Exhaust System: Adjustments

A misaligned exhaust system is usually indicated by vibration, grounding, rattling or binding of system components. Often the associated noise is hard to distinguish from other chassis noises. Look for broken or loose clamps and brackets. Replace or tighten as necessary. It is important that exhaust clearances and alignment be maintained.

Perform the following procedures to align the system:
1. Loosen the retaining hardware, clamp and the pipe support brackets.
2. Align the exhaust system, beginning at the front of the vehicle, to establish maximum clearance.
3. Tighten all retainers to specification.

NOTE: Tighten the flange nuts and the exhaust manifold nuts evenly and alternately.

4. Start the engine and check the exhaust system for leaks.

NOTE: Three way catalytic converters (TWC), exhaust inlet pipes, mufflers, brackets, clamps and insulators should be replaced if they are worn or badly corroded. Do not attempt to service these parts.
