Additional Notes

  • The Bristol 401 rear differential holds between 1.7 and 2.25 liters of fluid, a range that reflects acceptable fill variation rather than a fixed target volume.
  • A check interval of 3,000 miles is specified under normal use conditions, placing routine inspection well ahead of the full drain-and-fill cycle.
  • The change interval under normal use is set at 6,000 miles, which is double the check interval, indicating a two-stage maintenance rhythm where monitoring precedes replacement.
