  Q: How to Service and Repair the Exhaust Hanger and System Insulator on Buick Lucerne?

  A: The first step in servicing and repairing the exhaust system insulator along with hanger and bracket requires you to raise and support the vehicle. The exhaust hanger connecting the rear suspension support bracket requires the removal of its bolt so you can apply a lubricant to the hanger rod for successful extraction. You should first pull on the exhaust hanger to disconnect it from the exhaust pipe hanger rod before removing its hanger bracket nut (a single exhaust system uses this method with dual exhaust requires similar steps). You can make the rear hanger rod easier to remove by applying lubricant then detach the rear exhaust hanger from the tail pipe hanger rod by pulling it outward. Begin installation by apply soapy solution to the back hanger rod and inner diameter of the rear exhaust hanger then press the hanger over the tail pipe rod before positioning onto the hanger bracket (single exhaust shown, dual exhaust similar). The rear exhaust hanger bracket requires installation by attaching it to hanger bracket nut before torquing the nut to 30 N.m (22 lb ft). Use a soapy solution to lubricate all needed surfaces of the exhaust pipe hanger rod and center exhaust hanger inner diameter. After that position exhaust hanger onto exhaust pipe hanger rod and fasten it to the rear suspension support bracket bolt with 30 N.m (22 lb ft) torque before lowering the vehicle.
