On a Bronco crawling over rock, the rear differential is the lowest thing under the axle and the first thing to hit. The stock cover also makes checking fluid level a guess.
The AEV Rear Differential Cover is cast from high-strength nodular iron for the Dana M220, with a reinforced bottom edge and recessed hardware. A fluid level port sits at the factory level, and an oversized top fill port lets you add fluid on the trail or check the ring gear and spot water without pulling the cover.
Bolt it on, fill to the port and drive.
