Oh my god man, been lookin for a straightforward, quick and simple explanation of this for days now, so glad i found you! thank you for sharing your knowledge, i desperately need my truck working again
I put my e46 bmw driveshaft back together and it’s shaking. This video is a great tip on how to identify the static portion vs the articulating portion of the u- joint, how that affects the balancing and how to find a solution. Helped me a lot! Thank you
Was reading an ls swap book and it talked about phasing the driveshaft. Never heard of it before yesterday. Now you’re talking about it.Very strange coincidence. Thanks for the video though!
This works for all vehicles where the transmission or transfer case and differential are on the same plane. Some vehicles have the rear differential offset and not centered in the rear axle. This causes a two plane operation and a properly phased driveshaft might actually have one fixed yoke a few degrees twisted from the one on the other end. I would also caution hitting a driveshaft with a hammer and punch. A good paint stick works just fine without the added chance of knocking it out of wack. My guess is when punch marks are added on an aftermarket driveshaft is that they are done before balancing.
Thx for the heads up. I was searching just for this exact info. Especially the part about possibly being 180 out. Enjoy seeing you and Matt on TH-cam 😊😊
My wife's truck has a low bass drone after I replaced the center bearing. I marked the indexes but an end fell off and I eyeballed it. Now I know where to start in order to get it back to normal. Thank you!
Thanks, Matt. I love the fact that you didn't edit out the dropping of the shaft. Lets everyone know you're human. I'm a really old guy so I wouldn't do much but have you ever done anything on Liberty's? I have an '04. Thanks for sharing.
@@bleepinjeep Save me Matt. I did a boo-boo. Does this matter on a 1 piece driveshaft with a slip yoke? I'm in the middle of replacing my rear driveshaft's two u-joints. I didn't mark it for reassembly/alignment/balance/phase. Does it matter? Can I just assemble it however? Does it matter if the zerk is phased also?
@@bleepinjeep Muchas gracias mister! 🙏 I appreciate your response. The warehouse sent mismatched u-joints yesterday. The store just called me to say the correct parts just arrived. Woohoo 😁
@@bleepinjeep 💪😁💪bro 💪😁💪brooo 💪😁💪brooooooo Hey Brotaterchip I found a wealth of knowledge on this stuff. Check out WeberAuto on TH-cam. He has 7 videos on u-joint tech alone. Each is an hour long, ugh. Plus vids on runout, working angles, vibrations, NVH, and etc related tech. It's enough to geek out on and turn our brains to bubble gum. 🤘😩🤘
Thank you!! I have a Sprinter with a new drive shaft and it's unbalanced, I'm thinking I did not line everything up. In fact I know i didn't line anything up : D So thank you, I now have something to do!!
Hey, thanks for the info AND comedy routine. I almost lost it when you yanked the slip yoke off and sounded like it hit your four wheeler. For anyone watching and the splines are sticky try cleaning it and shooting some fresh grease into the grease fitting, or just wipe it on the splines once you pull it apart...carefully. lol
Great video! I’ve been chasing a vibration in the front end of my 2005 TJ for a wile now. Replaced ball joints, track bar and all joints in the steering. I’ll check that.
FYI some vehicles have out of phase shafts, the key to phasing is diff nose angles. if you have a raised diff nose, the prop should be phased. Also 90° is the equv to 0°. 180° is equiv to 0°, the only difference is as you say, balancing if applicable.
Hello,was trying to find a drive shaft video you had with the long travel splines,but can’t find it, I found the 7” ,but not the long slip one I seen in a video, I need a longer shaft,so figured I would get the longest slip travel so no worries about separating thanks,
Not all driveshaft are phased Straight Like That . On my Scrambler XP1000 S both the front and back driveshaft has offset phases because the input and output shaft are at different angles.
I heard that Bleepinjeep had a video on how to install a flux capacitor into your jeep so you could have a time machine. Apparently the government ordered Matt to take it down, after someone used a Jeep to help George Washington to cross the Delaware.
Now lets say that each U-Joint has a grease fitting in the same place, in phase will they be on both ends pointing up or down in the same direction, or, one fitting pointing up and one fitting pointing down 180 degrees away from each other?
@@bleepinjeep landrover do the same thing, believe its to do with the length of the shaft. Landrover have the at 45deg out (or somewhere like that) I've tried my 90 in and out of phase and didn't see much difference.
Will a driveshaft out of alignment cause a clicking sound? Nit while driving, but when accelerating at a stop. BTW, where did you get that shirt? I dig it, lol.
Is that test drive in 4WD or would we feel it in 2WD just the same? I personally have warn hubs up front and lockers...obviously I wouldn't test it locked but hubs engaged if 4WD is necessary.
Hey man, love the shirt. Just ordered one and I'm never taking it off. XD Could you maybe tell us how to adjust the rear pinion angle on the 8.25 rear axle on a 1995 to 2001 XJ? I keep blowing u joints on the rear and my yolk is starting to go out as well, I already have a rear end rebuilt kit with a new locker so I'm okay on that. Thanks Bro-tato-chip.
@@bleepinjeep What if you cut the welded seam out of the smaller tube and stuff some round bar in it and weld it back up? ..maybe something with a lot of carbon in it? ..then maybe some like vertical gussets along the outter (bigger) tube. Lol I just think it would look cool. I heard of the concept years ago but have yet to see it in practice, there's probably a real good reason, huh? Lol thanks for your reply.. Respect
My XJ has a driveshaft vibration I cannot get rid of. Tried everything, SYE, new shaft, correct shims for the rear. Even picked up adjustable upper control arms to get the front pinion at proper angles. You should do an episode like the problem im having.
If I have a 5” lift on my 1999 Jeep Grand Cherokee what length front drive shaft should I get? Or is the stock ok to keep? Thanks mucho bro! Keep up the great work.
Hey Im new to driveshaft science... does a double cardan joint on one end provide issues when a single u joint is on the opposing end? That means theres 3 u joints total right? I would think theres a failure to cancel sin wave.
Can a misaligned drive shaft cause transmission damage? I think I might have misaligned mine and now i have a constant loud whine at all speeds in forward gears coming from the automatic transmission.. Im afraid i just destroyed my transmission...ughhh
@bleepinjeep Thanks for the reply. It seems my sprag/one way roller in the 4l60e transmission somehow became damaged and is causing the noise. It's either a rebuild or time to replace in order to eliminate the constant whine. Talked to a driveline shop and said I need to put c-clips/retainers on the rear shaft- rear ujoint and the front shaft- front. I figured since it had the ujoint clamps with two 11mm bolts on both side that mount to the differential yokes, that they didn't need em for my application. But it sounds like they are moving around while driving causing the heavy shaking at mid n higher speed. Gonna reinstall n see if that fixes the problem. Live n learn

Nice, I was thinking the 180 thin as you were explaining this.
Very cool!
I don't think I have ever not laughed at some point in any of your videos!
You just saved me a lot of headache and money I don’t have. Thanks, man
Couldn't get my shaft back together, indexed it as the video showed and went right on, thank you!
Man, I love learning new things. Could explain why I couldn't get the shake out of my ranger. Thanks dude from Kelowna Canada.
Thank you!! I have a Sprinter with a new drive shaft and it's unbalanced, I'm thinking I did not line everything up. In fact I know i didn't line anything up : D So thank you, I now have something to do!!
WOW!!!!! I had that problem once!! Only my woman lined it back up😌!!!! NOT,, but really, that's a good tip! Thanks Matt!!

Good tip. I've had this issue on Toyotas in past when working on drive train .
Useful info. Never really checked mine, always assumed it was fine when I got it. Turns out, both front and rear were out.
Thank you, you explained it better than other youtube videos
Great vid! Actually I am watching it to properly assemble the driveshaft on my 1/24 scale RC crawler 😁
Thanks Matt, I like the lil punch marks 👍
Great video! I’ve been chasing a vibration in the front end of my 2005 TJ for a wile now. Replaced ball joints, track bar and all joints in the steering. I’ll check that.
Ill give it a shot
Guy sounds like Mr Roger's, I was waiting for him to change his shoes and put a jacket on...lmao
Great quick tip

Great Stuff, keep up the good work.
For Balancing purposes
Informative video👍

I swapped pulled my transmission and put it back and its been grinding at bell housing for 6 months turns out this was it 😯
I had no idea, thx!
Good info, thanks for sharing.
Safe bet is to check the factory service manual. There are some prop shafts out there that are phased 90°.
Good video, but I really just liked it for your shirt lmao
Learn something new every day! AND yes lube!
Just a great video
Glad you enjoyed it
I just ripped my drive line apart while swapping the entire jeep to a new frame.
Good to know.
Thanks, good lesson
Fantastic
Thanks
Very good
You just saved my life bro,thankyou!..#yotabeatsjeep 😄
I lol'ed at that
If it is off one spline grove , how many degrees would that be ?
good information ! Now if I could find an old school auto machine shop to re-balance one after I shear a weight off WITHOUT a time machine
I heard that Bleepinjeep had a video on how to install a flux capacitor into your jeep so you could have a time machine. Apparently the government ordered Matt to take it down, after someone used a Jeep to help George Washington to cross the Delaware.
I just learned something i didn't know before. Cool
_"this needs to line up exactly with this, so what you would do..."_
*AAHHH*
*MMRRAAAHHHH-oh!*
TY
Now lets say that each U-Joint has a grease fitting in the same place, in phase will they be on both ends pointing up or down in the same direction, or, one fitting pointing up and one fitting pointing down 180 degrees away from each other?
Paint marker before removal…. Lesson for me learned
Always great stuff..its the simple things folks forget..i always notch mine or mark it somehow ..k.i.s.s. right
FYI if you’re ever working on an FJ80 the front shaft is 90 degrees out of phase and the rear shaft is in phase.
Cool, why is that?
Not sure but I found out the hard way. Dealt with vibes for a long time till I found the info on ih8mud.
90 degrees is still in phase...
@@bleepinjeep landrover do the same thing, believe its to do with the length of the shaft. Landrover have the at 45deg out (or somewhere like that) I've tried my 90 in and out of phase and didn't see much difference.
Good vibrations? Tips and shafts? What kinds of channel is this?
Nice
Will a driveshaft out of alignment cause a clicking sound? Nit while driving, but when accelerating at a stop.
BTW, where did you get that shirt? I dig it, lol.
Hmm I never knew that
👍😉
Don’t forget to lube the shaft.
That’s what she said
Always
Cool 👍
My driveshaft is totally going thru a phase right now...
😂
great vid!
Would a UJ's zerk/grease fittings have any play in the phasing of a driveshaft? Thanks!
What about a stock front drive shaft, if you replace the cv joint? Thanks.
Hello. What angle do I have to give the pinion. it's a cherokee zj raised 6.5 "
My gf wants to know why the shaft is sticky🙄
Because she was slobbering on it. XD OH SHIT. LMFAO. JK JK DUDE! Sorry, it was to easy.
because it needs cleaned every once in a while
If the hard parts were 180 degrees off would it not still be in phase?
What if you don't have a double yoke driveshaft .how would you setup a single yoke shaft off a vx commodre
Is that test drive in 4WD or would we feel it in 2WD just the same? I personally have warn hubs up front and lockers...obviously I wouldn't test it locked but hubs engaged if 4WD is necessary.

What are your thoughts on the home made square tube inside square tube drive shafts?
Works but a lot of times I will hit a rock with my driveshaft. Wouldn't want to try that with square tube.

no it doesnt

I would give adams driveshaft a cell and discuss. You probably need an sye at 5 inches
BleepinJeep thanks!
BleepinJeep but I think it’s 4” I bought it lifted
2:12 ok, and what if my propshaft is a splined 2 piece, with 3 holed rubber joints on both ends? how do I line up those metal 3 spokes to each other?
Is it possible to flip the double carden joint out of phase or is it just on the shaft itself?
Just the other end.
Hey Im new to driveshaft science... does a double cardan joint on one end provide issues when a single u joint is on the opposing end? That means theres 3 u joints total right? I would think theres a failure to cancel sin wave.
No but the angle of the pinion has to be set up different, I have s video on this somewhere too.
So, what you need to do is... muuuaaaaaaaaah!

Always wear gloves when handling a dirty shaft
