- The exhaust system hangers minimize noise transfer. Vibration
and noise can be transmitted into the vehicle under the following conditions:
| • | System contact with the body |
- Position the clamps and
the insulator so that the hanger is vertical when the exhaust system is at
operating temperature or 10 mm (3/8 in) forward at room temperature.
- Inspect that the brackets are horizontal.
- Use heat in front of the rear suspension, in order to reposition
the pipes if necessary.
- Allow pipes to cool before touching them.
- Do not use an acetylene torch near the fuel tank.
- Inspect that the support brackets are horizontal.
- Inspect that the clearance between the frame members and the floor
pan is a minimum of 35 mm (1.5 in) after the following procedures:
- Tighten all clamps according to the specified torques. Refer to
Fastener Tightening Specifications
.
- Clearance is needed in order to avoid the following conditions:
| • | Overheating of the floor pan |
| • | Damage to the passenger compartment carpet |
- Inspect that the weight of the system is evenly distributed according
to the equal deflection at each hanger on the following components:
Important: Some vehicles may exhibit exhaust system misalignment due to an improper
installation process of the front pipe. The front pipe, which when installed
low in the assembly, can pull the exhaust system forward and hit part
of the body, or close enough such that when the vehicle goes over a bump
it will contact the body.
- In order to properly correct the condition, reinstall the rear
pipe. Refer to
Exhaust System Description
. The exhaust system should move into proper alignment.
- Ensure that the exhaust system has the proper clearances.
