Applications

Tech Note 1: Matching Cup
Always replace the cup and cone at the same time. The matching Bearing Cup for Dana axles is QU50409.

Tech Note 2: Installer
Use QT1003 Bearing Installer to seat this bearing on your pinion gear.

Tech Note 3: Alternative Bearings/Cups
Standard Dana-Spicer Model 70B and 70HD use this bearing and QU50409 4-1/8" diameter bearing cup. You will also find Dana 70 and 70U axles that use a 3-1/2" bearing cup (QU50406) plus QU50408 bearing.

Tech Note 4: Dana 70 Axles
Until the 1990's all Dana-Spicer Model 70 series axles used shims between the inner Pinion Bearing and the Pinion Head to set the pinion rotating preload. The combined thickness of shims, and any inner Slinger or baffle is what will set the pinion depth. Gear sets and Pinion Shim Kits may fit several applications, so you may find you have a kit with an inner Slinger or baffle that differs from original. As a rule, unless otherwise instructed, only use an inner baffle or Slinger if your axle was originally built with the exactly the same type of part. The only exception would be when the gear or shim manufacturer specifically instructs you to use a different combination than original equipment.
