Service and repair operations for the exhaust muffler insulator and hanger and bracket must start by elevating and supporting the automobile. The service procedure for exhaust system insulators needs individual attention for correct exhaust system support and requires avoidance of oil-based lubricants. Apply lubricant spray to the holes of the exhaust system insulator that will receive the frame hanger and exhaust hanger. Remove the exhaust system insulator (1, 2, or 3) together with any required other insulators. The installation process begins by applying lubricant on the exhaust system insulator holes before putting the exhaust system insulator (1, 2, or 3) onto the frame hanger together with any other necessary insulators before lowering the vehicle.
