Suspension of a modern crossover Nissan Qashqai is a complex assembly where each element plays a critical role in comfort and controllability. A special place in this system is occupied by silent blocks — rubber-metal joints that dampen vibrations and ensure smooth running. Without their work, the suspension turns into a source of constant noise and shock transmitted to the car body.
Owners Nissan Qashqai often faced with the need to replace these elements, especially with mileage exceeding 60,000 km. Ignoring signs of wear can lead to damage to the suspension arms and even loss of control at high speeds. Critical wear of the silent blocks of the front levers in the first generation Nissan Qashqai often leads to the steering wheel wobbling at speeds above 80 km/h.
In this article, we will analyze in detail how to correctly diagnose a malfunction, which manufacturers offer the most reliable parts, and how to replace it yourself without resorting to expensive services. We will pay attention to technical nuances specific to different generations of the model.
Design and purpose of rubber-metal hinges
The silent block, or rubber-metal hinge, consists of two metal bushings, between which a rubber damper is pressed. In suspension Nissan Qashqai these elements are used in the front and rear control arms, as well as in the anti-roll bars. Their main task is to ensure the mobility of the levers relative to the body, while simultaneously absorbing vibrations from the road.
Without quality work silent blocks the suspension becomes stiff and transfers all the irregularities to the body. This not only reduces comfort, but also increases the load on other components such as wheel bearings and shock absorbers. In design Nissan Qashqai Both regular rubber inserts and polyurethane analogues for sports versions are used.
It is important to understand that the damper material must have a certain elasticity to compensate for the deformation of the lever when turning and braking. If the rubber hardens or cracks, the hinge ceases to perform its functions, which leads to the appearance of backlash.
Signs of wear and diagnostic methods
Determine the fault silent blocks This can be done both visually and by changing the behavior of the car on the road. The most obvious sign is the appearance of dull knocks and squeaks when driving over uneven surfaces. If you hear characteristic sounds even in small holes, this is a reason to immediately check the suspension.
In addition to sound signals, problems are indicated by deterioration in controllability. The car may begin to “scour” along the road, the steering wheel becomes less informative, and when braking, the car may pull to the side. For Nissan Qashqai Characteristic wear of the rear silent blocks, which often manifests itself in a “floating” trajectory on the highway.
A visual inspection of a lifted car allows you to see delamination of rubber or the presence of deep cracks. Dirt and moisture often accumulate inside the bushings, which accelerates the destruction process. Pay attention to whether the metal bushing is offset from the rubber base.

Selection of manufacturers and spare parts analogues
Spare parts market for Nissan Qashqai offers a wide range of options: from original parts to high-quality analogues. Original silent blocks from Nissan are distinguished by high quality rubber compounds and precision manufacturing, but their cost is often inflated. In addition, the original lever assemblies are very expensive, and it is often more profitable to buy separate hinges.
Among the best alternative manufacturers, it is worth highlighting German brands such as Lemförder and Sidem. These companies supply components to the assembly lines of many automakers, so their products are highly reliable. Also popular are products from the brands Febi Bilstein and TRW, which offer the best value for money.
Polyurethane silent blocks, for example, from the SuperPro brand, are an excellent choice for those who love an active driving style. They are more durable and tougher than rubber ones, but require careful installation and proper lubrication. For standard city use, it is better to stay on high-quality tires.
| Manufacturer | Material type | Service life (km) | Price (guideline) |
|---|---|---|---|
| Nissan (Original) | Rubber | 80 000 - 100 000 | High |
| Lemförder | Rubber | 70 000 - 90 000 | Average |
| SuperPro | Polyurethane | 100 000+ | High |
| Febi Bilstein | Rubber | 60 000 - 80 000 | Average |
Before purchasing, be sure to check the part number, since for different generations of Qashqai (J10, J11) silent blocks may differ in size and rubber hardness.
Preparation for replacement and necessary tools
The process of replacing silent blocks requires special equipment and tools. You will need a jack, stands for the car, a set of sockets and keys, and a puller for squeezing out silent blocks. Without a specialized press or puller, removing old bushings and pressing in new ones will be extremely difficult, and sometimes impossible.
Be sure to prepare cleaning supplies to remove dirt and old grease from the levers. You will also need high-quality lubricant to install new hinges so as not to damage the rubber during installation. For Nissan Qashqai Often the arm needs to be removed from the vehicle, which makes working with the puller easier.
It is important to ensure safe work: the car must be securely supported on stands, and not just on a jack. Before starting work, make sure you know the location of all bolted connections and their tightening torques. Incorrect tightening can lead to rapid failure of new parts.
☑️ Preparation for replacement
Step-by-step replacement instructions
Start by lifting the car and removing the wheel to access the suspension. Loosen the lever mounting bolts, but do not completely unscrew them until the lever is raised on the stand. This will avoid deformation of the rubber in the new silent blocks when installing them.
Use a puller to push out the old silent block. Make sure you use the correct adapters to avoid damaging the threads or the lever body. Clean the seat from rust and dirt, treat it with a protective compound. Pressing in of the new hinge should occur smoothly, without distortion.
After installing all silent blocks, tighten the lever mounting bolts. This will ensure the tires work properly and prevent premature wear.
What to do if the silent block cannot be squeezed out?
If the old joint is stuck, use a penetrating lubricant and give it time to work. In extreme cases, you can gently heat the metal sleeve with a blowtorch, but be careful not to melt the rubber in the lever.
The final tightening of the lever bolts must be done under the load of the vehicle on wheels, otherwise the silent blocks will quickly collapse from distortion.
Features of replacement on different generations
First generation Nissan Qashqai (J10) has its own characteristics in the design of the rear suspension, where a multi-link design is used. Here, the silent blocks of the rear levers are subject to high loads and often require replacement. The design of the front arms is also different from newer models, which is important to consider when selecting a tool.
The second generation (J11) received a more advanced suspension, but the operating principle of the silent blocks remained the same. However, the size and hardness of the rubber inserts may vary. J11 owners should pay attention to the rear wishbones, where wear occurs faster due to the design features.
Do not forget that after replacing silent blocks on any generation Nissan Qashqai wheel alignment needs to be done. Any intervention in the suspension geometry requires adjustment of the wheel alignment angles to ensure stable movement and uniform tire wear.
- 🛠️ J10: Special attention to the rear arms and their mounting
- 🛠️ J11: Checking the front wishbones and stabilizer
- 🛠️ General: Mandatory wheel alignment adjustment after work
⚠️ Attention: Do not try to install polyurethane silent blocks on the rear multi-link suspension without consulting a specialist, as this may change the kinematics and worsen comfort.
Frequent maintenance errors
One of the most common mistakes is tightening the suspension bolts while the car is raised. This creates pre-stress in the silent blocks, which leads to their rapid destruction. Always lower the machine to the ground before final tightening of the control arms.
Another mistake is using the wrong lubricant. Some drivers use solid oil or graphite lubricant, which are aggressive to rubber. This may cause the rubber part of the hinge to swell or crack. Use only special silicone lubricants or those recommended by the manufacturer.
Ignoring the condition of other suspension elements also leads to problems. If you replaced the silent blocks, but left worn shock absorbers or levers, the new parts will not last long. An integrated approach to suspension repair is the key to long vehicle service.
Is it possible to replace only the silent block rubber?
Technically possible, but highly not recommended. The metal sleeve often becomes deformed when the old rubber is removed, and the new sleeve may not fit tightly, which will lead to play.
FAQ: Frequently asked questions
How long do silent blocks last on a Nissan Qashqai?
On average, the service life ranges from 60,000 to 100,000 km, depending on operating conditions, road quality and spare parts manufacturer.
Is it necessary to do a wheel alignment after replacing the silent blocks?
Yes, definitely. Replacing silent blocks changes the geometry of the suspension, so for the correct position of the wheels, adjustment of the installation angles is necessary.
Is it possible to drive with a cracked silent block?
It is possible for a short time, but not recommended. The crack will quickly spread, which will lead to complete destruction of the hinge and loss of controllability.
Which silent blocks are better: rubber or polyurethane?
Rubber tires are better suited for urban use, as they provide better comfort. Polyurethane is stiffer and more durable, but transmits more vibrations to the body.
How often should the condition of the suspension be checked?
It is recommended to carry out a visual inspection of the suspension every 15,000 km or when unusual sounds appear while driving.
