I have a 04 F150 FX4 4X4. I believe my front pinion seal is leaking and I hear that "there's all kinds of videos online that will help you to figure out how to replace it." However, the only videos I find are rear pinion seals and non Fords. Can anyone point me in the right direction to find any info on how to replace my own. Like most of us I don't have the money to pay a professional mechanic or a dealership for that matter to do a job that I'm pretty sure I can do. Just need a little guidance here.
