Build a Tough Differential Cover! (For a Watts Link [Or Not, Whatever]) Mighty Max Ep. 15

In preparation for the Watts Link, we build a custom differential cover for a 8.8 Ford Mustang axle! The center link of the Watt’s Link will be mounted to the cover, so it needs to be able withstand heavy lateral forces to keep the axle centered under hard cornering. Nine pieces of 3/16 inch plate are used to build a rigid turtle shell-like structure over the aluminum cover to protect the internal components from explosives, and keep the axle centered during some crazy trips to the grocery store.

Hey Everyone! I realized I neglected to show how this cover fits over the factory cover! By keeping the factory cover in place, it prevents excessive fluid turbulence, which keeps air out of the oil. I’ll be sure to include that in Part 2!! 🙌

I nearly added a fill port. I even purchased a threaded bung and plug. But when I went to measure the height of the fill in the factory, I realized it didn’t have one and then found out the Mustang axle fluid plugs are in the differential and not the cover! As for a sight gauge, that would be far too convenient for me. 😂 Thank you Mark! 🙌

[@FACEBOOKS-WBDS]

I wanted to do this for a long time but, stopped because the form of the cover is on purpose. Not just to be cheap it's formed to make the spray off the ring gear to be directed to the side bearings and axle tubes. At least on what i was working on (12 bolt chevy). Also the bolts are your next weak point, I would step them up a size or two and only use grade eight. it's no longer about clamping force but the bolts sheer value

[@GarageFab]

Agreed and agreed! I mentioned it early but neglected to show that this cover mounts over the factory cover. If this were my vehicle I would most certainly beef up the bolts. I drive like an idiot. I make jokes but my Wife drives like a sloth on sedatives. So I’ll be changing the bolts from those shown to some stronger bolts but keeping the size. In my opinion, 10 3/8” bolts would have a greater shear strength than the 9/16” bolt that attaches the Watts link bars.

[@garybuder4645]

Don't forget you will need a way to fill the diff with fluid

[@GarageFab]

That’s hilarious you brought that up, Gary! I cut the bung out of an old exhaust pipe for the fill hole threads, went to the auto parts store for a threaded diff plug to match, wrote the script instructing how to determine the height of the bung and recorded the audio. It wasn’t until I went to film the actual footage of doing the work that I realized that the factory Ford Mustang diff cover didn’t have a hole in it! I had to look up a KZbin video on how to fill the 8.8 differential with oil, and found that the fill hole is actually in the front near the drive shaft flange. So on this particular cover, I didn’t need a fill hole. But that’s still good to point out for those working on other axles! Thank you Gary! Cheers!

1/32” Polycarbonate , It’s Clear Allows holes to be located and Marked with Sharpie . Cut holes with uni- Bit or scissors You can join smaller pieces together with Aluminum tape . It is worth it Much better the 1/4” MDF The Make 1/4 Polycarbonate

[@tobygathergood4990]

Awesome cover. I'd like to say that I'm old enough and experienced enough so that I no longer make mistakes....I'd be lying. The reason stock diff covers follow the ring gear's shape, is to direct the oil to the bearings and the pinion bearing etc. with a minimum of work. Since your new diff cover, does not do this and is now standing away from the ring gear in a flat plane, the oil won't be directed to the places it is needed as it should be, it will be going all over the place inside the differential and not oiling the pinion bearing, the carrier bearings, the ring & pinion interface and even the out axel bearings correctly. You can't just add oil to the diff because that will promote foaming and develop more heat which will kill the oil's lube properties faster than stock. It will also affect your fuel mileage as the ring gears is now buried in oil, contributes to not only more heat, but fluid generated power loss. This will happen with any the flat backed diff cover you can buy aftermarket. One thing you still can do it weld in directional vanes inside the cover to make that problem go away. Rather a great deal more engineering needed. I am wondering why you didn't make the new cover from aluminium, I think you have a Tig...yes? Well that's my lecture for the day, I'm going for a beer.....well, I would if I had any.

[@GarageFab]

Ahhh, aluminum. One day. My machine is capable of steel TIG only. Aluminum TIG is certainly a skill I hope to acquire in the future. Maybe after a welder manufacturer discovers the channel and sends me a machine for free. I can’t see myself dumping that much money into a machine I’d rarely use. As for the diff cover, this one will be as good as the factory one. Because the factory one fits underneath. I saw a KZbin video several months back of various styles of covers made in acrylic so you could see the foaming oil inside. Very eye opening. I’m no engineer so I just have to depend on the knowledge of the original manufacturer. 🤷‍♂️

[@tobygathergood4990]

@@GarageFab I hope you are gifted with an AC/DC TiG as well, they're awesome machines. However, in the meantime you can flame weld aluminium, (if you have a torch and some small tips). I like the Henrob/Cobra torch I purchased many years ago. They are fantastic for fine work on aluminium.

I have seen flame welding in videos. They made it look easy but is that not one of those skills only the elite and most skilled craftsmen in the world? Also, until I’m no longer working out of my attached garage, I have a bit of a fear of torch setups.

[@Verticalpedalgarage]

Bad ass as usual brother. Are you going to weld the nut on the inside? It seems like the gear oil would eventually penetrate and leak.

[@GarageFab]

Thank you my man! Yes. Absolutely. The only nuts I have currently are Nylock nuts. Needless to say the Nylon doesn’t like the heat of the welding so when I need to weld a locking nut, I buy the all-metal type. Lastly on final install, I’ll be sealing the threads with sealant made for gear oil. It’s a low pressure component so the most I should ever see is a slight seepage. Hopefully not even that. 🤞

Very cool vid, presentation, humor, tech. Subscribed!! Personally I wouldn't be happy welding over an open axle / diff, it's at risk of having bb's dropping in.

[@GarageFab]

Thank you my friend! Glad to have you. I agree. There are several things on this build that haven’t received the amount of care I usual give. Typically I’d remove the internal components first. Instead this time I coated the gears with anti-spatter spray and went at it. As for the BBs, I intend to thoroughly flush the entire axle housing before final assembly. There is so much metal and aluminum oxide abrasive dust packed in there after the axle was shortened, a few weld beads are the least of my worries. 😂

@@GarageFab OK buddy, fair play. I guess its hard to cover all the details in a quick video but you've got them covered. Looking forward to more from you.

[@jayinmi3706]

So, just looking at it in the video, it makes me think that a watts link kind of functions the similarly to a reverse 4 link does (I think that's what they're called. where it has one set of arms going forward and one set going back).

Binge watching this channel as well! I'm trying to figure out c-notch/link suspension on 99 s10 that I'm I'm putting hydraulics on...I need the rear axle to "3 wheel" or pivot while also going up and down..any help would be appreciated. Love the videos man! please keep posting vids! Can't wait to see more! "Keep moving forward " bud!

[@GarageFab]

Thank you, Claudio! I haven’t had the opportunity to build a truck like that yet, but if I did I would definitely go with a triangulated 4 link. Maybe even a double triangulated 4 link. With heim joints on all the bar ends, you could get a crazy amount of travel and articulation with no panhard bar or watts link to limit you. If setup properly you could potentially get 24+ inches of lift and still be completely drivable. (Bonus tip: with a triangulated link setup you could theoretically remove the frame over the axle eliminating the need for a notch. Granted it would take some creative engineering to mount the bed and fuel tank but it’s possible. 🤔) Lemme know what I can assist with and I’ll try my best.

[@kevinholbrook7174]

You are doing absolutely awesome work! I have a project of my own. But, I am having trouble with a 4-Link suspension using the same rear end as you are working on. My theory is using the factory bushings on the top of the mustang rear end. My project is building a Special S-10. Any help is greatly appreciated. Thanks 🙏 and have a blessed day!

[@GarageFab]

Thank you, Kevin! First question, are you planning to do air suspension? I was considering the same thing. I changed my mind for a couple reasons. The factory Mustang bushings ended up being too far apart for the much narrower Mighty Max frame. I fear a similar issue with the S10. In order to get an adequate angle that would keep the axle stable under heavy cornering, the upper bars would have to be really short. That’s not a big deal if you’re building a static height vehicle. The Mustang upper arms are quite short. But short bars cause problems with adjustable suspension especially if you’ve got significant travel. The shorter the bars, the more front to back motion your axle will see and therefore could potentially pull your driveshaft out of the transmission. My second reason might not be as relevant to you… I wanted to build an axle truss and it was looking like the angled bushings we’re going to cause some issues. If you do decide to go that route, I recommend investing in some Spherical upper axle bushings to replace the rubber ones. They will allow for a lot more movement that would normally tear the rubber.

[@kevinholbrook7174]

@@GarageFab No, I was not planning on air or bagging it. I am planning on using coil over shocks and with a custom 4-Link suspension but without any upper wishbone! I was not planning on using short upper bars and they can be equal length. I do like the idea of what you did with the D-350 double bar watts link! With the idea of a custom 4-Link suspension I was planning on using the factory mounts as much as possible but if not so be it? I am also planning on maybe a 3” / 4” drop stance ride height as well too just enough for nice clean and cool stance. I like your rear cover for the 8.8 and I was wondering how much would you charge me for maybe making me a couple of them and for me to powder coating one of them chrome and the other one in color of my choice. lol Thanks 🙏 for replying back with the information! I know what I like when I see it but whenever it comes to the math and geometry of a 4-Link suspension I am lost?

[@GarageFab]

Sounds like you should be good then. Using factory mounts like the front leaf springs frame mounts is generally fine structurally for non air suspension. They hang down too low so they won’t allow you to lay frame but that won’t be important to you. The only possible effect to using those mounts is because they’re so low, it may cause your bars to angle down some which will could potentially cause you to lose some traction on acceleration. That also may not be of much importance to you if you don’t plan to race. As for the diff covers, since starting KZbin, I haven’t been taking on any custom work. I just don’t have the time for it. My apologies. Best of luck, Kevin! Feel free to ask questions as you go. 👊

Hold off until the next video! I mentioned it in the beginning but some folks pointed out that I didn’t make it clear; This cover mounts over the factory cover. The factory cover is formed in a way that keeps the oil from excessive turbulence and foaming. Changing the shape of the cover ruins that. Thank you my friend! 🙏
