1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Vehicle Jacking and Lifting.

2. Loosen all fasteners joining the exhaust system components.

3. Beginning at the front of the vehicle, align the exhaust system to establish the maximum clearance.

Vehicles with 2.3L engine

4. Position the exhaust downpipe to the exhaust manifold and loosely tighten the exhaust downpipe-to-exhaust manifold nuts to stiffen the joint.





Vehicles with 4.0L engine

5. NOTE: RH side shown, LH side similar.

Position the exhaust Y-pipe assembly to the exhaust manifold and loosely tighten the exhaust Y-pipe assembly-to-exhaust manifold nuts to stiffen the joint.
