Rattling sound on Yaris when A/C is off

As for the rust at the subframe, my advice would be to get some oil or some other thin oil-based substance in there soon. Rust Check "red" in cans would be perfect. I'd literally unload half a can in each side. It may drip out, so putting an oil blanked or something under there might be a good idea. The oblong rubber plugs just outboard of those supports should access the inner cavity. When I am done welding, I plan to drill a hole at the lowest part and install a 1/2" plastic plug. That way I can access the area easily when I do my twice annual rustproofing.

Addition: If you do take out those rubber oblong plugs, you might note that the area is filled with sand and debris. I took the equivalent of about a cup of sand and crap out of each side. This is the 'design flaw in this generation of car (hatch, not sure about the sedans). That stuff in there holds water like a sponge.

Thank you for your help. I have bent the tube away from the body, and now the tube is at a safe distance of ~0.5" or so from the former point of contact.

I am going to remove the oblong rubber plug and spray this product into the body cavity on each side. How does the debris get into the cavity? Would drilling a hole in the lowest part of the cavity automatically make the vehicle fail the provincial inspection?
