Honda CRV shakes

My 2002 Honda CRV will sometimes have a terrible shake in the front passenger side wheel and the steering wheel moves back and forth about 2". Fells like the wheel will fall off. It will last 4-5 miles (while I drive 10 MPH) or 1 mile then correct itself. Does it once every two weeks or so, doesn’t matter if cold or warm outside. Tried new tires & new brakes. Help!

I would have the power steering system checked.
