[H. L. Chauvin]

In just reading your replies, & not seeing what you have, it sounds like:

1. When the car does not move, you may have a broken rear axle; and,

2. The hub comes out part of the way which could mean that the hub is loose on the axle, but the rear brake bands are expanded & are tight in the brake drum; hence, will not allow brake drum removal -- try loosening backing plate square headed brake adjustung bolt & releasing emergency brake to see if hub will come off.

Let us know what you find!
