How to Maintain the Muffler on a 3.7L/4.7L Engine on Jeep Commander?

The muffler can be serviced on a 3.7L/4.7L engine by lifting the car, using the side rails to hold up the rear and making sure the axle is free. Lubricate all bolts and nuts with heat valve grease and leave them alone for 5 minutes so the grease can penetrate. Slide a jackstand under the rear axle, then take off the RH rear shock as well as the RH side of the stabilizer bar. After that, take out the front exhaust pipe/catalytic converter from the assembly flange nuts and remove the ground strap. Remove the tailpipe/muffler assembly from the isolators and remove the assembly from the vehicle. First, set the muffler and tailpipe combo into position and then put in the insulators. Factory-set the spacing between components to not less than 25 mm (1 inch) by making sure the bolts and nuts for the front exhaust pipe/catalytic converter flange are appropriately secured. Put the nuts on until you reach 47 Nm (35 ft. lbs.), then replace the RH shock absorber and stabilizer bar. Let the car down and turn on the engine to look for any leaks from the exhaust system, making the fixes you need.
