This is from the owner's manual
"Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and
is considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water"
This is the recomended fluid should you need it:
"Motorcraft SAE 75W-90 Fuel Efficient High Performance Synthetic Rear Axle Lubricant"
This is from the Sheduled Maintenance Booklet:
Change fluid at 30,000 miles for vehicles with model 4R100, all others inspect fluid.
The owners manual also states to use Motorcraft MERCON V ATF in the transmission. It also refers to a model 4R70/75 E-W transmission. (I assume this is 2 model numbers but I'm not sure).
Hope this helps.
