The oblong plug just in front of the rear wheel on each size does provide access to the cavity that forms part of the rear axle support structure. Spraying oil into the oblong plug holes will not actually get oil/rustproofing into the larger inboard cavity. But...there are holes a few inches up into which a short wand could be placed. Possibly even the straw on a spray can of rustproofing could reach. A flexible wand would definitely work better. No matter how you access the inner cavity, I would load it with a very large amount of oil or rustproofing. When my repairs are done, I will be using a flexible wand and blast close to 1/2 a liter or more of stuff in there. I plan to use a thin product so that it will soak through any additional debris and stuff that accumulates in there.

Here is the hole to access the inner cavity.



Another look inside

Great job and great find!
Was telling my friends I feel like scrapping my Yaris because of the holes on the subframe, and they were laughing at me. I have to admit that I'd be spending as much or more time swapping the turbo setup into another Yaris than patching these holes...

I'll be following this closely as I plan on doing this before the winter.
