Dos and Don'ts When Buying a Coil Spring Insulator
The coil springs in your vehicle are protected by coil spring insulators. Aside from being integral components of your car's suspension system, they also perform a dampening function on the coil springs' up and down movement. Since coil spring insulators are usually made of rubber, they wear fast and require regular replacement. When you're looking for replacement insulators, it's important to consider these do's and don'ts.
- Inspect both your coil springs and coil spring insulators. Check if the worn insulators damaged or affected the coil springs' top and bottom sides. This is to determine if you need to replace the coil springs together with the insulators.
- Always prefer direct fit to universal coil spring insulators. It gives you ease in choosing whether an insulator would be compatible with your coil springs or not.
- Search for a coil spring insulator made of polyurethane. Rubber insulators wear easier and quicker compared to polyurethane ones. Insulators made of polyurethane are soft enough to dampen the force from the springs while being sturdy enough to last longer than rubber ones.
- Buy coil spring insulators that are packed with additional features aside from durability. Some of these added features are the capacity to increase ride height and the ability to prevent grinding noise caused by metal-to-metal contact.
- Don't buy coil spring insulators sold at suspiciously lower prices. The prices of coil spring insulators range from $4 up to $70. If you're offered a coil spring insulator for only $2, get your guard up. Check your supplier and the insulator itself.
- Don't force an incompatible insulator into your coil springs. This may damage your coil springs and can lead to suspension system failure. If you've bought an incompatible coil spring insulator, you may return it to the store and ask for a replacement, so long as you haven't damaged it.
- Don't purchase a warranty-less coil spring insulator. Being covered with a warranty gives you peace of mind and assurance that your insulators are backed up by your manufacturer in cases of factory defects.
- Don't consider coil spring insulators made of substandard material. Accept only polyurethane coil spring insulators and disregard the old rubber-made ones. Installing rubber insulators will just force you to change your coil spring insulators frequently.
How to Replace Your Car's Coil Spring Insulator
The weight of your Chevrolet truck is supported by coil springs. These integral components of the suspension system are covered with coil spring insulators, which dampen the force exerted on the metal springs. Since the insulators are made of rubber, replacing them immediately when they get worn is recommended.
Difficulty level: Moderate
Tools to be used:
- Jack and jack stands
- Tire iron
- Pry bar
- 3/8-inch ratchet and socket set
- Open-end wrench set
- Locking pliers
- New coil spring insulator
Step 1: Find a level surface to park your car. Engage the parking brake and grab your jack and jack stands.
Step 2: Raise your vehicle with a jack. Support it with jack stands by placing the stands directly under the frame. Remove your car's front tires and set them aside.
Step 3: Get your 3/8-inch ratchet and socket, open-end wrench set, and locking pliers. Using these, detach the shock absorber from the front suspension. Take the shock out from the bottom of the lower control arm and put it aside.
Step 4: Raise the jack so that it gets on the bottom of the lower control arm. Use the 3/8-inch ratchet and socket to detach the tie rod end and the upper control arm from the steering knuckle. Hit the knuckle's side with a sledgehammer to separate the knuckle from the upper control arm.
Step 5: Lower the jack and get a pry bar. Detach the coil spring from the front suspension by pulling the spring cautiously. Then, pull the old insulator from the coil spring's top.
Step 6: Wrap the new insulator around the top of the coil spring and use the pry bar to reinstall the coil spring into the suspension. Lift the jack and use the 3/8-inch ratchet and socket to bolt the tie rod and upper control arm to the steering knuckle.
Step 7: Put the shock back using the locking pliers, open-end wrench, and 3/8-inch ratchet and socket. Replace the front wheels and lower your Chevy from the jack and jack stands.
