Applications

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

Tech Note 2: Matching Cup
The matching Bearing Cup will vary by application, but for Dana-Spicer Model 60, 61, and 70 Differentials, the matching Cup is QU50397. If you need two Cups and 2 Cones, see QU40184 Differential Bearing Set which includes two each QU50397 and QU50398. Most wheel bearing applications will have QU50396 as the matching Cup.

Tech Note 3: Differential Set Up
If you are installing a new gear set and/or a new differential you will need QT1098 Differential Master Bearings for Dana axles and a dial indicator all axle makes. If one or both of your differential bearing cups wore sideways into the housing or a diff bearing spun on the differential and tore the shims, you will also need these tools to determine the correct shim packs. Both conditions are very common on rear axles especially with Diesel powered trucks.

Tech Note 4: Diff Bearing Installer
Use QT1158 Installer to install QU50398 Bearing on a differential.

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