Hello, I have a 2002 ford ranger 3.0L V6 4wd. I have the 7.5 inch rear differential with 4/10 gears. Fluid is coming out of the front of it between the pinion seal and differential yoke. I recently replaced the pinion seal and looks in good condition. The plastic part on the back of the yoke looks a little worn. But not sure if that is the issue. My pinion gear has some play in it when you take the yoke off but the drive shaft has no play in it at all with everything bolted up. The fluid only comes out between the pinion seal and yoke. I think it might be the pinion race or something to do with the yoke sealing to the back of the diff. Any suggestions or comments would be great!​​​​​​​ I have attached 2 photos and a video of the play in my pinion gear.
