Interesting to note that in previous posts on many of the MAX threads - The B737 manual trim wheel was "marginal" on the classics. They said stab trim was a issue back then and basically never let it get away or your in trouble.

So Boeing have known about it for along time, but chose never to fix it but make it more "marginal" to control on the NG & MAX.
30 years+ to fix, or ground all for 2 years? Guess that's a management call.

Personally ground them if the wheel can not be turned (and Boeing knew) within the envelope.
