A commonly reported reason for vibrations is the trans mounting. If you have polyurethane ones, go back to stock rubber ones.
There have been some reports of "The Beast" sunshell causing vibrations; this will only occur in 3rd gear. (Also in 1st, but no one notices that.) The only solution to that is to have the trans rebuilt to use the Sonnax Smart Shell.
Obviously the drive shaft and u-joints have to be considered too.
