I'm doing re-doing brakes on all 4 wheels ('39) and did the driver rear first. No real issues other than the grease seal was a bear to initially seat properly. What is the trick? I tried a wooden block to get it going down in the hub, but is kept rocking back and forth. Maybe I'm too tentative with it? (Anyway, once it did, I used Supereal's tip of a PVC coupler to drive it down pass the ring lock groove...good trick). Now on to the passenger rear excpet while I was pulling the new emergency cable around, it apparently popped out of the emergency brake arm on the driver side, so I decided to do both rears at the same time. I pumped the driver side rear axle back up resting on an old milk crate (same as the current passenger side) and that was when the mystery started...both spindles rotated even though it was in gear...any gear...didn't matter! Well, now my hub puller can't pull the drum off the driver rear, so I put the tire back on to call it a day and lo and behold the passenger side doesn't rotate anymore! So, why does lifting the driver side axle allow both spindles to rotate?

Parrish, your differential spider gear will turn the rear wheels in opposite direction when one is spun while the transmission is in gear. Later, that wheel resisted turning more than did the driveshaft while the transmission was out of gear, so the driveshaft turned instead of the opposite wheel. Alan

hmmm...not sure I get it: trans in gear; passenger hub already pulled when driver tire on ground and hub puller worked fine as shaft would not rotate, no problem; now both sides off ground and both driver shaft and passenger shaft rotate, still in gear and hub puller not effective as shaft rotates...is that normal spider gear operation? thanks!

See Alan's explanation. Be sure you have the brake shoes fully backed off before you try to remove the hub/drum. If the drum rotates as you are trying to cinch down the puller screw, just put a pry bar or similar tool between the lug nut studs to hold it in place while you wrench down the puller. The parking brake cables often come out of the groove in the arm when the cable is loose, and can just be reattached. If the cable is a bit kinked when it is loose. you can keep the end in place with a small piece of string or fish line before you replace the hub. I often replace the rubber boots on the cable while I have the hub off. It helps to keep enough tension on the cable to hold it in the groove.

Parrish, another way to do this is to reinstall the wheel & tire. Lower the axle to allow the wheel to touch the ground. No weight on the tire, just for friction against the ground. you can now turn the nut, and your drum will pop free. Alan
