Yukon Gear Replacement Ring & Pinion Gear Set For Dana 44 Short Pinion Rev. Rotation / 4.11
If your 2007-2017 Jeep Wrangler JK Rubicon has a front axle that howls in 4WD, a ring gear with chipped teeth after a hard trail day, or a pinion that clunks with play, this is the stock-ratio gear set to put it back together. The Yukon Gear & Axle YG D44RS-411RUB is a 4.11 ring and pinion for the Rubicon's front Dana 44, which is a short pinion, reverse rotation axle. It keeps the factory ratio, so the front still matches the Rubicon rear and the factory locker carrier stays in service.
The JK front driveshaft spins the opposite way from the rear, so the Rubicon front Dana 44 uses reverse rotation gears. The pinion sits above the ring gear centerline, which loads the strong drive side of the teeth when the Jeep pulls forward in 4WD. A standard rotation Dana 44 set would be running on its weaker coast side and is the wrong part here. This axle is also a short pinion design, so long pinion Dana 44 gear sets do not interchange. Yukon lists this set with an 8.50 in. ring gear, a 24 spline pinion and 10 ring gear bolts. The pinion splines must match the yoke you are reusing.
Yukon's spec table files this part under a 4.10 gear ratio, the ratio Rubicon JKs used from the factory. That is what makes it a straight replacement rather than a re-gear: no carrier change, no tire size math, and no reprogramming for a new ratio.
Drive the same road in 2WD and 4WD High. Noise that appears only in 4WD lives in the front axle or front driveshaft; noise in both modes is more likely the rear axle or transfer case. Our guide to whine on acceleration versus deceleration explains what each pattern means. Pull the cover and look at the teeth before ordering. If the Jeep has been re-geared before, count the ring and pinion teeth or read the stamping on the ring gear, because a previous owner may have changed ratios.
The fitment chart for YG D44RS-411RUB lists the 2007-2017 Jeep Wrangler JK 4WD with the Dana 44 reverse rotation Rubicon front. It does not fit the non-Rubicon JK front, which is a Dana 30, and it does not fit the JL or JT, which use different 210mm and 186mm front axles. The chart stops at 2017, so for a 2018 JK send your year and VIN before ordering. Read the axle tag to confirm the axle and ratio.
If you are going bigger on tires instead of rebuilding stock, compare the 4.56 short pinion reverse set, the 4.88 JK Rubicon front set and our JK regear buyer's guide. More axle parts are in differential hard parts.
The gear set comes without bearings, so order a front master kit with it, such as the USA Standard JK Rubicon front overhaul kit or the Revolution JK Rubicon front master install kit. Yukon's setup chart for the D44 JK lists a .042 in. OEM depth shim, 20-30 in-lb pinion bearing preload with new bearings (10-15 with used), ring gear bolt torque by bolt size (75 ft-lb for 7/16 in., 135 ft-lb for 1/2 in.) and 80 ft-lb on the bearing caps. Set pinion depth first, then preload, then backlash, and read the contact pattern on both sides of the teeth. The Dana 44 carrier is shim-preloaded, so a case spreader helps.
Fill with 75W-90 or 75W-140 gear oil. Break the gears in gently: about 15-20 easy miles then let the axle cool, no hard acceleration for 100 miles, at least 500 miles before towing, and an oil change at 500 miles.

No. Non-Rubicon JKs use a Dana 30 front. This set is for the Rubicon's front Dana 44, which is a short pinion, reverse rotation axle.
Yes. Yukon's specifications list this part as a 4.10 gear ratio, the ratio Rubicon JKs came with, so it matches the factory rear and carrier.
Not when you are replacing stock Rubicon 4.10 gears. The ratio does not change, so the factory locker carrier is reused. A carrier is only needed if you change ratio across the carrier break.
A JK Rubicon front master overhaul or install kit with pinion and carrier bearings, shims, crush sleeve and seals. Inspect the inner axle seals and ball joints while the axle is apart.
75W-90 or 75W-140 gear oil, filled to the bottom of the fill hole. Change it after the first 500 miles to remove break-in wear.
