Additional Notes

  • The Cadillac DeVille (USA / CAN) rear differential capacity for the 1957-1958 model years is specified at 2.35 liters, which is slightly lower than the 2.4 liters listed for all subsequent model year ranges in the same system.
  • Starting with the 1959-1960 model years, the rear differential capacity settles at 2.4 liters and remains consistent across all later configurations through 1974, covering both standard and limited slip differential variants.
  • The 1957-1958 rear differential check interval is set at 3,000 km under normal use conditions, which is notably shorter than the 6,000 km interval introduced for the 1959-1960 and 1961-1963 model years.
  • From the 1968-1969 model years onward, the check interval shifts from a distance-based measurement to a time-based one, specified at every 6 months under normal use conditions, a format that continues through the 1970-1974 range.
  • The 1968-1969 and 1970-1974 model year ranges each carry two separate rear differential entries: one for the standard rear differential and one for the limited slip rear differential. Both share the same 2.4-liter capacity and 6-month check interval under normal use conditions.
  • The limited slip differential designation appears only in the 1968-1969 and 1970-1974 specifications. A limited slip differential uses a friction-based or gear-based mechanism to distribute torque between rear wheels, and fluid compatibility is typically more specific than for open differentials, though the capacity listed here matches the standard unit at 2.4 liters.
  • The 1959-1963 model years share identical rear differential specifications, with a 2.4-liter capacity and a 6,000 km check interval under normal use conditions, despite spanning two separate row entries covering 1959-1960 and 1961-1963.
