Rattles in the exhaust system can be caused by loose bolts in the three bolt flange connection.
This concerns the following VINs:
95 HN 151297 to 95 HN 152794
If this condition is found, replace the bolts and nuts with the following parts:
Hex Bolt
900 074 267 02
(three required)
Lock Nut
999 084 051 02
(three required)
Tighten these bolts uniformly in several steps to a torque of 10+1 N-M (7+.7 ft. lbs.).
New type bolt heads are marked with an "H" or are blank.
