There are a lot of comments about how much more difficult this is on an old rusty shaft. That is true, a rusty old shaft will be more difficult, but the overall process is the same. I just wanted to demonstrate how we do it, in the shop, with new parts. Once you understand the concept you can apply the same concept to almost anything. When making the video we didn't have any crusty old shafts laying around so I worked with what we had on hand. I promise, we use the same basic procedures on older shafts too. When it comes to replacing joints in a shaft that is decades old and badly rusted there is a paradox. If the shaft is in that bad of shape it is probably not worth salvaging anyway. If your drive shaft is so rusty that you can't get the joints out using the procedures shown in this video, or this video 4xshaft.com/blogs/general-tech-info-articles/diy-u-joint-replacement, it is usually best to replace the shaft entirely. If the joints are so stuck that you have to use a torch, or have to hit the yokes as hard as you can with a heavy hammer, you will be further damaging the yokes in the process. The yokes are important, precision machined parts, if they are damaged, distorted, or extremely rusty, they need to be abandoned and replaced.
After watching this video a couple years ago I ended up using this yoke hammer method on my jeep u joints. I have replaced probably 5 or more jeep joints in this manner. Well, my daily driver needed a new joint and the truck is getting pretty rusty. I thought to myself there's no way these are coming out... I'll be dammed if I didn't see those joints start moving on my 2nd hit. This is on an old wisconsin winter GMC Yukon with 175,000 miles. Thank you Shawn!
@@Stoph345 Thank you. There are a lot of naysayers in the comments saying that this won't work in a rusty shaft but I don't think many or any of them have actually tried it.
it does look easy perhaps is a NEW U-Join the one you are showing us. The ones I remove are rusty and hard as a rock and in some cases, I have to use the touch for a couple minutes before removing it. but thank you for showing us.
As soon as you start thinking your gonna need to change u joints, get in there and soak everything with oil, i use the HF oiler can. Repeat every day. Capillary action and time works wonders I like to hammer on it and cause damage, done it many times
All u-joints can absolutely be replaced, even the staked units. You don't need to spend hundred of dollars buying/replacing the entire shaft, just a lot of elbow grease and new u-joints. You just need to press them out.
No, they cannot. You could grind out the stakes and remove the old joint but there would be no way to install the new joint. There are no snap ring grooves the yoke on a staked joint. Maybe you can make a video showing how to do it, prove me wrong.
You sure can! We did another video where I show the process in my garage, no special tools. I actually have only very basic, kind of crappy quality, tools at home and only used those tools in that video, found here ruclips.net/video/iBFchnrsz-c/видео.html&lc=UgzbbMjBtqHb2EwFlit4AaABAg
You make it look easy. After wrestling with them and using a vise to press them in, I finally got them installed. I try to use your method but the drive shaft from a 58 Chev wouldn't go together any other way.
I had an 'old rusty shaft' that his procedure didn't work on. Tried torching it, penetrant oil, smacking it every which way, air hammer, etc. with no luck. I couldn't just buy a new shaft - because they don't make them anymore for a 34 year old car. I eventually put it on the press. I didn't put it on the press to begin with because whatever geniuses designed this shaft made the ends round and tapered with no way to squarely and safely place it on the press. I eventually managed to rig something up using various sized square steel bars bent into half circles as a mounting surface and break it free. It took _8 tons_ of force. Then I had to do it 2 more times. Having completely restored a car, this is one job I would _never_ do again. I'd pay someone else to deal with it.
I’m over here like I hope I’m not ruining anything, using cloths over my vice, cursing myself for dropping things lightly. Then this guy is like, “I do it all with a hammer 😂” pow! Bam! Bang! Well now I feel a lot better. 👍
As a mechanic I've been researching on how to better properly put ujoint together and have come across several videos saying not to use a hammer and use just a press only to put the u joint together because the shock from the hammer can cause brinelling. My question is what is truly better? Is it fine to use a hammer or better to use a press to prevent brinelling?
In my opinion using a hammer is fine. This is for two reasons. 1 is that we're using a relatively small hammer and not hitting things very hard. If you have to hit the joint so hard to cause damage to the joint there is something wrong that needs to be addressed. 2 is that the force applied to the bearing cap and joint is axial, not radial. I think that brinelling is most likely to occur with hard radial forces. Although radial force is also the direction of force these joints are designed to transmit so I don't think we can do too much to them with a small hammer that the several thousand pounds of vehicle and a couple hundred foot pounds of torque won't do.
An issue im facing whenever doing ujoints up here in the rust belt is that no matter how careful I am on the disassembly, somehow the replacement joint is too wide to get the clips in properly. On severely rusted shafts I will cut out the trunnion and push the caps into the center so as to not break the grooves. Ive resorted to grinding a wee bit of the caps down, I don't like doing this but I have no choice. Is this the fault of cheap aftermarket joints or am I bending the yokes without realizing it? Been struggling with this issue for a long time.
We are general because this is a general demonstration. Most automobiles that use universal joints in the drive shafts use Spicer style joints. There are different size joints but the installation process is basically the same for all/most of them. This specific example is a 1310 series. This basic shaft (in varying lengths) would cover almost every Jeep ever made, many older ford trucks and SUVs, many older Chevy trucks and SUVs, international scouts, and aftermarket shafts for many Toyotas, Land Rovers, and more.
How is it that I struggle to do this with a 40 ton press and you make it look easy with a hammer my daughter got for her 3rd birthday. Clearly, I need more practice.
Nope, you are wrong. These are 1310 series joints, the most common size used in American vehicles for decades. The concept applies to larger shafts such as 1350 or 1410 series. This isn't how you'd change the joints in a dump truck or semi truck but most people don't need a demonstration on how to change joints in industrial equipment and vehicles.
What the heck kind of magic are you doing there? Hitting the yoke makes the cap come out?? That's a great tip, however it's also a brand new install, yes?.
It is brand new parts in the video which sometimes makes it easier but also sometimes makes it harder because new parts often fit more tightly than older worn parts. When we filmed this we didn't plan very far ahead and didn't have any old rusty stuff lying around for demonstration. We also have another video that shows more of an at home DIY process, with a used shaft.
@@glynnpowell7864 No duh. We didn't have any old junk shafts lying around when filming this so we used what we used. But the process we use is the same for old rusty shafts as well.
It's not that easy when you're changing out u-joints that have be in the vehicle for 100K miles or more. That's why most of here is to see how that is done. New parts go together easy.
Slimey automakers stake u joints. They dont want guys buying u joints they want to sell you the whole shaft. Nothing some needle nose locking pliers and heat cant fix though!
I get a kick out of these you tubers try that in the real world where the drive shaft has rust dirt and anything else that gets on them in real world use. I bet it would take more then a hammer too get it off.
That he has done this more than a couple times he’s really good at it! But a rum dum like me hasn’t! I need Shawn to realize whom his audience is!

Thanks for the feedback Mark. This video is mostly just to show how we do the install at our shop, the ideal way to do it if you have the equipment, with the understanding that most people are not going to be able to follow the same process at home. As I mentioned in the beginning of the video there is another video (I actually said there'd be two more, but we decided to just make one more) where we show how to do the job at home with more basic tools.

Its also alot easier when your using brand new, show us how to do it when their really stuck
I cant believe how hard I made this simple task with my technique... Anyways my life is easier because of this video. Thank you!
Showing the double cardan assembly helps me a lot, thanks
Very useful information, you can tell you have been doing that for a long time you made it look easy!
Wow this is awesome! I have a boat v-drive with a u-joint in an impossible position and I tried your method and it worked perfect. Thank you
Come up to Minnesota and try to tap the yoke like that to get the caps out…. Lol. Not a chance! Good video tho! 👍
It seems like Shawn has done this a couple times... :) Looking forward to getting my new DS for my Jeep Wrangler! Cheers!
Look at this cat, flipping his toys around like he's shaking up a cocktail. 🍸🥳

I was wondering if I can tackle this same job without the use of any type of press? Great video by the way, very straight forward. Thanks for sharing!

I’ve never had a cup move with this hammer technique….I just use a vice and a socket to sort them all out. No hammer needed, no damage or burrs.
Since watching this video I have yet to find a cup that won't move using that method. Also working with jeeps that don't get driven in salt though.
Wow, never seen a u-joint done with ease like this. Thanks for the tips! Can tell you have done a few thousand haha
This is much easier than pressing them out, thankyou

@@tomwoodscustomdriveshafts thank you for the great information and answering my question. I very much appreciate it!!
How many ft lbs would a press use without damaging the bearings? I remember hearing a click once and at least one bearing broke in half.
An issue im facing whenever doing ujoints up here in the rust belt is that no matter how careful I am on the disassembly, somehow the replacement joint is too wide to get the clips in properly. On severely rusted shafts I will cut out the trunnion and push the caps into the center so as to not break the grooves.

Ha. The way he is whipping things around it reminds me of Tom Cruise in that bartender movie.
Thanks for mentioning the bushing/thrust spacer. I doubled one up and had to pull and reinstall 6 caps. Frustrating.
I wish you guys would be specific on your title. What vehicle is this shaft from? There are different types of unjoints.

Would’ve liked to seen inside snap ring U joints were the caps have to be pushed from the inside out
Awesome video! I Thanx!
Does this work on a 20 year old drive shaft
Great info.
I was about to fuckup.some ujoints😅
Yea, try this with a rusty old driveshaft and see how well that's works lol
How is it that I struggle to do this with a 40 ton press and you make it look easy with a hammer my daughter got for her 3rd birthday. Clearly, I need more practice.
There's 0 rust on his
Yeah I agree. What am I doing wrong?!?!?
Damn pro speeds
Damn bro you would be a good bartender!
Than why the fuch is every u-joint iTouch damn near impossible to get apart I got to put heat on it soak it for 3 months and still use a press..
That’s normal mate….hammering doesn’t work in the real world. I use a vice and a socket, that works well.
brillaint
Show it when the parts replacing are rusted and old... Just a glimpse...
Yeah these are little mini you joints on a trail machine, you’re not gonna be holding a full-size driveshaft out of a truck or car like that
