Overview
The G2 Ford 10.25 Inch/10.5 Inch Aluminum Cover, part number 40-2046AL, is a raw cast aluminum rear differential cover for Ford 10.25 inch and 10.5 inch Sterling rear axles. It shields the ring and pinion and is designed to help cool the gear oil for longer bearing life.
The casting is heat treated and shot peened to withstand direct impact. The cover is made for Sterling axles in the 10.25 inch and 10.5 inch sizes, so the axle name and size are the main checks.
Key features
- Cast from lightweight aluminum that helps dissipate heat
- Reinforcing ribs add rigidity
- Heat treated and shot peened construction
- Machined seal surface for a leak free fit
- Raw natural aluminum finish
Sterling axles explained
Sterling axles are often found in heavier builds, where the rear cover takes more strain from rocks and drivetrain flex. Covers in this class protect the ring and pinion and hold the gear oil, so a sound cover matters when the axle works hard. Before fitting one, confirm the axle name and size on your housing, because the wrong cover will not seal properly.
When a cover is replaced, it is a good time to replace the gasket, refill with fresh gear oil and check the axle vent. Look for oil seeping at the flange, bent or cracked edges, or bolt holes that have elongated. Keep the cover edge clean before setting the new gasket, and torque the bolts in an even pattern. Check the level again after the first few trail outings.
