Are you saying you put it back exactly the way it was when you found it when the tail end was too high ?took lowering blocks out, vibration still there
didn't reinstall helpers so it still sits a little lower, I find it hard to believe it is off now but vibration is still same so I guess it isAre you saying you put it back exactly the way it was when you found it when the tail end was too high ?
I see you said it had helper springs which would have been added and you put them back in ?
Got any pictures of your trans. mount ?
More pictures the better of all mounts.
everything is good with u joints, the vibration is the same as with the old driveshaftAppears you are taking measurements and running it on jack stands that are on the chassis and not the rear end.
I would put jack stands under rear end and front k-member or control arms and re-check angles as it sits when driven.
It may have been mentioned but are the u-joints very smooth to rotate?
Many times after replacement and install of retaining clips you need to tap the caps back out so they aren't binding on the center cross.
Also, of course make sure they are the right size/tight fitment and proper clips to tightly locate it in the yoke.
will try the appFirst, does it vibrate when in neutral, or park? If so, you're looking in the wrong place.
If it does not vibrate in park, as was already said, download the tremec app. I used it on my truck, and it worked awesome.
Unless the car was seriously screwed with, the trans angle should be fine.
The yokes have to be perfectly inline on a driveshaft, not something you can change without cutting the yokes off but it will cause major problems. Watch the video that I posted below, phasing it's at the end of the video.What do you mean by "phased correctly"? Flip it 180 in the pinion yoke I am guessing? I have never heard anybody having to do that with a balanced driveshaft.
