• Wear-related service issues in Dana 80 rear axles

Installation Notes

Verify axle identification before ordering, including Dana 80 (286MM) configuration and, for select Ford E-350 applications, the 4.125" pinion bearing note. Professional installation is recommended for differential service because bearing preload and setup affect final operation.
