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.NOTE: Muffler/resonator assembly, exhaust inlet pipe/Warm-up Three Way Catalytic Converter (WU-TWC), exhaust system flex tube, brackets, clamps, and rubber hangers should be replaced if they are worn or become badly corroded. Do not attempt to service these parts.
Perform the following procedures to align the system.
1. Loosen the attaching hardware, clamps, and the support brackets.
2. Align the exhaust system, beginning at the front of the vehicle, to establish maximum clearance.
3. Tighten all attachments.
NOTE: Tighten the flange nuts and the exhaust manifold nuts evenly and alternately.
4. Start the engine and check the exhaust system for leaks.
