Yukon Gear 1541H Alloy Replacement Right Hand Rear Axle For Dana 44 / 97+ TJ Wrangler / XJ

Snapped the passenger side shaft in a Dana 44 rear on your Wrangler TJ, or found the right rear wheel wobbling after a hard landing? Yukon YA D75786-1X is the 1541H alloy right hand rear axle for the Dana 44 used in Jeep TJ and YJ Wranglers, early XJ Cherokees and the Comanche pickup. Yukon lists it at 29-3/4 inches long with 30 splines, and the flange is drilled for both 5 x 4.5 and 5 x 5.5 inch wheel patterns.

What the right rear shaft does in a Jeep Dana 44

The rear Dana 44 under these Jeeps is semi-floating. That means the shaft is a structural part, not just a torque tube: it carries the corner weight of the Jeep on a single outer wheel bearing while it turns the wheel. The splined inner end slides into the passenger side gear of the carrier. Because the differential in these housings sits off center, the right shaft is a different length from the left (the matching left side is 29-1/4 inches), so the two are not interchangeable. 1541H is a heat-treated alloy that is tougher than a plain carbon shaft, which matters once you add a locker, taller tires or a regear that multiplies torque at the wheel.

Symptoms of a damaged right rear shaft

• The Jeep will not move with the right rear wheel lifted or on loose ground, while the driveshaft spins, pointing to a broken shaft or stripped splines.
• A clunk from the passenger side when you load and unload the throttle, from splines that have worn loose in the side gear.
• Visible wobble at the right rear wheel or measurable flange runout after a rock strike.
• Gear oil on the inside of the right rear tire or brake parts, often because a bent shaft has worn the seal.
• Grinding or growl from the right rear corner that changes when you swerve, which can be the shaft bearing rather than the gears.

How to confirm it before you buy

First make sure the housing really is a Dana 44. Most TJs and XJs left the factory with a Dana 35 or a Chrysler 8.25 rear, and neither accepts this shaft. A Dana 44 rear has 44 cast into the housing and 30-spline shafts; the Rubicon models from 2003-2006 and some other TJs got it. Pull the shaft and check for a twist in the splines, a scored bearing journal or a flange that will not run true on a dial indicator. Our Dana 35 vs Dana 44 rear axle comparison walks through identifying the housing, and the rear axle bearing noise guide helps separate a bad bearing from a bent shaft.

Fitment

Yukon's fitment table lists 1997-2006 Wrangler TJ 4WD, 1987-1995 Wrangler YJ, 1987-1993 Cherokee XJ 4WD and 1986-1992 Comanche, each with a Dana 44 rear. The title says 97 and up XJ, but Yukon only shows XJ coverage through 1993, so a later Cherokee owner should send us the year and VIN before ordering. Yukon's fitment notes describe a rear axle kit with bearing, seal, retainer and wheel studs, while the main description lists the shaft alone; confirm what you need on the old shaft before ordering extra bearings. This listing is the passenger side only. The driver side is the Yukon left hand Dana 44 TJ/XJ rear axle, and Yukon's 4340 option is the chromoly 30-spline Dana 44 rear axle if you want a stronger shaft (check its length against yours).

Install notes

• Yukon's technical note says the factory 4.10 ratio Trac-Lok axles had ABS and this shaft has no ABS tone ring. Move or add a tone ring if your Jeep uses rear wheel speed sensing.
• Bearings and retaining rings on a pressed-bearing shaft go on in a hydraulic press. A used retaining ring is never reused.
• Inspect the side gear the old shaft came out of. Chipped teeth or a worn cross shaft call for the Yukon 30-spline Dana 44 spider gear kit or a full Yukon Dana 44 master overhaul kit for the TJ Rubicon if the carrier and pinion bearings are also worn.
• Refill with 75W-90 or 75W-140 gear oil; a Trac-Lok or other clutch-type limited slip needs friction modifier.

Is this the driver or passenger side?

Right hand, which is the passenger side. It is 29-3/4 inches long; the left side shaft is a separate, shorter part.

Does it fit a Jeep XJ from 1994 or later?

Yukon's fitment table only lists the XJ from 1987-1993 with a Dana 44 rear. Send us your year and VIN if you have a later Cherokee with a swapped or optional 44.

My TJ has a Dana 35. Can I use this shaft?

No. The Dana 35 uses 27-spline shafts and a different housing. This shaft needs a Dana 44 rear with 30-spline side gears.

Will my rear ABS still work?

This shaft has no ABS tone ring. Yukon notes that factory 4.10 Trac-Lok Dana 44 axles had ABS, so a tone ring must be fitted if your Jeep uses one.

What bolt patterns does the flange take?

It is drilled for 5 x 4.5 inch and 5 x 5.5 inch patterns, so it works with stock Jeep wheels or full-size pattern wheels.

What gear oil should go in after the swap?

75W-90 or 75W-140 gear oil, with friction modifier if the carrier is a Trac-Lok or other clutch limited slip.
