Yukon Dana 30 Master Overhaul Kit for Jeep JK Non-Rubicon - Rev. Rotation, '07-'17
YUKYK D30-JK
This Dana 30 Reverse Rotation Master Overhaul Kit from Yukon is designed for rebuilding the front differential in 2007–2017 Jeep JK Wrangler non-Rubicon models equipped with the Dana 30 front axle. The kit includes Timken bearings and races along with seals, shims, hardware, and setup components commonly replaced during differential service.
Proper bearing preload and gear setup are critical on reverse rotation Dana 30 front axles, especially in lifted JK applications running larger tires where additional driveline load accelerates wear on bearings and sealing surfaces.
Includes:
- Carrier Bearings and Races
- Pinion Bearings and Races
- Pinion Seal
- Axle Seals
- Complete Shim Kit
- Ring Gear Bolts
- Pinion Nut
- Crush Sleeve
- Oil Baffles and Slingers
- Thread Locker
- Gear Marking Compound with Brush
- Differential Gasket

Tech Insight
Reverse rotation Dana 30 front axles used in Jeep JK models rely heavily on proper bearing preload, pinion depth, and backlash settings to maintain quiet operation and long gear life. Once larger tires and suspension lifts are added, the increased leverage and driveline angle changes place additional stress on carrier bearings, pinion bearings, and seals.
A complete overhaul kit allows all critical wear components to be replaced during differential service rather than reusing worn bearings and setup hardware. Replacing crush sleeves, shims, and seals during gear installation is essential for maintaining consistent preload and preventing premature gear wear or fluid leakage.
