Yukon Gear 1541H Right Hand Replacement Assembly For Dana 30 (84-90 XJ or 97+ TJ/Wrangler)

A snapped passenger-side front shaft is one of the most common trail breaks on a Jeep Cherokee XJ or Wrangler TJ, especially once bigger tires and a front locker go on. Yukon YA D75814-2X is a complete right-hand Dana 30 front axle assembly in 1541H alloy: inner shaft and outer stub joined by a 5-760X size U-joint, 27 spline on both ends, ready to slide back into the tube.

What the right-hand axle assembly does in a Dana 30

The Dana 30 front in these Jeeps is a solid axle with open steering knuckles. Each side uses a two-part shaft: the inner shaft runs from the carrier side gear out through the tube, and the outer stub passes through the knuckle and unit bearing to drive the wheel. The U-joint between them lets the wheel steer while it is being driven. On the passenger side the inner shaft is longer than the driver side because the carrier sits off center, so the two sides are not interchangeable.

1541H is a stronger alloy than the plain carbon steel used in many stock shafts. It does not make a Dana 30 bulletproof, but it gives the shaft more margin before it twists or snaps, which matters when a locker sends equal torque to both front wheels.

Symptoms of a failed or failing shaft

• Loud bang on the trail, then the front end stops pulling on the passenger side.
• Clicking or popping while turning in 4WD, often a worn or seized U-joint at the knuckle.
• Twisted or chewed splines when the shaft comes out, which can hide behind an intermittent clunk.
• Gear oil weeping from the passenger knuckle area, a sign the inner tube seal has failed and should be replaced with the shaft.
• Vibration that changes with steering angle in 4WD.

How to confirm before buying

Lift the front, set the transfer case to 4WD, and rotate the passenger wheel while watching the U-joint through the knuckle. Any play in the joint, a bent ear, or a stub that turns while the inner shaft does not means the assembly is done. Our Dana 30 front axle problems guide covers the related bearing and gear failures, and U-joint replacement symptoms helps you separate a bad joint from a bad shaft.

Fitment

Our title lists the 1984-1990 XJ and 1997-up TJ. Yukon's own fitment table goes wider: 1984-2001 Cherokee XJ 4WD, 1987-1995 Wrangler YJ, and 1997-2006 Wrangler TJ, all Dana 30 front, right-hand side, 27 spline, without ABS. Two things to check before you order. First, Yukon's description gives a 32.4 inch length while its fitment table says 38.5 inches, so measure your old assembly end to end. Second, if your axle has ABS or a vacuum disconnect on the passenger tube, send us your year and VIN so we can confirm the right shaft. The TJ Rubicon used a Dana 44 front and does not take this part. More driveline parts are in our hard parts category.

Install notes

• Remove the passenger hub and unit bearing, then pull the assembly straight out so the inner splines do not drag the tube seal.
• Fit a new inner tube seal before the new shaft goes in. Spreading the housing is not needed for this job, but if you are into the carrier at the same time a Dana 30-80 housing spreader makes carrier removal far easier.
• Clean the hub bore and use new hub bolts if the old ones are rusted. Torque the axle nut to the value in your service manual.
• Check the front differential fluid level after install and top up with the gear oil your owner's manual lists. If the oil is milky or has metal, the bearings are next: see the Dana 30 front master bearing kit.
• Re-gearing for larger tires? Do it while the axle is apart with a Dana 30 reverse rotation 4.56 gear set, after confirming your axle's rotation.

Will this fit my Jeep Cherokee XJ?

Yukon lists it for 1984-2001 Cherokee XJ 4WD with the Dana 30 front, right side, 27 spline, without ABS. If your XJ has ABS or a vacuum disconnect, send us your year and VIN before ordering.

Does it fit a TJ Rubicon?

No. The TJ Rubicon came with a Dana 44 front. This assembly is for the Dana 30 front used in the standard 1997-2006 Wrangler TJ.

Is the U-joint included?

Yes. It is a complete right-hand assembly: inner shaft, outer stub and a 5-760X size U-joint, 27 spline on both ends.

How long is it?

Yukon lists 32.4 inches in its description and 38.5 inches in its fitment table. Measure your old assembly before ordering so you know it matches.

What should I replace with it?

Install a new inner tube seal every time the shaft comes out, check the unit bearing for play, and top up the front differential with fresh gear oil.
