Just like you said Scott, it pulled right out. Inside there is a lock nut that looks like I can remove with a spanner wrench, or maybe a drift punch. I did not go any further, as I am doing this outside in the driveway, and they are talking chances of rain for the next two days. Right now, I put the cap back on (less the axle) to contain the rear end grease. Thursday, or Friday when the weather improves I will continue.
In the mean time, I will get my brake shoes relined, and kits ordered for the wheel cylinders. Is it safe to assume that when I remove that lock nut, the wheel hub will pull off like a front wheel hub? Then I can drive out the axle seal, and hopefully match up the numbers at NAPA.
