Me the Drive line doesn’t make a difference how you took it off or put it on? This man works at a huge commercial driveline shop.
Now, immediately after installing drive shafts it was jittery . Has progressively vibrated to the point where you’re literally shaking as you’re going down the road .
A chk eng light reveals IAC valve needs cleaning. I bought what TW suggested and this is my only ride temps in the teens.

 

As far as how the front slide into the transmission and how it bolts to the third member no, it shouldnt make a difference. Was the front half of the drive shaft seperated at the center carrier and reassembled?

 

Yes. Thank you.

 

driveshaft phasing is important if it was separated. This should be day 1 knowledge for any driveline shop though.
