when i did mine all three plus the s/c bearing were in the process of failing. its cheaper to replace than repair the damage caused by a seized bearing. since then i have been testing a psk from needswings for the c3 setup. it replces these pulleys with larger pulleys and a longer belt to slow the pulleys down
