OK , double checked underneath today,
Found nothing cut, but I need to correct the spacers used
Under tranny mount was 1/2 " spacer and 11/4 spacer under carrier bearing leaving the drive shaft pretty much dead nuts to the carrier with a 1 to 2 degree negative to the diff.
checked the power steering pump it was pretty quiet but I did notice the fan clutch was binding more than on my 04, so thats a good enough excuse to go with electric fans
