i posted a picture of my pinion angle above.

i want to know if my pinion angle is acceptable for a double cardan. i dont have an angle finder nor am i anywhere near my JK at the moment...i also do not have adjustable rear upper arms.

i would like to avoid having to buy rear upper arms since that would just double the cost of adding an aftermarket driveshaft. so im hoping you guys who do have aftermarlet shafts can eye ball it for.me and tell me what you think.

 

Pics not showing ?
There's a good chance you will need uppers depending on lift height.

 

i posted a link. my phone is giving me a lot of trouble posting a photo. i have a 3" lift on a 4 door.

 

Sorry, chknkatsu, I know this is off topic but how do you like your Dynatrac ball joints? Any issues?

 

zero issues even with hydro assist. but i dont drive my jk often and i also grease them very often. never heard of anyone else having issues with them.

 

Thanks. Planning to go that route when I regear and gusset.

 

Pinion doesn't look bad at all.

 

thanks. i guess the next best way is to just throw a driveshaft on and see

 

Looks to be inline with the driveshaft.

Since the axle rotates back (pinion rotates up) under acceleration, you might see some recommendations to extend the lowers a tad to drop the pinion 1 degree from inline. But should be fine as is.

 

Is the pinion angle supposed to be inline with the drive shaft or the back of the t case. I have a standard drive shaft on my jku with adjustable uppers and lower but have been given advise that the pinion should be inline with the t case. Thanks.
