I covered a lot in this video so here are some timestamps in case you’re in a hurry: - Spun Crank Hub Explanation: 2:13 - S55 Crank Hub Fix: 3:54 - Crank Hub Failure Caught on Video: 8:43

The additional images and videos while explaining are awesome

Literally just purchased my first BMW today, a 2015 Alpine White M3 w/the 6-spd manual. This bad girl has 47k miles & is in immaculate condition. I love shifting thru the gears in this beast already, the shifter is like buttah, that's a compliment. My sales dude straight up told me about this design problem(he owns an M4) but your vid really laid it out in great detail. I'm going to practice smooth, deliberate shifting for a while before getting "raw" with her & pushing the limits. Man, this engine is just amazing! Just wants to pull & pull! Great vid.

Super interesting video; I appreciate the conciseness as well! That footage was heart wrenching even with the heads up, lol.

Amazing video. I am looking at getting an M4, so its great having this information. Thanks!

Great video Omar if you are running stock your crank hub should be okay very rare to fail but if you are going big BHP hub fix is essential S55 is a great engine very underrated sorry to hear about your friends BMW hope it gets fixed soon 😎😎

Been watching your videos for months now and had no clue I knew you until I heard to mention Gabe. I'm Augy's brother. Great Content! Congrats on the new M4.

I don't think it's as widespread as many think. VANOS issue was "common" on the E46 M3, and supposedly BMW fixed it (faulty bolts) for 2005 and 2006 models, and my own 2006 still blew up at 64K. Even so, I never met any other E46 M3 owners that had that issue. Still, I am leaning towards the F80 M3 right now and if I end up in one I will do this "fix" first, only because it's crazy how easy it is to get more power out of that motor!

Basically, avoid kickdowns at all cost and be sure to be in the correct gear for racing. This ensures that your torque delivery will be smoother rather than praying on a kickdown. The 2018 and up M3/M4’s have proven to be better in terms of not spinning the crank hub due to harmonic dampening that BMW utilizes. I’ve been on a 100 octane tune for almost a year with 40,000 miles on my 2018 and thank God I’ve had no issues.

When he spun his crank hub did he happen to bend any valves or anything like that? Did just the new upgraded hub fix it?

Great, super informative video.

Good job 👍🏼👍🏼

If I just want the GTS Start Up Roar and Burbles and I get catless downpipes would I have to worry about this too much? I am not a crazy power head I just want it to sound good.

@Simply Car Things I just bought M4(non comp) with 28.000km, on how much i must replace crank hub i don’t want to tuned my car.?

Do you know if the crank bolt was still tight after spining the crank hub

Great video my man! I was always a bit nervous about that when I owned my old f80. I think I'll go with the Vargas fix if I ever get another s55

I am about to install a jb4 on my competition package 2020 m4 but I am scared. I will be running stock just with stage 2 and 93 octane. 3500 miles on car. Burger said the comps have higher flow exhaust and stage 2 is good to go as long as 93 octane is used on stock ZCP exhaust. Do you think I should do it or am I making a mistake? I won’t run e85 or race gas ever more than likely.

That was a great video thanks for putting it together.

“Aww fuckkk” 😂😂😂😂 1 like = 1 prayer for blues clues to be ready by next weekend 🙏

I've only ever seen this on two cars, both were mis-shifted and mechanically over-revved. Both had a new hub installed and running again in a couple days. I'm have a suspicion BMW engineered the hub like this on purpose to try to prevent valve to piston contact in the event of a mechanical over rev.

Great video

Have a buddy who works for BMW and he was pretty insistent that it isn't as bad as the internet has made it out to be. My local BMW dealers have seen zero spun hubs to date. So I'm not sure what to believe. No issues on my M3 with mods and it gets driven. Just avoid those money shifts and the kick down function on DCT's.

1 and a half year working at BMW workshop, 3 crank hub repairs was done in my time

Great intuitive video explaining the S55 crank hub issue. I have a 2016 F80 M3 Dct with a Bootmod3 tune and contemplating the vargas spline lock. What is the pricing for the fix? I was told 4000$ for Maximum PSI to do this fix which I believe is pricey for a preemptive measure. Albeit I dont run my car as much as Blues Clues and I only have 35k on the vehicle. With my low miles and the new G80 awd S58 coming out I would rather trade the F80 in on the new G80 M3 if the crank hub fix is as pricey as the cost of buying a used economy car. I was wondering what happened to Blues Clues. Cant wait for him to put out more content on the f80.

How many hours does the book say is needed to change it

The German that designed the hub was fired, demoted and then sent to the Eastern front.

I have a 2020 m4 competition. I was given a jb4. I installed it and then removed it within 200 miles after. I wasn’t comfortable running anything besides stock. I have it away to a fellow m4 owner. I want to enjoy my car and not worry all the time. Also I didn’t like what the jb4 did to my power band. The stock competition tune is amazing, this changed it in a way I didn’t like. I was doing a pull on map 5 and got a misfire at the higher rpms and removed the jb4 that night. Stock and happy again.

So should i worry about this issue if i am going to be stock?

Isn't this like less than 1 in 1000 cars or something? There's so much hyperbole on the internet. Very few actual reported cars with this problem imo.

Hey does anyone knows if the 2020 still has that problem

Hey did the car re start after??

Hey there, what were the two companies you said in the video for the fixes? The echo made it hard to understand.

Just picked up a m4 with 80000 miles on the clock. It's a stage one running around 500bhp.is this something I should expect to happen real soon anynting else I should watch out for Full service history with a year warrantt

Do you know any good shops in Texas that may do this fix?

Important to add that new B58 and S58 engines does have integrated crank hub's

When I hear that this problem can happen on standard engine but some high powered tuned engines have lasted a long time it make me think its more down to the people driving the car rather than a massive problem with the crank hub design. How many of these actually fail as a percentage of cars made? Is it really the problem that it's made out to be?

I've wondered if BMW changed the way the car come on the power back in 2016 to lesson this, they said it was about driveability, because the pre-2015 BMW software the boost came on much stronger lower down. When I got the car back from the dealer after that software update I thought they had detuned it! BTW I'm sure there are OEM friction discs between the sprockets on the stock hub and it is debatable that keying the hub just adds another stress point. If you are going to do it a spline sounds the best solution.

Great video, very informative, good job on this. However the percentage of spun crank hub is very very small and some companies that offer the fix have their dedicated army of trolls spreading false info on the forums all over about this. It's like cancer you may get it at some point or you will never have it. Just treat your car with mechanical sympathy and everything will be ok. No money shifts for manuals, for DCTs keep your setting in the middle ( i smoke Hellcats on my stage 2 tune with DCT set to 2 bars) , do not overuse stupid lunch control etc. I can beat anyone who uses lunch control with just good old fashion acceleration fashion. Lunch Control is POS as well as Kick down. If you have that mechanical feeling for your car you can feel that most aggressive DCT setting is not really healthy as well as kickdown. There are cars who are very heavily tuned and have over 90k miles on and have no problems. I use Stage 2 91 tune even though i have very good 93 octane gas available just to be safe ( i had subaru STI before my M4 lol). In the case of serious knock event i bet the crank hub can spin or when something is going on with oil pump etc. Do not panic drive your car hard but with mechanical sympathy. If you don't have it ..... well you will need to pay the price, but the chances are slim. This is the best video explaining the problem. Thank you Simply Car Things!

do we know what markets this hub part was installed in? in other words, has this part been installed in all s55 engines, or just the North American market?

The S58 and B58 also have the timing chain on the back of the engines. Every post 2007 bmw inline 6 turbo engine has this problem from what I read.

Was it and up shift or down shift cause it sounds like he shifted up not down

I just bought a 2020 M2C. Is there a technical/safety recall on this problem? It appears to be costly and can lead to an accident if it fails and the engine seizes.

Would the 2017-18 models be less susceptible to a crank hub issue without a tune as well?

What’s the cost to upgrade the crankhub

Dude my F80 barely has 8k miles 😳 I need to drive it more. Thanks for this cool video

When it spun, did he use the paddle shifters or the kick down when you quickly stomp on the gas pedal ? Or did he over rev and up shift at a very high rpm? Can’t really tell what’s going on in the video

Are the N55 M2 Engines at risk for a crank hub failure when running 4 to 500 BHP?

Is there any way of knowing the crank shaft has been upgraded from previous owner or prior?

Did blues clues go with the Vargas or the maximum psi hub?

I now this is an old video but I am looking to purchase a S55 engine car (M3 or M4) - How do I go about checking if the crank hub is about to give out? will a BMW tuner shop be able to take a look? or most likely they will have to take the engine apart for it to check? How much does it cost to upgrade the Crank Hub?

How can i tell if the crank hub was done on my s55 f82 ??? Po said it was done but no proof ?!

Thanks! I'm very interested is the rate of failure in a stock setup when driven hard.

how much did it cost to get the crankhub fixed

2019 m2c with 17k miles ready to go stage 2. Should I upgrade my crank hub? Thinking +120-150hp. I read that after 2016 bmw fixed the issue but i cant find more info

S55 is one of my fav engines so much tech

the reason I brought amg gla45. happy with that .cam chain sproket spinning on the shaft . bad design.

Great video man! The S55 is a solid engine but like all great engines they have their weak links.

So whats the new part do differently than original..?? Spoke too soon. Thnx

goin on the BMWCCA forums, you never hear of this outside seriously modded cars pushing way more horsepower than stock. I feel save with my M2C which is de-tuned compared with the M3/M4.

Some misinformation here. Not related to power but abrupt changes in engine rpm. More hp does not put extra load on the cam train (theoretically it does because cyl pressure is increasing).

Maybe a stupid question, but can you just weld the whole thing together?

Are there any cases of stock/non-tuned s55 spinning crank hubs?

Whats the cost for crank hub replacement?

Did BMW ever address the issue? About to get a 2020 M4

So is this a problem if you tuned it or can it also happen without being tuned

Do we have a percentage of f8x cars affected yet? Is this more prevalent than rod bearing failure on e9x M3's?

I’ve been pushing 600whp (e85 custom tune and Bolton’s) with stock crank hub for 20k miles with no issues. My car is a manual. I don’t overrev the engine or make “money shifts”.

how bad was the engine damage on the m3 video you experienced? fixable or new engine?

This crank hub does not particularly fail on stock bmws. I have not seen it fail, I use to work for bmw for 15 years and never seen the hub spin out like that. The only issue I have seen was when the serpentine belt gets shredded into the front crank seal and gets inside the crankcase! I actually took the crank hub out and as long as you properly torque the hub, it won’t spin.

It has like 100 radiators ! Love the s55

What do you know about the VTT Spline lock i want to get mine done but don’t want to pay so much is it reliable?

Sucks to hear what a great engine the s55 is at the same time “ don’t push it too hard” my car is stock and to hear it happens on stock cars really upsetting

8:43 Crank Hub Spins RIP

Widespread? Wow, how many have they sold and how many have failed?

Estimated cost of replacing the hub? (Prior to failure and damages)

The hub looks the same as the N54 and they really do not suffer from spun crank hubs with high boost. Why?

And never had a e85 tune , due to the aggressive timing advance needed to extract the extra power.... 100 octane is as far as I go

I’ve done a poll on this on M3 cutters and searched F80 forums. I’ve found 22 cases of it worldwide. That’s a 0.05% chance of it happening. It’s so so rare. It is mainly caused due to the stalling of engine on gear change (I used S2 logic). Also for some reason BM3 are 75% of them 22 cases. Stick to a good tuner not plug and play boxes for me!

💙💛💚🧡 Hey, I am thinking of buying a 2016 M3 by the end of this year, how much would it cost to get this Crank Hub done? (im in australia btw) Also, how would I know if it needs replacing? Are there any other issues I need to watch out for, or can do pre-emptive stuff at a mechanic shop? Thanks, Im a big car noobie. Appreciate the help 💙💛💚🧡

How is this not a recall?

Stage 2 VF tune, full bolt ons and exhaust....CSF intercooler....no issues 76,000miles

I’ve had my f80 for a year now second owner it has 80,000km no tune would it have gone by now?

is it common with n55 also?

I ask in number of bmw work shops in europe and only one said they seen this issue in highly modified m3 with over 600hp. Its so rare that when you've got stock car i wouldn't bother , and even with modified car is worth to take a risk imo.

do the crank hubs fail on stock engines?

Cool👍🏻

Does it apply to DCTs aswell

That sucks... I still want a F82 after the E92 335i hits 700whp, crank hub fix will be the first mod lol

Going stage 2+ with MHD next week and I am absolutely terrified of this happening haha

IVe been looking into an f82 but this crank hub issues is making me think twice of a future purchase .. 😢 Is this considered a Recall ?

I heard kickdown causes the crank hub failure

heavily tuned M3, 100k miles, what can possibly go wrong?

What exactly did your bluesclues friend have to do to fix his spun crank hub? Would you mind providing specifics?

Yeah definitely needs to be addressed just like the faulty charge pipes on our cars.. not that that really compares though even though it's the most common issue with f22s that I've found.. charpe pipe is such a simple fix compared to a crank hub

I can't fathom why it was designed like that.

Thank god we have the n55 That one is pretty much trouble free I always say its best to leave it stock. And take good care of it offcourse

Can the crank hub spin at idle?

Please correct me if I'm wrong but I think there is a much cheaper solution to this, there is a lock that you can put on and it protects the hub from spinning. And I think it cost only 100-150$.

I never heard of this happening in the N54, and it's pretty much the same design, not sure what's so hard to maCHINE A FKN gUIDE PIN!! BMW!!!

Great vid thx!! Also, get some better wheels for your sexy car
