Vehicles With Front-Wheel Drive
Exhaust System, Aligning Free of Stress
Align the exhaust system as follows to avoid stresses in the system and prevent the transmission of noise into the body:
NOTE:
- Before assembling the exhaust system, the front exhaust pipes and the catalytic converters must be aligned accurately and secured.
- Loosen all bolted connections on the exhaust system (except exhaust manifold and flange mountings, catalytic converted/intermediate pipe).
- The exhaust system must be aligned when it is cold.
- Keep to the sequence described below.
- The dimensions in the illustrations are approximate.
- Vehicles without clamp between front muffler and rear muffler
- Loosen bolted connections on front clamps between catalytic converters and front muffler.
- Push exhaust system towards front of vehicle -arrow- so that rear mounting of rear muffler is pre-loaded by amount a = 7 ... 9 mm.
- Tighten bolts on front clamps between catalytic converters and front muffler evenly to 40 Nm; installation position.
Aligning tailpipes
- Align tailpipes so that distance -a- is same on both sides.
- At same time, set distance -b- between bumper cut-out and bottom of tailpipes:
- Distance b = 97... 103 mm
- Vehicles with clamp between front muffler and rear muffler
NOTE: It is only necessary to additionally align the front muffler on vehicles with clamp fitted between front muffler and rear muffler.
- Loosen bolted connections on front clamps between catalytic converters and front muffler.
- Loosen bolted connections on rear clamp between front muffler and rear muffler.
- Push exhaust system towards front of vehicle -arrow- so that rear left mounting on front muffler is preloaded by a = 7... 9 mm.
- Tighten bolts on front clamps between catalytic converters and front muffler evenly to 40 Nm; installation position.
- Push rear muffler towards front of vehicle -arrow- so that rear right mounting on rear muffler is preloaded by a = 7 ... 9 mm.
- Tighten bolted connections on rear clamp between front muffler and rear muffler evenly to 40 Nm; installation position.
Aligning tailpipes
- Align tailpipes so that distance -a- is same on both sides.
- At same time, set distance -b- between bumper cut-out and bottom of tailpipes:
