This is a noise from the output/behind the tranny. I removed the driveshaft today and the CSB did have a grinding noise which as we all know at higher rpm turns into a squeal. If this doesnt fix the problem, I will look at other solutions. The noise remains hot or cold. I will take a video if the problem isnt fixed with this change out.
