First I did the trans insert, shifter bushing and diff bushings. Then a couple months later I did the subframe. At first the NVH from the first 3 was noticeable but I felt like they broke in after a week or two. Either that or I got used to them. The subframe NVH hasn't really gone away, and you may be right. It may be a compound effect.
