Tech Note 1: Always Replace
Always replace the cup and cone at the same time.

Tech Note 2: Matching Bearing Cup
The matching Bearing Cup will vary by application, but for most Dana-Spicer Model 44 Differentials, the matching Cup is QU50537.

Tech Note 3: Confirm Correct Bearing
Early production Dana 44 axles used QU50683 Small ID Differential Side bearing which has an inside diameter of 1.688". Later production axles use QU50538 Large ID Side Bearing with a 1.796" ID. For most front axles, the changeover year was 1967. In most cases, rear axles continued to use the small ID bearing into the early 1970's. If possible, confirm which bearing you need before ordering!

Tech Note 4: Bearing Installer
Use QT1115 Installer to install QU50538 Bearing on a differential.

Tech Note 5: Tech Help
Rebearing service procedures are covered in my TM4400 Pinion and Differential Bearing Service on Dana-Spicer Monobeam Axles.
