Ranger 4WD V6-3.0L VIN U (1997)
Catalyst Shield: Testing and Inspection
NOTE: At idle or during normal driving conditions, a buzz or rattle may be detected, which can be traced to the exhaust system. The heat shield
attachment to the muffler or catalytic converter may come free. The loose shield will vibrate off the muffler or catalytic converter and cause the buzz or
rattle.
