2010 Chevrolet Tahoe Muffler Parts and Q&A

• Q: How to replace the exhaust muffler on those equipped with LMG, LY2, or LY5 on 2010 Chevrolet Tahoe?

  A: Replacement of an exhaust Muffler starts by elevating and securing vehicles that have lmg, ly2 or ly5 engines. Remove the chassis wiring harness electrical connector from its connection to the right rear wheel speed sensor wiring harness electrical connector. Vehicles with rpo z55 need battery disconnect before separating the right rear Shock Absorber harness connector and air line from the Shock Absorber. Detach the wire harness electrical connector clip from the frame but avoid separating the rear suspension link rod from the position sensor ball stud. Support the sensor lever before you use a twisting motion to detach the link rod ball from its ball stud on the right rear automatic level control sensor. Lift the rear axle with an adjustable jack then disconnect and remove the right axle tie rod bolt and nut and possibly the rear axle vent hose with its swivel clip from the rear brake crossover pipe. First remove right rear stabilizer shaft link to frame bolt and nut followed by right rear stabilizer shaft link from frame as well as right rear Shock Absorber lower bolt and nut. Lower the right side of the rear axle until you can remove the Muffler by loosening its Catalytic Converter to Muffler clamp bolt. The lubrication of Muffler assembly hanger insert points allows for easier removal and with help removing insulators from exhaust system hangers and the resonator insulator while avoiding flex coupler stress. Ive the Muffler assembly off then apply lubrication to the insulators before hanging it. Avoid damaging the Catalytic Converter assembly by providing support to maintain vertical movement below 6 degrees. Install the Muffler assembly and the insulators to the exhaust system hangers under assistance. Screw in the norma clamp bolt connecting the Muffler assembly to the three-way Catalytic Converter with a torque force of 28 nm (21 lb ft). Position the right side of the rear axle before inserting the right rear Shock Absorber lower bolt and nut. Tighten bolt and nut to 95 nm (70 lb ft) and install right rear stabilizer shaft link to frame while securing bolt and nut to 65 nm (48 lb ft). Place the right rear axle tie rod bolt and nut into position and tighten them to a torque of 105 nm (77 lb ft). Additionally, attach and tighten the rear axle vent hose and its swivel clip if needed. Install right rear link rod to ball studs on sensors using tool j 38185 followed by right rear wheel speed sensor wiring harness clips to both frame and Control Arm Bracket then install right rear wheel speed sensor wiring harness electrical connector clip. When vehicle is equipped with rpo z55 the right rear air line should be joined to the Shock Absorber followed by a connection between the chassis wiring harness electrical connector and right rear wheel speed sensor wiring harness electrical connector. Finally, lower the vehicle.
