Overview
The G2 Axle and Gear 40-2033ALB is a black aluminum differential cover for Dana 44 front or rear axles. It is cast from lightweight aluminum, which G2 says helps dissipate heat from the gear oil, and it carries a black powder coat finish.
The cover protects the ring and pinion and helps cool the gear oil for longer bearing life. It is made from high strength heat treated aluminum and is shot peened for impact resistance. The seal surface is fully machined for a leak-free installation, and reinforcing ribs add rigidity.
Key features

Fluid and housing care
The differential cover is the access point for the ring and pinion, and it holds the gear oil in the housing. Covers take the most abuse on rocky trails because they sit low under the axle. Aluminum covers are lighter than steel and shed heat more readily, though they can dent if struck hard, so inspect them after rough runs.
Gasket and seal condition matter as much as the cover itself. Replace the gasket whenever the cover is removed, and clean both mating faces until they are smooth and free of old sealant. Tighten the cover bolts evenly in a crisscross pattern so the cover seats flat, then check the fluid level after the first drives.
Gear oil should be changed on a schedule suited to your use. Look for metal flakes or a dark, burnt smell when draining, as these point to wear in the gears or bearings. A cover that has taken a hit should be checked for cracks around the ribs and mounting bolts before it goes back on.
