Overview
The Dana Spicer Dana 44 Differential Drive Pinion Oil Deflector, part number 2005565, is a front-position deflector for Dana 44 and Ultimate 44 axles. It fits the 2007 to 2018 Jeep Wrangler JK, in 2-door and 4-door body styles.

How the pinion deflector works
The pinion deflector sits in front of the pinion seal and throws gear oil away from it as the gears turn. Without a sound deflector, oil can splash straight onto the seal and find its way past the lip. That is why a worn or bent deflector is a common cause of seal leaks around the front of the axle.
The deflector is a simple part, but its position matters. When the pinion seal or bearings are serviced, the deflector should be checked for cracks and a flush fit against the housing. Use a fresh seal and clean the mating surfaces so the deflector seats correctly. Shops often replace it during seal work.
- Check for cracks along the edge
- Confirm the deflector sits flush against the housing
- Replace it during pinion seal service
