Yukon Dana 44 Rear Master Overhaul Kit for Jeep JK Rubicon '07-'17
YK D44-JK-RUB
The Yukon Dana 44 Rear Master Overhaul Kit for 2007–2017 Jeep JK Rubicon provides the bearings, races, seals, shims, and setup hardware commonly replaced during a rear differential rebuild or gear installation. Designed specifically for the factory Dana 44 rear axle used in JK Rubicon models, this kit is a complete service package for restoring proper bearing support, preload, backlash, and sealing during differential work.
JK Rubicon rear axles often see added load from larger tires, deeper gearing, lockers, towing, and off-road use. Replacing the major wear and setup components during a rebuild helps give the ring and pinion a stable foundation and makes it easier to establish the correct differential setup from the start.

FAQ
What is included in a master differential overhaul kit?
This kit includes the major bearings, races, seals, shims, hardware, and setup materials commonly replaced when rebuilding the rear differential or installing a new ring and pinion.
Does this kit include Timken bearings?
Yes. The supplied product information identifies Timken bearings and races as part of the overhaul kit.
Will this fit the front Dana 44 in a JK Rubicon?
No. This kit is designed for the rear Dana 44. It does not fit the front reverse-rotation Dana 44 application.
Should the bearings and crush sleeve be replaced during a gear install?
These components are commonly replaced during differential service so pinion preload, carrier support, and gear setup can be established with fresh service parts rather than reused wear components.
Why is differential setup important on a JK Rubicon rear axle?
Proper bearing preload, backlash, and gear tooth contact are critical to ring-and-pinion life and noise control, especially in vehicles running larger tires, deeper gear ratios, lockers, or frequent off-road use.
