REPAIR PROCEDURE

1. Raise the vehicle on a lift.
2. Support the TWC with a transmission jack.
3. Remove the exhaust flange nuts and bolts.
4. Remove the TWC, and discard both gaskets.
5. Place the TWC in a vise.

NOTE: Make sure not to bend the pipe or scratch it excessively.

6. Stuff a shop towel into the exhaust pipe to keep debris out. Use a 90-degree angle grinder with a Scotch-Brite Roloc surface conditioning disc to remove all old gasket material.

 

7. Install the TWC with new gaskets and new nuts. Torque the nuts to 33 N·m (25 lb-ft) and the bolts to 22 N·m (16 lb-ft).

NOTE: It may be necessary to walk the new exhaust gasket onto the primary catalyst, and then lightly tap the gasket into place.

8. Test-drive the vehicle to verify that the squeak is gone.
