Locking hubs for the Ford F-250 don’t come in one universal fit. The F-250 ran three distinct front axle generations across its production history, and the hubs that bolt onto a 1999 Super Duty are not the same as what fits a 2005 or a 1985. Get the wrong set and you’ll find out at install time — usually when the spline count doesn’t match the stub shaft. This guide covers fitment by generation, the two part numbers that cover most of the modern Super Duty range, and the one spec detail that trips up most buyers.
Scope: 4×4-equipped Ford F-250 trucks with front locking hubs. Does not cover F-150, F-350, or 2WD configurations.
Which locking hubs fit a Ford F-250?
The correct locking hub for a Ford F-250 depends on the model year and front axle designation — not the cab style, bed length, or engine. The F-250 used three different front axle setups across its production run, and each generation requires a different hub.
| Year Range | Front Axle | Spline Count | Hub Options | Notes |
| 1977–1979 | Dana 44 SFA (open knuckle) | 19-spline (verify) | Torque King Dana 44 hubs, Warn | Solid front axle; confirm spline count against your specific axle |
| 1980–1997 | Dana 50 IFS/TTB | 27-spline (verify) | Mile Marker 449S/S, Warn | Twin Traction Beam IFS; Torque King stocks Dana 50 IFS hub parts |
| 1999–2004 | Dana 60 SFA | 30-spline (stock) | Mile Marker 449S/S, Warn 38826 | Super Duty first gen; 35-spline hubs require stub shaft upgrade |
| 2005–2020 | Dana 60 SFA | 35-spline | Mile Marker 549, Warn 95060/95070 | Super Duty second gen; 549 and Warn 95060 are cross-compatible |
For the 1999–2004 Super Duty: Both manual and automatic OEM hubs use the Dana 60 solid front axle. The stock stub shaft is 30-spline. The Mile Marker 449S/S fits 1999–2004 F-250, F-350, F-450, and F-550 in 4×4 configuration, and replaces both OEM manual and automatic hubs. Warn 38826 is the corresponding Warn fitment for this generation.
For the 2005–2020 Super Duty: The Mile Marker 549 fits 2005–2020 F-250, F-350, F-450, and F-550 4WD on the 35-spline Dana 60. The Mile Marker 549 is cross-compatible with Warn part numbers 95060 and 95070, so either brand’s hub will bolt up to the same axle stub.
For pre-1999 F-250: Hub fitment on the 1977–1997 range depends on which axle your specific truck has. The 1977–1979 trucks used a Dana 44 open knuckle solid front axle. The 1980–1997 trucks used the Dana 50 IFS, also called the Twin Traction Beam. Torque King Industries catalogs hub parts by axle designation for both generations — confirm your axle designation before ordering.
What do you need for a Ford F-250 locking hub swap?
A Ford F-250 manual locking hub swap on the 1999–2004 or 2005–2020 Super Duty requires the hub set, standard hand tools, and wheel bearing grease. On these generations, the OEM auto-locking hubs pull out and the new manual hubs drop in without drilling or cutting.
Parts:
- Manual locking hub set (2 hubs) — Mile Marker 449S/S for 1999–2004, Mile Marker 549 for 2005–2020
- High-temperature wheel bearing grease, NLGI #2 (required for hub needle bearings and O-rings)
- New hub cap retaining snap ring or circlip if not included in kit (check kit contents)
Tools:
- Floor jack and jack stands
- Lug wrench
- Snap ring pliers
- Flathead screwdriver
- Torque wrench
- Shop rags
No conversion kit is required on most Super Duty applications — the manual hub seats directly where the OEM auto hub was. On some 1999–2004 trucks, users have reported that the OEM automatic hubs pop out by hand once the snap ring is removed, with the new manual hubs seating without any additional hardware.
On pre-1999 F-250 trucks with the Dana 50 TTB, confirm whether a conversion kit is needed — some TTB applications require an additional locking ring set to adapt the hub to the spindle.
How do you install locking hubs on a Ford F-250?
Installing manual locking hubs on a 1999–2004 or 2005–2020 Ford F-250 Super Duty is a bolt-on job that takes two to three hours if you’re working carefully the first time. Skill level: basic mechanical — if you’ve done brakes, you can do hubs.
Overview of the install sequence:
- Lift the front of the rig and support it on jack stands; remove the front wheels
- Remove the existing hub cap and snap ring from the spindle
- Pull the OEM locking hub assembly off the stub shaft
- Clean the spindle and stub shaft splines; inspect for wear or corrosion
- Pack the new hub’s needle bearings with NLGI #2 wheel bearing grease
- Slide the new manual hub onto the stub shaft, indexing the splines carefully
- Install the snap ring to seat the hub in position
- Install the hub cap and torque to spec per the hub manufacturer’s instructions
- Repeat on the opposite side; reinstall wheels
The most common install mistake on the 1999–2004 trucks: assuming the stock stub shaft is 35-spline when it’s 30-spline. The 449S/S hub is built for 30-spline. If you’ve already purchased 35-spline hubs for a stock 1999–2004 application, the hub will slide onto the shaft but won’t seat or engage correctly. Check the stub shaft spline count before ordering.
A dedicated how-to for the Super Duty hub swap is on the list — for now, the Dynatrac installation documentation for the 1999–2004 F-250 Free-Spin Kit covers the spindle work in detail and applies to standard hub swaps as well.
Does spline count matter when buying F-250 locking hubs?
Yes. Spline count is the single most important spec when buying locking hubs for the Ford F-250 Super Duty, and it’s the detail most buyers get wrong. The 1999–2004 Super Duty came from the factory with 30-spline front stub shafts as standard equipment. The 2005–2020 Super Duty uses 35-spline stub shafts.
A hub designed for 35-spline will not index correctly on a 30-spline shaft — the collar will slide on but the splines won’t mesh, and the hub won’t lock. This is not a torque issue or a reassembly issue. It’s a spec mismatch that requires either the correct hub or a stub shaft upgrade.
If you want to run 35-spline hubs on a 1999–2004 truck, Yukon Gear makes 35-spline stub shaft upgrades for this application that allow the stronger 35-spline hub set to fit. The stub shaft swap adds cost and time to the project but is a legitimate upgrade path if you’re also building the front axle for heavier use.
For a stock 1999–2004 F-250, the Mile Marker 449S/S at 30-spline is the straightforward correct answer. For 2005–2020, the Mile Marker 549 or Warn 95060 at 35-spline is the fit.
What is Ron’s pick for Ford F-250 locking hubs?
Ron’s pick for the 1999–2004 Ford F-250 Super Duty is the Mile Marker 449S/S. It’s a direct-fit manual hub replacement for the Dana 60 30-spline stub shaft, builds on Mile Marker’s stainless steel construction, and replaces factory auto hubs that have logged six-figure miles without requiring a conversion kit. Several Ford Truck Enthusiasts forum users report the same experience: OEM auto hubs out, Mile Marker 449S/S in, no drama.
Ron’s pick for the 2005–2020 Super Duty is the Mile Marker 549 or Warn 95060 — both fit the 35-spline Dana 60 and are cross-compatible, so whichever is in stock at a better price is the right call. Warn carries a strong warranty reputation and is easier to deal with on returns if you run into a defective unit.
On the pre-1999 trucks, hub selection gets more specific to the individual axle. If you’re running a 1980–1997 F-250 with the Dana 50 TTB, Torque King Industries is the most thorough source for hub parts specific to that axle. Their catalog breaks down by axle designation, not just vehicle year, which matters on trucks that may have had axle swaps over the decades.
Check the current price on Mile Marker 449S/S hubs for 1999–2004, and Mile Marker 549 hubs for 2005–2020.
Where do locking hubs fit in the F-250 four-wheel drive system?
Locking hubs sit at the wheel end of the F-250’s front drivetrain chain: transfer case, front driveshaft, Dana 60 differential, front axle shafts, locking hubs, wheels. When the hubs are unlocked in 2WD, the front axle shafts, differential carrier, and driveshaft all stop spinning. That’s a significant rotating mass on a Dana 60 solid front axle, and eliminating that drag in 2WD is the main reason Ford F-250 owners convert from factory auto hubs to manual.
