Universal Joints - Part 7: Centering and Adjusting Axial Play
Рет қаралды 62,983
Күн бұрынWeber State University (WSU) - Automotive Technology Department - Transmission Lab. This is the seventh in a series of videos on universal joints, constant velocity joints, and driveshafts. In this episode, we learn how to properly center universal joints and adjust the axial play.
Timeline:
0:00 start
0:10 Introduction
0:48 Setting up a dial indicator to check the axial endplay
2:20 Measuring the axial endplay on the universal joint bearing cups in the aluminum driveshaft (0.0035") Out of specification of 0.0197"
3:51 Measuring the axial endplay on the universal joint bearing cups in the steel slip yoke (0.0015") Within the specification of 0.0197"
5:36 Axial endplay on driveshaft side after replacing the copper snap-rings with grey snap rings. (No change in the axial endplay of 0.0035".
6:50 Axial endplay on driveshaft side after replacing the grey snap-rings with pink snap rings. (0.0005") Within the specification of 0.0197"
7:20 Summary of specifications
8:46 What would happen with the aftermarket universal joint installed?
10:20 The "I changed the u-joint and now the vehicle vibrates" complaint
10:41 Universal joint centering is maintained with equal thickness snap rings
10:50 Universal joint axial play is adjusted with selectable thickness snap rings
11:22 Differences in factory service information for universal joint service
11:55 Wrap up
This video series helps partially cover the following NATEF Master Tasks:
3.D.1. Diagnose constant-velocity (CV) joint noise and vibration concerns; determine necessary action.
3.D.2. Diagnose universal joint noise and vibration concerns; perform necessary action.
3.D.4. Inspect, service, and replace shafts, yokes, boots, and universal/CV joints.
3.D.5. Check shaft balance and phasing; measure shaft runout; measure and adjust driveline angles.
3.E.4. Measure drive axle flange runout and shaft end play; determine necessary action.
Questions for teachers:
1. How much axial end play was measured on the slip yoke side with the coated black snap rings?
2. How much axial end play was measured on the driveshaft side with the copper-colored snap rings?
3. How much axial end play was measured on the driveshaft side with the grey colored snap rings?
4. How much axial end play was measured on the driveshaft side with the pink colored snap rings?
5. How does one center a universal joint in the ears of the driveshaft or yoke?
6. How does one adjust the axial end play of the universal joint in the ears of the driveshaft or yoke?
7. How much axial end play would the universal joint in the video have if the aftermarket universal joint on the comparison board was installed rather than the Spicer universal joint?
8. What can cause the "I changed the u-joint and now the vehicle vibrates" complaint?
9. How is driveshaft runout affected by universal joint axial endplay?

This is clearly the absolute proper method to remove/install Universal Joints. I have watched every " How to " video on KZfaq and with a clear conscience, would feel guilty if I followed any video other than these! My interpretation is that if one uses any other method, its a roll of the dice! You may have no problem at all or end up going down a rabbit hole trying to figure out what went wrong.....I am grateful for this series! THANK YOU for the in depth data, facts, analysis, undeniable procedure!

There is a serious lack of availability with snap rings in various thicknesses and the fact kits are only supplied with one size shows a SERIOUS PROBLEM with the industry. This is so bizarre that spicer are the only ones to supply several, and even at that they vary alot. whats needed is a vast assortment of .050" - .065" in .001" increments. This man John Kelley is worth his weight in gold, most people who claim to know alot about ujoints have never even heard of this stuff or what in the world axial play IS.

I did notice in this part 7 one small mistake. You mentioned that a 1330 series and a 1350 series has the same size cap and that they are just a different width. That is true for the 1310 to the 1330 series joints with a cap size of 1 1/16 and a compressed width of 3 7/32 for the 1310 and a 1 1/16 cap and 3 5/8 width for the 1330. The 1350 has a 1 3/16 cap and a 3 5/8 width.

Great video, I saw all 7 parts. It motivated me to do the work (driveshaft fix) in best shape. Regarding the centering of the shaft, u-joint and shaft cup holder, imagine yourself as a machinist and do the following: With dial indicator, 1) while the drive shaft removed, check the run-out of both transfer case and differential flange coaxially (mating surface) and diagonally (side way) 2) While rotating the drive shaft, measure the minimum reading of the dial indicator at the bearing cup outer surface (approximately at its center) for all of the four cups. This will give you an indication of how much the actual cross its self becoming off center from the real axes of the drive shaft. This can be complemented by using a micrometer to measure the thickness of the cup while the u-joint is disassembled. It is direct result from the assumption that the bearing surface (flat one in the cross) is a reference point and the cross has to form exactly a square shape otherwise the slow down and speed up movement will have variation on it. Also, this inspection will give you an idea about the flange yoke condition, if it bent, the variation between two facing cups become substantial. 3) from whatever runout we found across thee shaft, I think it can be reduced by playing with the different thickness snap ring to move the shaft across its axle (up, down, left or right) trying to compensated to whatever defect found in the drive shaft.

Thanks for this detailed series on U-joints. I just changed 2 U-joints on my 2000 Tundra and believe it or not I encountered the exact same problem. The Toyota new OEM non-greasable U-joint just didn't fit. It was a bit taller than the original part and the snap ring didn't fit. For me being the first timer using a Harbor freight ball joint tool I just scrached my head what I did wrong. In process while I was forcing the caps I broke on cap so I had to buy another one. Finally because I didn't have a thinner snap ring I went ahead and shaved down the copper coated snap ring until it did fit. I wished I saw this series before I tackled changing the U-joints on my double cardan drive shaft.

Nope. That ain't hapn'n. Not for a one-time use.

I now relate the operation of universal joints to helicopter rotor hubs with blades attached, in that there is a static balance or run out which determines if everything is balanced. Then a dynamic balance is accomplished to trim the cord angle of the blades about the hub or universal joint. I never saw the relationship before, wow. If there is a vibration of any kind after replacement, it shows quickly, unlike a car where a higher speed might start the vib.

@@WeberAuto I'm here to learn. The other day I installed Spicer universal joints in mom's 2004 Jeep Grand Cherokee rear driveshaft. They were the greasable type with the zerk on the cap. I cleaned the slight rust on the yoke with a small wire brush on a Dremel. Before installing anything I test fitted the snap rings. I had 3 copper, 3 green, 3 grey, and 1 odd one the accommodate the zerk. All 3 colors fit just fine. I searched and even called some tech at Spicer. All he said was the copper are the standard ones and those should be fine. Apparently the grey and green are thicker but I never got dimensions. I installed everything by using the copper (on a hunch). After everything was fully assembled everything felt slightly too tight. What was I supposed to do? The other options would have been tighter and more difficult to install if not impossible. I did find a video where someone file-fitted the snap rings to their liking. Is that ok? How would I know if it's tight due to the snap rings vs the yokes' own interference fit? I hope it'll wear into itself and center itself, but I'm afraid it'll fail prematurely. I intend to watch all 7 of your videos.... perhaps 1 per day. Could you point me towards which video would answer my concerns? And have you got any videos on correcting driveline angles? Thank you for reading this.

Vibration is gone, and I'm hoping that these U-joints are a quality brand. Do you know who makes the motorcraft joints for Ford?

John, Thank you for a super series; obviously a lot of very hard work and much dedication! I'm curious how much axial runout is normal between trunnion and bearing cap? Surely there must be some as you wouldn't want preload on needle bearings. Assuming there is some runout allowed, would this runout within horizontal trunnions/caps add to runout as you measure runout in the vertical?

I have your app on my phone and i have corrected several things and my vibes have been reduced and now I am down to a T2 vibration. I looked at my front axle driveshaft and it appears to me that there is considerable side play or "movement in the universal. It seems like the caps should be tighter--and they are held with internal C clips on the inside of the yoke. Are there different thickness C Clips available to improve "centering" of the yoke like there are on the INTERNAL (or E-clips) that go on the outside? Thanks John
@dangerdavefreestyle 2 жыл бұрын
Mr. Kelley, the reason why you did not see an initial change in the axial play from copper to gray at the 6:00 mark is because they did not exert enough force on the end caps to overcome their friction fit in the bores, this is why it takes a press to get them in or out. the pink ones obviously did the job, however i am not certain if you had any difficulty getting them in the grooves, or if you did any pressing when the footage was cut and the camera was momentarily off. you should be able to theoretically take the snap rings out, without the axial play being altered due to said friction fit of the ujoint bores. if you had too much axial play and went with thinner snap rings, youd have too much clearance the moment you assemble one side and would have to shift the ujoint in its bore to center it and take up that gap as well using a press, and the amount of force you initially exert onto the ujoint beyond what is needed when it butts up against (and is stopped by) the snap ring is initially what should give you your baseline axial play.

Hi John a brilliant and thoroughly researched series. Very informative, there was so much I didn't know! Just as a comment as to why repair shops may have lost the art of driveline repairs....so many manufacturers only use staked uni joints in their drivelines now a days. I know staking the unis is nothing new, but it is becoming more common. Why they (the manufacturers) do it I just don't know...is it cost, ease of production or something I haven't thought of??. Much more cost effective to get the expert from the driveline shop to restake new unis and balance the shaft. Less grey hairs and trouble for the shop I suspect.

@f114163 5 жыл бұрын
John, having watched this video. It seems to me that you are effectively centering the U joint between the snap ring grooves of the two opposing yoke ears - albeit with some axial play according to spec. That assumes that the snap ring grooves in each opposite ear are exactly the same distance from the axis of the drive shaft. Is that always the case? Assuming that the ear(s) aren't bent inward or outward.

That is a good question. I would suspect there is always a small amount of offset. Excessive offset can be checked by measuring the runout of the driveshaft while mounted in the vehicle after installing the u-joints. Thanks for your feedback!

+265chevy Hi, That is a great question! It is hard to find a spec! Most of the service information I have access to seems to have been written by cavemen who don't even check play. l did find a specification in several locations though. 1. The Spicer Parts website media.spicerparts.com/media 2. The 2007-newer Toyota Tundra service manual for dirveshaft inspection (They use all Spicer parts). 3. A u-joint inspection procedure from Lexus for some staked-in u-joints they use. What I discovered is: The larger the u-joint, the larger the allowable play. Large Class 8 trucks (Semi Trucks) have 0.006" maximum play (from the spicer website). Light duty trucks (Class 1-3) like the F-150, Tundra, Silverado, Sierra have 0.002" maximum play (From Toyota's manuals). Small diameter driveshafts like the Lexus has have a maximum play of 0.001" (from Lexus' service information. I would use the 0.002" maximum for your drag car. Best wishes!

EDIT: I found out that Spicer 5-1410X and 5-1410-1X kits come with 4 sets of selective snap rings, so this should fit the bill! Where can I get the colored snap ring sets? I had the driveshaft for my F-350 rebuilt at a local shop and it has a terrible vibration now. Took it back and they charged me $50 to tell me "nope, not a driveshaft vibration". I inspected each of the yokes and the center u-joint has 12 to 15 thou axial endplay, at least by my eyecrometer. I'll pull the shaft and do a full inspection. They replaced the center carrier too and didn't bother to replace the slinger or install the dust cap over the expose bearing! I'm not very happy with that shop, especially since they gave me the "you're crazy, get out of here" vibe. I'm so mad at myself for taking the "might as well have it serviced" approach when I took the shaft out. The original Spicer SPL209 joints were fine, just the center carrier rubber was deteriorated. I have purchased an OE replacement Dana carrier to replace the stuff they used. FWIW, all parts they used were Neapco, I'm very unimpressed with them at this time. Gonna have to do it all a second time, then have a conversation with the shop about getting my money back.

It seems to me that measuring the snap rings between manufacturers should always go with a measure of the actual cross measure, I bet there different, also the spicer's thrust washers, I think, may allow for tighter axial play as its between metal and plastic as opposed to metal to metal. I've been a "shade tree mechanic" for many years, your videos have cured many bad practices for me, Thx much.

Thanks for your feedback One of my other u-joint videos actually shows the difference in the cross measurements from 7 different brands. It is quite revealing. see kzfaq.info/get/bejne/eNCAed130LTRmnk.html

Hallo! I'm trying to overhaul the IRS of my Jaguar E-type 1969 4,2 FHC LHD I'm looking for any kit of snap rings/circlips with various thickness that can fit my u-joint but with less axial play possible? the snap ring delivered with the new u-joint is 1.7 mm , too thick! I've fit snap-ring 1,2 mm thickness but I measuring about 0.3/2=0.15 mm each side, too much! I need something around 1.4 (... 1.5 maybe) or something in between Where can I find this snap rings thanks for the help!

I don't know if you're common with Jags much, but this guy has something to worry about. The independent rear suspension of Jaguar design used U-jointed driveshafts not only in the purpose they sound, but they were also upper suspension arm (kind of upper wishbone). So this suspension design surely needs more attention than the others.

Very interesting. The Toyota book shows tapping the yokes (thick end). Is this to 'settle' the caps do you know? I honestly didn't know UJs were this in depth, like you say, would we treat other bearings the same? No!

+Toyota Tech Hi, yes, I have seen that part of the Toyota service information. It also shows using u-joint pulling tools that are no longer available for purchase; not very helpful. To Toyota's credit, they do show that checking axial play is needed and have given play specifications for years. I have looked at other manufacturer's service information for u-joint replacement and inspection, they look like they were written by a caveman with a hammer and chisel; no axial play is mentioned at all. Ford and GM are the only ones that show a u-joint removal tool that you can still purchase, but still no play or inspection. I have service manuals out of the 1950's that do a better job of describing how to change a u-joint than today's manuals. It seems like all the details have been slowly deleted over the years to a point where it is almost a lost art. That is why I decided I need to research this topic in great detail and try to restore proper methods, tools, and specifications to an industry that does not even know they are gone. Thanks for your feedback! No Hammers! ;)

Wouldn’t placing the dial on the drive shaft rather than the center point increase movement due to angular differences? Since we’re being so precise in the first place, I figured you would want to be as accurate as possible? I.e. the angle at the point of origin is increased the further away you move from that point?

Excellent series and very well laid out. I really learned a lot. That being said, and no disrespect intended, how would one charge for the extra time this procedure takes? I know in my mind without a doubt this is the right way, however, I don't see how you can perform these procedures within allotted flat rate time. I guess you could try and educate the customers and charge a premium. I just don't think that most people will pay what the job is worth. Again, I am sincerely meaning no disrespect. You have truly opened my eyes.

As much as I love these, some, ok most of these don't work in my garage. In fact, and I do this very, VERY carefully, but I pull the drive shaft out, clamp it softly in a vise, take my Skilsaw and put a metal cutting blade on it and cut the old U-joint out. It takes maybe a minute. Then, very carefully clean out the ears, with an air sander, until you can put the caps in by themselves, easily, then C-Clip them in. Saves time, grief, my garage walls have fewer holes in them, from not throwing as many tools at them. Life is better, the dog is happier. Because he doesn't get a beating. Lol, just kidding, I haven't had a dog in a decade.

You are calling out 0.00197" axial endplay in the video, but the chapter marks are 0.0197" axial endplay, that's an order of magnitude difference. The figure 0.00197" is close to the approximation for 0.05mm, so is the actual spec 0.05mm axial endplay? Put another way, 20 thou is a heck of a window and feels like too much, so I must assume the lower limit and take the spec to be 0.05mm.

That looks like a 1350, or 1410 u joint not a 1330. The 1330, and 1310 u joint only come with copper, grey, and green snap rings. The 1350, and 1410 spicers come with grey, gold, and purple snap rings. Also regardless of the axial play in the joints, balancing the shaft after replacing the joints is the best way. I’ve owned a driveline shop for a long time built 1 piece aluminum conversion hellcat aluminum shafts etc, and also have replaced u joints on used, and new drivelines steel and aluminum and never had anyone complain about driveline vibrations. Never have I used the grey, green, purple, clips in the spicer u joints.

This is a great video series. However, any real mechanic would starve if he works this way. Therefore, the method is probably unnecessarily accurate. Second, the new clip rings, once installed, look worse than the old ones. So the old ones are still good. Finally, most people beat on the ears and that tend to reduce the distance between them. So the cheap aftermarket ujoint might purposefully provide thinner snap rings. In reality, the vibrations is generated from seized up joints, not those with a small amount of axial play.
