Front intermediate axle shaft kit, 68400416AA, with bearing, collar, snap ring and bushing for Jeep Wrangler JL and Gladiator JT Rubicon Dana M210 axles.
Gear oil weeping out of the long side of the front axle tube, a growl or rumble from the front that does not change when you steer, or a chewed spline found while swapping axle shafts on a Rubicon are the usual reasons Wrangler JL and Gladiator JT owners look up Mopar 68400416AA. This is the front intermediate axle shaft kit for the Dana 44 M210 front axle, the Rock-Trac axle under the JL and JT Rubicon. It is a complete kit: the intermediate shaft plus its bearing, collar, snap ring and bushing, so the shaft goes in with fresh support hardware instead of reused parts.
The JL front differential is offset to one side of the housing, which leaves one long tube. Instead of a single long inner axle on that side, the M210 uses an intermediate shaft: its inner end splines into the differential side gear, it runs out through the tube on its own support bearing, and the outer axle shaft and U-joint couple to it at the end of the tube. The collar and snap ring lock the bearing in position and the bushing keeps the shaft centered. When the bearing wears or the snap ring lets the shaft walk, the shaft rubs and wobbles in the tube, and oil from the differential finds its way past.
Drain the front differential and look at the oil and the magnet. Pull the outer axle shaft on the long side and check the end of the intermediate shaft: rough or notchy rotation, radial play, or worn splines on either shaft point to this kit. Remember that ring and pinion or carrier bearing noise sounds similar, and that a leak at the knuckle can also be the outer seal. Our Dana 44 problems guide walks through telling them apart. If your front locker is also acting up, read the JL locker actuator guide while the axle is open, and the replacement JL axle locker actuator is listed separately.
Listed fitment for this kit: Jeep Wrangler JL Rubicon 4WD 2018-2025, Wrangler Unlimited JL Rubicon 4WD 2018-2022 and Gladiator JT Rubicon 4WD 2020-2025, all with the Dana 44 M210 front axle. Mopar's own catalog applies 68400416AA to more JL and JT trims than the Rubicon, and Mopar also lists a second intermediate shaft number, 68400417AA, for many of the same models, so the trim badge alone does not settle it. Check the axle tag, compare the old shaft's length and spline count, or send us your year and VIN before ordering. A JL with the Dana 30 M186 front uses different parts; our Dana 30 vs Dana 44 guide explains how to tell the axles apart. More M210 parts are in the hard parts collection.
If the ring and pinion is worn or you are regearing for bigger tires, do it now while the axle is drained: the JL and JT Dana 44 front master install kit covers the bearings and seals, and the Eaton ELocker for the M210/M220 is the upgrade if the factory locker has failed.

The intermediate shaft plus the bearing, collar, snap ring and bushing that support and retain it.
Yes. The listed fitment includes the 2020-2025 Gladiator JT Rubicon 4WD with the Dana 44 M210 front.
Plan on two to three hours with basic hand tools, a snap ring plier and a way to support the Jeep. You have to pull the outer axle shaft through the knuckle first.
Inspect the outer shaft splines and U-joint while it is out. If the splines are worn or the joint is loose, replace it now. Any leaking seal on that side should be replaced too.
