I have the spicer 4.88’s with Yokohama 37’s. I do have a whine after hitting 30mph’s. Had the gears looked at twice and even though they hear the whine there is no issues with the install. Two different installers checked them. Also running Amsoil which is supposed to be the best but we will see...
