Driveshaft angles with carrier help?

Edited: 1/18/2008 12:29:06 PM by pearldrop

If I picture it more as a one-piece driveshaft it makes more sense. I just take into account the two degree difference from the tranny to the first driveshaft.

Since the angles are all in relation to each other this is how I have it figured:

The tranny to the first driveshaft has an angle of 2 degrees down (5-3)The first driveshaft to the second driveshaft has an angle of 11 degrees up (3+8 )So combining those two angles would be 9 degrees. (which if it were a 1 piece driveshaft would essentially make that the tranny angle that I would want to match)

Now to set the pinion I would want the angles to equal zero.

Since the driveshaft is pointing up eight degrees, wouldn

I NEVER SAID NO VIBE AT ANY HIEGHT, I SAID I HAD NO VIBE AIRED OUT. WHAT I SHOULD'VE SAID WAS AT RIDE HIEGHT TO AIRED OUT NO VIBE! I'M SURE IF I DRIVE 70-80MPH WITH THE BITCH ALL LOCKED UP IT WILL VIBE. THE ONLY TIME I EVER LIFT IT THAT HIGH IS TO LAUNCH OR LOAD MY SEA DOO. SO IN MY CASE ON A DAY TO DAY BASIS I DON'T EXPERIENCE ANY VIBE!

70-80 is key to driving in southern california, haha or else you will be eaten alive on the freeways out here. I have my gmc setup to where i get no driveline vibe at ride height, but when you go to down the carrier bearing starts to vibrate. I know they make a poly carrier bearing which im yet to check out.

So, since the tranny points down three degrees I need to point the pinion up 3 degrees?

And then I zero all the angles by moving the carrier bearing up or down?

Do I not need to worry about pointing the pinion down two degrees from that to keep the needle bearing lubricated?

hte pinion should point up and be parallel w/ the trans. yes you adjust the angles of the shafts by the carrier.
