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.
How sad to see so many ignorant fools today who have mutilated large portions of their body through tattoos and piercings, thus marring the image of God they were created in. These are not true ladies and gentlemen of moral character, but pathetic followers of the latest perverted fads.
Sounds nice until support after isn't there. After the last retube mine is worse than ever and was told to pound sand by Tom Woods. Can mark the driveline turning clocked in any orientation and tune is off center causing mine. Tom woods part I paid for but was told to pound sand.
Hi Kyle, Shawn Wood here. I looked up the records on this to try and gain some insight as to what you are upset about and here's what I can find. We lengthened and re-balanced a shaft for you in Dec 2023 then you called in April 2024 where you and I had a 1 minute and 15 second conversation. I don't remember the details of that conversation I may have said that I don't know how else to fix the problem or I may have explained that a double cardan shaft with a slip yoke style transfer case can result in high speed vibrations. I can guarantee that I did not tell you to "pound sand". At any rate, I'm sorry that we weren't able to help you and hope you were able to find the solution you were looking for somewhere else.
@@tomwoodscustomdriveshafts7159 I informed you it is substantially worse than before. As shown in this video it clearly falls into the Dynamic vibration category. I understand that this style is less than ideal however no SYE'S are made for the Ford T-Cases so unfortunately is what it is in that regard. You did not specifically say pound sand but stated we checked it it said it was good so we don't need to check it again. When it's a dynamic issue. The bigger frustration is I have clocked it all over on T-Case splines as well as all 4 locations on diff flange and it is 100% the same so still leading towards a driveshaft issue. I placed a dial indicator and measured the run-out near pinion and T-Case and the whole tube top to bottom is not centered. I even ran it and marked it and it's clear where the tube is not centered. Have videos showing this etc. That's the reason I am frustrated. Vibration starts at 2,300rpm shaft speed and gets bad at 2,500rpm and remains bad to and past 3,000rpm. That is shaft speed not engine RPM. Gets a hair better under load and on deceleration. Worse when no load which again points towards a shaft balance concern. That's the frustration.
@@tomwoodscustomdriveshafts7159 Angle at T-case is 13* and pinion is down 1.6* and is leaf sprung so under load should minimize to near 0 under operating conditions. Shaft length from center of u joint to center of CV is 35 1/4" so its nkt a super short shaft. Angle does suggest a double cardon should be best however with this style of slip on T-Case maybe a standard style driveline with substantially less rotating weight would be better. I belive the current one which is a 3" tube, 1350s is 27lbs. Which is a lot of weight to be spinning at 3,000-3,500rpm.
I have a vibration at 1800 rpm and only occurs at this particular point. Any thoughts what could be causing this? Thx
Harmonics probably. Everything in the vehicle that is moving is vibrating, just at varying intensities and frequencies. At certain points multiple parts of the system will all synchronize which will increase the perceived intensity.

thats what she said
How do you purge the slip yome
It would be nice if they could use a true constant velocity joint on drive shafts. The problem though is protecting the rubber boot that seals the CV joint so dirt does not get into the lubricating grease. Easy to do amongst the front or rear suspension members but hard out in the open where a traditional drive shaft is used.
VERY informative video. Thanks for this one. 👍
Ok great so I have a 1993 wrangler and I put new standard leaf springs on front and rear and it did lift the jeep some. So how do I account for that do I still need a SYE? I did notice the angle did change some because of the new stock suspension.
brillaint
Thankyou for sererating the 2 sources of vibration 1/ angle imbalance vs 2/ actual weighted imbalance
I need like a basics before these basics, video lol.... Anyone know where one of those is?? Or a book or something?!!

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.
2024 LEXUS GS350 FSPORT AWD...BEEN SHAKING LIKE HELL AT LOW SPEEDS, HIGH SPEEDS, INTERMITTENT, AND MOSTLY WITH SOMEONE IN THE PASSENGER SEAT. MANY PARTS REPLACED, NO HELP. NEXT ITEM TO HAVE INSPECTED AND REPLACED, REAR DRIVE SHAFT. ANYONE HAD THIS ISSUE, AND SOLVED IT?
I got a rwd 2008 is350 so it’s a single shaft but at a stop or when coming to a stop u can hear and feel a slight vibration under the car fucking annoying as soon as I step on the car it goes away and the car drives fine
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
Highway driving..2deg just sayin
Or run a CV joint !
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
Great information presented well, I would be happy for you to work on my vehicle anytime. Thank You.
The press machine is cheating but I guess faster...
Show it when the parts replacing are rusted and old... Just a glimpse...
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. 👍
Come up to Minnesota and try to tap the yoke like that to get the caps out…. Lol. Not a chance! Good video tho! 👍
Great video and excellent information! Thank you!
This is much easier than pressing them out, thankyou
Thanks, Shawn.
Great info here!
I need to get a CV Yoke for my 1979 Jeep CJ5 and don't see one available on the website. Any help would be appreciated. Great video explaining how the double cardan helps the issue. Would you recommend wedges or rewelding perches on axles?
Great info. I was about to fuckup.some ujoints😅
This vid helped me a lot to find out what the .... happend yesterday at my Ford Capri. The unbalanced drive shaft test reproduced excactly the noise i heard under my tunnel (at 2300rpm machine revs). It stopped immediately when i hit the clutch and my speed dropped from 160km/h to 100km/h. At normal speed, nothing noticeable. Thanks a lot. 👍
Thank you!!!
I plan on going to a 6.5” lift from IRO, do I need to have a custom length drive shaft? Like I gotta measure? Please reply thank you!
Yes, you will need to measure for a custom length shaft.
I put new u joints on my rear drive shaft because I had to take the transmission and transfer case out. Now I notice that at 75+ there is a vibration feeling. I tried my best to mark the drive shaft but because this was my first time I think some of the components are not longer in the correct position. I also don't know if those new u joints are good because they felt kinda tight even out of the box.
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.
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.
Great video! I wish you spoke about when cars are lowered as I am dealing with a horrible high speed vibration which I am wracking my brain over. I am guessing the two piece driveshaft is too flat and shortening the length too much and binding. Love to know your thoughts.
Wow, never seen a u-joint done with ease like this. Thanks for the tips! Can tell you have done a few thousand haha
Curious what the effect is on oiling for the pinion bearing when you raise it higher.
It doesn't affect it. The ring gear centrifuges the oil through the entire differential housing with enough velocity that it can easily get where it needs to go. This can be seen around 4:00 in this video th-cam.com/video/3XgpmBR-3Fc/w-d-xo.htmlsi=DRalClvDvclmzavK&t=208
Excellent!
Have you ever seen rust throw a driveshaft out of balance?
No, the rust shouldn't affect the balance but what the rust indicates about the shaft probably does. A rusty shaft is an old shaft and an old shaft almost certainly has worn, loose, and distorted parts, all of which will affect the balance.
Thanks! Very helpful. Got a mystery pulsing/rhythmic vibration above 40mph in the rear. Narrowed down to either CV, differential, wheel bearing, or drive shaft. Mechanic thinks driveshaft. Your video really helped me understand why it could be driveshaft.
95 Camaro z28 80mph vib. Every body has a different solution. Q. did it vibrate off the show room floor at 80mph. I doubt it. In fact, that issue would have been on blast in 93 and either killed the car line or Chevy would have recalled the car due to safety. Let's accept its not the driveline and aluminum DL won't really fix it. Somebody said change pinion angle to + 1.5 ... NOW we are getting somewhere. What changes things at 80 mph? Weight on the car. Rear suspension mounting wear?
I wouldn't jump to the conclusion that the shaft didn't vibrate off the show room floor. It is not uncommon for vehicle to have these sort of problems when new. It won't be every single car or truck but there are certain vehicles that are prone to drive shaft vibrations, even when new. However, lets assume that it was smooth in 1995 when the car was new. Here's what has changed since then, 29 years have passed. That means that if your shaft is a stock shaft it has 29 years of wear on it. Worn out parts will cause the shaft to wiggle around slightly, run off center, and cause high speed vibrations. The thing that changes at 80 mph is the centrifugal force of any imbalances in the drive shaft. These forces quadruple when the speed doubles. Because centrifugal forces are a product of mass x speed, reducing the mass with an aluminum shaft should actually improve the situation quite significantly. I don't think your vibrations are angle related, I think that they are dynamic vibrations. More about all of this here 4xshaft.com/blogs/general-tech-info-articles/diagnosing-drive-shaft-vibrations
I swapped out my dana 30 for a dana 44 in my XJ and I cant get the pinion angle very high without killing the caster.... where can I find information about how to address this? Do you have videos? Thanks, this video was helpful but not so much for the front :)
It's sort of explained after around 14:30 when talking about a multiple double cardan shaft. In the video I mention a Grand Cherokee specifically but the concept is the same for an XJ. More information about this type of shaft can be found here 4xshaft.com/products/zj-or-wj-multiple-double-cardan-front-shaft?_pos=1&_sid=db61262f4&_ss=r. Again, this says it is for a Grand Cherokee but also build these for XJ Cherokees.
@@tomwoodscustomdriveshafts7159 ok great!! I'll go check out your website because I can not get the pinion angle high at all and maintain any caster,..... do you think a double cardan driveshaft would help me?
Well, this answered all my questions. Thanks for the great, informative video. All the information one needs, and nothing more. 👍
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.
Excellent, thank you.
Now THIS is a good video. This can really help people dealing with those issues. Great work
This may sound dubious but Sir, let's assume we live in an ideal world, would running a cv joint with zero drive angle last longer than a cv joint with some degree of drive angle. Thank you so much for your time and answer.
Yes, the less angle things are running at the longer they will last. And the more angle something runs at the faster it will wear out. There is something to be said about grease circulation at zero angle though. If there is zero angle the grease won't circulate around the parts as it should. However, this might be a bit of a paradox because if there is zero movement in the joints there is not really a need for grease in the first place.
Outstanding video. Watched this video the day after I installed an SYE into my XJ and still learned a few things.
