For the heck of it, i took this video also might as well post it, tires off the ground, right side brake caliper has some drag on it a you can see but can hear the noise coning in an out, wonder if there is something to what @SeanRitchie is saying.
Hopefully Trans guy is going to come over this weekend and listen to it, and then I am pulling it back out again. Tested out one last thing, slowly wound 1st gear out, shift to 2nd, the tone definitely follows engine RPM and not wheelspeed.
