- Rubber part at top and bottom of coil spring
- Helps support and protect coil spring
- Replace when worn or not working correctly
The Coil Spring Insulator (Rear) is a small but important component of your vehicle's suspension system. This part is made with rubber and is located at the top and bottom of your coil springs. The springs help absorb road shock, support the weight of your vehicle, and keep it at a level height. Consequently, the Coil Spring Insulator (Rear) helps support and protect the coil spring. The insulator also helps dull the movement of your coil spring contracting and expanding, which can create a steadier ride.
The Coil Spring Insulator (Rear) is designed to sustain the stress of its job. Yet, the rubber may break down and deteriorate over time. This is particularly true in climates where temperature fluctuation is common. 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 should still replace it in a timely manner. If you wait too long, you might damage other parts of your vehicle, such as your struts, brakes, tires, tie rods, and coil springs. Unless your coil spring is also showing signs of wear, you can usually make out with only replacing the insulator. Like the springs, you want to replace your Coil Spring Insulator (Rear) in pairs to help keep your vehicle balanced. If you aren’t experienced working with cars, 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 a great way to find the right fit.
