Important: The installation of the exhaust system hangers is very important, as improperly installed hangers can cause annoying vibrations that can be difficult to diagnose.

The type of hanger used to support the exhaust system on this vehicle is a conventional rubber block. The rubber block is a rigid hanger with a feature that supports the exhaust system in case a rubber block is broken. The rubber mounts allow some exhaust system movement, but not the transfer of noise or vibration into the passenger compartment.
