Response appreciated.
I can see that worn splines might add to general lack of smoothness and added vibration
particularly when off loading the engine. But I am struggling to understand
how it could explain my symptoms. I can see that a resonance and 'chattering'
could present a higher resistance maybe, like a chattering supermarket
trolley wheel, but why only after 40 min or so and why not more frequently and
why in just passive cruise for a fraction of a second? Did you have the exact
same symptoms?
I can easily keep filled up and see if it persists. And then also change fuel type.
