The kit I bought was the installation kit + bearing kit for 89.99. On the same exact kit, there was ANOTHER drop down box for "2010+ bearing" so I called them and asked them what was going on and if I needed to pay 89.99 install/bearing kit PLUS another 59.99 for the 2010+ bearing. The representative Duncan said I was good to go and that the correct bearing was included in that kit for 89.99 without needing to buy the drop down bearing. This is the kit I bought- Rear End Installation and Bearing Kit (8.8in) R8.8RMK - Free Shipping!
Notice how they charge you 59.99 for the bearing, and 29.99 for the install kit. I asked if I had to check the drop down box for the 2010+ bearing, he said no, the bearing included in this base kit was the correct one for my 2011 v6.
I swear that if the bearing is causing these decel vibrations and whine, AM is going to have a HUGE S***STORM on their hands and will be paying for the labor to fix it as well as my gear kit for this false information.
