My first guess is a broken motor mount.

I'd have a look at the drivetrain...specifically axles and CV joints.

Bad CV joint or whatever the drivetrain joint is on that vehicle.

I concur with the CV joint or other drivetrain issue. A motormount =
usually clunks once on acceleration and then once on deceleration.

However being a FWD car, there are forces of drivetrain and wheel =
alignment that co-exist. So it could be a loose alignment item that only =
hits the loose part at 50mph, like a sail flapping in the wind as you =
steer into the wind. This really sounds like a shop needs to look at it.=20=

Does it happen at 50mph in reverse? :-)

Could be engine mount.  Also something severely worn/broken in the 
steering and suspension that allows the wheels to move around when 
they're pulling forward on the suspension members, steering rack, tie 
rod ends, etc.   Possibly a CV.
