Ford 9.75
Ford 9.75 is a front carrier category under Differentials. Every unit here is a remanufactured front carrier assembly with a 9.75 inch ring gear, and all of the applications are Expedition and Navigator. Open and posi limited slip versions are listed as separate products.
What fits what
Expedition on its own: 2005 in 3.31 and in 3.73; 2003-2005 in 3.73 and in 3.73 posi; 2005 in 3.31 posi; 2004-2010 in 3.31 posi; 2007-2010 in 3.31, in 3.73 and in 3.73 posi; and 2015-2017 in 3.31 open and 3.31 posi. Expedition and Navigator together: 2015-2017 in 3.73 open and 3.73 posi. Navigator on its own: 2015-2017 in 4.10 open and 4.10 posi. The Navigator listings are also grouped on the Lincoln brand page.
How to identify yours
The gear ratios in this category are 3.31, 3.73 and 4.10, and the ring gear diameter is 9.75 on every listing, so the ratio alone will not always get you to the right part. Use the vendor SKU. The RAA440-1383 group covers the 2003-2005 Expedition carriers: 1383A and 1383D are 3.31, 1383B and 1383C are 3.73, and the -P versions of each are the posi limited slip units. RAA440-135A is the 3.31 and RAA440-135B the 3.73 for 2007-2010, again with -P posi versions. RAA440-1534C and RAA440-1534C-P are the 2015-2017 Expedition and Navigator 3.73 units. Across this category a -P suffix is the posi version and the plain SKU is open.
Two things to watch. Several 2005 Expedition 3.31 listings are separated only by their vendor SKU, so quote the SKU rather than the year when you call. And the titles read IFS while the application notes on the 2015-2017 Navigator and Expedition listings read IRS. We list those as the supplier supplies them and do not change them, so confirm the part by SKU and ratio rather than by that abbreviation.
