A rattling noise may be heard from under the vehicle. This may be caused by a loose catalyst insulator. Follow the repair procedures in this bulletin to correct this condition.
Do not raise the entire edge of the insulator at one time. Work in sections (complete steps 1 through 3 of this procedure for each section).
