The Coil Spring Insulator (Rear) is a small but critical component of the suspension system in your INFINITI. This part is composed of rubber and is located 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 support and protect the coil spring. The insulator also helps suppress the motion of your coil spring contracting and expanding, which can create a steadier ride.
The Coil Spring Insulator (Rear) is designed to withstand the strain of its job. Yet, the rubber can break down and deteriorate over time. This is especially true in areas with extreme temperature fluctuation. Your Coil Spring Insulator (Rear) might break or stop working well after a certain amount of wear and tear. Signs you need to replace your INFINITI Coil Spring Insulator (Rear) include your vehicle bottoming out, grinding sounds when you turn, and loud road noise.
A worn Coil Spring Insulator (Rear) might not pose an immediate threat to your INFINITI, but you still want to replace it quickly. When you wait to replace it, you risk damaging other parts of your vehicle, such as your struts, brakes, tires, tie rods, and coil springs. Unless your coil spring also appears worn or damaged, you can usually get by with only replacing the insulator. Same as the springs, it’s recommended that you 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 vital to your suspension system, and you want to make sure you get a replacement made for your vehicle. Shopping OEM-made parts is an easy way to find the right fit.
