I could have sworn my advice to him was simply to "See if you can't fix the vibration first" before plunging into manual hubs. What was wrong with that advice??? I'll continue recommending trying to find the vibrations first before deciding to install manual hubs. If the vibrations persist, great, install manual hubs. If the vibrations were, say, only caused by a bent front driveshaft, then he saved a bunch of coin.
The bottom line is that not all front-end vibrations need manual hubs to cure.
Did you even read what I wrote fully? I already said I understand your intent.
Let me ask you differently. Do you believe, or do you not believe, that there is a very specific harmonic vibration problem in TJs (usually becoming visible in a lifted jeeps with larger tires after a re-gear) for which the only practical solution is a front hub kit?
