My 85 Sonoma was equiped with a rear locker. After a weekend outing, it has now decided to be a spool. It never unlocks and now when making a tight corner on the street, it sounds like a sheer chopping through 3/8 plate 4130. I know one tires is trying to spin faster and all that but what could have gone rotten in the pumpkin for it to not EVER unlock. I know that little 7.5" 10 bolt can only take so much staying locked with 32's before it grenades. I'm gunna pull the cover and take a look.Thanks for any input.
