Many elements can cause a car muffler to need replacement. How quickly it is required can depend on the climate where you live, running over something on the road, or many other reasons. The first indication might be the noise you hear when the car is running. The damage may be from an accumulation of debris from the engine oil particles or rust on the interior of the muffler. Replacement processes are not that difficult if you have the right tools and time to fix the problem.

The Right Tools

Prepare to replace the muffler before you have the car up in the air by having all of the tools handy. It will be essential to have a car jack and jack stands to place under the car while you are repairing the muffler to ensure it doesn't fall.

However, many individuals don't trust jack stands and use cinderblocks or blocks of wood. If you have some spare tires around the garage (ones still on the wheels), you could place them under the frame of the car. Place the chosen prop under the rear and front wheels.

You will need some type of saw or cutting tool, wrenches, and a hammer to remove the old muffler from the car. You will also need some type of penetrating oil, muffler sealant, and exhaust clamps to finish the job. For safety reasons, you should have some gloves and glasses because this is a messy process.

The Procedure

The car should be parked on a flat and level surface such as a driveway or garage before you begin. Be sure the car is secure and in the park position with the emergency brake applied. Use the blocks, wood or jacks to support the rear of the vehicle. Use the same procedure on the front of the car, and be sure it doesn't roll. Make sure it is secure before you proceed to remove the jacks.

For a clamped muffler, spray the clamps and nuts with the lubricant spray. Wait a few minutes and use a socket wrench to loosen the clamps that hold the muffler in place. The rust might make the process difficult, but you will be able to separate the exhaust pipe at the front and back from the muffler.

It will be necessary to use a saw to cut the exhaust pipe from the muffler. To replace the muffler, use the reverse process being sure you have smoothed both ends of the exhaust pipe before you place the new muffler on the car. Start the vehicle to be sure it appears to be tightly clamped.

The process is easily accomplished by following these guidelines. Take a test ride to be sure the car sounds like it is noise free. If you were successful, the time and money saved will be worth the effort. Contact a mechanic for help with this issue.
