    I have a 14bolt and 203 combination with the stock driveshaft. How should the ends of each driveshaft line up
    to each other? I am just talking about the driveshaft and balance. Hopefully you understand this jibberish /forums/images/graemlins/dunno.gif


    ****UPDATE---Well what i thought was the tsl's rumbling down the road was actually my driveshaft out of phase. I fixed and now SMOOOOOOTH as can be. So nice and thanks to those who answered, easy fix but so good to be able to change radio without missing buttons because of vibes /forums/images/graemlins/woot.gif and oh by the way...the tsls ride great!!!!

    Re: Rear driveshaft question, simple one

    With stock shafts (non CV) they need to be parallel to each other, transfercase and pinion yoke both straight. With a CV shaft you aim the rear pinion at the transfercase. Most driveshaft places online show pics.Try www.4xshaft.com and click on tech info at top of page /forums/images/graemlins/k5.gif

    hmmmm..i knew i wasn't clear. I understand about the pinion and tcase output, but doesn't the shaft have to be installed a certain way..driveshaft yoke to driveshaft yoke? hmmm..hopefully that helps.

    I know what you mean, and I believe you've got them 90 degrees off. BUT, it all depends on how the unit was balanced. If it came to you balanced as you have it in the picture, leave it that way. D-shafts are balanced as one unit.

    the pic is not of mine, just a pic i "heisted" from tom woods. I thought it mattered about the ends lining up...hmmm.....maybe not....

    They do have to line up. This is referred to as, "phase". If both joints aren't in phase it will vibrate your fillings out.

    Re: Rear driveshaft question, simple one

    Is your d-shaft a CV like the one in the pic or is it a regular non CV (only 2 u-joints) shaft? With a non CV shaft they do need to line up...with a CV shaft I don't think it matters (if it does it couldn't be much).

    If you have a non CV shaft and it isn't lined up remember that there will still be 2 different ways that you could line it up. You need to get the right one (the one it was balanced with) to have it vibe free. Might just want to take it in and have it balanced.

    its the non cv type so it is installed wrong. So i have 50/50 chance on this one.
    Thanks for all the help
