installing front drive shaft to diff? causing vibration??

is there a certain way to reconnect the drive shaft to the front diff? i just did the fabtech and was required to disconnect the drive shaft from the diff to lower it. was it suppose to go back exactly how it was on when i took it off? i might have spinned the drive shaft a bit before rebolting it, would this cause my vibration?? i get a good vibration at 25mph. also the front cv shafts, how do you know if there pushed it good enough?? one side i torque with a battery impact wrench and im thinking it wasn't strong enough to hit 160lbs and the other side i used a impact gun from a compressor. would this cause anything? i bought some new cotter pins so i could hit that side with a real impact gun.

You are suppose to mark the location of the drive shaft flang relative to the diff's output flang before you remove them so that they go back on the same. Yes they are suppose to go back exactly in the same orientation. That is most likey the cuase of your vibration. Since you do not know how it was orignally mounted your best bet is to reclock the DS and see how it drives. Most DS flanges can be mounted every 90 degrees. Whoever due to cutout in the flang you can notice matching wear marks giving it only 2 possible mounting locations every 180 degrees. I am not sure how the flange of the front DS are set up. If you can jsut flip it 180 you are in luck. IF not, mark the current location and rotate, test, rotate, test...

As for torque, NEVER USE AN IMPACT GUN TO TIGHTEN A BOLT TO TORQUE!!!! There is NO WAY to know what you are tourqing to. The rating on a impact gun is only a generalized range. Hitting a bolt/nut with the impact can apply mucg more tourque then intended. Tightening the bolt with a gun to the end of the thread with the gun setting on low, then tourque to spec with a toruqe wrench. If you do not have a tourque wrench you can get close by knowing what tourque is. For example if you are trying to hit 160. THe units of tourque is typically foot/lbs. Meaning if you have a 1 foot long lever arm (length of wrench) you need to apply 160 lbs of force on the end. If your force is generated by gravity then the lever arm needs to be parallel to the ground. A 2 foot long wrench would only need 80 lbs...

Now i feel alittle better because i know i rotated it. Ill try doing it on my day off. I hope this solves it. I wish they said that in the instructions. Being im an ameture, i didnt know of this. Thanks. Anymore help or thoughts would be good. Is this harming anything?? I drive maybe 2 miles or less to get to work.

Vibration is probably from the steeper U-joint angles caused by the lift.
The steeper the angle, the more a U-joint will vibrate as it spins. Having them in phase will minimize the effect, but won't completely stop it.

So if i drop the lift, vibration will lessin? Hopefully rotating the DS will help.

What lift did you get?? Drop the lift?

The driveline angle is based on the location of the transfer case and the diff. For the front end the diff is fixed, with relation to suspension travle, and is held in place by the cross member. I think I remember you going to a fabtech drop bracket lift. By changing the coil over setting and changing the angle which the a-arms sit will not change the driveline angle, and thus have no effect on driveline based vibrations.

If this is a well established lift, any driveline vibration issues should be already documented.

Area you sure this is not a result of the rear DS?

Wheels and tires are still the number one source of vibrations.
