Yukon YK D44JL-FRONT – Master Overhaul Kit for the Front Dana 44/M210
The Yukon YK D44JL-FRONT is a Master Overhaul Kit designed for servicing and setting up the front Dana 44/M210 210 mm differential found in compatible Jeep Wrangler JL and Jeep Gladiator JT applications.
Key benefits
- Timken carrier and pinion bearings with matching races,
- components required for differential setup during a rebuild or gear installation,
- application-specific package for the front Dana 44/M210,
- both carrier and pinion bearing components included.
What is a Master Overhaul Kit used for?
This kit provides the bearing, sealing and setup components typically replaced when rebuilding a differential or installing a different ring and pinion ratio. It is intended for vehicles equipped with the matching front Dana 44/M210 axle.
The ring and pinion gear set itself is not included. If you are changing the axle ratio, the correct ring and pinion set must be selected separately.
Jeep JL and JT fitment
The primary fitment criterion is the front axle type: Dana 44/M210, 210 mm. The kit is catalogued for Jeep Wrangler JL and Jeep Gladiator JT applications, but axle configuration should always be verified before ordering rather than relying solely on model year or trim level.
Kit contents
- carrier bearings and races,
- pinion bearings and races,
- pinion seal,
- complete shim kit,
- ring gear bolts,
- pinion nut,
- thread-locking compound,
- gear marking compound and brush.
Important: the YK D44JL-FRONT version is supplied without axle seals. If the axle seals are being replaced during the same service, they should be selected separately.
