Is this for the Escape in your sig?
Ford actually sells OE NEW axles, so that's what I'd do
Ford and GM are the only companies I know of that actually sell all-NEW OEM CV axles! Everyone else only carries rebooted reground Cardone "reman" (cheaply done and with neoprene boots)
Honda, VW, and Subaru owners have access to Raxles. They make axles for *some* other cars but not all. Raxles uses all-NEW components and seem to actually be rebuilt properly.
Sorry for the rant, but given how lucky you are that you can actually get OE new axles, it's easier to just replace the whole thing
In regards to the grease colors, you can always ask the seller, a Ford dealer, or Ford directly. Does each packet have a separate part number on it?
