Progress report. Breaking news update.
I got my front drums back freshly turned and lookin' good! I got them out of the truck and set 'em in the garage. Then I took a nap....no, wait, I took the nap first, then set the drums in the garage. By then it was time to eat so I didn't get much done.
The hydraulic jack wheel hub puller didn't work because the chain couldn't keep the jack in proper alignment. Once a bit of pressure was applied the jack turned sideways. After about an hour of slipping, slideing, cussing, fussing and snatching the chain I gave up and went for help.
A friend, who happened to be a real mechanic, drowned the splines with liquid wrench, and tapped the hub on alternate sides for a few minutes and it popped loose. I told him that I was just about to do that myself anyway.
