Hello, I just purchased a 2010 Lincoln MKS Ecoboost and I noticed it shows "4A" for the axle code on the door sticker. From my research, it appears that is a 3.07 ratio. Could it really have a 3.07 ratio when all of the SHOs are either 2.77 or 3.16?
Thanks
Brian
Did u pull the code from a truck site or vintage site perhaps?
According to the FSM indentification, no, it's a 2.77 (http://www.nicksmustangranch.com/Service_Manuals/2011/2011_MKS/Resources/Service_Manual/sbh01001.htm#extract_12 (http://www.nicksmustangranch.com/Service_Manuals/2011/2011_MKS/Resources/Service_Manual/sbh01001.htm#extract_12))
great, thanks. I had seen this chart before and I assumed the 4A was the same as 4.
Axle Ratio
1 = 2.77
2 = 3.16
3 = 3.39
4 = 3.07
