Revolution Gear & Axle 87-06 Wrangler TJ Dana 44 Chromoly Disc Brakes Discovery Series Rear Axle Kit
A Wrangler with a Dana 44 rear axle and rear disc brakes that has snapped a shaft on the trail, has a rotor that wobbles after a hard hit, or is getting bigger tires and a locker needs shafts that can take more abuse than the factory parts. Revolution Gear & Axle kit DC-D44-TJ-1 is the disc brake version of the Discovery Series rear axle kit for 1987-2006 Jeep Wrangler Dana 44 axles. You get a pair of 4140 chromoly rear shafts with the wheel bearings, seals and retainers already pressed on, plus ten wheel studs packed loose.
The rear Dana 44 under a TJ or YJ is a semi-float axle. Each shaft does two jobs at once: it carries torque from the side gear in the differential out to the wheel, and the bearing pressed onto its outer end carries the weight of that corner of the Jeep. That is why a bent shaft shows up as a wobble at the wheel and a bad bearing shows up as a growl. On a disc brake axle the rotor sits directly on the shaft flange, so any flange runout goes straight into the rotor and the pads. Revolution makes these shafts from 4140 chromoly and drills each flange for both the 5x4.5 Jeep pattern and the 5x5.5 pattern, so you can keep stock wheels or move to 5x5.5 wheels later.
Check the axle first. Plenty of Wranglers left the factory with a Dana 35 rear, which takes completely different shafts, so read the axle tag or look at the cover shape; our Dana 35 vs Dana 44 guide shows how to tell them apart. Next, confirm the brakes. Pull a wheel: a caliper and rotor means this disc kit, while a drum means the drum brake version of this kit. Then pull the caliper and rotor, put a dial indicator on the flange and spin it to check runout, and rock the flange to check bearing play. If a shaft broke, drain the diff and inspect the side gears and carrier.
Revolution lists this kit for 1987-2006 Jeep Wrangler with a Dana 44 rear axle and rear disc brakes, which covers YJ, TJ and TJ Unlimited Jeeps when they carry a Dana 44 and a disc brake rear. Rear discs on a Dana 44 Wrangler can be factory or a later conversion, and conversion brackets vary, so check that your caliper bracket mounts the same way your old shafts did before you order. These are the standard spline shafts for a stock Dana 44 carrier; if you run an aftermarket 33-spline locker or carrier, use the 33-spline TJ rear axle kit instead. Count the splines on your old shaft if you are not sure, or send us your year, VIN and axle tag. Swapped axles from other Jeeps should be measured before ordering.

DC-D44-TJ-1 is the kit for a Dana 44 rear with disc brakes. DC-D44-TJ-2 is the same style of kit for a Dana 44 rear with drum brakes. Pull a wheel and look at the brakes to pick the right one.
No. It only fits a Dana 44 rear axle. Many YJ and TJ Wranglers came with a Dana 35, which uses different shafts.
Two 4140 chromoly rear axle shafts with the bearings, seals and retainers already pressed on, and ten wheel studs that ship uninstalled so they are not damaged in transit.
The flanges are drilled for both 5x4.5 and 5x5.5, so they work with stock Jeep wheels or 5x5.5 wheels.
Revolution says to install the studs with red thread locker and torque them to 90 ft-lb before the shafts go into the axle.
Only if your carrier or locker is a 33-spline aftermarket unit. A stock Dana 44 carrier uses the standard spline shafts in this kit. Count the splines on your old shaft to be sure.
