Awesome. I have been reading a lot of forum posts on lifts and never could figure out the theory behind lifts and getting the drive line in sync. Nice to see a young kid that has so much good knowledge and the ability to convey it so well.
Great video! I'm pretty sure about 80% of off road shops don't even know how to fix this, they just install whatever is in the kit. Also, you remind me of Cameron on Ferris Bueller's Day Off! Oh, cool cat.
Well, I thought your explanation was great, fantastic even. I purchased a set of rear leaf springs that had single 3 degree shims fitted to each one "supposedly" to correct the pinon angle being raised to far after a 2" lift on my 4x4. That's all well and good but they had the shims facing the wrong way around with the thin side to the front which I now know made it worse. So, I went out and bought larger shims & fitted them the same way again which only made things even worse and I couldn't work out why. I now know why, so thank you very much. I should be able to get it sorted out now. Cheers.
You killed it. For some reason, the way you explained this concept made me totally get it. I'm an educator myself, and if you haven't already, you should consider that career!
Excellent educational video most people would simply install a kit without paying closer attention to the shift in the structure of the vehicle and how important the angles are for vibrations, wear and tear.
Just got my bronco back from the spring shop for new springs and 1 inch lift, it’s vibrating like crazy. It appears they set it up for a single joint and it has a factory double cardan! Thanks for the very informative video. I know what to ask them about now
Excellent video! Installed slightly taller springs on my Lexus GX and now getting a slight vibration at highway speeds from the rear end. I think this is the issues and your video explains so well what it might be. Thank you.
Great vid. I'll add it's recommended to have the rear diff down 1 degree from the transmission / transfer case output. When you're driving it will torque the rear differential and it will lift a small amount. That way when you're cruising they're parallel but parked it's down 1 degree
this actually helped me a lot. I was installing my CS009R springs and I had the axle resting on a jack while I was working on getting the axle lined up with the pins on the springs and it rolled and the slip yolk came out of my drive shaft. I thought I got it lined up the way it was but then I had massive driveline vibes at highway speed. A little research lead me to YotaTech which lead me here and I realized I was about 70-80 degrees out of phase. took my shaft off and I found an old match mark so I lined up in the zerks and got them all lined up with the yokes in line on each end and boom no more vibes.
Awesome vid. Love those old yotas. I was going to purchase the same skid plate it's good to know about pinion angle change. Would rather install all parts needed when your underneath the truck. Keep the build going looks awesome!
Thank you. I'm glad you liked the video. The BudBuilt skidplate is a nice piece but it will change the pinion angle. Having all the stuff at once is a plus. Thanks for the feedback.
Some Great Vids Alex.. I have an 87 4x4 pickup and your videos have helped me out a Ton.. just installed new 2" OME leafs, shocks all around and bj spacers..and have a slight vibration now, looks like some shims will be the fix
Watched your video on pinion angle, and it was very informative. Had a question though, if the angles were reversed, meaning if the rear was 86 and the front was 82, if you use the axle shims would you put the in facing the opposite way as shown in the video. Hope this makes sense.
Thank you for this great video. Very informative. So I may not need to buy a SYE and a new drive shaft. But before I do anything I’ll buy a inclinometer to get the angles correctly measured.
Loved the video thanks, can you explain how the angles should be on a 2 piece drive shaft I have a shutter on take off only, has a 4" sky jacker lift installed
Minimum Operating Angle Of 1/2 Degree A slight angle is required to prevent U-joints from wearing out from brinelling, providing a smooth flow of power through the driveline. It is similar to intentionally putting a pre-load on a wheel bearing. Maximum Operating Angle Of 3 Degrees
thanks for sharing, this answers a question i had about the driveshaft it's self...i have a 4runner almost restored with the same vent windows...Creator bless...doug
ok. i own a freightliner truck. my transmission is 4 degree down. then i have 4 U joints after all the way back to the rear end. its a 3 piece shaft. also i have 2 center bearings. the rear end in 10 degree UP. and the shaft is about 1 degree on all the joints. I'm having a big vibration after 50 mph. i have change all the joints. tires. rims even the shaft. what do you think i have to do? do i have to bring the pinion down? and how much down? ( and its a very long shaft to.) tks
Great video, thanks but i have a question what happens when is a 2 piece driveshaft? Im doing an axle swap from a newer truck and is bigger then my stock one
WOW thanks that was useful. i want to get a 6" lift kit for my k20 suburban and i dont want to lower the drive case how i can do that? get longer drive shaft ?
Great video. Using shim will solve pinion angle problem. But it will lead to change in caster angle which In turn will largely affect the stability of the vehicle at high speeds.
Thanks for the vid....just to confirm, putting the fat end of the wedge forward towards the pinion/front of truck, is how you lower the pinion angle, by pushing the axle down , is the correct? all over tacomaworld, there are people saying that the skinny side goes forward, i'm pretty sure that would tilt the pinion up..?
loved the video i am quite a car guy myself i do it for a living i was wondering if you have any info on angles for the new constant velocity joined drive shafts jeeps are running basically i have a customer killing those shafts with a bad lift kit and wants the cheapest least mods to just fix that angle i was thinking shimming the tranny lower where it bolts to the frame prob cheapest fix any other ideas or any technical info on the angles and levels required for those?
You have a talent to teach as well as being a good mechanic. Thanks for posting this...very informative.
Excellent tutorial on what can be a very confusing subject when simply explained and not shown. Well done Alex.
this was one of the best videos I've found describing the reasoning for shims and driveline angles. Thanks!
Wow, a video that actually shows you how to fix something, not just identify the problem. Thanks
Videos like this are hard to find. Well done!

This is literally the BEST video I have found about pinion angle!!! Awesome work man. Subscribed ✅
I cannot thank you enough for this video. I had no idea how to correct the pinion angle after adding lift blocks. Great explanation.
Same hear. Bad vibes at 70.after tapered lift blocks
You killed it. For some reason, the way you explained this concept made me totally get it. I'm an educator myself, and if you haven't already, you should consider that career!
Well done. You'd make a great teacher .....if you're not one already. Keep the tutorials coming!
This is exactly what I needed thanks dude. I was struggling trying to find a solid video that showed and explained everything
Excellent educational video most people would simply install a kit without paying closer attention to the shift in the structure of the vehicle and how important the angles are for vibrations, wear and tear.
I comment rarely, but this was perfectly explained! I don't need to watch another video on drive-line angles. Thank you
Great explanation, i now have a better understanding of drive shaft vibration, thanks. I like how you explain while drawing
Hey Alex, thanks for creating this video. You made a complicated topic easy for me to understand and helped with my own lift project. Keep em coming!
Toyota, hire this guy now.
Excellent video. Clear and concise. Thank you.
Best video on springs I’ve seen! Good job 👍
That’s the best video I have watched on the vibration subject. Thank you
Cameron from Ferris Buellers Day Off did a great job explaining pinion angles. Thanks!
GREAT video! THANK YOU for the good clear explanation
Finally someone who explains this to where I can understand thank you
Excellent video. Very well said. Good instruction, very thorough. 👍
Thanks for explaining this clearly and also providing solutions! Great video!

Ben watchin driveshaft videos last hour.... this one makes sense!! Time to get to work!!... thank man!
Great video -- thank you for the effort you've put into this!
Thanks! Just the info I needed! very cut and clear!

Finally a good explanation of how this works!
Brilliant. Outstanding explanations mate.

Great video, and your correct Paul is the man!!
well done and very well explained by someone who really knows stuff.
Thank you great work absolutely brilliant clear and straight to the point from Australia.
Great video overall. 👍Some good info I needed to align my pinion angle.
Some Great Vids Alex.. I have an 87 4x4 pickup and your videos have helped me out a Ton.. just installed new 2" OME leafs, shocks all around and bj spacers..and have a slight vibration now, looks like some shims will be the fix
Glad I was able to help out. Hopefully the shims cure your problems.
Great video have a slight vibration after lifting my Jeep more so I'll try this. Thanks
Great video!!! Thank you so much for this through explanation! I even went and explained it to my wife... AND SHE UNDERSTOOD! :)
Great vid - you explain things so well
Best pinion angle video on RUclips.
Watched your video on pinion angle, and it was very informative. Had a question though, if the angles were reversed, meaning if the rear was 86 and the front was 82, if you use the axle shims would you put the in facing the opposite way as shown in the video. Hope this makes sense.
Glad I found this, I may have installed my shims in backwards. Good info👍🏻
I did TWICE...
Great job man. Very helpful!
Perfectly explained, good video
Very informative and addressed my slight vibration in my truck
Good explanation.... thanks for taking time to post......
Great explanation , thank's !!!
Great info, no bs. You may have just saved my jeep!
Great information. and Yes! you have a talent to teach. Great video.
👍👍👍👍👍👍. Thank you for this video. U just save me $400 on a drive shaft I didn’t need. Now the vibration is gone on my Jeep.
Awesome video and explains the why and how to fix the issue.
great video very simple and easy explanation
the beggining was my favorite lol
Very well done young man, 2 thumbs up!!!
Thank you for this great video. Very informative. So I may not need to buy a SYE and a new drive shaft. But before I do anything I’ll buy a inclinometer to get the angles correctly measured.
🙌🏼 thanks bro my grandfather said a simple idea making a big difference.
Great explanation, well done.
great information, great video!
Explained perfectly!! Thanks!
Loved the video thanks, can you explain how the angles should be on a 2 piece drive shaft
I have a shutter on take off only, has a 4" sky jacker lift installed

Thanks for this vid it helped me with my yoda🤘
Awesome video! What I wonder is if this fixed the newer Tacomas that have the carrier bearing?
Good video, very educational.
Thank you for your good explanation
Thank you. Excellent teaching skill here, teachers take note. SUBED! :)
Alex your video is A1 and yes Paul at 4Crawler makes some nice gear
Very informative video thanks
Great video. I will definitely be sharing your Chanel :-)
Thanks for this info in this video
I appreciate this video, thank you
Yeah excellent tutorial :) thanks !!
Really like the video, thanks.

Glad you enjoyed it. I really liked how this video came out. Dixie used to be able to fit under doors but she has grown to be quite fat.
Great job explaining it
Great video, thanks but i have a question what happens when is a 2 piece driveshaft? Im doing an axle swap from a newer truck and is bigger then my stock one
Nice Job Alex
Great video! Thanks!
WOW thanks that was useful. i want to get a 6" lift kit for my k20 suburban and i dont want to lower the drive case how i can do that? get longer drive shaft ?
Very well explained !
Wow awesome explanation
Thanks for sharing!
all makes sense to me now...thanks much
Great video.
Using shim will solve pinion angle problem. But it will lead to change in caster angle which In turn will largely affect the stability of the vehicle at high speeds.
No such thing as caster on a rear axle (without steering).
Thanks for making that. I lifted my S10 and have bad shakes from the driveline. I think that was the issue
Well done.... Thanks!
