If it does apply there will be a Lexus-specific bulletin put out.
It would be interesting to see if the target resonance is the same. The Lexus engines are Japanese production, Tundra/Sequoia are US production.
Gen 3 crowd was raging when told the engine is defective by design, "you can't afford having your own opinion for the matter unless own one". With the abusive moderator giving the last warning and threatening to ban. A few years and multiple engine redesigns later engines still die. Most of the raging fanboys, the moderator included, jumped out of Toyota entirely or at least returned to Gen 2. How ironic...
I think the hammer test is actually clever. Undoubtedly it will produce a lot of false positives because of under-educated labor, who don't understand the mechanics of the test. A proper diagnostic rig needs to be self-contained, like a little box bolted to the crank pulley, press the button, watch for green or red light. With variable length waves it can even detect exactly which of the main bearings gone bad. But modern days Toyota is greedier than ever. "Hit it with a hammer".
