Compare coil spring replacement quotes from specialist garages in Cardiff

Car suspension features four coil springs, one for each wheel. They are designed to absorb shocks from the road, such as driving over a pothole or speed bump, and they work in conjunction with shock absorbers.

Eventually, coil springs become fatigued with age, which means they have endured many compression-extension cycles, causing the metal to become brittle. When this happens, it's time for a coil spring replacement. This job typically takes one to three hours for front springs and one to one and a half for rear springs.

A coil spring usually lasts between 60,000 and 90,000 miles. Signs you may need new springs include: excessive tyre wear, visible rust or corrosion on the springs, excessive leaning or swaying, compromised handling and worn or missing jounce bumpers. A rear or front coil spring repair is always done by replacing the springs; once the metal becomes brittle, it can't be repaired.
