• Q: How to replace the muffler on a NEA/NEB dual exhaust system on 2008 GMC Acadia?

  A: In replacing the Muffler on nea/neb dual exhaust system, initially, lift and support the vehicle. Dislodge the exhaust flexible pipe to Muffler nuts and, with an assistant, free-off the rubber insulators from the exhaust underbody hangers (1, 2, and 3). Then, with help from someone else, remove the Muffler assembly from the flexible pipe and vehicle exhaust. To install, position the Muffler assembly on the vehicle and the exhaust flexible pipe with an assistant's help, and then install the rubber insulators on the exhaust underbody hangers (1, 2, and 3). Make sure to tighten exhaust flexible pipe to Muffler nuts 50 n.m (37 lb ft) prior to lowering the vehicle.
