I was about to change the drivers side rear tire on my truck ('94 Ranger). I put the parking brake on, chocked the wheels and tried loosening a couple lugs with the short tire iron for the factory jack. They wouldn't budge, so I unchocked, removed the parking brake and tried to set off to the auto parts store for a better iron.
But it wouldn't roll. Seemed like the rear end was locked up-- though I can put it in reverse and roll backwards?!
I set and released the parking brake a few times, no luck. Then I checked the line to the parking brake--- seemed adequately slack when released, and taught when set. So I don't think that's the problem. Also, wouldn't a stuck parking brake prevent the truck from rolling backwards?
Did something seize up in one of the rear drums? It drove fine less than 24 hours ago-- how could wrenching on some lug nuts cause this issue?

suggests the auto-adjusters are the problem. Sound right?
