ISSUE
Some 2005-2008 Mustang vehicles, built before 12/3/2007, may exhibit a concern with rattle/buzz/vibration from either the center stack (radio/heater)
console, steering wheel, seat, floorpan, and/or gearshift area.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
The rattle/buzz/vibration may be caused by one or both of the exhaust hanger isolators on the transmission cross member number 3 being loose in the
bracket and/or compressed by misaligned exhaust hanger rod. If the voids in the isolator are compressed by the exhaust hanger rod, then it may allow the
hanger rod to ground through the number 3 transmission cross member exhaust mount bracket (Figure 1). Follow the Service Procedure steps to correct
the condition.
NOTE
V6 VEHICLES MAY HAVE THE RATTLE/VIBRATION AT APPROXIMATELY 850 RPM AND 1500 RPM; THE V8 AT APPROXIMATELY
1200 RPM AND 3200 RPM.
NOTE
REFER TO TSB 05-08-06 FOR 2005 4.0L AUTOMATIC TRANS VEHICLES EXHIBITING VIBRATION/DRONE CONCERNS.
