Warn Locking Hubs for Roxor

Installing a classic part on a new vehicle.

Everyone in the off-road industry ought to recognize the name Warn. If not for its extensive line of high-quality winches and recovery products, it should be for one of its first products, the manual locking hub. Warn's own website starts the explanation of its history with this sentence: "Founded in 1948 by Arthur Warn, Warn Industries began producing locking hubs for surplus World War II Jeeps, converting thousands into useful, on-road vehicles."

The Story of These Locking Hubs

The truth is we've installed countless manual locking hubs and manual locking hub conversions to all kinds of 4x4s, often replacing automatic or permanent locking hubs. That's for good reason. Sure, manual locking hubs add a step to getting the traction four-wheel drive affords while on the trail, but they have proven again and again to be more reliable and more efficient than the alternative of solid driver hubs or automatically operating locking hubs. They provide the best of both worlds with the simple turn of a knob, which, like a lever for a transfer case, provides positive engagement of your rig's 4x4 system. Our 2018 Mahindra Roxor came without locking hubs in place on the front axle, but this vehicle uses many parts derived, historically, from Mahindra, which bought the tooling and designs from Willys in 1947. As a result, the front axle uses parts compatible with an already existing Warn Premium Locking Hub kit (PN: 29062, about $250 at various retailers like SummitRacing.com). Part number 29062 works with a slew of 10-spline Dana-based front axles from Jeep and International Harvesters built before 1971.

The Benefits of Locking Hubs

Locking hubs reduce drag while on the road, essentially allowing the front drivetrain that is not engaged at the transfer case to rest idle while driving rather than being turned passively by the front wheels. This helps with steering, fuel economy, and can make an even larger difference if you plan (as we do) to run an automatic locking differential in the front axle.

Installation of Warn's Premium Locking Hubs on Our Roxor (Same for Pre-1971 Jeeps and Some IH 4x4s)

Installation of these locking hubs from Warn is straightforward, but we are happy to run down the steps. Also check out our video on installing the hubs.

1) Remove the Roxor's factory drive flanges. First remove the dust cap from the drive flange. You can use a pair of adjustable pliers, a hammer, and a flat-blade screwdriver.

2) Remove the snap ring from the stub shaft.

3) Remove the six bolts holding the drive flange to the wheel hub, and remove the drive flange.

4) Install the inner locking hub and reinstall the six bolts with the included washers. Lock washers' torque to 27-31 lb-ft.

5) Reinstall the snap ring.

6) Line up the paper gasket and install the outer hub to the locking hub body.

7) Install the six hex head screws.

8) Test the hub.
