Yukon Gear & AxleNodular Iron Differential Cover YHCC-D60

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

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.

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.

Don't know if they corrected it but the Ford 8.8 rear end cover I got from Yukon has both bolts. This thing is really bullet proof, expect some weight to be added over the stock rear end. I know there is a review saying they are missing one of the bolts but perhaps they had a defect or it was corrected since then. I don't work for Yukon and I'm not getting paid for the review - just letting everyone know as of 2021 the cover has both bolts. I showed a mechanic of mine the rear end and I will say we both thought it was pretty heavy/tough. I replaced the OEM diff because it was leaking and at 80,000 mi on a 1999 Ford E-150 it was about time to git er done! So changed out the OEM rear cover that had pin hole rust marks in 2021 with this and I'd have to say she's good to go till her next maintenance. The only thing was putting it on - as I indicated it was a little heavier :) and a little I mean a lot - then the OEM rear covers. So it took a little more to ensure the diff didn't move around when we put the bolts on. This is my second Yukon Diff and I was impressed with the one I put on my Suburban so I don't mind recommending it for the Ford as well. Both worked and looked great. Also you won't have to worry about pinhole rust holes where the diff will be leaking - this cover is extreme.

Perfect fit for 2004 Avalanche 2500 with seized and destroyed fill plugs. Overall I'm very happy with this cover. Nice thick steel, probably about 1/2" thick. Fasteners were high grade plated 12.9 hex cap screws with lock washers which recess below the cover lip. Both fill and drain plugs are beefy 3/8 tool hex plugs about 3/4" holes or so, very easy to upright a 32oz squirt bottle to fill the dif, no hose games. I emailed customer service at Yukon to ask a couple questions before I ordered and they promptly replied with the correct and helpful information. My complaints are the manufacturer website said it came with a gasket and it did not. Then the Yukon brand name plate was attached upside down which looked goofy under the truck. So I removed the name plate altogether. When I notified Yukon about the issues they failed to respond at all. Overall very good product, I would recommend it to others.
