Did the mechanic check the rear subframe? It can be weakened by corrosion. And were the wheel bearings checked/replaced?

Indeed the subframe is full of rust, the mechanic check all the bushing and whell bearings(no noise), but someone did say say that can cause vibration even if don't make noise.

Are all the wheels properly balanced, I had a similar problem a long time ago, the wheel balancing machine was not working properly

Or could have lost some wheel weights. That would be a nice easy fix.

Pot hole damaged tires and or bent rims can also cause this symptom. Some pot hole damaged tires visually show nothing to see but if the belts are dented from impacts then the solution is to replace tires.

Can try rotating the wheels and if a wobbly one lands on the front then you also get steering wheel vibrations when the oscillations setup at speed.

You can try lifting vehicle and spinning tires by hand while watching inside rim edge, sidewalls and tire contact surface for wobbly anomalies, otherwise a pro wheel shop Hunter Road Force test machine or equivalent will definitely pickup wheel issues.
