same 15,000-mile or 24-month interval applies, but the required service shifts from a check to a full fluid change, reflecting the greater fluid degradation associated with demanding driving conditions.
  • The 1.3-liter capacity figure remains unchanged across all four model years covered in the specifications, indicating no revision to the rear differential assembly or its fluid volume requirement between the 1990 and 1994 model years.
  • The dual-condition interval structure, where normal use triggers an inspection and severe use triggers a replacement at the same mileage and time threshold, means the service interval itself does not differ between the two conditions, only the nature of the required action does.
