Maybe rusty front end support beams, maybe sagging, don't permit proper alignment, etc?   But....does that affect braking and that noise and vibration?

The only things that I can think of that would make a noise like that are:

A bad tire, with a bulge or a slipped belt. You would only see this by spinning 
the tire while you watch the face of the tread go by. You can't see this from 
the side or by examing the tread wear.  

A rusty spot on a disk, from sitting parked in one position for a long time. If 
you've got a stuck piston in one caliper, then that pad won't retract and the 
disk will tend to rust worse where that pad stays in contact in one place 
when the car is parked a long time. It seems like water (dew) tends to collect 
there and doesn't dry out.
