How to Replace a Worn-Out Rear Shock Absorber

If you notice a rattling noise when you drive over bumps, you might have a worn-out shock absorber or strut. Often, the noise is not immediately obvious, but can indicate that your vehicle's suspension is not functioning properly. To diagnose the problem, your mechanic should use a diagnostic tool called the Chassis Ear. The Chassis Ear is a portable instrument that can help diagnose a number of car problems, including shocks and struts.

A rear shock absorber is a component in your car that is responsible for absorbing the bumps and turns that your wheels experience while going around a corner. A piston attached to a rod compresses the liquid or gas inside the cylinder, absorbing the shock. The rod then returns to its original position, and the pressure from the piston pushes it back to its resting place, preparing the car for the next shock.

Rear shock absorbers are an essential part of your vehicle's suspension system. They shield passengers from road discomfort and ensure the car's handling is safe. They are round containers filled with gas or oil and contain a metal rod that manages the suspension travel. It also controls the weight of the car. A quality rear shock absorber should last at least five years. However, the life of a shock absorber depends on a variety of factors, including driving style and frequency. If you often carry a heavy load or multiple passengers, it will wear out sooner. Road conditions also influence the wear rate of the rear shock. During rough weather conditions, the shock may not perform at its maximum potential and you will need to replace it sooner.

When replacing the rear shock absorber, it is important to remember that the new one should be compatible with your car's model and brand. If it does not fit, you can get a compatible replacement from an online parts catalog. The new shock should be installed at least one month after your old shock has worn out. You can replace the rear shock with a new one to increase your bike's performance and reduce your weight. If you want to increase the adjustability of the rear shock, consider upgrading it as well.

Replacing the rear shock absorber is relatively simple and straightforward. You will need to remove the wheels and rear shock absorber before you begin. The new shock absorber is then installed and you need to test your tire pressure and spring rate before you drive. Depending on your car, this repair may cost anywhere from $375 to $1200.

While you're replacing the rear shock absorber, you need to check the mounting hardware. Usually, the shock mounts are on studs. You may find it difficult to thread these nuts, but you can use penetrating oil or a thread-locking compound to help you make the process easier. If you find that the mounting hardware has failed to properly secure the shock, you need to replace it. If you have to replace more than one shock, make sure you purchase a new shock box.
