Drive line ?\'s Ok this is in an update on I'm a freaking idiot. The salvage yard guy showed me how to take the slip yoke off and turns that is all I had to replace. Still have the same drive shafts only changed the middle yoke. Now went back together with it new u-joints, new tranny, rear tranny bushing, rear tranny seal, and tranny mount. now I have a terrible vibration at 35 to 45mph only. It happens on acceleration and decceleration, both in 3rd and OD, it even does it when I put it in neutral. The question is if I have the drive shaft balanced don't they just balance the shafts? The only thing I changed is the yoke.
