Suspension problems with the Dacia Logan are quite common and often show up as knocking noises, especially on rough roads. Worn bushes and shock absorbers are the main causes of these annoying symptoms. With the right knowledge and timely repairs you can resolve these issues effectively. This restores the ride comfort of your car.
What causes the knocking in the suspension
You hear knocking noises. These usually come from the front or rear axle. Suspension components lose their damping effect. That is the cause. Worn rubber bushes no longer prevent metal-to-metal contact, which means every bump becomes directly audible. The shock absorbers are past their best. They no longer absorb the vertical movements of the wheel suspension properly.
Ball joints in the control arm form another very common cause. These joints connect the wheel suspension to the chassis. They ensure smooth movement while steering. The joints wear out. This creates play that manifests itself as a knocking sound. The Dacia Logan is sensitive to this, especially when the vehicle is regularly used on poor roads.
Many Dacia Logan models do not have an anti-roll bar at the front. This design feature makes the car more sensitive to sideways movements. It contributes to increased wear on other suspension components. The extra load on bushes and control arm components accelerates the point at which wear becomes noticeable.

Recognisable symptoms of suspension problems
The knocking is rarely the only sign. You will often first notice that ride comfort is deteriorating. The car feels less stable and shocks are transmitted more harshly to the bodywork. You take a corner. The car then leans more than usual. This is a sign that the damping is no longer working optimally.
Steering wheel vibrations point to worn components in the front axle. This is linked to worn ball joints or control arm bushes. These have developed play. The steering behaviour also changes: the car responds less directly to steering inputs or feels vague while driving.
Uneven tyre wear is another warning sign. Suspension components are worn. The wheel suspension is then no longer in the correct position. This leads to irregular wear on the tyres. Pay particular attention to wear on the inner or outer edge of the tread.
Which parts wear out first
On the front axle, the pins of the control arm bushes (small metal pins that connect the control arm to other components) are the most prone to wear. These relatively small parts carry a large load. They are in direct contact with the moving parts of the suspension. Fortunately, replacement does not have to be expensive. Complete control arm units for the Logan are affordable.
The rubber bushes connect the control arm to the chassis. They wear particularly quickly with intensive use on poor road surfaces. The rubber loses its elasticity and eventually tears. This causes noise. It also affects wheel alignment. Shock absorbers have a finite service life. They gradually lose their damping capacity.
At the rear similar problems can be expected. Here too bushes and shock absorbers wear out. The symptoms are less directly noticeable in the steering behaviour. They can, however, be heard as knocking noises from the rear of the car.
How do you fix worn suspension bushes
Replacing suspension bushes requires some technical knowledge and the right tools. You must put the car on a lift or safely raise it with axle stands. You then need to remove the wheel suspension components. This gives you access to the bushes. Old bushes are driven out with a special tool and new bushes are pressed in.
For many owners, professional help is recommended. A workshop has the right tools. This allows them to replace bushes efficiently without damaging surrounding components. A mechanic will immediately check whether other suspension components also need attention. This prevents you from facing new problems shortly after the repair.
You have replaced bushes or other suspension components. A wheel alignment is then necessary. The mechanic must reset the geometry of the wheel suspension according to the manufacturer’s specifications. Without this adjustment the steering behaviour will remain abnormal. Tyres will then wear unevenly.
‘ Suspension problems are not a Logan-only phenomenon. ’
Are these problems typical of poor roads
The Dacia Logan has been designed as an affordable and robust car. Intensive use on poor road surfaces does, however, accelerate wear of suspension components. Bumps, potholes and uneven tarmac put more stress on the suspension. Smooth road surfaces put less stress on it. Every shock has to be absorbed by bushes and shock absorbers, which makes them age faster.
The Logan is not unsuitable for use on poorer roads. The car performs well there. Many owners drive for years without major problems. Even under tough conditions they drive without issues. The difference lies in the maintenance schedule (how often you have your car serviced and parts replaced). More frequent inspections keep the suspension in good condition. Timely replacement of worn parts ensures optimal suspension performance.
Comparison with other models in this segment shows something. Suspension problems are not a Logan-only phenomenon. Compact saloons in this price range show similar sensitivity to wear. The advantage of the Logan lies in the low cost of replacement parts. Its relatively simple construction is also an advantage.
How much does it cost to repair the suspension
One major plus point of the Dacia Logan is the affordability of maintenance. Replacement control arm units (complete assembled components for the wheel suspension) cost significantly less than for many other brands. Rubber bushes and ball joints are also widely available at reasonable prices. This makes the car attractive for budget-conscious owners.
Labour costs vary by workshop and region. An independent garage usually charges lower hourly rates than a main dealer. For standard suspension repairs such as replacing bushes or control arm components, several hours of labour are needed. Expect a few hours of work. Replacing shock absorbers is usually quicker.
Preventive maintenance (regular inspection and replacement before serious problems occur) prevents higher costs later on. Regular checks of suspension components detect early signs of wear at an early stage. This gives you the opportunity to plan repairs. This way no secondary damage occurs. A worn bush, for example, can damage the control arm itself. That means a more expensive repair.
Tips for long-term reliability
Schedule annual inspections. A mechanic will then inspect the complete suspension. The check includes a visual inspection for cracks in rubber components, play in ball joints and the condition of the shock absorbers. This way you detect problems early. Early detection of problems gives you time to prepare for repairs.
Also pay attention yourself to any changes in how your car behaves on the road. New noises, abnormal steering behaviour or reduced comfort are signals. Do not ignore them. You will react sooner. The damage will then remain more limited. Do not keep driving with obvious knocking noises, as this leads to unsafe situations.
Use quality parts (components that meet reliable standards and fit properly) when replacing items. Extremely cheap alternatives do not last as long. They will require new repairs sooner. Brand dealers and reputable aftermarket suppliers (suppliers who offer parts that do not come from the original car manufacturer but do meet the specifications) offer parts that match the Logan’s specifications well. The choice of workshop also makes a difference. An experienced mechanic knows the typical weak points. He will therefore carry out a targeted inspection.

Frequently asked questions
You often recognise wear on the suspension of your Dacia Logan by abnormal knocking or tapping noises at speed bumps and on poor roads. Reduced ride comfort, more vibrations in the steering wheel and unsettled behaviour in bends are also clear signals. Also watch out for poorer or less direct steering response and any uneven or irregular tyre wear. If you notice one or more of these symptoms, have the suspension checked in a workshop as soon as possible.
The most common suspension problems with a Dacia Logan are wear of the ball joints in the control arms and worn suspension rubbers. Drivers often notice this through knocking noises and vibrations, especially when driving over uneven road surfaces. Reduced effectiveness of the shock absorbers and unsettled cornering behaviour also occur regularly. Fortunately, the parts and repairs for the Logan’s suspension are generally relatively inexpensive.
On the Dacia Logan, it is mainly the ball bearings/ball joints in the control arms (wishbones) that are most prone to wear. In addition, rubber bushes and rubber mountings in the suspension wear relatively quickly, which can lead to knocking noises and play. Shock absorbers can also lose their effectiveness over time, causing vibrations and reduced ride comfort. Regular inspection of these components is therefore important.
The average costs of repairing suspension problems on a Dacia Logan are generally relatively low, because the parts are inexpensive and the labour time is limited. Many common components, such as complete control arms (wishbones), cost according to the source less than about 25 US dollars each, excluding labour. In total, repair costs for standard suspension work therefore usually end up in the low to mid hundreds of euros, depending on the number of parts to be replaced and the garage’s hourly rate.
Have the suspension checked annually, including rubbers, ball joints, control arms and shock absorbers, so that wear is detected early. Respond immediately to knocking noises, vibrations or uneven tyre wear and have worn components replaced straight away. Avoid driving on poor road surfaces and over high speed bumps at high speed as much as possible to limit extra stress. Use quality components instead of the very cheapest alternatives, as those often wear out more quickly.
