  Q: How to replace the exhaust hangers on Buick LeSabre?

  A:

  The procedure for exhaust hanger replacement starts by elevating the vehicle with support equipment. The bolt connecting the center exhaust hanger to the rear suspension support bracket must be removed first. Use appropriate lubricant on the exhaust pipe hanger rod before extracting the hanger by pulling at its center point on the rod. After removing the nut that secures the rear exhaust hanger to its bracket you should provide lubricant to the tail pipe hanger rod and then pull the rear exhaust hanger away from the rod. Apply a mixture of soapy solution to both the tail pipe hanger rod and the inner diameter of the rear exhaust hanger before pressing the rear exhaust hanger onto the tail pipe hanger rod and placing it to its proper position on the rear exhaust hanger bracket. When installing the rear exhaust hanger bracket nut to its place, tighten the nut to 30 Nm (22 ft. lbs.). Wash the exhaust pipe hanger rod and inner diameter of the center exhaust hanger with soap before placing the center hanger over the pipe rod for securing using an 30 Nm (22 ft. lbs.) bolt to the rear suspension support bracket.

  Q: How to service the exhaust hangers on Buick LeSabre?

  A:

  Service the exhaust hangers by first raising and supporting the vehicle. Attach a suitable lubricant to the center exhaust hanger bolt which joins it with the rear suspension support bracket. Put a suitable lubricant on the exhaust pipe hanger rod before pulling the center exhaust hanger off the rod by pulling it outward. Begin by removing the nut linking the rear exhaust hanger with the rear exhaust hanger bracket then spray lubricant on the tail pipe hanger rod before pulling the rear exhaust hanger away. Use a soapy solution on both the tail pipe hanger rod and the inner diameter of the rear exhaust hanger to make installation smoother before putting the rear exhaust hanger onto the tail pipe hanger rod and properly positioning at the rear exhaust hanger bracket. Secure the rear exhaust hanger to its bracket by installing a nut which should reach torque specifications of 30 Nm (22 ft. lbs.). Follow these steps to install the center exhaust hanger: apply soapy solution on both the exhaust pipe hanger rod and the inner diameter of the center exhaust hanger, press the center exhaust hanger onto the exhaust pipe hanger rod, tighten the bolt which connects the center exhaust hanger to the rear suspension support bracket to 30 Nm (22 ft. lbs.).
