I installed the B&M aluminum differential cover. You will have unhook the sway bar and swing it out of the way for the install, but it does clear the sway bar after the cover is installed. Filled it with regular 80w-90 and 4oz of Lubegard friction modifier. If it chatters, I have another 4oz tube I can add 2 oz at a time until the chattering stops. I'm going to paint the sway bar while I have it off.
