Is it a true "locker" or a spool?

They are known to make noises on turns depending on the application.

Does it require any certain additives?

that sucks dude. at least mine is just old and worn out.

I've heard that the Auburn's don't last as long as other types. The bad part is I don't think they are rebuildable. You might see if a mod will move this to 'Engine and drivetrain' for more replies and a better idea what's going on.
