The only issue that I will start by noting is that I had to go somewhere other than Amazon to buy mine because if I didn’t have bad luck with my purchases then I wouldn’t have any luck at all. But moving on, these bad boys are the most hardcore, high performance, high durability, great looking differential covers that money can buy! I originally bought a Rancho RockGear diff. cover but the only thing you’ll save on between the two options is weight, and that’s because the Rancho diff. cover is only as thick as a piece of construction paper. The Yukon covers are thick, durable, engineered perfectly, and built to last! I’ve now got less noise out of my axles and know that they’re protected on the trails. The fill holes are perfectly placed, nothing leaks as long as you use a new gasket during installation, and the magnetic plugs are an added feature that I truly love as well. They are pricey but if you take your rig anywhere that those covers might get hit, then it’s still going to be cheaper than buying a whole new diff!

This was installed on a 88 C-1500 truck. It’s well make so durability should be good, easy installation, the thickness is crazy and excellent value for your money and so far it has no leakage. Definitely recommend this item.

Okay, the Yukon diff cover is Solid. This should be said right up front. So, as I tell you what a pain in the back side it is to install, you'll know the juice is worth the squeeze. I have said it before and I'll say it again, I hate engineers. If you're the guy or gal that designed the original Dana 60 diff cover, please punch yourself in the face. You put 9/16ths bolts all the way around except the toughest one to get to and then you threw in a 5/16th allan screw. Said allen screw is rusty, full of dirt, and impossible to get a allan socket into. I fought with the original allan bolt for a good deal of time, but finally got it out. If it were just one more bolt life would have been easy.... however, I guess they felt there wasn't enough room for a bolt there. Now we're putting on the Yukon cover that has a fresh coat of silicone on it, but oh yeah, there's that same tight spot where there didn't want to put a bolt. Guess what? Yukon cover doesn't fit there any better than a bolt would have. I took a grinder to that part of the cover and thankfully it's pretty soft steel and ground away fairly quickly. I hit the exposed metal with some black paint and put the cover on, but holy smokes it's heavy. To be fair, I'm a little weak following a pretty severe motorcycle accident, but damn, it ain't easy to hold up there and get a bolt into it no matter who you are. I did get it in, so it's not impossible. Then... ya know how I was complaining above about the one 5/16ths allan? Well, that's all the way around on the Yukon. So, after a little bit of a tough time installing it, I am still glad I have it on there. The thing is a Beast!

I have a 1984 Chevy K10 that I upgraded the axles from 1/2 ton to the 3/4 ton using the axles from a 1980 K20 3/4 ton, and thanks to the review left by HAMMOND I was able to purchase this cover and adapt it to my K20 10 bolt front axle. I was in the same boat he was, as I had purchase the Yukon cover for my 14 bolt rear and loved the look. Searched for one to match for the front and they didn’t make a cover for my 10 bolt front. With his review I was also able to make both my axels match with this these awesome Yukon covers. Just had to shave a little bit off the passenger side, and drill/tap one 5/16 bolt. It wasn’t hard to do and looks great.

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.

Style: Dana 44 JK & Others
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.
