Walnut Grove MN USA | I wonder if it had the proper addative in the oil. Dad had a '79 chevy that tossed the posi and it didn't pull alot either. Ford probably has the toughest rear of all of them. Posi's aren't much different than a clutch in front of a manual trans, just clutches under spring pressure and the more turning you do under good traction conditions like dry pavement the more they will wear. | |
