Here's the story. I bought these gears in the spring. Put 200 miles on them. During that time they whined like crazy. My installer told me to buy another set since he thought they might be bad. He put the second set in and they were noisey too. I had someone else check out the rearend when I had ARP wheel studs installed. He reset the gears and now they are as quiet as can be. I believe now there was absolutely nothing wrong with the gears I'm selling.
I paid $189 plus shipping and am selling them for $135.00 plus shipping.
