[QUOTE="Jeffksf B, post: 1017376, member: 65145"] I've used Valvoline synthetic as well and have always added the Motorcraft LS additive. The one time I used an additive from Autozone it made noise. Added the Motorcraft stuff and noise went away. The front diff doesn't have a limited slip Diff so no additive needed up front. The motorcraft stuff is only $6 or $7 bucks at a dealership. [/QUOTE]
