It is very rare that two mufflers need to be replaced at the same time, but as luck would have it, the next one fails after a few months. Therefore, the entire exhaust tract is often replaced. We do not insist on doing this, since the individual parts of the vehicle's exhaust system are simply connected to each other. Removing a separate section of the pipe can be done without any particular difficulty.
Tap the faulty muffler with a hammer around the circumference and also on the ends. However, you should not hit too hard.
If a clear sound is heard with each blow, it means that the tin has already become thinner and will soon collapse, especially if it is winter and the road is sprinkled with salt.
Support the vehicle and secure it securely.
If the threaded connection does not give in during dismantling, do not rotate the bolt together with the nut in a circle, but try to break the bolt off (in this case it breaks off). The exception is the threaded connections on the engine exhaust manifold.
Before installation, the threads of the threaded connections of the exhaust tract must be lubricated with copper-containing grease.
When installing, the system must be positioned so that there is no tension.
When installing the exhaust tract parts, all threaded connections are not tightened completely at first.
Hang the exhaust system with suspension supports to the bottom of the vehicle.
All suspension supports must be located at the same distance, otherwise the exhaust tract components must be repositioned.
Tighten all exhaust pipe threads starting from the front.
Note: All exhaust tract parts must be sufficiently clear of the vehicle body.
