I am not attampting to start an argument. That being said, any orig. dual row bearings that are still installed in an engine is failing. The outer seal on the bearing has been sitting in oil for at least 13 years. That rubber seal has become hard and pulled away from the sealing surface. This has allowed grease to be displaced with dirty, inadequate oil. This has resulted in *SOME* degree of metal wear. The amount of wear...... who knows with out taking every one that is left out of the engine and measuring every ball. It is very true that two rows of balls does equal a stronger bearing in respect to breakage. However, do not fool yourself, those seals are compromised and the balls inside are losing metal in larger quantities than the serviceable single row replacements.
