Repair And Fix it

The exhaust system in your vehicle is attached at various points along the vehicles frame. The system uses an assortment of clamps and hangers to support the exhaust components, as well as to isolate them from excessive vibration. A failure of any of the clamps or hangers will result in the movement of the exhaust system, which will be felt by the driver as vibration. This can often be heard as buzzing noise from underneath the car.

Instructions

1

Lift the vehicle with the jack and place it on the jack stands.

2

Inspect the exhaust hangers and clamps. Look for any cracking or looseness.

3

Tighten any loose clamps or hangers by turning the mounting bolts clockwise with the wrench.

4

Replace any clamps or hangers that appear damaged in any way.

5

Raise the vehicle from the jack stands and remove them. Lower the vehicle to the ground.

A vehicles brake system is composed of many parts, such as calipers, discs and brake pads. When any one of these parts is out of alignment, vibrations, rusting and ultimately large amounts of friction force can cause noise that is often described as "squealing." Brake systems can be diagnosed and fixed at home without a necessary visit to the mechanic if the vehicle owner knows what to check. Some common solutions include brake pad replacement or lubrication.

Instructions

1

Drive your car for a few miles every day. Moisture from environmental precipitation can rest upon brake systems, causing small amounts of rust to form on the discs. Using the brakes on a daily basis will help wear this rust away and keep the brake system noise-free.

2

Change the brake pads, which are made to become thinner over prolonged use. Thin brake pads will give off a metal scraping sound, which is an indication they need to be changed. Choose brake pads made out of non-asbestos material to remove risks of inhaling cancerous contaminants.

3

Spray a can of aerosol brake lubricant onto your brake pad system to reduce fiction between the brake pad and the brake caliper. Spray this lubricant only on the side of the brake pad and disc facing away from the tire. Apply brake grease manually in the same manner.

4

Clean out the dust within the brake drum. Remove the drum, and wipe the dust away with a spray cleaner and towel. Allow the drum to dry completely before replacing.

Loud exhaust systems can result in tickets in many states. They can also be an annoyance to yourself and others. Your exhaust system could be loud either because of alterations intended to increase the vehicles performance, or because of failing equipment. Regardless of the reason, there are permanent as well as temporary ways to quiet an excessively loud exhaust system.

Instructions

Permanent Fix

1

Make sure the catalytic converters and the mufflers are working properly. If they become damaged or have been bored out to increase performance, they can be very loud. In most cases, the check engine light will be on if the muffler or catalytic converter are damaged or altered.

2

Change the mufflers. On most vehicles there are four bolts which hold the muffler onto the tail pipe. If you have dual exhaust, there will be two mufflers. Glass pack mufflers tend to be very loud, but also tend to allow the best airflow. Reactive mufflers are included on most vehicles and are much quieter. Changing your muffler to a quieter one might affect your performance, but can make your vehicle quieter.

3

Replace your tail pipes. Larger diameter tailpipes tend to be louder than smaller diameter tailpipes. Often larger tailpipes are added to increase performance. If you dont want to reduce your tailpipe size, consider a crossover tailpipe. A crossover lets air travel between two exhaust pipes, which causes the pressure to equalize between the two pipes. The result is higher performance and less volume. If no alterations have been made to your tailpipes, this step will not be appropriate.

Temporary Fix

4

Drill two very small holes in your tailpipe, about 10 inches from the end.

5

Shove a wad of steel wool into the tailpipe. The wad of steel wool should go in as far as the holes that were drilled. The steel wool will work as a damper to absorb some of the sound without a dramatic effect on the vehicles performance.

6

Thread the wire into one hole, through the steel wool and out the other hole. Twist it around the tail pipe to secure it.
