Chrysler Full-Size Trucks 1997-2000 Repair Guide



Safety glasses should be worn at all times when working on or near the exhaust system. Older exhaust systems will almost always be covered with loose rust particles which will become airborne when disturbed. These particles are more than a nuisance-they could injure your eyes.

When working on the exhaust system always keep the following in mind:

Check the complete exhaust system for open seams, holes loose connections, or other deterioration which could permit exhaust fumes to seep into the passenger compartment.
The exhaust system may be supported by free-hanging rubber mounts which permit some movement of the exhaust system, but block the transfer of noise and vibration into the passenger compartment. Do NOT replace rubber mounts with solid ones.
Before removing any component of the exhaust system, ALWAYS squirt a penetrating lubricant or rust dissolving agent onto the fasteners for ease of removal. A lot of knuckle skin will be saved by following this rule.

Because some penetrating fluids are flammable, NEVER use them on a hot exhaust system or near an open flame.

Annoying rattles and noise vibrations in the exhaust system are usually caused by misalignment of the parts. When aligning the system, leave mounting hardware loose until all parts are properly aligned, then tighten, working from front to rear.
When installing exhaust system parts, make sure there is enough clearance between the hot exhaust system components and other pipes and hoses that would be adversely affected by excessive heat. Also make sure there is adequate clearance from the floor pan to avoid possible overheating of the floor.
