Got into the Jeep and it wouldn't move. The axle wasn't moving at all. The driver side was locked and even in 4wd Hi, it wouldn't budge. I could feel the suspension load up and didn't want to push it till something broke. So I borrowed a car.
Jacked the Jeep up the next day and couldn't get the drum off. Opened the bleeder valve and only got the usual dribble. Used a deadblow hammer to knock the drum off and everything looked ok. The drum showed the holes in the shoe so it was on pretty tight.
Here's my guess o what happened; the drum was hot from driving. I applied the e-brake firmly as I usually do. Ad the drum cooled it contracted and basically press-fitted itself to the shoe. Releasing the brake did nothing as the two were now stuck together.
