Well I investigated bubble that I found doing wheel bearing last week. Turns out its not simple surface rust. Its frame rusting through inside. Picture says all. Its not official hole yet but it will be soon.
On the pic you can see area where rust is coming out, surrounding metal is nice and even, rusted metal is all pitted. I painted that spot few times and cleaned but its just keeps coming out. Now short of taking grinder I can not remove rust because its rusted through. I took pictures and will be calling Toyota corp on Monday. But my 2gen officialy had joined my 1gen in crap frame fest..
Also I officialy start 2gen "Frame rusted through" club
