It's should do, as long as that's the only place the vibration is coming from.
If your vibration from the front prop is anything like mine after I fitted the caster correction radius arms, and you've been driving it around for a while, then I'd also check the output bearing from the transfer box. There should be a small amount of movement from the output shaft, just enough to be able to see it.
And don't forget a new seal for transfer box flange as well.
