The Coil Spring Insulator (Rear) is a basic but critical component of the suspension system in your INFINITI. This part is made with rubber and can be found at the top and bottom of your coil springs. These springs help support the weight of your vehicle, keep it at a level height, and absorb road shock. Consequently, the Coil Spring Insulator (Rear) helps guard and support the coil spring. The insulator also helps dull the movement of your coil spring contracting and expanding, which can create a more comfortable ride.
The Coil Spring Insulator (Rear) is designed to withstand the stress of its job. Yet, the rubber can break down and deteriorate over time. This is especially true in areas with extreme temperature fluctuation. After a certain amount of wear, your Coil Spring Insulator (Rear) may stop working well or break altogether. Signs you need to replace your INFINITI Coil Spring Insulator (Rear) include loud road noise, your vehicle bottoming out, and grinding sounds when you turn.
A worn Coil Spring Insulator (Rear) might not pose an immediate threat to your INFINITI, but you still want to replace it in a timely manner. If you don’t, you risk harming other parts of the vehicle, such as your struts, brakes, tires, tie rods, and coil springs. Unless your coil spring is also worn, you can probably get by with only replacing the insulator. Same as the springs, you want to replace your Coil Spring Insulator (Rear) in pairs to help keep your vehicle balanced. If you don't have automotive experience, you should consider bringing your INFINITI into an authorized service center to have the replacement done by professionals.
Your INFINITI Coil Spring Insulator (Rear) is crucial to your suspension system, and you want to make sure you get a replacement made for your vehicle. Shopping OEM parts is a great way to find the right fit.
