94 ranger with 9"

[Seven3_AH]

Hello all, I'm wondering what ujoiny I need to use to make a 1 price aluminum driveshaft to a 9" out of a 76 eb
The moog part number for the u joint I found for the 9" is #280 and the aluminum is #270, both moog p/n.

Now the reason I'm doing this is because every time I put a new u joint in my stock 2 piece it snaps 10 miles down the road, I think my opinion angle is off to much or I have a negative angle on the pinion and driveshaft

Any help with this would be wonderful

Are you sure you don't have a bent drive shaft? That would do that.

2 different drive shafts, my pinion angle make a c shape out of the driveshaft rather than a Z kinda shape if you know what I mean

Top pic is what it is right now, bottom is what I think it needs to be (angles sent exact just a representation of the angle it's at)

===================
So you have a narrowed 9" in your 94 Ranger?

What's your pinion angle with it sitting on the ground?

I'm thinking bent driveshaft too, cause if the pinion angle was off that bad either way, it's either gonna spit it out or bust the tailshaft housing.

I set the pinion angle at 0* on my 94 with narrowed Expo 8.8.

It's not a narrowed 9" it came from a 76 early bronco

I'll have to get back to you about angle sitting on ground.. I know it tilts up quite a bit since I put the belltech 6400 shackles on it

And it makes the angle in a frown shape at the pinion like in the first picture above

Your pinion centerline needs to be parallel to the tranny output shaft centerline. You are having problems because of that so you need to fix it. If you put a stronger u-joint in then something else will break, and that thing will likely be more expensive. Here's a link to a Ford pdf driveshaft recommendations;
