'85 full size rear end problems

[Cynide357]

I almost have my '85 paid off from a friend, and I'm ready to go pick it up.  From what I know, it drives fine in reverse, but when in forward, the right rear wheel won't spin.  It is a 4 wheel drive, by the way.

It won't spin as in the engine can't make the wheel turn. Or it won't turn as in it locked up?

[Cynide357]

Because it is locked up.

If it has sat a while the drum may have rusted up

Welcome to the site from Central California! 

Any noises coming from the rear?

This ^^^^^

Or, might be that one brake is adjusted a little too tight.  Pull the drums to inspect the brakes, clean up the drums if needed, then adjust them on both sides.

I'm going to look at it real close tomorrow.  More updates then.
