We have a 2004 Ford F150 FX4 4X4 with limited rear differential. I want to replace the rear differential's oil seal which is located next to the flange. I would like to know if there is supposed to be a washer after I have reinstalled the flange be fore the nut is tightened on the pinion. When I removed the old one there was no washer. Also, I would like to know after I have replaced the oil seal and reinstalled the flange how much is the nut supposed to be tightened. I would appreciate your help before I continue to work on our vehicle. Thank you for your help.
