Muffler W/Tpipe Insulator

The procedure to change a left adjustable Exhaust Hanger starts by lifting the vehicle then taking off the left rear tire assembly and the left rear inner wheelwell housing. The suitable jack should support the left exhaust Tail Pipe before you remove its insulator. Users should mark the frame next to the Exhaust Hanger bracket before removing rivets retaining the hanger with a grinder followed by gentle prying to detach the hanger. Knock the rivet stems into the frame structure by using either an appropriate hammer or punch. Drilling holes on the frame requires a 7/16 drill bit. Use a paper to transfer frame scribe marks to the new Exhaust Hanger while marking the drill spots and complete the hole drilling process using a 7/16 drill bit. Follow the new Exhaust Hanger installation by fastening the frame with provided hardware while tightening the nut and bolts to 25 nm (18 ft. Lbs.). You should reinstall the Tail Pipe insulator followed by removing the support from the left exhaust Tail Pipe before installing the rear fascia and left rear inner wheelwell housing plus left rear tire assembly. Lower the vehicle after you verify and adjust the necessary settings on the Exhaust Hanger.

Raise the jack supporting the tail pipe and install the nuts to retain the right side exhaust insulator before removing the jack.

Scribe location marks on the frame around the exhaust hanger bracket, then grind off the heads of the rivets retaining the exhaust hanger to the frame.
