So i am having a problem which feels like my rear is binding up. i rebuilt the entire rear back in 2004 with an eaton posi and all the new bells and whistles possible. when im in a parking lot and making a slow turn the rear feels like its binding. no chirping no normal posi popping no noises back there just stops the car dead. and i have to gas it to finish the turn. did i not put enough posi fluid in it maybe its not slipping enough?? once i get moving the thing is fine. anybody experience this before??
