Hollow kingpins break constantly. The reason is the hollow metal kingpin is not strong enough to support skateboarding . The kingpins are made of a harder steel than the aluminum baseplate. When a hollow kingpin breaks inside a baseplate it can deform and lodge itself inside the baseplate because it's a harder metal and can push the aluminum aside.
If you have a hollow kingpin that is broken inside the baseplate I will replace the truck for FREE. Just pay to ship the truck to me. I need these trucks for research and for future videos.
Steps to remove a broken kingpin:
1. File around the broken edge of the kingpin bolt.
2. On hard ground, hammer the kingpin down until the head of the bolt is hitting the ground.
3. On grass or soft ground, hammer the kingpin out the rest of the way using your new kingpin on top of the broken one. The soft ground allows the kingpin to come out of the bottom of the baseplate.
4. Push the new kingpin into place. Line up the splines of the bolt and with the grooves in the baseplate. When you push the kingpin bolt in, slightly turn the bolt until it lines up with the splines. You should be able to feel them connect.
5. Put the socket over the kingpin bolt. It's important that the kingpin be able to go all the way inside the socket as the kingpin gets hammered into the baseplate. If the socket is not long enough, the bolt will not go in all the way.
6. You can use duct tape to hold parts in place.
7. On hard ground, place the socket end on the ground. Use another socket or kingpin and place it on the head of the kingpin. Start hammering on the socket to push the kingpin bolt inside the baseplate. This requires some very hard hammering to get the kingpin in all the way. Use a piece of duct tape the socket and the ground for some traction to help keep the socket from sliding.

"Take the new kingpin to hammer out the old kingpin. And then order another new kingpin and use that as new kingpin for your trucks."
Soft bushing make it easier to turn but have slower rebound. Rebound is how quickly your board will come back to center. Hard bushing have a reverse effect. Tall bushing have quicker rebound because there is more mass deflecting/pushing. Short bushings have less mass so they are easier to compress but have less push/deflection.
Awesome. So glad these all worked great for you. We have been working on another project. Hopefully we'll be able to post new videos this summer.
For the most part all bushings fit every truck, with the exception for some longboard specific truck bushings. Longboard/downhill trucks have barrel bushings that are little tall for street trucks.
12 years ago and today, it help me out with a kingpin from a friend truck, thanks a lot
I have not tried to get it out yet, but with the help of your video, I will try. I'll keep you posted if and when I get it out of the baseplate
Thanks man. Replaced one snapped & one almost snapped kingpin by doing exactly what you said. (New style kingpin) No truck damage at all and two new, better quality kinpins inserted securely.
i've been doing this for a decade and there some really helpful tips! thanks man! keep it up!
Hopefully you got your new kingpin in place after a decade?
thanks for this. last my homie broke my kingpin a while back but they're my favorite trucks so i held onto them. now im glad i did
What ever happened to this guy? I use to watch this guy 4 years ago ...
WTF AGAIN
life
Richard keith omg
WhoCares is he still alive?
why is it sooo easy for you!!!!!! last time i needed to replace a kingpin this would have helped dooo much!!
That is an issue that has puzzled skaters for decades. Some manufacturers have tried to fix this problem with new designs, while some have not. If only the nut is sticking out you can get softer bushings and tighten the nut down, and still have the same turning ability. See if that helps. If it's the actual kingpin bold you can try to file it down. The bolt tends to stick out because it is a harder metal to grind away than the aluminum truck hanger/axle.
brreeedddaaaa... you made my whole life easier with this video...the duck tape metal tube thing literally just helped me fixed my truck...THHHAAANNNKKKK YOOOUUUUU!!!!!!!!!!!!!!!!!!!!!!!!!
Helpful vid thanks. Wear ear plugs when you're hammering. It really is loud enough to cause hearing damage
Thanks alot again, had this problem before and could not remember how to get it out. Using another kingpin to get it out was just cake compared to what I was trying to do.
I got your message about them being cruiser trucks. This is normal for your trucks. If you want looser trucks without having the kingpin fall off, get softer bushings. This way you can have the loose feel, and tighten the kingpin nut down.
We've done some testing that has not been released yet. In our opinion and testing Bones bushings are not good. Their recovery time was low. This is how quickly they can compress and return back to their original shape.
Find yourself some "vice grips". These are pliers that lock tight. They really help to loosen stripped nuts. If you're in the US you can find some for about 5 bucks. Definitely an awesome tool to have for lots of other things. Lots of people have then so ask around.
Your instructions are a little hard to read, but I think I know what you are talking about. This is interesting. I'll give this a shot.
@archzurfer The reason for grass is that the ground still provides resistance to hammer hard, and still allows the kingpin to come out completely into the ground/grass. There is a chance the carpet might work depending on the truck and how long the broken kingpin is. I doubt it. Two 2x4s can do the job too. See how I was talking about the old hexagon kingpins and hammering those in. You can hammer the kingpin out that way. You can lay the 2x4's flat, instead of how they are seen in the video.
If you freeze your new kingpin overnight sometimes you can press it in without hammering and when it warms to room temp it will expand and lock in place. Tolerances aren't very exact in the skateboard world so some might require some hammering but it will still be easier the colder you can get the pin. I'm aware cold makes metal brittle but the temperatures in your freezer won't be extreme enough to damage your kingpin, especially since you won't have to hammer the shit out of it to get it in your baseplate.
Smart idea!
Add some pressure behind the nut, as if you are prying it off. As you do that try to turn the nut. If that doesn't work you need to inspect the kingpin. Try to tighten the nut back down. You may need to file a thread or two no the nut as a correct path of threads to come off.
thx dude this was ace help i just bent my king pin ,so i need to know all this ,cheers pal .konny
Great video, I just broke the kingpin of one of my trucks, and I need to replace it. ¿Where can I get those sockets you used and what size should i buy 'em?
¡Thanks again dude, those vids helped me out a lot!
thanks a lot man,that was really helpful for me
Colors represent different durometers/hardness of bushings. There is not a select color that represents a certain durometer, so each brand uses a different color for each durometer. For example, a red bushing that is 90a for one brand might be red and 85a for another brand.
No mechanical damage at all. It's just friction from the truck rubbing on the bushings. It can be pretty annoying. We are currently working on this video.
Yes it will fit. Pretty much all street trucks use the same size.
You probably need to get a new nut. It could be the threads inside the nut or on the kingpin. The nylon (plastic) inside the nut is used to apply pressure on the kingpin. This is how the nut stays on without unscrewing by itself. The nylon may be worn out and is not longer helping to keep the nut on. See if getting a new nut helps. Your local shop should have one for you. You can also try using a nut from an old truck if you have one.
149's are a little too big for an 8 inch board. Better to go with 139. The rule of thumb is to not have the axle sticking off the edge of the deck. Sorry for the very late reply.
I wish I was like best friends with this guy so he could fix every problem I have with my skateboards:D
@K3V1NKR3W-Since the kingpin is broken inside use a new kingpin to hammer it out as I showed. Start hammering on grass instead of a hard surface if it's flying after you hit it. If on a hard surface that might be why it's flying. A cause might be the angle that you are hammering causing the bolt to bend. You could have a rare problem where there is a damage inside the baseplate, where a piece is jammed. You could hammer the stuck piece in and then try out. It might loosen, let me know if works
@ClowninAroun You can lay the board down and push down on both trucks to one side and feel if they are even. You don't need them to be even. A lot of people like their back truck tighter. It makes the board more stable for landing tricks, and let's the front truck do most of the turning.
If it is stuck do to rust, this will be the only case where we will recommend using WD-40. If it caused by damaged threads then you need to tighten the trucks and try to remove any debris in the threads, or fix the threads as much as possible using a file perhaps, and then try to remove the nut.
Wow im new here. Thank you for sharing 👍
just curious what bushings do you recomend? ive noticed many people use bones. I love your videos btw. keep it up man
Great video, it helped me out a bunch!
Not sure exactly what is happening without seeing it. You could use a magnet to putt it out. You may need softer bushing if you like your trucks super loose. You got to keep that nut on. You may also need a new nut that doesn't come off so easily. Let us know if that helps or not. We can look further into the problem if this didn't help.
Yes you can rethread it if you have a die. We doubt you have a 3/8ths die. So it may be cheaper to just get a new kingpin. As stated in the video, removing a kingpin can be done but it can also be tough. What brand truck do you have with a titanium kingpin?
the nearest skate shop from me is pretty far, but i guess it's worth it. Thanks for your help.
This just happened to one of my boards the other day. My dumbass didn't give it a good look before buying some new trucks but now that I realized it was just the kingpin that snapped. I plan on fixing them. Thanks for the vid
I think you're right. I was thinking Dustin Dollin too, but I wasn't sure if they were pro models.
He said kingpin 473 times
+Adam Devic 473 is a masonic symbol of the illuminati. Everyone knows that. Duh!
+Rat Vision - Skateboard Tech haha lol
It's a video about kingpins genius
Yeah he said it so many times irs like the video could be about them
Ok I'm here. Sorry for the late reply. Yes, you should be able to take your kingpin out. They can be very difficult to take out and put back in though.
Thanks for the vid. It worked perfectly and i can go skate again. :)
Thank you, it is very useful
Thank you mate !!!
Hammering actually was way easier to do. I tried this method and although it was working at first it got way harder as I screwed the nut more. It may have worked for trucks you got, but certainly not for the truck I had. Regardless, if it works for you that's awesome.
Kingpins snap at random times, it was already fractured before it broke doing a flat ground trick. Were you able to get the kingpin out?
If you didn't live in Indonesia I would have you send it to us. These kingpins pose a lot of problems and are extremely difficult to remove. You may need to actually replace the truck if you can't find the right person with a lot of muscle strength to hammer really hard to get it out.
thanks for the reply :)
yeah, it's hollow. hasn't broken and won't budge from it's original position
I'm not sure how you cut the kingpin, but it's probably not budging because of a tiny piece of the metal. You'll need to hammer it back in, file around the end of the kingpin and any damaged area, and then try to hammer it back out. Buy harder bushings so you don't have issues with the washer flipping.
@fmskates You had an axle break off? Any chance you still have that truck? This truck was not actually mine. I needed an old truck with a broken kingpin, so I picked one up at the local shop. It actually had a crack in the center of the baseplate too.
Yes, thats ok, as long as the trucks allow you to do it. What trucks does he have?
Try your local shop. If they don't have them you can get them online. Try your local shop because they may have old trucks lying around and you can take the pivot cups from them.
I have independents. its ok. thanks for taking the time to reply :)
What trucks do you have? Is it just wiggling in place while it is all the way in?
Vice grips. This is the best tool for clamping onto stripped nuts so you can turn it.
@comptonkillacpt Yes, but hallow kingpins can be even harder to remove because the broken end in the base plate can deform and wedge itself in the baseplate.
@TheSignatureK Only one truck? If you don't have a pair it's probably not worth keeping. You could use some of the parts such as the kingpin, nuts, washers, and bushings.
@csaw12 You can use a small socket. As long as you are hammering straight on the old kingpin you should be fine. I've never ruined a new king when hammering out an old one.
There could be a couple problems happening. If you have a hollow kingpin then I can go into that later. If the kingpin did not break inside the baseplate, and you were able to hammer it down enough before the end goes inside, then there is probably a tiny piece of metal not letting it go down. You'll need to hammer the kingpin back in, file around the broken end and then it should be easy to hammer it out. Or you may need someone with bigger muscles (seriously). It can be really hard to get out
That's awesome!
Did it break while trying to remove the kingpin, or while putting in a new kingpin?
Awesome, thanks for this.
Impressive!
Your local skate shop or online. Street trucks for the most part all use the same size.
Will my trucks break easier if I replace the normal kingpin with a hollow kingpin from the thunder trucks hollow kingpin replacement kit? ( have thunder lights)
Fuck it I'm buying new trucks
They are really all made the same. The shapes play a big part, but that's too much info for a reply. We have a detailed video coming out in the near future about bushings. Right now just choose the right durometer you like. We are in the middle of testing and don't want to recommend a bushing at the moment until we know what the best are. If you want to know a little more send us a message.
We have been asked this question a few times and it seems very odd. It usually ends up being that the person has cheap trucks. What brand do you have?
Pivot cups are not something that a shop usually has available, because the trucks are usually replaced before a new pivot cup is needed. However, with downhill/longboards pivot cups usually need to be replaced before new trucks are purchased. A skate shop usually has old trucks floating around where they can take a pivot cup out of and give it to you. You can find them on the internet of course. There are 2 sizes. All street trucks use Small (5/8" Outer Diameter), or downhill Large (3/4" OD).
@Scottde420 In the video the white parts are bushings. Since you are new to skating you should know that colors are different hardnesses and not just for looks.
@skateboardtech yea, i stuck the kingpin in the socket before attempting to install and it fit in all the way with a bit extra space
Most trucks now use bolts that are pressed in and have splines.A bolt at a tire store or even a hardware store will most likely not work. What kind of kingpin do you have?
I broke my thunder trucks a week ago sadly I discovered it has that hollow kingping and those lines at the bottom. I can't release that part from the base even when I hammer it, suggestion will be great for me
What brand of trucks do you have? This isn't right, but when the trucks are tighten more it may keep the kingpin from moving more.
It's probably normal for the trucks you have. What trucks do you have?
They are a little hard to find. You can try your local shop and see if you can take one out of some old trucks they might have.
@eVerProductions1 Maybe the problem is the socket. Did you make sure the socket is long enough for the kingpin to go inside far enough? The pingpin can only go in as deep as the socket.
I can't really remember. That was a while ago. Yeah they were awesome, because they were like the classic Vans but better looking. I haven't seen these since.
YOU ARE A LIFE SAVERRRRRRR
see i thought i needed some new bushings what do you recomend the trucks are thunders 145 highs i always ride high
@skateboardtech btw, have you guys considered making trick tip videos? I think you guys would do an awesome job
What trucks do you have? You may have to take the truck off the deck and tighten the kingpin from the other side too.
No necessarily. It should be solid, but when you tighten everything down it should be a lot better. What trucks do you have?
@TheGrantorino72 This is an increasing problem with Thunder's, or any brand, that have a hallow kingpins. I need to do a video on this. The problem is that the kingpin is hallow to begin with. It's not as strong as a solid one. The baseplate aluminum is softer than the steel kingpin. When the king breaks the ends become wider lodging themselves inside. Think of flattening a tube. That's what happened. So they are near impossible to get out. If u are young have someone older try to get it out.
I snapped my thunder hollow light kingpin, was only 5months old. Going back to ventures for sure.
@andersonjesse97 -- I've pretty much done the same thing. If you ride your trucks really tight it's easier for the kingpin to break, because too much stress/force is being applied to it. Over time the metal weakens and gets fractures, and just doing a simple trick like a shuvit, or even hitting a crack, will snap the kingpin off.
@skateboardtech hey man, I got a question, what's the difference between a hard bushing and a soft bushing and how do each affect performance of a board? I've been looking into replacing my bushings in my trucks, but I wasn't sure which to go with because I don't know what the difference is between them lol. Anyway, I thought I'd ask you because you're very knowledgeable about this kinda thing
@xXz0mbieXx14 Did you watch the video? You may need someone with more muscle to hammer it out. Is the kingpin hollow?
Sweet dude, thanks, i'll try this out... and thanks to me so quickly :-)
You need to press down really hard to get a hold of the nut so you can turn it. Try using vice grips too. After you get it off use harder bushings instead of tightening the nut down so hard.
@Mattdaskater69 You can try hammering it out. If you have 3/8th die you can use that to rethread the kingpin. If you are not going to reuse the kingpin use a file to fix the bad area.
It's making a hole because it is not in all the way. Did you notice this when you took the truck off? What trucks do you have?
Is the bolt itself perhaps rotating too as you try to turn the nut? This is odd.
Local shop, or online
If you have a broken hollow truck we may be interested in acquiring it. We could break one, but we want to see how everything looks from normal wear. You must live in the US too.
The obvious answer is the bolts aren't strong enough to handle skateboarding. It can be the truck geometry that causes too much stress, and really tight trucks or hard bushings that cause too much stress as well, and the kingpin breaks.
I would have recommended partly assembling the truck and tightening the nut to pull the king pin through, little mechanics trick for replacing camshafts and such.
