BMW X3 Coil Springs

The height of your BMW changes slightly to absorb the shock when driving over bumps or rolling over rocks. The wheels lift up to navigate the bumps, and then the rear coil springs push the car back down so that you can maintain proper control and efficient handling. Because suspension parts help the automobile handle better, its important to replace them as soon as you are aware that they have been damaged.

When do coil springs need to be replaced?

Coil springs have no specific useful life. Over time, they gradually lose their flexibility and become less effective. If your springs are failing, you will notice that your BMW X3 doesnt ride as smoothly as it once did. It will also sit lower to the ground. You may also notice odd cracking and creaking noises coming out from under the car as you drive. These noises are likely to get louder when you drive over bumps and holes in the road. If a coil suddenly breaks, you will notice an immediate change in handling and may lose a tire if the rough edge of the broken part slices into the side wall.

Do coil springs need to be replaced in pairs?

In order to keep your X3 sitting straight, always replace suspension parts in pairs rather than doing so one at a time. Replacing the piece on one side of the X3 but not the other will leave the vehicle sitting lopsided and can put undue pressure on the old part, increasing the odds that it will break too.

How are tapered springs different?

Some coil spring manufacturers produce tapered coil springs. As the name suggests, these pieces are tapered, or narrower, on the ends. This type of design reduces the weight of the vehicle, making it a frequent choice among racers. Unfortunately, tapered ends mean less metal in the unit overall, potentially making the spring a bit weaker and more likely to break. While workable on the track, tapered springs are generally not the optimal choice for a vehicle that gets used daily.

How do you protect BMW X3 coil springs?

If you live in an area where vehicle rust problems are common, consider having your new rear coil springs powder coated. The powder coat process encases the pieces in an exterior coating that will help protect them from rust to last longer. Unlike traditional paint, powder coating moves and flexes as needed to minimize the chance of cracked paint that allows water to reach the spring. Preventing rust in this way can greatly prolong the life of your coil springs.
