Yukon Gear Chromoly Front Axle Kit for Dana 30 w/27 Spline & 1310 U-Joints
A snapped front shaft on a Jeep Dana 30 usually happens the same way: bigger tires, a locker or a hard bounce with the wheel turned, and the stock inner shaft or outer stub lets go at the U-joint ear. The Yukon Gear & Axle YA W24110 kit replaces both sides of a 27-spline Dana 30 front in Wrangler YJ and TJ, Cherokee XJ and early Grand Cherokee ZJ builds with 4340 chromoly shafts and new Spicer U-joints, all in one box.
A Dana 30 front uses a two-part shaft on each side: an inner shaft splined into the differential and an outer stub that drives the wheel hub, joined by a U-joint inside the steering knuckle so the wheel can turn and still be driven. The factory shafts are plain carbon steel and the joint area takes the worst of the load at full lock. Yukon builds these from high-tensile 4340 chromoly with cold roll formed splines and induction heat treating. The kit includes two 27-spline outer axles, a 27-spline 32.36 inch right inner, a 27-spline 16.63 inch left inner, 1310/760X series Spicer U-joints, and a Yukon vacuum disconnect block-off kit with axle seals. The long one-piece right inner and block-off kit let you retire the factory vacuum disconnect on axles that have one; our chromoly vs stock axle guide covers when the upgrade pays off.
With the front on stands and the transfer case in neutral, turn each front tire by hand and watch whether the front driveshaft moves. Pull the hub on a suspect side to inspect the joint and the stub splines. Check the inner seals while the shaft is out. Our Dana 30 front axle problems guide walks through bearing noise, seal leaks and shaft failures, and the Dana 30 vs Dana 44 comparison helps if you are deciding whether to keep the 30 at all.
Yukon catalogs YA W24110 for the Dana 30 front in 1984-2001 Jeep Cherokee XJ, 1987-1995 Wrangler YJ, 1997-2006 Wrangler TJ and 1993-1998 Grand Cherokee ZJ with 4WD. It is a 27-spline kit. Count your inner shaft splines and confirm your U-joint size before you order; 30-spline Dana 30 and Dana 44 fronts take different shafts, and a 760X joint is not the same as the smaller 260X used in some early housings. If you are unsure which axle is under your Jeep, send us the year and VIN. Browse matching front axle parts in our rebuild kits category.
Remove the caliper, rotor and three unit bearing bolts per side, then slide out the outer shaft assembly. The inner shafts pull from the differential once the outers are out. Replace the inner axle seals every time a shaft comes out; the Dana inner axle seal installer seats them square so the new shaft does not wipe them out on the way in. Press the supplied U-joints with a proper tool such as the ball joint and U-joint press kit, and check that the joint moves freely after the clips are in. On a disconnect axle, follow the block-off kit instructions and cap or route the vacuum lines so the shift motor no longer cycles. Torque the unit bearing bolts to the factory spec, top off the front differential with 75W-90 gear oil, and if a front locker is part of the plan, the Eaton ELocker4 for 27-spline Dana 30 pairs with these shafts. Owners going further can add the Yukon Spin Free hub conversion to replace the unit bearings with locking hubs. For the joint work itself, see our U-joint series guide.

Yukon lists it for the Dana 30 front in 1984-2001 Cherokee XJ, 1987-1995 Wrangler YJ, 1997-2006 Wrangler TJ and 1993-1998 Grand Cherokee ZJ 4WD. It is for 27-spline axles only.
Yes. The kit includes two outer axles, a 32.36 inch right inner, a 16.63 inch left inner and the Spicer U-joints, so both sides of the front axle are done at once.
Some XJ and YJ Dana 30 axles have a factory vacuum center disconnect on the right side. The block-off kit, with the one-piece right inner shaft, eliminates it so the front axle is always connected when the transfer case is in 4WD. Axles without the disconnect do not need it.
Yes. Any time the inner shafts come out, install new inner seals. A worn seal leaks gear oil into the knuckle and onto the brakes.
A 75W-90 gear oil is the usual fill for a Dana 30 front. Check the front differential level after the shafts are installed, since oil can be lost when the inner shafts are pulled.
