2010 LX, 210k miles. Has anyone had experience replacing subframe mounts or bushings on a 3rd gen?
Using the image below as a reference, I noticed today that #8 (RUBBER, FR. SUB-FRAME MOUNTING(FR) (50260-SHJ-A01)) is completely smashed on one side so that #6/7 (STAY B, L. SUB-FRAME MOUNTING (50238-S0X-A00)) is nearly touching the sub-frame. #8, between the stay and the subframe, is now shaped like a piece of pie instead of a hamburger, with one side nearly flat and the other still thick. The nearly flat side now provides next to no insulation between the metal stay and the subframe and is so flat that I couldn't slide a penny between #8 and the subframe. Additionally, #6/7 is severely warped, so badly in fact that part of it is nearly shaped at a 90-degree angle and is nearly touching the body. (I used the passenger side as a comparison.) My theory is that the smashed #8 and warped #6/7 are providing so little buffer between the subframe, the stay, and the body, that any little flex of the subframe is what is causing the elusive rattle I've been chasing for 1-2 years. My theory is that they were bent/smashed due to road debris or something. The arrow is supposed to show how they go together and get mounted.
Thanks in advance if you have any input. All three parts come to around $60, but I'm undecided if I want to tackle a potential subframe removal repair on my own.

(I found one older thread from 2019 on this topic, but it didn't appear to have a solution, thus this new thread.)
