Yukon Gear Replacement Standard Open Carrier Case For Dana 60 / 4.10 & Down
When a Dana 60 open differential lets go, the case often takes the damage with it: cracked cross-pin bores, galled side gear pockets, or a ring gear flange that pulled loose bolts. Yukon YC D707212 is a new bare standard open carrier case for Dana 60 axles geared at 4.10 or numerically lower, such as 3.54, 3.73 and 4.10. Yukon lists it for both semi-float and full-float housings, including ABS-equipped axles, and gives it as 2-1/8 in. tall.
The carrier is the cast housing that the ring gear bolts to. It spins on two tapered carrier bearings in the axle housing and holds the cross pin, the two pinion (spider) gears and the two side gears that the axle shafts slide into. In an open differential nothing inside the case limits wheel spin, so the case is simple, but it still carries the full torque of the ring gear through its flange and cross pin. Dana 60 ring gears are made in two thicknesses. Ratios of 4.10 and lower use one ring gear mounting position and ratios of 4.56 and higher use another, so carriers are sold for one side of that break or the other.
Drain the gear oil and look at the metal on the magnet. With the cover off, check spider gear backlash by holding one axle and rocking the other, and look at the cross pin and its lock bolt. Once the carrier is out, inspect the side gear bores, thrust surfaces and the ring gear flange. Small surface marks can be cleaned up, but a cracked or egg-shaped bore means a new case. Our spider gear failure guide walks through what that damage looks like.
This case fits Dana 60 axles with a 4.10 or lower ratio, in semi-float and full-float housings, and it is listed as working with ABS. It will not take a 4.56 or higher ring gear; that needs a 4.56-up case. Because it is sold bare, the spline count is set by the side gears you install, not by the case. Check your ring gear ratio stamped on the gear, count your axle splines, and if your axle has an ABS tone ring on the carrier, compare it to your old case before you order. Our carrier break guide explains how to tell which side of the Dana 60 break you are on. Send us the axle tag or your year and VIN if you want us to check.
A bare case needs a full set of internals. Order a Dana 60 spider gear kit for 30-spline axles or the 35-spline equivalent, new carrier bearings such as the Dana 60 carrier bearing kit, and new ring gear bolts. Moving to a new case means the ring gear backlash and carrier bearing preload must be set again, so a Dana 60 rear master overhaul kit with shims and seals is usually the cleaner path.
The Dana 60 carrier is held in by bearing preload, so the housing must be spread slightly to remove and install it; a Dana 60 housing spreader keeps you from prying on the bearing caps. Press the carrier bearings on squarely, torque the ring gear bolts in a cross pattern with thread locker, and confirm backlash and gear pattern before the cover goes on. Refill with 75W-90 or 75W-140 gear oil as your axle calls for.

No. It is a bare carrier case. Plan on a spider gear kit that matches your axle spline count, carrier bearings and ring gear bolts.
No. This case is for 4.10 and lower ratios. Dana 60 gears of 4.56 and higher use a thicker ring gear and need a 4.56-up carrier.
Yes. It is listed for semi-float and full-float Dana 60 housings. For a front axle, compare it with your original carrier before ordering. Confirm the ratio and spline count, and compare any ABS tone ring with your old carrier.
Yes. A new case changes the ring gear position slightly, so backlash and carrier bearing preload must be checked and shimmed, and the gear pattern confirmed.
If you want traction off-road or in snow, a locker or limited slip replaces the case entirely. If you want factory open-diff behavior at the lowest cost, this case with new internals is the direct repair.
