Stress-Free Alignment of Exhaust System

Exhaust system, aligning free of stress (all wheel drive vehicles)

Note: Align exhaust system when cold.





^ Remove bolts -1- through -4- and remove crossmember (55 Nm).
^ Vehicles without clamping sleeve between center and rear muffler
^ Loosen double clamp bolts, Refer to Exhaust System, Service and Repair, See item 14.





^ Push exhaust system far enough forward (arrow) so that the pretension at the right retaining loop at center muffler a = 5 to 9 mm.
^ Tighten double clamp bolts uniformly to 40 Nm.
^ Align end pipes.
^ Vehicles with clamping sleeve between center and rear muffler

Note: Only for vehicles with double clamp between center and rear mufflers, the center muffler must also be aligned.

^ Loosen double clamp bolts, Refer to Exhaust System, Service and Repair, See item 14 and -item 24.





^ Push front part of exhaust system far enough forward (arrow) so that the pretension at the retaining loop at center muffler a = 5 to 9 mm.
^ Tighten front double clamp bolts, Refer to Exhaust System, Service and Repair, See -item 14 evenly to 40 Nm.





^ Push rear part of exhaust system far enough forward (arrow) so that the pretension at rear retaining loops at rear muffler a = 7 to 11 mm.
^ Align rear muffler horizontally.
^ Tighten rear double clamp bolts, Refer to Exhaust System, Service and Repair, See -item 24 evenly to 40 Nm.
^ Align end pipes.





Tailpipes, aligning
^ Check distance of end pipes at left and right to bumper:
^ Dimension x left = dimension x right
If necessary, correct dimension x as follows:





^ Loosen nuts (arrows) of brace between exhaust pipes. - Change the distance of the rear mufflers to each other. - Tighten nut to 23 Nm.





^ Check distances -y- and -z- of end pipes to bumper:
^ Dimension y = greater than 20 mm
^ Dimension z = 9 to 14 mm
^ If necessary, check whether the exhaust system is installed free of stress.
