Hi all,

I'm repairing the infamous rusted out rear subframe mount on my 2003, the usual left rear one just in front of the spare.

Where does the hole end up coming through the floor pan in the cabin?

Also, to those that welded - how did you access the front side of the channel? There doesn't seem to be any access there.

Thank you!

Have you seen the ETCG video where he repairs it?

This, from another trusted Piloteer might help, too, if you're undertaking this worthwhile project...

Post some pics of your own, as well, as it advances.

Thank you both for the info.

Has anyone done this without dropping the subframe like ETCG does?

I mocked up an @plplpl style bracket from thin steel and was able to get it in place without removing the subframe.

@plplpl With your repair do you think that the load is going through the legs of the bracket into the two flanges or mostly straight from the face to the unibody channel? Unless it is shimmed the load path is probably one or the other. Does that make sense?

Thanks again for your time.

I cannot rightfully take the credit for this fix. I was merely passing along information from one whose sandals the thongs of which I am not fit to tie.

Truly I tell you, I trust that he who comes after me will save you.

Maybe so, but among those born of women no one has risen greater than you.

My brother helped me to fab my repair bracket today. Will take photos of the repair process in a few weeks when I do the install.

My bracket is 1/4'' steel which is what I had on hand. On mine, some of the vertical load will be carried by shear pins match drilled after installation, rather than the flanges in the drawing. Most of the vertical load will simply be carried by the bracket bottom plate in bending and transferred straight to the existing unibody channel.

All I know about this repair is from watching it develop and hoping I never need that knowledge, but my gut says that you want as much of the load as possible transferred directly into the unibody. A number of people who experienced this failure had previously had rear-side impacts, so there might be weakness to lateral loading in the original design.

I think that an add-on bracket capable of handling that type of load via the legs would be pretty substantial.

I'm also looking forward to pics of your design. Good luck!

Bought the hardware. Plan to machine the holes in my bracket this weekend and pull the 3rd row. I hear that getting those bolts (3rd row) out might be a problem on my rusty Pilot. Any advice is appreciated.

Thanks for all the help.

Watch the video above. He had to use heat from above to get it out.
