Overview
The G2 Axle & Gear Hammer Differential Cover for Dana 60/70 (gloss black, part 40-2034ALB) is a gloss black cast aluminum cover for front and rear Dana 60 axles.
The aluminum body helps cool the gear oil and protects the ring and pinion, which supports bearing life. The heat treated aluminum is designed to resist direct hits, and the powder coat gives the cover its gloss black finish.
The cast aluminum body carries the cooling role, while the gloss black finish mainly changes how the cover looks on the axle. Gear oil volume is standard on this cover, so the fill level and dipstick are the practical checks after installation.
Key features
- Cast aluminum body built to help cool the gear oil
- High strength heat treated aluminum
- Gloss black powder coat
- Standard oil capacity
- Front and rear axle application
Cover maintenance and fluid checks
A differential cover does more than seal the housing. It is the access point for fluid checks, and it protects the ring and pinion from debris and impacts. Because gear oil is standard capacity on this cover, the fill level is the number to watch after installation. Low fluid runs hotter and wears gears faster, so a quick dipstick check after the first drives is a good habit, especially on axles that see heavy towing or trail work.
Cover removal is the moment to inspect and refresh the seal. Clean both mating surfaces thoroughly, replace the gasket when the cover comes off, and tighten the bolts evenly so the cover seats flat. Look at the oil that drains out for metal flakes or a burnt smell, since either can point to gear wear before a failure shows up.
- Replace the gasket each time the cover is removed
- Check the fill level after the first few drives
- Look for metal flakes in drained oil
