driveline vibrations

[konastinky1234]

ALSO with the 8.8 axle swap i got some vibrations. they happen on and off when accelerating lightly just going up in speed from 25 or 20 up to about 40 which is the fastest i've gone so far. i am guessing i would need a cv and SYE type setup to get rid of this problem, but could it possibly be an alignment issue or something other than driveline? i've never experienced this firsthand so i have no idea what to think it is. thanks guys for any help offered.

U bolts tight?

U bolts tight?

it's a TJ..

check to make sure your driveshaft isn't worn or you need ujoints ect..

[konastinky1234]

just put new ones in when i did this and it was fine before. i'll post a pic of the angle later today so someone can take a look and see if it is a bad one or not. i just don't know what would be bad because i've never experienced it.

adjustable upper control arms ? if not, youll need them

also most likely need sye/sv shaft, 8.8's are offset more then a dana 35 (the diff)

I had vibrations on and off before i got the sye and cv, and then it got really bad after a while. Whenever I would go above around 2k rpms it would feel like the jeep was about to fall apart.... then all of a sudden... my u joint snapped and tore apart my exhaust...
might be that?

how much lift do you have?

im sitting at maybe 1 or 2 inches above stock height if that. but fortunately i figured it out. my lowers weren't compressed all the way that they could've been, so we closed em up fully and it gave us just enough compensation to get rid of all vibes. rides like butter now at all speeds. thank fuckin god. thanks for all the help though guys.
