Yukon Jeep JK Rubicon Dana 44 Front Bearing Install Kit - Reverse Rotation
BK D44-JK-REV-RUB
The Yukon Jeep JK Rubicon Dana 44 Front Bearing Install Kit provides the essential bearings, races, seals, and setup components needed when servicing or regearing the reverse rotation Dana 44 front differential. Designed for Jeep Wrangler JK Rubicon applications, this kit is a practical option for builders replacing worn differential bearings or installing new ring and pinion gears without purchasing a complete master overhaul kit. It supplies the major bearing and sealing components while leaving out the shim kit for builders who already have the necessary setup shims.
Proper differential setup matters, especially on JK Rubicon front axles running larger tires, locking differentials, and lower gear ratios. This Yukon bearing kit includes carrier and pinion bearings with matching races, a pinion seal, crush sleeve, oil baffles and slingers, and gear marking compound to help complete the installation. Whether you're rebuilding a worn front differential or setting up new gears, correct pinion depth, bearing preload, backlash, and gear contact pattern are essential for quiet operation and long-term reliability.
Includes:
- Carrier Bearings & Races
- Pinion Bearings & Races
- Pinion Seal
- Crush Sleeve
- Oil Baffles & Slingers
- Gear Marking Compound & Brush
Important: This is a bearing installation kit, not a master overhaul kit. Shims are NOT included. Existing serviceable shims or a separately purchased shim kit are required to complete differential setup. Ring and pinion gears are sold separately.

Fitment Notes:
- Designed for Jeep JK Rubicon Dana 44 front differential applications
- Reverse rotation / high-pinion axle configurations only
- Compatible with differential bearing replacement and ring and pinion installation
- Does not include differential setup shims
- Requires existing serviceable shims or a separately purchased shim kit
- Not intended for Jeep JK Non-Rubicon Dana 30 front axles
- Not intended for Dana 44 rear differential applications
- Verify axle identification and bearing compatibility before ordering
- Professional differential installation and gear setup are recommended
Builder Note: This kit makes sense when you already have the shims needed to set pinion depth and carrier preload. If you're starting a complete differential rebuild without setup components on hand, a master overhaul kit may be the better option.
FAQ
What is the difference between a bearing install kit and a master overhaul kit?
A bearing install kit provides the major bearings, races, and selected installation components needed for differential service. A master overhaul kit typically includes additional setup parts such as shims and hardware. This Yukon bearing kit does not include shims, making it a good option for builders who already have the correct setup components.
Does this kit include differential shims?
No. Shims are not included. You'll need existing serviceable shims or a separately purchased shim kit to establish proper pinion depth, bearing preload, and gear backlash during installation.
Will this kit fit my Jeep JK Rubicon front axle?
This kit is designed for compatible Jeep Wrangler JK Rubicon models equipped with a Dana 44 reverse rotation front differential. Verify the installed axle before ordering, especially on modified or axle-swapped Jeeps.
Will this bearing kit fit a Jeep JK Non-Rubicon?
Not if the Jeep has the factory Dana 30 front axle. This kit is designed specifically for the Dana 44 front differential used in JK Rubicon applications. The axle model and bearing dimensions must match.
Can I use this kit when installing new ring and pinion gears?
Yes. This bearing install kit provides the major bearing and sealing components needed during a gear installation. However, shims and any additional required installation hardware must be available separately.
Does this kit include the ring and pinion gears?
No. This listing includes differential bearings, races, seals, and selected setup components only. Ring and pinion gears are sold separately.
Why is proper differential bearing preload important?
Correct bearing preload keeps the carrier and pinion properly supported under load. Too little preload can allow unwanted movement, while excessive preload can generate heat and accelerate bearing wear. Proper setup is critical for gear life, especially on Jeeps running larger tires and locking differentials.
What tools are needed to install this bearing kit?
Differential service typically requires a bearing press or suitable installation tools, bearing pullers, dial indicator, inch-pound torque wrench, and gear marking compound. Accurate pinion depth, backlash, preload, and contact pattern adjustments are essential for reliable operation.
Should I replace differential bearings when regearing my Jeep?
Replacing worn bearings and races during a gear installation is recommended. New bearings provide a consistent foundation for establishing proper preload and gear alignment, helping reduce the risk of noise, premature wear, and differential failure.
