How to service and repair the muffler on Ford Mustang?

Begin the muffler servicing and repair process by placing the vehicle on a hoist with neutral selection while using a suitable jack to support the rear axle. Choke the upper arm-to-differential bolt before removing the shock absorber nut along with bolt for separating rear shock absorbers from the axle housing and disposing of both pieces. You should mount a suitable jack near the rear converter outlet to support it while lowering the rear axle. Take out the flag nuts together with stud and nuts before you disconnect the exhaust pipe assembly from its position on the rear exhaust hanger isolator and then remove both exhaust hanger isolators. When removing the muffler operators should avoid using oil or grease substances on the isolators because these materials cause rubber deterioration. After proper cleaning of the inlet pipe and catalytic converter mating areas the team should install new exhaust fasteners while alternately tightening each catalytic converter-to-inlet pipe nut to manufacturer specifications. The completion of installation requires performing the reverse steps of removal.
