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?
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 czcams.com/video/3XgpmBR-3Fc/video.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.
Fantastic video thank you.
Shawn WOOD, relation? Nice AK tattoo😁
Damn bro you would be a good bartender!
Great video and info. Knew when i saw tom woods it would be good
Wish you just went step by step like you where ordering one yourself Step 1 Step 2 and actually write measurements Not you can start hear or there
I had a vibration for year's. Checked everything mathematically, changed shims, ect. Turns out the shop that did my SYE didn't tighten the front yoke all the way. GRS noticed it during a inspection. Once tightened , no more vibration.
Great video. Instead of a double cardan at both ends, why not just do a shaft with true CVs at both ends? This would be less weight and a lot more tolerant of angle mismatch on lifted vehicles. LR defender front shaft has that 15 or so degree offset front and rear uj setup on splined shaft from the factory to counter the factory angle mismatch. Given it is full-time 4wd and defenders sometimes lifted, wouldn't true CVs be a best of all worlds solution?
Most lifted vehicles have angles too severe for a CV joint. Stock Jeep JKs come with rzeppa style cv joints in the stock shafts. But for the lifted jeeps, even Dana/Spicer, who makes the stock shafts for Jeep, switches to a double cardan design. The double cardan handles more angle better without failing. More on that here czcams.com/video/IEfoy_OjUUM/video.htmlsi=t_qhBQroMTIqDXv3
@@tomwoodscustomdriveshafts7159 I see the jk has design limitations but there are so many fwd front axle CV joints and they are designed to work at large angles. Is there some fundamental wear vulnerability running the CV design constantly at an angle vs uj design? I wonder how would the CVs hold up on a Toyota Corolla if you drove it at a large steering angle constantly for 100,000+ miles..
@@pwatom22 It's not just the JK that has limitations, that is just an easy and common example. There are a couple reasons cv joints work better on axles. One is angle, most cv axles are not running at a lot of continuous angle. They might see 20 degrees during a turn but most of our driving is relatively straight. The other is speed. The drive shaft is turning 4-5 x faster than the axle shafts. This also means 4-5 x rotations more per mile driven. Assuming angles are the same, a cv axle would have to be driven 400,000-500,000 miles at around 200 mph for it to be subjected to the same speeds and duty cycle as a drive shaft that averages 100,000 miles at around 50 mph. If you factor in the angle, you'd have to drive that corolla in a tight circle turn for those 400-500K miles at 200 mph. When it comes to friction or the deterioration of the rubber boot on the cv, the more times you bend it back and forth and the faster you do that, the faster things wear out. Another reason is simply practicality. For most of the vehicles we deal with a double cardan yoke on the transfer case is readily available and easy to achieve. I can't say the same about rzeppa style cv flanges. When it comes to custom aftermarket shafts for modified vehicles the u-joint double cardan shaft is much easier to achieve.
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
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.
Hello! Thanks for the informative video. We'll done! I just bought a 2005 f150 and its perfect at high speeds, but taking off while turning, like out of a driveway, when taking off there is like a shuttering that comes from the rear end. Does that sound like driveshaft/u-joint to you. Thanks so much
If it is drive shaft related it sounds like it is an angle issue. Normally turning shouldn't affect drive shaft issues but perhaps there is more resistance, therefor more load on the shaft, when you are turning. Angle related drive shaft shudders are usually worse under load. Could be something else entirely though.
I never knew the story of how you built the business, but I prolly ordered my first driveshaft around 1999, I was working at a shop in MI called Jeeperz Creeperz and he suggested you. Pretty cool, keep up the good work!
Thanks for the comment. I remember Jeeperz Creeperz!
awesome video, very detailed, now i know what i need to do, thank you
Thanks for the comment! I'm glad to hear that it helped.
Super awesome! I didn't know I was this interested in this topic. You must be a good teacher. Thank you
Thanks for the kind words!
