It’s been a bit since my last update. I came out to go for a drive and found a huge puddle of grease under my right rear tire. What a hot mess getting the hub apart, those cone washers suck to remove. Long story short I replaced the axle oil seal (PN 9031035001) and the hub seal (PN 9031162001), inspected and repacked the wheel bearings and races. I also needed to replace the oil soaked brake shoes. Not a tough job but pretty messy.
As for the root cause of this mess, a plugged axle breather, (PN 9093003097). If you haven’t done so, make sure your axle breather lines both front and back are not plugged. Learn from my mistake, a $7 part cost me hours of work and a bunch of $$$ in parts.
