Finally a simple to the point explanation, I have a terrible vibation over 65mph and I now feel like I can measure the angles and hopefully correct it, my upper control arms are adjustable so that should help.

My husband thanks you for confirming what he felt was true, but was continually told otherwise. Appreciate the help!

You are a great teacher.Simple,straight to the point.I like the three things to remember. Thank you for this!

Excellent, to the point information presented in a clear concise presentation. THANK YOU !!

Clear , concise and very informative. Thanks

Good video, well explained. Clean and short.Thank you!

Awesome video you made it easy to understand I've always had a slight vibration definitely going to have a closer look at those angles thanks

Great info, clear, concise, easily understood. Thanks, Jack

Thank you for the well made and very informative video. I've been fighting an issue with a new build for weeks. Looking forward to getting back at it tomorrow

Excellent presentation! Thank you.

Very good information. Most impressive is the way you present it. Very well spoken. Easily understood. You are a great presenter. Well done.

Great video. I'm fighting a little vibration, and I'll use your technique to verify my angles. 👍 Update: It worked. I found that my pinion was pointed down by 1.4* and my transmission was down by 2.2*. No bueno. I've ordered the adjustable upper control arms to resolve this. Guys like you, make neighbors think I know what I'm doing. 😈😉

Great info, hope to see a video about a leaf spring car pinion angle setup.

I watched other videos and no one mentioned numbers, what's good,what's bad. Thanks, great video.

Excellent well-spoken and informative. Going to use your tips and see where she sits. Thank you. Great job. I learned alot👍✌🇺🇸

I never ever learned this much in such a little time like this thanks!!

right to the point for anyone to understand . finally a info video that was not a waste of time. thanks !!

Finally some clarity, thank you sir!!

Straight to the point, easy explanations, no BS. This earned a Sub!

So damn helpful. Think I may just have discovered the source of driveline vibration in my 70 Boss 302!

best video on this complex topic. TY

Awesome video!! im just starting a hotrod project and that was extremely informative and helpful thank you!!

That is some good information. Thanks for the tip on the ap

Well explained you answered my question on how to set the motor and trans and rear awesome video

Great information for my build!!

Best video on the topic i seen so far.. Good job buddy

Great video thanks a bunch.Very nicely explained.

FANTASTIC. JUST THE RIGHT AMOUNT OF INFO FOR THE SPECIFIC SUBJECT. MUCH MORE FOR DIFFERENT APLICATIONS

Thanks so much for this video. I was so confused how to set my pinion angle. Especially with the tremec app. You've explained it very well.

the best video on this subject ive ever found, good job! Subscribled!

Nice video. Thanks. My propshaft is only 6" long with quite a big angle. Will have a play with the 4 link settings.

Well done , thank you - Australia !

Thanks. I just put 4.56 in my car, now it vibrates like crazy at 65mph. I noticed my rear diff is pointed down and so is my trans. I just ordered adjustable upper control arms to hopefully bring my diff up to match the trans angle.

Excellent video! Very smart man. Thanks.

Well Done, concise and explicit.. I shall now double check engine angle using front pulley

Excellent video.

You made it very easy to understand thank you

Sketch at 6:00 does not show proper out of 'phase'. Do you check the crank pulley in different positions? It is also part of Harmonic Balancer I believe. Rubber mounted. Great explanation. Diff and Trans shafts should be Parallel.

Thank you for the simple explanation! I just did a QA1 coilover conversion on my 83 C10 and have been trying to find an explanation of how to set pinion angle. Thanks for the 3 simple rules towards the end.

100% right on! Great video!

Very well explained!

Thanks you made it so simple to understand. Cheers & stay safe

Awesome video! Thanks

Thank You sir for this straight forward information. Just subscribed to your channel. An old hot rodder told me set up engine angle about 3 degrees (downward) just like your explanation. Great 👍 information, I’m setting up my driveline in me 54 Chevy 3100 now. Definitely using your video for information.

Dude,off the pully is Hella smart, I been using the small output shaft.thanks

Thank you for a great video. I have the app now.

Great work.

I learned something today. Thank you.

Great video! Subscribed.

Nice that Dodge/Chrysler set the pinion angle on my challenger to blow out the pinion seal every 20,000 miles. Fun job!

To my understanding, carburetor pad on most street intake manifolds 3 to 3.5 degrees. That instructs fairly well regarding engine setup which the driveline must mesh with.

Nice video. A bit different but have been chasing a vibration under hard accel on my Jeep after a small lift. I know I need a double cardan on the rear to help but I measured anyway and found my vibe.. I had an operating angle on the rear driveshaft of 8.3 and my pinion was a degree off the drivetrain. I have adjustable arms and dialed a degree out of the pinion to match the 5.5 degree powertrain angle, now have 7.3 operating angle with a bit less vibration but still there.

Very nice work ,great video thanks for sharing

Awesome video. Helped a lot swaping my Abody 8.2 Axle in my gbody malibu!

Fantastic explanation 💪 😎 Thank you

Great video thank you

Great video!

72 Chevelle here with a TKO600… I was told by a circle track guy to keep the pinion angle slightly down. So I have a downward trans and a downward pinion. I’ve been chasing this vibration for a few years now and I’ve never been told to point the pinion up. It all makes sense now.

Very good job explaining everything. Thanks for the info on the angle finder from the toolbox 🧰. I’m 63 and been messing with vehicles as long as I can remember, I was taught to level the intake as close as u could to level the carb and get the best angle for your driveline. Like to see one on leaf springs. Great video 👍

Good video you gave me useful information 🇦🇷

Great info thanks!!!

this video is great, put things in simple terms that the shade tree guy can understand.

Great video!! I just installed a Gear Vendor in my 66 Chevelle. Vibrates at about 65 and up. Guess I was hoping to get lucky with the pinion angle. I am going to use this instruction and see what happens. Will post the results. Thanks again!!

Excellent video. Thank you. No need to watch any other videos for this application. Which is a rarity. I normally have to gather information from several videos and come up with my own plan. But not this one. Everything is covered. Thanks pal

Solid info! It's a misunderstood thing - the amount of difference it can make in your car is unreal at speed.

Great video, exactly what i was looking for, but i have a question... My mustang has independent rear suspension, can i check these angles on a 2 post lift without faulty readings?

Great information 👍👍👍

Good stuff, thanks.

Just a tip...You should address whether the setup is a W or a Z config. You are correct as far as a Z config goes but most cars have a W config on the shaft. The upper arms will be too short to accommodate as well as the prop shaft may contact the floor in certain instances. The same also works in the overhead view...you need a consistent setup (W or Z) in BOTH planes for the joints to be happy. Nice video and presentation...hope this helps.

Good info!

Very interesting! Any hints on a dual pieces driveshaft?

I haven't driven a car since 1989, probably never will again, but this is interesting to me and your presentation was informative and easy to follow.

Great vid. But one thing I never see anyone explain is the left to right adjustments. This is great for up and down, but what about left to right? Not all differentials and transmissions are perfectly centered in the middle. Any thought or help with this? Thanks!!

Great video I'm working on a 36 Chevy that has a shake at 60 will checking allll that

Good stuff thanks

excellent video ! do you have one with leaf springs ? im about to narrow my 8.8 and would love more confidence building videos such as this

While watching your video I am wondering how I have been successfull in my ventures without this knowledge. I have converted two different coil spring rear ends to leafe springs and installed them in my 67 g10 van. No vibrations from either one and the second one has been in use more than 10 years with no u joint failures. I angled the differential to suit my eye and welded the spring perches in place. Tape was used for left right balance and parallel with front axil. Going to recheck soon with this method. Thank you.

Thank you so much!

Great info. I have a 41 ford with an 8 inch rear end and parallel leave springs. How should I set the pinion angle?

I've always heard point the nose of the rear end up 1-3 degrees. If you point a go-pro at your 3rd member and go for a drive, you'll see that the pinion angle changes quite a bit under load.

Perfect info

I changed leaf springs on the rear of my 72 charger. also changed front shackles too. Then had a 3.90 ring and pinion installed. Ever since then (2018) the car had this vibration you could feel when u let off the throttle in 4th gear at highway speeds of 55-60 mph. It seemed to smooth out when u got back in the throttle but it was ever so slightly still there. New transmission mount, new cut and balanced driveshaft too by a reputable driveline service company. I recently realized the front leaf spring shackles were in the 1.5" lowering position. I Switched it back to the original ride height mount on the shackle and the vibration is still there but not quite as prominent. At this point i plan to check my pinion angle and engine/trans angle. from what i am understanding the angles need to be as close to equal but opposite ? my buddy recently redid the ring and pinion for me too and he thinks the pinion is too deep in the ring gear but i have found information suggesting that a ring and pinion wont vibrate , only howl or make noise. Great video by the way. i look forward to checking my angles. I have a suspicion that the newer leafs and trans mount could have thrown my angles off. In any case i figure it be best to check all angles and make sure they are in an acceptable range before it messes up the new ring and pinion. what are your thoughts? thank you

cool. thanks for info.

You should consider mentioning whether or not a double cardan is used up front; if it is then having parallel angles with the front and rear does not apply. The pinion should be inline with the drive shaft in this case

Thank you for the video - i thought inline straight was the way, bad vibration all speeds going to get it right now

Spot on 👍

Very informative but I have a two piece drive shaft on my 1963 C10, which ai have lowered. Can you explain how to figure out this same process for the two piece drive line?

Great video well presented. You mentioned that you a basing the pinion angles on rear coil springs. What is the degree tolerance when using rear leaf springs to allow for wrap up under torque?

Great video. 1 question, do you zero your angle finder before you start?

Great info, thank you. Need advise please. I'm unsure on how I'll be able to get an accurate angle to weld the perches on the rear end. I'll try to explain as brief as I can. Have a 1940 Ford pickup down to frame. Installed mustang 2 front end with setup rods and lower controll arms are currently parallel to floor as suggested by Heidts. Istalled leafs in the rear and using a flathead engine, C4 trans and 9" rear end. I can only guess on what the ride height will be because there is no wheels or weight on it. The only thing I can think of is keeping centerline of axles the same dimension off floor and hope that would be the correct thing to do?

I Need than. Thank you man 👌👌👌

Hi just watched your video, has helped me understand the principle behind the angles, I am using hydraulic rams and engine is set a 3 degrees and Will be setting ride height about 2” of the ground on my 53 Chevy BelAir the rams have approx 6” travel up and about 2” down from ride height they have 8” travel total, do you have any suggestions for setting up this arrangement for example when I drive down the road with back end down and front up about 5” what will the pinion angle be like for driving ? Thanks Mark

excellent info, would the concept apply to a truck on leafs?

I swapped a different make engine and trans into a car I have. I know my angles are off because it vibrates above 65 mph. This will help me out a lot. 👍🏽 I'm going to look into getting this App so I can get the drivetrain dialed in correctly. 👏🏽👏🏽

Is the center line from trans to differential also a factor of alignment? Later line trans to diff.

Great vid... i have annoying vibration in my chevelle... im trying to correct it asap

What is your advise when using a Jaguar IRS rear? The pinion on the diff is not centered left to right, it's offset to the passenger side. Also note that the diff input flange NEEDS to be vertical, 90 degrees to the road. This is to keep the control arm pivots correct. In my application I also have the engine/trans at 0 and the same height as the diff input flange. Meaning crankshaft, trans, diff input are all in a straight line HORIZONTALLY. There is a few inches offset left/right, but still parallel. The driveshaft is very short, about 18". Oh, and the diff center is solid mounted, does not move with suspension travel so no change in pinion / driveshaft angle.

Great video and explanation. One thing I would like to know. Do you zero your angle finder on the ground or on the chassis of the car before starting?

I watched your video, great stuff! I'm fighting getting my pinion adjusted. My crank pulley is 4.6 degrees and I can't shim my transmission any higher than what it is. I can get my pinion up to the 4.6 but isn't that an extreme angle?

Fantastic this guy knows what he is talking about so well explained just one thing I didn’t get the name off that app as I am nearly deaf please can you inform brilliant video please let me know buddy cheers Larrysullivan in london
