So I got under the car, there’s nothing wrong, nothing loose, tbh I think it’s the new PowerFlex poly front diff mount making a SHIT LOAD more noise in the cabin. It’s gotta be that plus the fact that I removed the sound deadening. I did also do CMP solid subframe mounts, not sure how much a role those are playing.
I knew I was doing some questionable stuff, and yes I did read all the threads I could find. but I didn’t imagine it would increase the NVH THIS MUCH. I suppose I’ll have to just live with it for a while, until I feel like doing a big pain in the ass job to swap that out, but I feel kind of annoyed at myself for going against the sage advice of the e46 elders and proving them right yet again.
FWIW My old mount was also poly but it was way quieter. I still have the same older poly mounts on the rear of the diff cover. I had to replace the front because I ended up having to replace the entire subframe due to uncovering negligent past repairs, and the old mount couldn’t be saved.
