Additional Notes

  • The rear limited slip differential on the Ford F-150 11th Gen. accepts between 2.6 and 3.3 liters of fluid across all listed engine configurations, including the 4.2 V6, 4.6 V8, and 5.4 V8. A capacity range rather than a fixed value typically reflects variation between different axle ratio or housing options fitted to the same model generation.
  • The front differential on 4x4 variants of the 4.6 V8 and 5.4 V8 holds a fixed 2 liters, a notably smaller capacity than the rear unit. Front differentials in solid-axle or independent front suspension setups are generally smaller assemblies, which accounts for the reduced fill volume.
  • The front differential on all listed 4x4 configurations carries a 150,000-mile normal-use change interval, which is 50,000 miles longer than the rear limited slip differential under the same normal-use condition. Only a normal-use interval is listed for the front differential; no severe-use interval appears in the specifications.
  • Rear limited slip differential fluid on the F-150 4.2 V6 (2005-2008) is specified at a 100,000-mile interval under normal use and 50,000 miles under severe use. The severe-use interval represents exactly half the normal-use figure, a common pattern for drivetrain fluids subjected to elevated heat, towing loads, or frequent stop-and-go operation.
  • The same rear limited slip differential capacity range of 2.6-3.3 liters and the same dual-interval structure of 100,000 miles normal and 50,000 miles severe apply identically to the 4.6 V8 and 5.4 V8 configurations, including their 4x4 variants and the 5.4 V8 4x4 Flex Fuel variant.
  • The 4.2 V6 specifications begin in 2005, while all V8 configurations are listed from 2004, meaning the V8 entries cover one additional model year within the 2004-2008 generation span.
  • The 5.4 V8 4x4 Flex Fuel variant shares identical differential capacities and service intervals with the standard 5.4 V8 4x4, indicating that the flex fuel capability does not alter differential fluid specifications for either the front or rear axle.
