How much fluid does a 2017 F150 differential hold?
On a 2017 Ford F-150, the front differential typically holds about 0.95–1.10 quarts of gear oil, and the rear differential about 2.75–3.25 quarts. Exact figures depend on axle configuration and whether a locking differential is installed. For precise numbers, consult the owner’s manual or the vehicle’s axle tag.
Capacities at a glance
Here is a concise reference for typical capacities on the 2017 F-150. Exact figures vary by axle type and options.
- Front differential: approximately 0.95–1.10 quarts (roughly 0.9–1.0 liters)
- Rear differential (8.8" axle, open or LSD): approximately 2.75–3.25 quarts (roughly 2.6–3.1 liters)
Note: These ranges cover common configurations. For your exact build, verify with the manual or Ford service data.
Front differential capacity
The front differential on the 2017 F-150 usually requires about 0.95–1.10 quarts of gear oil, which is roughly 0.9–1.0 liters. The exact capacity can vary slightly depending on whether the truck has a front locker or other options. Fill until the level reaches the bottom edge of the fill hole, then reinstall the fill plug to the specified torque.
Fill specifications and practical tips
Use the gear oil grade recommended in the owner's manual (commonly a synthetic 75W-90 for the front differential). When replacing fluid, have extra on hand to account for spillage and to reach the proper fill level.
Rear differential capacity
The rear differential for the 2017 F-150 (the typical 8.8" axle) generally holds about 2.75–3.25 quarts of gear oil, equivalent to roughly 2.6–3.1 liters. The exact amount depends on axle ratio and whether a limited-slip differential is installed. Fill until fluid starts to run out of the fill hole, then secure the fill plug.
Notes on limited-slip diffs and oil spec
Some rear differentials with LSD require a friction modifier in the gear oil. Always check the owner's manual for the correct oil specification and whether a modifier is required. A common recommendation is synthetic gear oil in the 75W-140 range for LSD rear differentials, but follow your manual for the exact grade.
How to verify the exact capacity for your truck
Because Ford offered multiple axle configurations for the 2017 F-150, the precise capacity can vary. The most reliable sources are the vehicle’s axle tag, the owner’s manual, or Ford service data for your specific axle ratio and options. When in doubt, consult a dealer or qualified technician to confirm the correct figures and the proper fill procedure.
Summary
For most 2017 F-150s, plan on roughly 1 quart of gear oil for the front differential and about 3 quarts for the rear differential, with variations based on axle type and whether a locking differential is present. Always use the recommended oil grade and follow the manual’s fill procedure to ensure proper lubrication and cooling of the differential gears.
