Pinion Nuts & Seals Overview
The pinion nut sets the pinion bearing preload and the pinion seal keeps gear oil in the differential; a leaking seal or loose nut causes leaks and driveline problems. Van Horn Truck Parts carries pinion nuts and seals cross-referenced to Dana, Meritor, and OEM part numbers.
Match by your axle make and model, and follow the preload procedure on reassembly.
Mechanic & Fitment Specs:
- Match by: Axle make/model
- Cross-references: Dana, Meritor, OEM
- Buying tip: Follow the axle maker's pinion preload procedure when torquing the nut
