NOTE- This bulletin applies to federal emissions-certified vehicles (sales
equipped with a 5.9L (sales code EMM) or 8.0L (sales code EWA) engine.
This Bulletin involves inspecting and if necessary replacing the catalytic converter.
NOTE: The Original Design catalytic Converter warranty has been extended to
December 30, 2006. Vehicles that according to warranty records have already
had the catalytic converter replaced with an improved service part have been
excluded from this extended warranty.
The vehicle operator may describe a rattling sound from the underside of the vehicle.
|1.||Verify the vehicle is covered by the Extended Warranty.|
|2.||If the vehicle operator describes a rattling sound from the underside
of the vehicle,
perform the following "thump" test to determine if the catalyst substrate is "loose" or
"rattling" inside the can.
a. Raise the vehicle on a hoist and with the vehicle properly secured, identify a solid
surface on the body of the catalytic converter to strike from the underside. (Note:
Avoid striking a heat shield as the heat shield itself may be rattling). If there is a skid
plate in the way, choose a solid connecting pipe close to the converter body to
b. Strike (thump) the surface identified above using a sharp blow from an appropriate
c. Loose ceramic cores (substrates) in converter shells have a distinct "rafting" sound
when struck by a mallet. The sound is like a masonry brick rattling inside a metal
can. (Note: This rattling sound is NOT a resonant sound that would be consistent
with loose metal to metal exhaust pipe or hanger connections).
d. Other sources of rattle noises, such as loose exhaust connections, muffler parts, or
any other part of the exhaust system, should be eliminated by holding the
connecting pipes and the muffler while thumping the converter. This will isolate
potentially interfering noises.
e. If the results of the inspection are positive, and a "rattling" noise is detected, replace
the catalytic converter.
Parts Required: Use the catalytic converter currently listed in StarParts® for the appropriate vehicle.
1. Replace the catalytic converter. Refer to the service information
TechCONNECT. Reference: Service Info. 11 - Exhaust - Catalytic Converters -

Reimbursable within the provisions of the extended warranty period of 12 months,
