*Who knew a mini-series about freaking diff covers could be so engrossing? Thanks Banks!*
Me too.
I was thinking the same thing.
Lol and I’m not laughing at you
hell i can't wait for the last episode myself.. something tells me.. he's gonna design a cover and price it to recover some of the cost of this research.. which is a lot.
I really want to know what the Best Aftermarket cover is the best for my 2004 F250. The suspense is killing me already...
As a mechanic, I can honestly say I have never wondered whats going on behind a diff cover. But, happy I came across this video!
You're a mechanic and you don't know how a diff works?
@@NittoNba44 he lied
@@NittoNba44 pretty sure OP is referring to the fluid
I wondered why the outside axle bearing in my LSC went bad. Now I get to chose between too much and too little. BTW pain in the ass to change. Traction lock.
Hello can i ask is there really that much fluid on every diff?
Maximum respect due Gale Banks. Not just to make everything he touches faster, but to understand how and then make it available to the public, he deserves a medal ( to go with the coin ).
Respects to the poor guy in the truck while up in the air.
These covers are a ripoff. Go ahead, make him richer. DA
I feel I went from 0 to 10 on learning and understanding what's going on under those diff covers and I've never considered myself mechanically inclined. Great teaching!
What a legend. Still waking up every day wanting to improve and learn. He's such an inspiration. I would give anything to be that devoted to a cause. At that point, it isn't work anymore.
You must have taken lots of grammar classes.
Sometimes it's our perception of our very own definition of work that we choose not to agree with.
I'm with ya.
ACTUALLY HE WAKES UP SCHEMING ON NEW WAYS TO SEPARATE FUCKING FOOLS FROM THEIR MONEY -- REMEMBER ,BUSINESS MAN EQUALS THIEF !!!
A hobby gives much of the same nourishment.
Jane Book you are a moron.
Who else needs to change rear differential fluid??
I do it every 100,000 miles.
Not me I just bought me a new RAM! Lol
I do it once a year in the front and rear axles of my truck. Might seem too frequent, but it gives me a chance to make sure the gears and bearings are okay, and to catch a problem early before it turns my axles into grenades. Also the T-case and transmission get new oil/filter.
I need a rear diff first, hahaha
I do it every 30k. Front and rear.
Who knew synthetic oil turns to milk coffee when spinning😂
Its actually yoohoo in there lol.
Anyone else get thirsty just now? Lol
Like laughing? #ScottyKilmerLaughing
And a latte when you blow a head gasket...
You supposed to add water.
@@jacobsebastien3910 but not too much. It'll tears weak. Lol
Just looking at Gale Banks and hearing him talk with such confidence makes one stop and say, "This guy really knows what he's talking about." Thank you for sharing Mr. Banks.
Name one gas/diesel aftermarket performance company that does as much R & D as this guy does.
That place with the 300mpg carburator
No one does! They definitely test everything and verify all results! My only beef with Banks is the Derringer for my truck isn’t released yet and you got yours way before me Joe! 😂👍
John DiMartino, isn't your truck fast enough??? Those 10 speeds haul ass!
Nobody even comes close. BUT All the big three light diesel U.S. truck manufacturers buy technology or parts from Banks, so is it really "aftermarket" ?
@@dickdanger7867 and the military
Mr. Banks, Thank you for investing in an open honest evaluation. Maybe this testing will lead to a Bank's diff cover that truly performs better than stock.
Stock performs perfectly. Thats the whole point of this video.
Wow Gale , I’m a retired CATERPILLAR mechanic. I just stumbled across your channel. This video should be required for all mechanics. I concentrated mostly on engines but did rebuild differentials and all other components. This was extremely interesting. Looks like It’s gonna be a binge night. I’m especially interested in the 2020 duramax series. I’m probably gonna buy one later this year. I’m a little Leary of the first years of major design changes though.
The actual R&D that Banks does and the know-how is just simply amazing.
I know this has been a large investment for your company for a product you don’t even sell. Just know you are really educating the industry. Please keep these kind of videos coming. It just strengthens your brand for honest quality products.
He sells Banks Covers now 2020/21
This man has forgotten more than I'll ever know.
+1. I'd say he's forgotten to forget more than I'll ever know.
That statement inspires very little confidence in everyone's abilities
@@WotchTheWerldBern
That was meant to show respect for Gale more being self deprecating
@@danmanthe9335 the phrase is overused, unoriginal and doesn't convey anything of value. It's more genuine to just offer someone thanks without sniffing their balls too. Just saying.
Yes it does. He is saying that he respects the tremendous knowledge Mr. Banks has gathered over his lifetime. If you continue to struggle to understand or make inferences, I'll try my best to help you out.

Notice how he said *former* ford ptu engineer.

Sounds like something a chevy owner would say
@@hilljackzack7284 🤣🤣👍
A man after my own heart. I work on industrial process and test instrumentation. Consistency and repeatability are the cornerstones of an excellent test (along with consistent test methodology)
I like when Mr Banks gets curious, cool stuff happens when he does.
Eric Brunhammer is your profile picture a Compaq computer from like 2005 lol
I have that computer. It's an Compaq
512MB of RAM. 20GB hard drive
Never thought I would find the inside of diffs so interesting - Be interested to see a strobe put on the turbulent areas to show the pattern better.
You can tell this man is passionate. Ty you for the information. I learned a lot
“I want the knowledge and there’s nowhere to find the knowledge” I feel that a lot
Everyone knows that diff covers with skulls work better.
Surprisingly for the Harley Davidson edition it doesn't come stock with that lmao
Add a pair of truck nuts on the back and she’ll be sick
Crying right now lollll
😂😂😂😂
uh yeah i had to go imediately check. and yes my money is going towards a skull cover... no odd shapes, "closely" matches factory shape, ring gear channel....check.... bullet proof...check.....cover cost...cough. knowing its money well spent priceless!
Wait... You mean the engineers with a lifetime of experience is smarter than an armchair mechanic!?
Ya!
No way not possible 😊
No, I know more than him
AZREDFERN mechanics can’t be smart?
@@Slowboi335xi he's talking about people who sit behind youtube talking as if they know everything about cars
I think I want a Cafe Latte after watching this
😄
The most under rated comment right here lol
Or have some taco bell lol
😆😆😆😆 te pasas!
It's a conspiracy.
Mr. Banks, I appreciate this video and your “test and prove” attitude. I feel I went from 0 to 10 on learning and understanding what's going on under those diff covers and I've never considered myself mechanically inclined. Great teaching!
Thank you so much for all these great educational videos .... hugely appreciated
I think whatever comes out of this we may learn where we can not lose a few horsepower here in there and what we can put on a rear axle to make sure that lives a long happy life especially for the lubricant. The coolest thing of all is he's not doing this to intentionally disparage anybody that makes diff covers he's just after the fax in the information where they lead us is where they lead us. Facts don't lie. Thank God no politics here in the video or the conversation
Gale Banks ! Thank you for this most informative class and video on where differential fluid goes ! I have been reading about your company for what - at least 40 years or more..
I am so grateful for all your hard work, and for your family sharing you with us over all this time.
I hope that you and yours will always be well..
I could watch Gale talk all day. I'm not an engineer or mechanic, rather just a guy who likes to turn the occasional wrench. Love Banks' style. Always impressive.
I cannot believe how much this caught my interest. I watched every second in awe. Can't wait for more research and details.
Would have been awesome to see the flow when it was in reverse gear :)
@Ray Man LOL
yeah really, obviously wouldn't wash the gears as well, this was a neat video
Dont usually go very fast in reverse. You??
@@hotrodray6802 Not *yet* I don't!
Thanks Gale for such a detailed experiment, I am hooked on this series and can't wait to see some data!
I just rebuilt my read end on my Chevy and was alot easier than it thought it would be! Of coarse I had some guidance from my ol Pops! He is 73 and we actually went to Bessemer State College for Auto Mechanics when i was 17 to 19 years old! U treasure those days!!!! Anyway have a blessed weekend!!!!!
As a visual learner, this video is a literal god send. I’ll never forget this awesome information!
Mr. Banks, great vid. Just had my 8.8 rebuilt recently, of course been looking up info. Your vid has been the best by far. I never subscribe to channels, yours will be the first.
First time seeing the dynamic lubrication, great study, thank you Banks!
Thanks for the time to make this vid, Gale is an absolute Legend!
Such an awesome video! I've been a huge fan of Gale since i was kid back when he was doing stuff with the 7.3 and 6.5 long before anyone else got in the diesel game That and the twin turbo chevy small blocks, Gale is a big part of why i got into automotive. I hope one day to be able to make it out that way and meet him. To be able to shake the hand of a true icon in our automotive world. Keep up the great work guys, your passion is what keeps this industry alive!
Mr. Banks has my most sincere admiration. He has been building amazing machines since I was getting started in the mechanic business in the mid 1970’s. Well done sir. I hope to meet you someday. I would like to know his oil and lube preferences and I’m sure a lot of people would also like to know! For both gasoline/turbo, and diesels! Keep up the stellar work! God bless!
Most rear axle vehicles I have to repair on the axle side including my own it's not all that simple but please let me explain, first it depends on the terrain the vehicle is used flat level roads it's all okay to have the correct level and all so if you do high enough speeds, but I do field repairs on farms that sometimes take me to spots that well is so hard to get that 15mph is speeding and have to be in low range 1st gear for several miles with sometimes sloped badly to one side and had previously a bearing failure on the higher side of the axle. Now I've learned that if you do any off roading with slopes that is to the side it's best to over fill axle but in this it creates another problem and that is with high speeds foaming is a problem so you have to sacrifice. But don't just run and overfill your axle just yet just because you're doing a 10 yard slope to the side at 10mph as there'll still be enough lubricant to protect your axle side shaft bearings. Hope you will find this helpful. Oh I've been a field mechanic for 26 years and just something I've picked up over the years.
Couldn't have asked to find a better and more knowledgeable channel during quarantine. Time to binge and learn stuff
Thanks Gale and crew at banks power, finally some clarity, insights and updates on this matter for 2021… for me what got me was keyword when doing testing and or data gathering is what Gale have said as well which is Repeatability and consistency And also eliminating factors that might affect the testing.
Gale you look like you are having a lot of fun! I bet you are already working on making a clear squared off cover, can't wait to see the result.
I'd love to see that too! Why do I see that being the next video?!
I was about comment this, we need plastic models of those aftermarket covers
This is a very remarkable demonstration. Great job. Thank you for sharing. ✌️
I love your approach. I love the straight talk. Keep it up, Gale!
It's once in a lifetime to be able to see action in the differential. Thank you Sir!
Very interesting test and a great video. We need more content like this on TH-cam
Make a plastic cover molded in the shape of the MagHytech one and let see the fluid results
with thin plastic sheet, the diff cover itself could be used as a vacuum mold.
I would like to see what happens to fluid when it hits what he calls a step and if it really matters. What I'd also like to see just taking a rear end and attaching an electric motor to it. That way you can measure current draw at a given rpm at the rear wheels and you can run it for longer periods. It would be interesting to see what happens to the fluid after running at 60 mph for an hour or longer. Does the fluid have more bubbles or the same?
@@brainfreeze44131 THAT WOULD F****** WORK! We had a bench in the USMC (it was a USAF hand-me-down) called the MA-3 bench that was used to test generators.
Again, good idea.
Having the truck on a dyno creates the similar load/friction (build heat like on the road).
I suppose you could disconnect the yoke from the driveshaft and then somehow tie in an electric motor to turn the yoke instead.
I pretty much assumed that would have been in this video.
Just installed my new banks diff cover. Looks great, works awesome. Thanks Gale!
I have been repairing cars for over 40days. This is the first time I ever seen what goes on behind a diff . Great vid
Thanks Ali! 🏁
I like the idea of aluminum for a differential cover to deplete the heat and keep the viscosity of the oil at a decent temperature! Can imagine how aluminum would work well when towing with a truck! Thank's for sharing!
Some Jeeps have the "heavy duty" version of their transfer case housings made of aluminum, which...I didn't fully understand the reasoning behind, until I watched this video.
It's not for strength in that case, but rather because it wicks away the heat better than steel.
Glad to know if I tilt my diff with shims, front bearing will be getting lubed no matter what angle. Thank You Sir.
I admire people who love to share their knowledge! Thank you Mr Banks.
Thanks for the video gale. It was really help ful. I hope your new diff cover design works well.
"You want to get the heat, the hell out" --- #LifeGoals
Spoken like a true prodigy. 👍🏻
@@bankspower What banks is forgetting here is that the gear oil level must be sufficiently high enough to lubricate the axle bearings pressed into the ends of the axle tubes as well as the carrier bearings pressed onto the diff carrier.
@@texasrox2010 Wow... it's like you were stoned during the entire video... so I'll summarize: when sitting still, you don't need any axle bearing lube, but when going just 15MPH, there's so much _turbulence_ and splashing, that the axle and carrier bearings GET PLENTY OF FRESH LUBE. Graphic videos of dramatic transparent diff covers aside, have YOU ever had a rear axle bearing seize with less than 150k miles on it?... No?... then it must be getting enough lube, Q.E.D.
TLDR: Mechanical Engineers know WAY more than you about proper lube levels.
@@texasrox2010 you dont know how a semi-floating axle functions. A full floating axle, like in a 3/4 or 1 ton uses the diff lube for the wheel bearing lube. The axle of a half ton does not, it is sealed at the edges of the pumpkin, and the wheel bearings are sealed roller bearings that do NOT receive lube from the pumpkin. Nice try though.
Imma watch the movie "Heat" now
Bloody brilliant and thank you so much for putting this here, the diff, always taken for granted. :)
Great video. The visible enthusiasm is cool to see in your work.
Thank you Mr Banks, you’ve probably forgotten more than I know about oil and transmissions. 👏👍
Stock seems to be best and aftermarket is bling! Thank You Mr.Banks
I always learn something whenever Gale speaks.
Kraj You are a fucktard. Be silent, child.
Wow!You could not have made a better video! I was gonna buy new covers,now just primer and paint👍,very informative...my eyes are opened.Thank you for taking the time to show us sir,Big thumbs up!👍👍
Thank you for watching! We learned a lot during our testing of the various covers.... enough to create some incredible innovations. You'll hear about them soon!
Thank you very much for taking the time and effort to make these videos Sir. We enjoy every one of them. Thank you for sharing your hard-earned knowledge
Thanks for the support. Gale wants to build a smarter automotive and diesel community. He feels that this is the best way.
I just love how he always wants to know, and if he cant find the data he just throws everything at it and he finds the data!!
Mr. Banks, I appreciate this video and your “test and prove” attitude. While I agree with you that the flat backed covers are a terrible design, one thing I suspect that might differ from what you are suggesting at 6:40 , is that maintaining an even gap between the ring gear and cover to in fact not be all that beneficial. From working with hydraulic systems, I suspect a reduction in clearance as the oil travels up the back of the cover and over the ring gear is more beneficial as it helps the oil column to maintain the velocity needed for the oil to achieve escape velocity and get thrown into the pinion gallery.
I've been wondering about this for over 10 years.... thank you
This is a Tremendous video...Thank you so much for making this! You really Know what you are doing!!!
Great series 👍🏼
But 20 dislikes ?! Must be aftermarket diff cover owners 🤭
LOL.
Nah probly some tree huggers. The diff companies are probably thanking him.
their dispersal pattern is inadequate!!! haw haw!
Daniel Minic Yea if i spent $300 on a worthless item id just bathe in my ignorance too
Good stuff Gale. I sure miss delivering material to you guys. Keep up the good work.
I always wondered.... and now I know. Thanks for the knowledge, Banks!
This is the first video iv watched an this channel off the bat is amazing great job ur a great mechanic especially to a young kid like myself that is wanting to learn all about how stuff like this works i really appreciate it youve done an amazing job thank you 👍👍👍👍 this channel could really change my life
Thank you for the kind words! Based on your comment, you'll really enjoy the other episodes in this series as well as Killing A Duramax and Building A Monster Truck Engine.
Interesting. Have done differential work and never thought about the way the gear oil is distributed.
Joelynn Carter as you could see, they became submerged dynamically via the ring gear carrying the oil there. While static, it drains out of the axle tubes.
thats pretty cool, i like seeing how the inside works in actual motion than an animated 3D video sketch
I dont know if you remember her but my grandmother worked for you out of Azusa from 95 to just about 2005. Her name was jane kusaka and its cool to think she worked for you and now im watching your videos, love everything you do.
Great video, I learned a lot and just ordered the Banks cover for my truck.
Really enjoying this dif cover series
Fascinating information. Thank you, Mr Banks!
Absolutely fascinating video. I and probably hundreds of thousands of car fanatics have never seen the inside of a diff in action. Now I know why diffs don't have to be filled to the top. One negative, the flashlight reflects and makes it difficult to see some facet of the diff action. Too bad there isn't another device with which to point to the innards. Thank you for making this video
Nice to see a well made video by a guy who knows what he's talking about. Thanks!
Great Job! Its Awesome that you guys actually moulded a factory reared cover . Thanks Banks !
I dont know why I'm watching this at 8 am. I don't even have a car... but it's interesting.
Dan knowledge is power
Amazing informative video. This has been a lifelong mystery for me. Thanks for making my day man serious.
thank you Banks Power. this video is really useful for my mechanics students who study English applied to machines. Your explanation is clear and very interesting for all of us, congratulations and i'm now your subscribed tech teacher!!
This is by far one of the coolest videos I've ever seen.👍 I really like to see how things work in real-world circumstances. Thank you so much and where do I get a plastic dif cover for my 02 Silverado. 😁
Awesome video... can't wait for the facts to come out. I love how you're going about it. awesome diff cover by the way. I can only imagine what the results are going to be like based off of what we saw in this video. I cant wait for the next video Thank you for taking the time money ect to do this testing. I'm sure it's been done by Engineers for automobile companies several times but they're not sharing the results and you are so again thank you.
Gale, I worked with Randy Ritchie many years ago at Foulger Ford. We had many discussions about your work re diesel performance. Great video on diff fluid flow. I always thought of diff housing as nothing more than a leak proof box.
This is amazing to get a lesson from a legend like Mr Banks I salute you sir
Great video and so much great information too 👍👍. Now we just need Banks to make an even better diff cover !
I am in the medical field and have many peer reviewed journal articles to my credit. This guy does studies correctly. Too bad many on TH-cam believe anything they see, I think this will show that looks don't equal performance.
Well, I'm a local dive barfly and have many peer-reviewed verbal rants to my credit as I often hold court at the bar and wax poetic about life in both philosophical and theoretical contexts and I thoroughly agree with you; this guy does studies correctly!
I'm not going to to believe what I see in your post unless you show me peer reviews of it. See how that works?
Gale Banks is a living legend. I've been impressed with his work since the 70s.
Differential cover heat dissipation and splash orientation is a must to protect the life of a hard working rear end.
I used to work at Nissan, and when people used the first generation Titan as a work truck and differentials started to drop like flies, all nissan did was to update the diff cover, what a difference!!!
excellent video...it is very interesting seeing the differential fluid & how it behaves....
Thank you once again, I follow things like this. Reducing the heat in the rear end is a really good thing. As anyone that works on vehicles knows heat is a killer of things if not controlled. Watching your videos has educated me in a different way. I understand the thoughts and theory of what you are explaining. I live in Alabama, summer time here is brutal on a rear differential. DoesUsing your differential cover have any drawbacks for the winter?
Oh, and the applications for racing!!! My mind is going in several different directions at once!
Always wanted to know how the RD works, great video
Love the knowledge and honesty he is sharing!
This is great. I always wondered what was going on in my Dana 44's.
I really like this guy...
So earnest and sincere.
Without the smooth transition of the cover, over long periods with a cover without that flow direction, one wonders if the lubricant would endure extra shearing forces? Not to mention foaming and the extra oxidation.This all perfectly illustrates what engineers and Spicer and Meritor told me about the way their covers were designed. Good work and I am dying to see the results.
Jim Allen I’m also interested in this test . I believe you meant aeration as opposed to oxidation in regards to the foaming of the oil. One is Air mixed with oil, as is the case here, vs a chemical change at the molecular level (oxidation). I believe anyway.
Alexander Coburg He is correct. Air contains oxygen. Oxidisation is caused by oxygen. Aeration of oil, especially with high temperature, accelerates oxidisation immensely.
Yes, foaming is the less correct term, but maybe more understandable to more people. Foaming and aeration, of course, are a major source of oxidation and early lubricant failure.
Great video! Really enjoyed watching and looking forward to the final results!
Stay tuned, we have the diff covers in production right now. Also, we will be posting a results video following the release announcement.
Thanks Gale for the great video.The plastic cover reminds me of the original Revell auto chassis kit with see thru V8 engine I got for a gift back in the early 1970's as I was a kid.Us kids that are now 55 or older should remember that model kit.
Once in the while I see them on Fleabay.
The rearend was see thru .I probably see the similar if I put oil in it and spin it .My mom would not be happy if it started to spit out on the dinning room table. LOL....
Wow this guy is a professional
This was oddly relaxing to watch.
Gale Banks is a man of absolute wisdom and knowledge. I really love that he has taken to this new age of free information to the public. He wants his product to help you help him help others. He also is known to admit when he is wrong publicly. So you won't have horrible customer service experience if something goes wrong if you programmed or installed correctly.
Sir, you are so well-spoken. Great video.
