The spacious Toledo invites heavy loading. However, that loading speeds up wear on the rear suspension. Broken rear springs are a common problem with this model, especially when owners regularly push the car’s load capacity. At the MOT, a broken rear spring leads to immediate failure. Careful loading practices prevent unnecessary damage and keep you within the safe limits of your car.
Why rear springs break faster with heavy loading
The rear suspension of your Toledo consists of coil springs that carry the weight of the car and absorb impacts. With every bump these springs are compressed and released again. That constant cycle of compression causes metal fatigue over time, especially when the springs are regularly heavily loaded.
Heavy load in the boot significantly increases the pressure on the rear springs. The rear springs are the coil springs at the back of your car. They carry the weight of the load in the boot. Think of a fully loaded boot with holiday luggage, building tools or heavy groceries. You drive over kerbs with that weight. You brake hard. The springs then have to work harder. That speeds up wear.
In addition, the combination of moisture, road salt and dirt causes corrosion on the outside of the springs. The rear springs sit low to the ground. They are more exposed to the road surface and spray. Rust weakens the metal and makes the spring more prone to breaking.
Factors that accelerate spring failure
- Regular overloading of the boot above the permitted payload
- Driving over sharp kerbs or potholes with a loaded rear end
- Age of the springs: after around 10 years the spring rate decreases
- Age of the springs: at high mileages the spring rate decreases
- Exposure to road salt and moisture that cause corrosion
‘ That significantly increases the risk of spring failure. ’
What is the maximum payload of your Toledo
The payload of your Toledo is listed on the registration certificate and in the owner’s manual. This figure indicates how much weight you are allowed to load on top of the car’s kerb weight. The payload includes the load in the boot. It also includes the weight of all occupants and any roof racks or bike carriers.
For most Toledo models, the payload is between 400 and 500 kilograms. If you exceed this weight, you put extreme pressure on the rear suspension. That significantly increases the risk of spring failure. Regularly check how much weight you are carrying, especially on longer journeys or when you are transporting heavy items.
Also pay attention to how the weight is distributed. The rear springs become unevenly loaded when the boot is heavily loaded on one side. This can lead to faster wear on that side and increases the chance that one spring will break before the other.
How to recognise a broken rear spring
A broken rear spring often gives clear signals. The most noticeable is that the rear of your car sags or leans to one side. This is especially obvious when you load the boot with weight. Even without any load, the car can sit lower on one side than on the other.
While driving you hear knocking or bouncing noises, especially in tight corners. The broken end of the spring moves against other components, causing these sounds. The spring can also be loose in the spring seat. On uneven roads the car feels unstable and the steering wheel vibrates more than normal.
During a visual inspection underneath the car, you can sometimes see the broken end of the spring. In some cases, a loose piece of the spring can even drop down. During the MOT, the springs are routinely checked for breaks. This is regarded as a direct safety risk.
Symptoms of a broken rear spring
- Car leans to one side or sags on one side
- Knocking noises when cornering, steering or driving over bumps
- Unstable handling and harsh jolts over small potholes
- Visible break or broken ends underneath the car
How much does it cost to replace the rear suspension
The cost of replacing rear springs varies. The model and the garage determine the amount. For the Toledo, the cost of new rear springs is usually between 100 and 200 euros per spring. It is also advisable to have both springs replaced at the same time. On top of that come the labour costs at the garage, which are often between 150 and 300 euros for replacing both rear springs.
It is sensible to replace both rear springs at the same time, even if only one is broken. Springs on the same axle wear at roughly the same rate. If you replace only the broken spring, a height difference will arise between left and right. This leads to uneven handling and speeds up wear on the other spring.
Some Toledos are older and have covered high mileages. For these cars, it is often worthwhile to replace the shock absorbers at the same time. Shock absorbers wear together with the springs. You replace them in one go. That saves labour costs, although it does bring the total cost to around 400 to 600 euros. However, it prevents you from having to go back to the garage again shortly afterwards.

Prevent spring failure with these practical tips
Prevention is better than cure. Be mindful of how you load your Toledo. This significantly extends the lifespan of the rear springs. Regularly check the weight of your load and stay well below the maximum payload. Also avoid sudden loading. You drive fast over a kerb. You take a speed bump at full speed.
Clean the underside of your car regularly, especially in winter when there is road salt on the roads. This slows down corrosion on the springs. Also check how the springs are seated in the spring cups. With some aftermarket sets, springs can sit crooked in the recesses. That creates extra stress and increases the risk of breakage.
Have the rear suspension checked every year during the MOT. Also have the rear suspension checked annually during routine servicing. A mechanic can detect early wear or initial corrosion before the spring actually breaks. Early detection saves you the cost of failing the MOT and prevents unsafe situations on the road.
Maintenance tips for a longer lifespan
- Stay well below the maximum payload
- Avoid heavy impacts by driving carefully over speed bumps and kerbs
- Clean the underside of the car to prevent corrosion
- Replace both rear springs at the same time
- Have the condition of the rear suspension checked annually during servicing
Regularly check the weight of your load and listen out for noises from the rear. If in doubt, have a mechanic inspect the rear suspension before you go on a trip with a loaded car. This way you avoid failing the MOT and keep your Toledo safe on the road.
Frequently asked questions
You often recognise a broken rear spring by a rear end that leans or sags, sometimes with visibly broken spring ends. Symptoms of problems with the rear suspension include knocking or bouncing noises over speed bumps and in corners, unstable handling and vibrations on uneven roads. The car can also feel harsh and jarring over small potholes or bumps. When loaded, the rear sags down much further, which indicates reduced spring strength or breakage.
The main causes of spring failure are metal fatigue due to wear, overloading (a lot of weight or heavy impacts), corrosion from moisture and road salt, and ageing with high mileage. You can prevent problems by avoiding overloading and heavy impacts (such as kerbs), regularly cleaning (or having cleaned) the underside to prevent rust, and having the rear springs visually inspected, for example at the MOT. Always replace both springs on one axle at the same time and ideally combine this with new shock absorbers every 80,000–100,000 km. Watch out for symptoms such as a leaning car, knocking noises and unstable handling, and have these checked immediately.
Continuing to drive with a broken rear spring is dangerous because the car becomes unstable, especially in corners, over bumps and when loaded, which increases the risk of skidding or losing control. The rear can sag or lean, making the handling unpredictable and adversely affecting braking and steering response. Knocking and bouncing movements also increase, meaning the car maintains less consistent contact with the road. As a result, both comfort and safety are seriously reduced.
In case of spring failure or clear wear, the standard option is to replace the rear springs, ideally left and right at the same time, often combined with new shock absorbers and bearings. You can then choose original springs, reinforced springs (for frequent heavy loading) or a lowering kit for sportier handling. Handy DIYers can do this at home with the right tools (such as a spring compressor) and a simple rear axle design. With a complex suspension setup, rust, or lack of experience, it is safer and more sensible to have the work carried out in a garage.
