Yukon Gear Replacement Standard Open Carrier Case For Dana 44 / 30 Spline / 3.73 & Down / Bare
If your Dana 44 keeps eating spider gears, a carrier bearing spun on the case, or the ring gear bolts pulled out of the flange, the carrier case itself is finished. Yukon YC D706024-X is a new bare standard open case for 30-spline Dana 44 axles with 3.73 and numerically lower ratios. It suits the stock-geared Dana 44 found front and rear under older Ford, GM, Dodge, Jeep and International 4x4s, where highway gearing such as 3.07, 3.31, 3.54 or 3.73 is common. Bare means the case arrives empty, ready for your spider gears and new carrier bearings.
The case is the rotating housing at the center of the axle. The ring gear bolts to its flange, carrier bearings ride on its journals, and the cross shaft through the case holds two spider gears in mesh with the 30-spline side gears that drive the axle shafts. In an open differential that is all the case does: it carries torque from the ring gear to the cross shaft and lets the wheels turn at different speeds. Dana 44 cases are split by ratio. Gear sets of 3.92 and deeper use a thicker ring gear and a different case, which is why this one is only for 3.73 and down.
Drain the oil, pull the cover and check the cross shaft, roll pin and spider gears. Pull the carrier and inspect the bearing journals, flange and bolt threads. Count the axle splines, since this case is built around 30-spline internals and early 19-spline Dana 44s need different parts. Read the ratio off the axle tag or count ring and pinion teeth. Our Dana 44 axle problems and rebuild cost guide covers the common wear points, and the carrier break explainer shows how to tell which side of the 3.73 and 3.92 split you are on.
Yukon lists the YC D706024-X as a standard open case for Dana Spicer 44, 30 spline, 3.73 and down ratios only. Yukon does not publish a vehicle table for this case. The matching 30-spline open spider gear kit is listed for Dana 44s such as 1997-2006 Wrangler TJ and 1986-1993 Cherokee rear, 1994-2002 Ram 2500 front, Dodge W-series and Ramcharger fronts, 1969-1980 Chevy and GMC K-series and Blazer fronts, 1971-1979 Ford Bronco and F-series axles, and International Scout II. Jeep JK and JL axles use their own carriers, and some IFS and disconnect versions differ, so match ratio, spline count and your old case before ordering, or send us the year and VIN.

No. It is bare. It includes carrier shims, a roll pin, ring gear bolts and a cover gasket. Spider gears and carrier bearings are separate.
No. It is for 3.73 and numerically lower ratios only. Dana 44 gear sets of 3.92 and deeper need the other case series.
No. It is built for 30-spline Dana 44 internals. Early 19-spline Dana 44s need different side gears and parts.
JK and JL Dana 44 axles use their own carrier designs. Match your old case or send us your year and VIN before ordering.
Only if they are worn or you are changing ratio. If you regear and stay at 3.73 or lower, this case works; going to 3.92 or deeper requires a different case.
Use 75W-90 gear oil, or 75W-140 if your service manual allows it for towing. An open case does not need friction modifier.
