Parts dont last forever, in this short video I share with you how I set up the rear drive pinion angles in relationship to a double cardon drive shaft! Once the set up is set, we lock that setting in by installing brand new upper adjustable control arms. This video shows you exactly what you need to get the job done. No math, no purchasing of special tools no nonsense Involved. Check out the free RIDGED app, you can download it FREE on the android and apple app stores! Ill provide you a link below! This tool is free and can be a Huge benifit for a DIYer setting up rear drive angles. I hope you enjoy this video as much as I enjoyed making It, thanks for watching! 🍻

Good for a double cardan shaft. If you have a stock shaft, you will want the pinion angle 1 degree "higher" (diff lower) than the transfer case.

@ATEMOFFROAD Год назад

Yes for those shafts, I don’t run adjustable control arm or lift without some kind of transfer case drop to correct the angle. If I had to adjust or check, I keep the pinion parallel to the transfer case.

@Wasted_wages1228 9 месяцев назад

Thanks for sharing your expertise. Question: my drive shaft angle is 13.6, pinion is 3.6 and caster is at 5.4 So do I need to rotate my pinion to go at around 12? It’s for a 2008, jk on 3.5 lift 37 inch tires

@ATEMOFFROAD 9 месяцев назад

The only real way to achieve perfect caster is to clock the Cs. Now that the jeep is lifted the pinion angle is the main concern. The best setup for pinion angle is anywhere between 0-3 degrees in relation to the shaft. As you rotate the pinion up its angle will increase and the shafts angle will decrease. So it won’t necessarily be 12 degrees, pinion should be 0-3 degrees in “difference” of the shaft angle . 12 on the shaft 9 on the pinion 12-9=3 , so a 9, 10 or 11 would be acceptable. Just keep in mind that as you increase pinion angle shaft angle decreases. Play with it and Find the sweet spot. 🍻

@huntero3225 4 месяца назад

Does this information transfer over to a leaf spring set up

@ATEMOFFROAD 3 месяца назад

Yes, but you would still need an SYE and cardon drive shaft and use shims rather than adjusting arms. You would also need to account for axle wrap. Better to be around the 3 to 4 degrees as the pinion gets loaded there will be some flex or wrap in the springs. So the pinion when load remains in the sweet spot between 3-0 degrees. Which I do discuss in my Jeep XJ lift kit install video. 🍻🍻

Hi ! Excellent video. Thank you. I replaced my rear control arms and corrected my rear pinion angle at the same time. I have a question though. I set the lower at the same length but when I tried to install the second upper control arm, the hole in the bracket and the one in the sleeve did not align. Is it normal that the left upper not to be the same length as the right ?

@ATEMOFFROAD Год назад

It’s ok to be a different lengths as long as the axle is square to the frame, and you don’t have any vibrations. The fronts are usually where there’s a problem but off 1/2” or less is not a big deal. There can be some variations on the axle mounts. 🍻

How do you drop the rear end angle

@robertrussell143 2 года назад

so whats the angle off transfer case to drive shaft? thats a big factor in vibrations as well!

@ATEMOFFROAD 2 года назад

Absolutely, if you have a factory driveshaft with only two U joints then the transfer case angle does matter in relation to the factory driveshaft and pinion angle, especially if you have a lift and or transfer case drop. But if you are removing the transfer case drop , have a lift , installed a SYE kit and adapted a double cardon driveshaft, are using the factory skid plate and the lift isn’t over 5” then we can assume your transfer case is in the factory position and the double cardon covers the angles for the new lift height. The transfer case is bolted in the factory position and can’t be adjusted. The pinion angle is what we need to correct! Thanks for watching 🍻

How would I adjust the angle of the pinion with a leaf spring rear end. I have a 1993 wrangler.

@ATEMOFFROAD 23 дня назад

@@msc1064 it just depends on what you have tell me more about your setup? On a tj with spring coils you have fixed upper and lower control arms so the pinion doesn’t move. On a leaf sprung suspension on a YJ or XJ the axle is not considered fixed and moves upwards under load. So pinion angle in relationship to driveshaft should be around 6-4 degrees. And the axle is loaded it will move upwards into the sweet spot of 1-3 degrees. This is called axle wrap and should be accounted for during setup on leaf sprung suspension. A little different than a tj. I talk about it briefly in this video Jeep Cherokee XJ Build - DIY 4.5” Suspension Lift kit Installation ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dnDXSVpsp7Y.html

@@ATEMOFFROAD I have a stock YJ and when I put new stock leaf springs on it changed the angle of my drive shaft I am not sure of the angle. I also don’t get any vibration either I am wondering if I need to do anything else or just leave it alone or maybe put a SYE on it. Like I said I have no issues at all. Just trying to be pro active

@ATEMOFFROAD 23 дня назад

@@msc1064then I would do nothing if they are the stock replacement springs. Keep in mind there are several other way to correct problems, For every one 1” of lift it’s about 1/4” of transfer case drop you need to correct the driveshaft angles on a leaf spring suspension. A TC drop is the (cheapest) way to correct a problem with driveshaft angles front and back, but Most don’t like doing it this way because it affects belly skid clearances. It could be that simple for you depending on budget and your needs, but it’s not very conducive to offroading like an sye and cardon driveshaft upgrade would be. which I recommend on anything over 3” lift. Especially if you’re going to be offroading your jeep. And here’s the problem with that, is if you are very serious don’t spend money on your old TC, spend 3k and do it right, and replace your old transfer case entirely with a 5.0 atlas 2 transfer case and up your crawl ratio to 100:1. It’s the ultimate option with a driveshaft, So as you can see there are many options here I’ve been through them all and they all work, but it’s all about how serious you are.

I sure appreciate your video it helped me alot with setting the rear pinion angle. However now im having driveline vibration issues up front and cant find a single thing to help me find what my angles shoould be up in the front they always talk about the rear. I guess my question would is the front pinion angle simialer to the rear pinion angle. Any help or addvise i would greatly appreciate it ive been with out my jeep fr about 7 months just due to this one issue and no shop will touch it.

@ATEMOFFROAD 2 года назад

Yes the rules for the rear apply to the front, however you will need to adjust pinion with upper control arms. Also you can easily throw your caster out of wack. So lower control arms are also necessary depending on your lift, lower control arms will push that axle out further allowing to correct caster and pinion angle, pinion angle is always priority over caster . Once you get to 4” or above, caster becomes a real problem. Sometimes if your tj is equipped you can adjust caster at the encentric bolts axle side of the lower control arms. Definitely make sure your drive line is good! Hope that help ! Thanks for watching I appreciate it 🍻

@lannyandroxanneadvantures2546 6 месяцев назад

Do you add more gear oil?

@ATEMOFFROAD 6 месяцев назад

I don’t, but some do add more oil. It’s not necessary as the oil will get to both pinion bearings . If that’s your concern. When you change the pinion angle you do change the fill line and when you go to replace the oil for the first time after, it may seem like the axle housing was over full. It’s not. To refill go by the axle housings oil capacity, rather than going by the bottom of the fill hole, when fluid starts spilling out. .

@desertdog2282 5 месяцев назад

Anything is possible, but with the front axle keep in mind your castor steering angle.

@ATEMOFFROAD 5 месяцев назад

Yes but you will need adjustable upper control arms to adjust this. On an Lp Dana 30 moving the pinion up 4.5 degrees is about the max you would want to go, beyond you loose caster. That changes if you were to swap in an HP 30 wich is mentioned in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tFJ0jYcF3iw.htmlsi=3xxhJebEsvv9sQsA

@adtech247 2 года назад

is the same for the front shaft and pinion?

@ATEMOFFROAD 2 года назад

Yes it’s the same up front but keep in mind you also change caster. The rule of thumb is pinion always before caster. if still out of wack a set of adjustable lower control arm will push that axle out further allowing to make the necessary corrections
