Additional Notes

  • The Cadillac Fleetwood (USA / CAN) rear differential holds 2.4 liters across all four configurations listed, covering both standard and limited slip variants for 1968-1974.
  • A 2.4-liter differential capacity falls in the range typical of full-size American rear axle assemblies from the era, reflecting the large-bodied platform the Fleetwood rode on throughout 1968-1974.
  • The limited slip differential configurations for both 1968-1969 and 1970-1974 share the same 2.4-liter capacity as the standard rear differential, meaning no additional fluid volume is specified for the limited slip clutch pack.
  • All four rows carry a normal use condition tied to a 6-month check interval, meaning the interval applies specifically to routine operating conditions rather than severe or demanding service cycles.
  • The 6-month check interval is consistent across the 1968-1969 and 1970-1974 model groupings, with no variation in service frequency between the two production periods.
  • The specifications are organized into two distinct model year groupings, 1968-1969 and 1970-1974, each covering both a standard and a limited slip rear differential configuration.
