Those PowerFlex upper mount "bushings" are a joke. I don't understand how those are supposed to do anything....
Since the upper mount is fluid filled... Has anyone drained the fluid and re-filled the mount with urethane? Keep the OEM design, but make it stiffer?
I don't know about drain and refill, but @AutoCoarsen did a bunch of experimenting with filling the whole air-gapped space in with dampening material. I don't recall what he opted to do to/with the bottom fluid-filled section but his work was otherwise really extensive.

Yeah, I've done the window weld stuff on previous vehicles - always worked really well. But, I've never done it on a fluid filled mount before. Not sure how this mount will react to that. Seems like the fluid filled part would prevent the fill from being very effective.
New mount installed. After getting the upper mount installed the harsh vibrations from the stiffer lower mount are much reduced! I'll probably leave in the black insert on the lower mount. Shifting also felt a lot better and the popping out of 2nd gear seems to be gone. Will need to test that a few more times to be sure. I hope I don't have to do this again in 2028.
Also, Jake from PowerFlex got back to me about the discoloring of the inserts and he said, "It's just pigment leaching from the rubber in the mounts. As long as there aren't any physical defects or deformities in the inserts you are fine to reuse them!".
