Removal and Installation

NOTICE: The exhaust hanger isolators are constructed from a special material. Use only the correct specification exhaust hanger isolators or damage to the exhaust system may occur.

NOTICE: Do not use oil or grease-based lubricants on the insulators. They may cause deterioration of the rubber.

NOTICE: Oil or grease-based lubricants on the insulators may cause the exhaust hanger insulator to separate from the exhaust hanger bracket during vehicle operation.

NOTE: Check the exhaust hanger isolators for damage and fatigue. Install new exhaust hanger isolators as required.
