Excessive corrosion to suspension arms

This should be of a particular interest to all,
This lower suspension arm was removed today after test along with the other side front.
It's off a 2005 Toyota Avensis 2000 diesel.
This is the 2nd Avensis this month that we've seen.
At 1st glance the arm visually looks fine, but after a bit of finger/thumb pressure it becomes quite clear what lies below the surface rust.
It really goes to show that these Toyota component arms need a bit more attention regardless of age.
One to watch out for lads/lasses
