Style: Fits Ford 8.8"
No drain plug on the Ford 8.8 cover which totally defeats the purpose of a replacement cover! As you can see in the pictures the cover has a spot where the drain plug should be but Yukon never put it in. The hardware kit even comes with 2 plugs but the cover only has one hole so something isn’t correct here. False advertising and I will need to return it and get one with a drain plug

Style: GM 14T 3/8" Bolts
I put this diff cover on my GMC K2500 4wd pickup. First off, I bought this because I'm an idiot and while doing the last drain and fill on my differential, I managed to dislodge the glued in magnet at the bottom of the differential housing, so I was on the hunt for a diff cover that had magnetic drain and fill plugs to make up for this misdeed. You can see I just stuck a big magnet on the old cover with the 'before' picture, it worked, I guess I didn't need the cover but hey I have it now! Second, Yukon is /TOTALLY WRONG/ on their website, my truck is a 98' and they said it took 3/8" bolts so that's the one I ordered without double checking, its totally wrong, trust me, you want M8-1.25, 25mm length! You can see in the pictures that I had to go get different bolts and some washers. I actually like the look of the black steel bolts with the polished washers behind them more than the shiny stainless hardware Yukon provides. Third, there's really no provision for factory brake line mounts, you'll need one 30mm+ bolt to re-hang the brake line distribution block. Yeah yeah, I get it, its a cover for /hard core 'bro-dudes' in bro-dozers/ and brakes are for suckers and losers but I'm just saying that a cast in indent on one of the top bolt holes would be great for sinking a brake line tab into and it'd make the install on any vehicle look that much cleaner. Fourth, the drain and fill ports are just straight threaded holes with big grub screws and there's two kinda silly design flaws with that: There's no sealing surface other than the threads first off, the grub screws don't seat against anything, they don't have flanges with O rings or crush washers, its /going/ to seep oil past those threads and thats stupid so I put gas-line Teflon tape on the threads. Second, the heads of the grub screws are allen key hex, WHY? Why not just a 3/8" square just like the fill port on the input side of the diff!? That's just silly and annoying. The interior design of the cover seems to promote the same fluid paths as the original stamped steel cover and that's good, its not a flat back design that's just going to whip up the oil into a froth, partially why I bought it. I used a Lubelocker gasket, the mating surface on the cover is rough cast so I doubt you'd have much luck at all using any of the paper gaskets, if you are one of those sorts of person that smears RTV all over... look, you do you but that isn't me. My truck is used for towing and hauling, 80% of the time its hooked up to a trailer, 10% of the time its full of stuff in the bed, the other 10% of the time its making a mad dash for the gas pump because its a big block with 4.10 gears. I didn't buy the cover because I go offroad, or because I thought it'd provide extra cooling or capacity, I'm sure its wishful thinking to imagine it'd make the housing stiffer too, I bought it because it was one of the only covers for a 14 bolt GM with a curved interior for proper lubrication channeling and magnets. Does it look cool? Oh totally, this thing looks awesome, that's why people buy these things usually, I'm sure its tough, I weighed it, was 19.3lbs as delivered without any hardware, 21lbs with the hardware. Should you buy it? Sure, why not, it ran me $144, the Lubelocker gasket was $30, and 4 quarts of full synth 75w140 was about $60, all in it was $234 for a pretty average 'install' with all supplies except for time and tools accounted for. Do you have $250ish dollars to spend and do you want to bling out your truck or do you keep bashing stock diff covers and denting or breaking them open? Sure, buy it, but also please get a spotter or something and stay off the rocks jeez... 4 stars for being wrong and having really obvious and simple to resolve design deficiencies. Correct the info, seat or seal the drain and fill ports, create a brake distribution block provision?, machine the mating surface seriously what why did you not do this? Oh also please stop painting the inside of stuff that holds oil and gets hot, that paint could flake and fail at some point and your gears and bearings are going to be displeased if that happens. Who knew so much could be said and so much could be gleaned from a differential cover, a non-moving but very important part of a far more complex component.

Great for my JK wrangler . A few tips, don’t fill to the upper fill plug. Fill to the lower fill plug , cap it off as just a squirt or 2 extra and that’s it. Filling to the top plug forces it out of the breather (learned the hard way) . It does clear rough country suspension components including dual steering dampener. Used with lube locker gasket and no complaints. My only thing was I opted to buy one “used” and it appears someone attempted to put it on scuffing the finish. The first time it rained I noticed rust so I will have to put some touch up paint on it but that’s what I get for trying to save $20.

Style: Dana 44 JK & Others
Overall, combined with the yukon gasket cover this is a huge upgrade to the stock covers. THIIIIIIICK metal with recessed bolts, easy to access magnetic drain and multiple fill plugs. Within a week of install I was able to "test" the front on a few chunky trails. The finish held up well and shown minimal signs of scratching. *** the only reason I cant give it a 5/5 rating is because the rear cover has a teeny-tiny slow leak and I think it needs some thread tape to seal up. My first picture shows how much buildup it gets after sitting overnight. after 4-5 days of being parked in the same spot it will make a single drip spot on the concrete. For the price, I feel this shouldnt come up. And yes, I did retighten by hand days later. But it so slow, I wont worry about it.I'm confident ill break an axle and have it off before I need to top off new fluid.*****

I am not a mechanic and have only recently started servicing my own Jeep. Changing the differential fluid was recommended by the dealership, along with other maintenance. I was quoted a total price that was stupidly high, so I decided to look into doing it myself. Thank you YouTube for your videos on shock absorbers, brake rotors and pads, cold air intakes, tire selection, rock rails and differentials. I am still not a mechanic, but I do have bragging rights. From what I read and watched, there is an engineering advantage to specific designs of differential covers. The more internal seams and bars, the less the fluid can naturally circulate with gear movement. There are also advantages to having drain/fill plus located strategically. The Yukon Dana44 has a smooth internal design, and has two drain ports; one at the bottom of the cover that you can't really see in pictures, and the bottom of two ports on the front (you see them both in all pictures). So there are total of three magnetized drain plugs. I also bought the Yukon Dana30 for the front and it did not have the drain on the bottom, so each cover has its own unique design. The cover is mighty thick and strong as hell. I wanted to update the covers from stock for 4 reasons: (1) I was cleaning the gears and replacing oil anyhow after far too many miles w/o servicing (2) I was concerned that the OEM cover could catch a rock and the lip roll back, spilling differential oil (3) The Amazon price was lower than anywhere else and I wanted to buy at that price (4) It is a badass upgrade It is true that there were no instructions for torquing the bolts, but I am not subtracting stars. Nor am I subtracting for the PIA of tightening two particular recessed bolts that were blocked by a track arm. Would have been easier to get to them with a ratcheting wrench, but the recessed hex bolts do have their obvious advantage. I paired the two Yukon covers with Lube lockers as opposed to RTV for gasket seals, so I used the torque settings of the Lube Lockers as recommended by others. I like the idea of colored cover that really catches the eye, and there are several awesome options, but I didn't think the extra $$$ was really worthwhile. The Yukon Dana44 cover was more expensive than some others, but significantly less than many others too. For the price, I got all of the engineering upgrades of the more expensive products, but paid less. In my book, that qualifies as a good deal. Hope this review helps you enjoy an off-road adventure.
