Q: How to service the exhaust hangers and ensure the support of the exhaust system on GMC Canyon?
A: The first step is to safely raise and support the vehicle while using protective goggles and gloves during service to exhaust hangers and support of the exhaust system. The entire process must avoid the use of oil-based lubrication. A solution of soap becomes essential for hanger removal since it should be applied to both the frame support bracket rod and the exhaust pipe hanger rod . Remove the exhaust pipe hanger gently from each of the frame support bracket rod and exhaust pipe hanger rod . The installation needs a soapy solution on the frame support bracket rod and exhaust pipe hanger and exhaust pipe hanger rod surfaces to make the procedure smoother. Lower the vehicle while directing the exhaust pipe hanger onto the frame support bracket rod and also the exhaust pipe hanger rod simultaneously.
Q: How to service and repair the Exhaust Hanger on GMC Envoy?
A: Service and repair operations for Exhaust Pipe/muffler hangers start with raising the vehicle. Start by disconnecting the heated Oxygen Sensor (H2OS) electrical connector before removing both nuts that hold the Catalytic Converter pipe to the Exhaust Manifold. Discard the old exhaust seal because it should not be used again. To begin the process remove the nuts holding the muffler to the Catalytic Converter pipe followed by the hanger bolt which attaches to the transmission mount then unfasten the transmission mount itself. Remove the Catalytic Converter assembly with next the Exhaust Hanger from the vehicle while separating the Exhaust Hanger from the converter. First put on the Exhaust Hanger to the Catalytic Converter before reinstalling the converter and hanger assembly into the vehicle. Begin by attaching the bolt which anchors the Catalytic Converter pipe hanger to the transmission mount, finish installation by tightening the bolt to 30 nm (22 ft. Lbs.), then put on the transmission mount. Use a new exhaust seal between the Exhaust Manifold and Catalytic Converter pipe before evenly applying nut torque against the exhaust flange until secure and finally tightening the nuts to 50 nm (37 ft. Lbs.). Finish the repair by connecting the h2os electrical connector followed by putting the vehicle into its normal position.
Q: How to Service and Repair the Exhaust Hanger, Muffler Insulator, and Bracket on GMC Yukon?
A: The maintenance of an exhaust muffler insulator, hanger and bracket requires first lifting and supporting your vehicle. Protective goggles as well as gloves are essential equipment for safety purposes. The service of exhaust system insulators must be done one at a time to preserve exhaust system support while keeping oil-based lubricants out of use. Apply spray lubricant to the exhaust system insulators at the connection points with the frame hangers to improve their removal process. Start by taking out Exhaust Pipe insulators (1 and 2) while keeping the exhaust system in position with an adjustable jack (when replacing exhaust muffler insulators (3 and 4)). Afterwards detach the exhaust system insulators (3 and 4) which are installed on the frame hangers. The hanger area requires lubricant application before placing insulators on it. Begin installation of the Exhaust Pipe insulators (1 and 2) to the frame hangers followed by the exhaust muffler insulators (3 and 4) to the frame hangers and muffler pipe. After this end the adjustable jack stand. An exhaustive check should determine that the exhaust system maintains its correct position and space requirements.
