Why do my car springs keep breaking?
Why do my car springs keep breaking?
Most springs fail due to fatigue, meaning they have sustained many compression-extension cycles, and the metal becomes brittle and breaks. If the amplitude of these cycles is large, the fatiguing process is accelerated. Cars with continually overloaded trunks are candidates for early spring failure.
Can you drive a car with a broken front spring?
No. It is not recommended. A damaged or collapsed spring can cause sagging and noise and affect alignment angles. While you can still drive, the ride will be rough and the car will be difficult to control in an emergency.
Is it common for car springs to break?
Coil springs are covered in a flexible plastic coating to help protect the metal from corrosion. However, over time, with constant compression and being hit by stones from the road, this coating can get damaged, allowing rust to form on the coil. Once this happens, the coil can weaken and potentially break.
Why do front coil springs break?
During the winter months, ice, snow, cold temperatures and salt to the roads can cause accelerated corrosion of a coil spring. Wheel imbalances due to misalignment or damaged tyres can cause uneven wear to your car’s suspension, which can lead to the damage and breakage of coil springs.
How to calculate the spring rate for a car?
If you’re guessing blindly, use a 55%/45% weight balance; however, it is much more appropriate to measure your car. Example corner weight using weight balance: To get the corner weight of your car, take an example total weight of 3800 lbs and multiply it by the front end weight bias. ex: 3,800 x 55% (front end weight balance) = 2,090.
What causes a spring in a car to break?
Overloading: A spring that is greatly overloaded can break, but as with bumps, it takes greatly excessive load, usually far in excess of the vehicle’s load rating, to break a typical automotive spring that’s in good condition. Rust: Almost all automotive springs are made of steel, and all steel rusts to some extent.
Why do passenger cars have higher spring rates?
It’s interesting to note that more often than not passenger cars are setup with higher rear suspension frequency, since this helps bumps in the road to be absorbed “in synch” by the front and rear suspension and has the effect of smoothing out the ride quality.
What kind of car has broken front springs?
Both springs are fully supported – it’s just the last bit on both sides which is broken off. Also, anyone have any suggestions how it could have happened? Both sides are equally rusty, so I’m guessing some kind of knock which caused them both to break. Car is a TD5 Landrover Disco II.

Why are the springs on my car breaking?
While many people do cut their springs, it is a calculated cut hopefully balancing ride height and spring rate. In my experience the most common cause of broken springs is worn struts. Worn struts lack the rebound and dampening controls which allows the spring to overcompress and overextend weakening it.
How to calculate spring rate for Qa1 coil over?
Once your front end weight has been calculated, simply choose the suggested spring rate. For a larger version, see our Spring Rate Chart & Vehicle Weight Sheet. QA1 also offers cataloged bolt-in rear coil-over kits for popular applications.
