Many crossover owners Nissan Qashqai The first generation encounters a characteristic knocking sound in the front suspension after a run of 80–100 thousand kilometers. Most often, the problem lies not in shock absorbers or springs, but in worn rubber-metal joints, which are called silent blocks. It is these elements that ensure a smooth ride and dampen vibrations transmitted from the road to the body.
Ignoring signs of wear leads to accelerated destruction of the levers themselves, disruption of wheel alignment and, in the worst case, loss of controllability at high speed. Owners often wonder whether it is worth replacing the lever assembly or whether only the rubber bushings can be replaced. For model Nissan Qashqai J10 A rational solution is to replace the silent blocks, since this is cost-effective and allows you to preserve the original suspension geometry.
Symptoms of wear and diagnostics of suspension
The first signal about the need for diagnostics is the appearance of a dull knock when driving over bumps, especially at low speeds. This sound is often confused with a malfunction of the shock absorbers, however, when you press the lever with your hand at the junction with the silent block, you may feel play or hear a characteristic creak.
The second important sign is uneven tire wear. If you notice that the inner or outer edge of the tread is wearing faster than the rest of the tread, this indicates a misalignment in the suspension geometry. On Nissan Qashqai this often happens because the rubber element in the silent block has dried out or torn, and the lever begins to “walk” in the seat.
The third symptom is deterioration in directional stability. The car can move to the side on its own when driving in a straight line, which forces the driver to constantly steer. In this case, it is necessary to check not only the silent blocks, but also the condition of the steering tips, and also perform a wheel alignment.
- 🔊 Extraneous sounds: knocking, creaking or hum when passing speed bumps.
- 🛞 Tire wear: uneven wear on the front tire tread.
- 🎮 Controllability: car yaws along the road and “wobbly” steering wheel.
⚠️ Attention: If you notice that the rubber part of the silent block has completely peeled off from the metal bushing, operating the vehicle is prohibited. This can lead to the lever coming off and causing an accident.
Selection of spare parts: original or analogue
When choosing new parts for suspension repairs Nissan Qashqai J10 A dilemma arises: buy original Nissan parts or high-quality analogues. The original silent block, as a rule, has a high cost and is supplied either assembled with a lever, or as a separate part with a long waiting period in the warehouse.
There are trusted manufacturers on the market who offer products that are not inferior in quality to the original, but at the same time affordable. Brands like Lemförder, TRW or Febi Bilstein have established themselves as reliable suppliers of rubber-metal products for Japanese cars. Their products are often manufactured in the same factories as the original parts.
There is no point in saving on buying cheap Chinese analogues, since their service life can be only 15–20 thousand kilometers. Cheap rubber quickly hardens in the cold or, conversely, softens in the heat, losing its damping properties. The right choice is the key to safety and comfort for a long time.
- 💎 Original: High price, quality guarantee, but often sold only assembled.
- 🏆 Premium class analogues: Optimal price-quality ratio (Lemförder, Febi).
- ⚠️ Cheap analogues: Risk of rapid failure, poor geometry.

Necessary tools and preparation
To perform the work efficiently, you will need not only a set of keys, but also specialized equipment for pressing out old bushings and pressing in new ones. Without a hydraulic press or special pullers, the process can take days or end in damage to the lever.
A basic set of tools includes a jack, car stands, a set of sockets (usually from 14 to 21 mm), a torque wrench and a pry bar. Also, don't forget to use a penetrating lubricant (WD-40 or equivalent), as the arm bolts often become stuck due to road salt and dirt.
It is most convenient to work on a viewing hole or a lift. If you plan to change the bushings on both front control arms, it is better to prepare a kit for both wheels at once to avoid repeated suspension disassembly in the future. Also inspect the condition of the bolts: if they are damaged or have broken threads, they need to be replaced with new ones.
- 🔧 Tools: Hydraulic press, socket set, torque wrench.
- 🛠 Consumables: Penetrating lubricant, new bushing grease, brake cleaner.
- 🏗 Equipment: Inspection hole or lift, reliable stands for the body.
⚠️ Attention: Never use a gas torch to loosen stuck bolts on the suspension arms. High temperatures can damage the metal structure and weaken the lever.
☑️ Preparation for replacing silent blocks
Step-by-step replacement instructions
Begin the process by removing the wheel and unscrewing the bolts securing the lever to the steering knuckle. Usually a large diameter bolt is used, which requires significant force to unscrew. After this, disconnect the lever from the body by unscrewing the front and rear mounting points.
The removed lever must be clamped in a vice and prepared for pressing out the old silent block. Use a hydraulic press or special puller to press out the old bushing. Do this carefully so as not to damage the seat on the lever itself. If the lever has signs of corrosion or cracks, it is better to replace it entirely.
Before installing a new silent block, clean the seat from dirt and rust. Apply a thin layer of special grease to the outer surface of the new bushing to facilitate pressing. Press the new part strictly in the center, controlling the installation depth.
Install the lever on the car in reverse order. It is important to only tighten the mounting bolts when the vehicle is on its wheels and the suspension is under load. This will ensure the correct position of the rubber-to-metal joints and extend their service life.
- 🚗 Dismantling: Unscrew the bolts securing the body and steering knuckle.
- 🔨 Pressing out: Use a press to remove the old worn element.
- 🛠 Pressing: Install a new silent block using lubricant and a press.
- 🔩 Installation: Assemble the suspension and tighten the bolts under load.
What to do if the silent block does not press out?
If the old silent block is stuck, do not use brute force. Try using chemical rubber solvents or gently heating the outer race (not the lever itself!) to cause the metal to expand. Sometimes a shock attachment helps, but only on the metal part of the bushing, avoiding contact with the rubber and aluminum body of the lever.
Before starting work, be sure to mark with a marker the position of the lever relative to the body in order to maintain the approximate geometry during assembly and perform wheel alignment faster.
Design features of the Nissan Qashqai J10
Model suspension Nissan Qashqai J10 has its own design features that distinguish it from many competitors. The front suspension is made according to the McPherson design, but the arms have a complex shape and are attached to the body through two silent blocks: front and rear. The rear silent block often experiences heavy loads during braking and acceleration.
Particular attention should be paid to the bolt securing the lever to the steering knuckle. On Qashqai This bolt has a conical fit, and when dismantling it, care must be taken so that it does not fall out and damage the threads. It is also important not to overtighten the nuts, as this can lead to rapid destruction of the rubber bushings.
Corrosion is the main enemy of the aluminum control arms on this crossover. An oxide film often forms in the places where the bolts are attached, which interferes with normal tightening. Regular cleaning of the suspension and treatment with anti-corrosion compounds will help keep the levers in good condition.
Check after repair and wheel alignment
After replacing the silent blocks, be sure to perform the wheel alignment procedure. Any intervention in the suspension geometry changes the wheel alignment angles. Without adjusting these parameters, the car will pull to the side, and the tires will wear unevenly after just a couple of thousand kilometers.
Take it for a test drive, paying attention to the car's behavior when braking and cornering. If the knocking noises have disappeared and the steering wheel has become more informative, then the work has been done efficiently. If new sounds appear, immediately return to the station for re-diagnosis.
The rubber in the silent blocks must take its working position, so for the first 500–1000 kilometers, aggressive driving and deep holes should be avoided.
- 📐 Wheel alignment: Mandatory procedure after replacing levers.
- 🛣 Test drive: Check for any knocking or beating of the steering wheel.
- ⏳ Break-in: Avoid extreme loads for the first 1000 km.

Replacing the bushings is a cost-effective alternative to buying new arms, but it requires the use of a professional press and precise bolt tightening.
How much does a repair cost and is it possible to save money?
The cost of repairs depends on whether you choose original spare parts or analogues, as well as on whether you do the work yourself or contact a service center. Replacing one silent block in the service will cost an amount including labor and materials, which can be comparable to the price of the lever assembly itself in some cases.
If you have the necessary tools and skills, doing the replacement yourself can save you a significant amount of money. The main costs will be the purchase of high-quality spare parts and the rental of a hydraulic press. Also be sure to budget for new bolts and lubricants.
Saving on cheap spare parts can lead to the fact that after six months you will have to disassemble the suspension again. It’s better to buy quality parts once and forget about the problem for several years than to constantly spend money on minor repairs. For the Nissan Qashqai J10 model, it is critical to use silent blocks with the correct rubber hardness index, otherwise the suspension will become too soft or hard.
Frequently asked questions and answers
Is it possible to replace only one silent block on one side?
This is technically possible, but not recommended. If one silent block is worn out, it means that the second one on this lever, and both on the opposite side, are in a similar condition. It is better to change them as a set to avoid suspension imbalance.
Do I need to change the levers if the silent blocks are intact, but there is play in the bolts?
Yes, if the bolt threads are torn off or the seats in the levers are broken, replacing only the silent blocks will not help. In this case, it is necessary to replace the lever assembly or repair it with welding of bushings.
How often do you need to check the condition of silent blocks?
It is recommended to carry out a visual inspection of the suspension at each maintenance, that is, once every 10–15 thousand kilometers. If characteristic knocking noises appear, diagnostics should be carried out immediately.
Can I use regular press-fitting lubricant?
No, regular lubricant can corrode the rubber. Use only special silicone grease or soap solution. Never use engine oil or grease to install rubber-to-metal joints.
How long does it take to replace silent blocks?
If you have professional equipment and experience, the process takes from 2 to 4 hours per car. Without a press and using improvised means, the time can increase to 6–8 hours.
