Front drive shaft Vib / Carrier bearing

Installed 1.5 inch AAL W/ 1.5 inch front lift using 3/4 inch In-coil spacer and 1/4 inch top spacer. Truck only sets up 1.5 - 2 inches higher both front and rear. Now can feel slight vib around 20mph. Appears need to decrease angle of carrier bearing to make more straight. Droping it would increase angle. Q. can you rotate the bearing 180 degrees and make it shorter? Q2 Will Toyota fix the vib even tho I modified the rear and front. It is 2 yrs old and has 20K on it. Q3 What is an easy and cheap fix. worried about damaging u-bolt and joint. Again only a slight vib around 20mph.

Sorry all found a trend on the subject. Also the angle I was talking about was at the transmission - ujoint to small front shaft looked angled to much. Thought by adding shim/spacer to carrier bearing would increase vibe. A little confussed over what to do to the carrier bearing.
