2003 Ford F-150 5.4L Lariat 4R70W 2WD need to identify what rear is on this vehicle. The axle code on the driver's door jamb is H9 which tells me this is a limited slip with 3.55 gear ratio. However, is it a 8.8, 9.75, other? The tag on the pumpkin bolt simply provides information about the gear oil to use, i.e. XY -75W90 which has been superceded to 75W140.
Thank you.
Thank you.
