Pros: Extra capacity for oil drain plug Does not rub on gas tank skid on aYJ Looks
Cons: Hardware was grade 5 Hard to clean
Recommended? Yes

Comments: I picked this up for the price since my axle swap budget ran low at this point. I figured I would change it in the near future and buy a steel one. To be honest on a rear Dana 44 on a YJ this worked out great and I have no plans now on swapping it out. It can take some punishment and it made it simple to swap my gear oil after a river crossing. Buy extra gear oil you will need it.

Price: $100.00
Pros: Product design and logo looks nice and mfg. product specifications are attractive.
Cons: Metal-on-metal contact (impact) between rear track bar and PN 40-2033AL
Recommended? No

Comments: I own an un-lifted stock 2011 Jeep Wrangler 2dr Sport model. Last June my OEM rear diff. cover was replaced with an G2 Axle and Gear PN 40-2033AL Aluminum Differential Cover for Dana 44 Axle Assemblies.

The rear OEM track bar hits the diff cover when I go over bumps when I'm off-roading or going over speed bumps in the city.

Regretfully I now have switch back to my OEM diff. cover or install another aftermarket cover that has the required clearance.

Price: $97.00
Pros: Great price, especially compared to the competition. High quality. Holds more oil, so the pinion bearings are certainly not gonna run dry, and the cover has a built in drain plug.
Cons: None.
Recommended? Yes

Comments: Bought the Dana 44 cover for my TJ a few months ago, and was so impressed with everything, I just bought the Dana 30 cover yesterday.

In my opinion, all the other covers on the market are way over priced and over rated.

Price: $105.99
Pros: They look good and with their fins and increased oil capacity will help your diffs run cooler.
Cons: No instructions, no torque specs and recommended fluid capacity that came with the product. Also their drain plugs do not get as much oil out of the diff as the one that is already on the housing from the factory. The drain plug location is one of the first place that a rock will hit. I am also getting some rubbing front and rear with 1.5" of lift. Good thing is that the softer aluminium was ground down by my track bar, so now it clears it...
Recommended? No

Comments: I filled them up to the filling hole like any other cover and I was rewarded with oil coming out of the breathers after a short drive. That lasted for a few days.

I also had to tighten down the fill and drain plugs on 3 occasions because of "sweat stains".

I recently flushed my diffs and after talking to the shop owner where I bought these, I decided not to fill them up to the fill hole in order to prevent the previous mess. I used about 600ml more than the factory specs, rounded off I put 2L in the Dana 30 and 2.5L in the Dana 44 of my JK.

I ended up putting some bearing grease on the plug threads to stop any leaking and that did the job.
