I believe I talked to that guy "Westman". The left front refered to the one
"odd ball" rubber bushing on the engine-support-bar to frame connection.
That has been welded on mine. It helped, but a drone is still present.

I just checked the weld, and it is still solid.

This is driving me crazy...., well driving me drink...,  well driving me to
this list!
