How to service the muffler on a 3.8L engine on Ford Mustang?

The first step to maintain a 3.8L muffler requires safely supporting the elevated vehicle. The service requires a proper jack to stabilize the rear axle before you remove the upper arm-to-differential bolt. You must disconnect the rear shock absorbers from the axle housing by taking out the nut and bolt then discarding this nut. Start with lowering the rear axle before removing the dual converter assembly flange nuts. The exhaust pipe assembly should be detached from the rear exhaust hanger insulator then exhaust hanger insulators and the muffler need to be removed. Using oil or grease-based lubricants should be avoided because they will deteriorate rubber components of the insulators. Installation of exhaust hanger insulators becomes simpler by using a mixture of soap with water. The end of the installation process involves following the steps used to remove the components backward.

How to service and repair the muffler and tailpipe on Ford Ranger?

One should start the muffler and tailpipe service and repair by putting the vehicle into neutral gear and hoisting it up. You need to eliminate the 2.3L engine exhaust downpipe-to-muffler bolts and nuts alongside the 3.0L and 4.0L engine catalytic converter-to-muffler bolts and nuts. Complete the process by taking off the three rubber isolators then extract the combination of muffler and tailpipe from the vehicle assembly. Designate the front section of installation as the starting point to ensure you only tighten exhaust system fasteners after all components are prepared and properly positioned throughout the repair process. The use of oil or grease-based lubricants should be avoided on isolators because they cause rubber deterioration which leads to separation from the exhaust hanger bracket. Clean up the exhaust downpipe or catalytic converter mating surface and the muffler and tailpipe assembly surface while making sure to avoid any damage to these parts. Place the muffler with tailpipe architecture into the vehicle while connecting its three rubber components. Use the exhaust downpipe-to-muffler and tailpipe assembly gasket then mount the corresponding bolts and nuts with loose tension. Install the catalytic converter-to-muffler and tailpipe assembly gasket simultaneously with the loosely installed bolts and nuts that belong to this section on 3.0L and 4.0L engines. To guarantee proper fitment of the exhaust system it needs to be aligned at the end.
