Yukon Gear Master Overhaul Kit for 2017+ Ford Dana 60 Front Differential
When Ford redesigned the Super Duty for 2017, the four-wheel-drive F-250 and F-350 front axle changed with it. It is a Dana 60 with a short, reverse-rotation pinion and a 28-spline pinion shaft, and its bearings, races and seals do not interchange with the 1999-2016 front Dana 60 parts many shops still stock. If your newer Super Duty growls or whines only after you lock the hubs and shift into four-wheel drive, or the front pinion seal is wet, the Yukon Gear & Axle YK D60SR master overhaul kit is the new bearing and seal set built for this specific axle.
A reverse-rotation front axle mounts the pinion above the ring gear centerline. That raises the front driveshaft for better angles and ground clearance, and it means the ring gear is cut the opposite way from a standard rear axle. The pinion still rides on two tapered roller bearings, and the carrier still turns on two side bearings set by shims. Those bearings take the full load of the front tires when the truck plows snow, pulls a trailer up a slick ramp or claws through mud. Once they wear, the gear mesh moves out of its pattern and the front end starts to sing. Yukon's master overhaul kit for this axle replaces the carrier and pinion bearings and races with Timken parts and adds the seals and small parts a full rebuild calls for, so you can reset pinion depth, preload and backlash from scratch.
Raise the front of the truck, unlock the hubs and disconnect the front driveshaft at the pinion. Rotate the pinion by hand and rock it in and out: roughness says the pinion bearings are failing, and movement says preload is lost. Drain the oil into a clean pan and look for metal. Then pull the cover and paint several ring gear teeth with marking compound. Clean teeth with a centered pattern mean an overhaul is all it needs. If the teeth are pitted or you are changing ratios for bigger tires, order a matching reverse-cut gear set such as the 2017-22 Super Duty 4.30 gear package at the same time. Also check the hub bearings and ball joints, which can make similar noises on these trucks.
This kit is listed for the 2017-and-later Ford Super Duty front Dana 60, the short reverse axle with a 28-spline pinion. It is not for the earlier Super Duty or Ram front Dana 60; those trucks use the YK D60-F front Dana 60 and 61 overhaul kit. Gear sets for this axle use different carrier breaks depending on ratio, so note your current ratio from the axle tag or door sticker, or send us the year, model and VIN and we will confirm before it ships. More differential and transmission overhaul sets are on our rebuild kits page.
Record the original backlash, pinion depth shim and contact pattern before you take anything apart. A Dana 60 housing spreader lets the carrier come out without prying on the bearing caps, and it is needed again to set carrier preload with the new shims. Press the new races until they bottom, set pinion preload with an inch-pound torque wrench, and keep the bearing caps in their original positions. Set backlash with a dial indicator and confirm the pattern on both sides of the teeth, remembering that a reverse-cut set reads drive and coast differently from a rear axle. Refill with the gear oil grade Ford lists for your truck, then recheck the level after a short drive with the hubs locked.

No. It is built for the 2017-and-later Super Duty front Dana 60 with the short reverse 28-spline pinion. Earlier Super Duty front Dana 60 axles use different bearings and need a different kit.
It refers to the short reverse Dana 60 front axle, a reverse-rotation design with a short pinion that Ford uses under the 2017-up Super Duty.
Yes, if the teeth are not pitted or chipped. Start with the original pinion depth shim and confirm the contact pattern before final assembly.
If you have moved to larger tires, regearing now saves doing the job twice. The front and rear must use the same ratio, so order matched front and rear gear sets.
With the hubs unlocked and the transfer case in 2WD, the front ring and pinion barely turn. Once 4WD is engaged they carry load, so worn front bearings or gears only make noise then.
