Many crossover owners Nissan Qashqai first generation (J10) are faced with a characteristic knocking noise in the front suspension, which is often ignored until a critical moment. The cause of this sound is most often worn out silent blocks, made of a rubber-metal compound, which eventually hardens and cracks under the influence of reagents and temperature changes. Complete replacement of the lever assembly is a quick but extremely expensive solution to the problem, while replacing only the rubber bushings can save a significant amount of money, provided you have the right tools.
The suspension restoration process Nissan Qashqai requires care, since incorrect pressing of new elements can lead to their rapid destruction or disruption of wheel alignment. In this article we will look in detail at how to replace it yourself. silent blocks front levers, what tools will be needed and what nuances you should pay special attention to during work.
Preparation of tools and selection of necessary spare parts
The success of the entire event Nissan Qashqai J10 directly depends on how well you prepare for work. You will need a set of powerful tools, since old silent blocks often stick to the metal and require considerable effort to remove. A standard set of keys will not help here; you need a hydraulic or powerful mechanical press.
- 🔧 Hydraulic jack and reliable stands for the car
- 💥 Powerful silent block remover or hydraulic press
- 🔨 Heavy sledgehammer and chisel set for removing old bushings
- 🛢 WD-40 liquid or similar penetrating compound
When choosing spare parts for Nissan Qashqai It is important to understand the difference between original parts and high-quality analogues. Original silent blocks from Nissan They last a long time, but are not cheap. Branded products are a good alternative. Febi, Mapco or Corteco, which often have improved rubber compound characteristics.
Do not try to save money by buying cheap Chinese bushings without a brand - they may not withstand even a couple of thousand kilometers, which will lead to repeated dismantling of the lever. It is best to check whether the kit contains special mandrels for pressing, which often come in a set with high-quality silent blocks.
The stage of dismantling the lever and removing the old bushings
The first step is to safely lift the vehicle and remove the front wheel. After this, you need to unscrew the fastening bolt anti-roll bar to the lever, as well as the ball joint nut. The ball joint can be carefully pressed out with a pry bar, but this must be done carefully so as not to damage the boot.
The most difficult moment is to unscrew the bolt securing the front silent block to the subframe. Often the nut gets stuck tightly, and a powerful wrench or impact wrench is required to unscrew it. If the bolt does not budge, treat the joint generously with penetrating lubricant and allow it time to work.
⚠️ Attention: When unscrewing the bolts securing the arm to the subframe, do not unscrew them completely at once! Leave a couple of turns so that the lever doesn't fall to the ground when you loosen the rest of the fasteners. This will prevent damage to the brake hoses and wiring.
After removing the lever from the car, proceed to dismantling the old silent blocks. If you don't have a press, you can use the chisel pressing method, but this is risky: you can damage the seat in the lever itself. The best option is to use a puller that applies even pressure on the bushing.
- 🔨 Carefully knock out the inner metal sleeve from the silent block body
- 🛢 Generously coat the remaining rubber with penetrating lubricant.
- 💥 Use a puller to press the rubber part out of the aluminum body
If you use a sledgehammer, try to hit exactly in the center of the metal cage so as not to deform the aluminum body of the lever. Any dent or misalignment of the seat will make it impossible to properly install the new part.

The process of pressing in new silent blocks
Installing new bushings requires maximum precision. On Nissan Qashqai J10 The front and rear silent blocks have different designs and orientations, so they cannot be confused. Before starting work, thoroughly clean the seats from dirt, rust and old rubber residues.
Use the special mandrels that come with the new parts. They ensure even distribution of force and prevent rubber distortion. If you press directly on the rubber part, it may tear or become deformed, causing rapid failure.
☑️ Pressing procedure
For better sliding of rubber on metal, you can lubricate the seat with soapy water. This is a classic technique that makes the installation process easier without the use of aggressive oils that can destroy the rubber structure over time. The main thing is not to overdo it so that the part does not jump out of its seat.
⚠️ Attention: Pay attention to the direction of installation of the silent block! Often there is a mark or protrusion on the body that should point in a certain direction. If the orientation is mixed up, the lever will not work correctly and the suspension will start to knock even with new parts.
Check that the new bushing is flush with the lever body or has the clearance provided by the design. Incorrect seating depth can cause the mounting bolt to rest against the rubber rather than the metal sleeve, creating unnecessary stress on the structure.
What to do if you don't have a press?|If you don't have access to a hydraulic press, you can use a long bolt, nuts, and washers as a basic puller. Assemble the structure so that the nut presses on the mandrel, and the bolt rests on the opposite side of the lever. By tightening the nut with a wrench, you will create the necessary force for pressing.-->
Installing the lever back on the car
After all silent blocks are installed, you can begin installing the lever on Nissan Qashqai. Raise the arm with a jack so that the holes line up with the subframe. Insert the bolts, but do not fully tighten them.
It is important to tighten the silent block bolts only under load, that is, when the car is on its wheels. If you tighten them by weight, the rubber bushings will twist when driving, which will lead to their rupture after a short period of time. This is a critical point that beginners often ignore.
The tightening sequence is as follows
first secure the ball joint and stabilizer, then lower the car onto the wheels and only after that finally tighten the bolts securing the lever to the subframe with the required force. Use a torque wrench for accuracy.
- 🔧 Clean the bolt threads from rust before installation
- 🛢 Apply a little lubricant to the threads to protect against corrosion
- 🔨 Check the tightening torque according to the manufacturer's recommendations
Check the condition of the ball joint boots and stabilizer. If you damage them during dismantling, it is better to replace them immediately, since dirt getting inside the ball joint will shorten its service life.
Features of wheel alignment adjustment
After replacing the silent blocks of the front levers with Nissan Qashqai J10 suspension geometry inevitably changes. Even microscopic misalignment can cause uneven tire wear and poor handling. Therefore, a trip to the wheel alignment stand is mandatory.
On this crossover, adjustment of the longitudinal inclination of the steering axis (caster) and camber angle is carried out by moving the levers in the oval holes of the subframe. The technician must set the parameters within the factory tolerances so that the car does not “steer” to the side and the tires do not wear out.
If you replaced the silent blocks on only one side, adjustment is still necessary, since the difference in suspension stiffness can create discomfort when driving. Ignoring this stage often leads to complaints that the steering wheel is crooked or the car is pulled to the side.
| Parameter | Value (approx.) | Tolerance |
|---|---|---|
| Camber | -1° 30' | ± 30' |
| Toe | 0° 10' | ± 10' |
| Caster | 3° 00' | ± 30' |
⚠️ Attention: Do not try to adjust wheel alignment yourself in a garage without special equipment. Tuning errors can lead to dangerous loss of control at high speeds and rapid tire failure.
Replacing silent blocks is a job that requires patience and accuracy. If you doubt your abilities or do not have the necessary equipment, it is better to entrust this process to professionals to avoid costly rework.
After replacing the silent blocks and adjusting the wheel alignment, be sure to check the behavior of the car on the first trip. If a new knock or vibration appears, immediately return to the service center to recheck.
Common replacement mistakes and how to avoid them
One of the most common mistakes is the use of oil or grease for lubrication during pressing. The rubber from which the silent blocks are made is incompatible with petroleum products. This will cause the rubber to swell and lose its elastic properties within a few months.
Another mistake is trying to knock out the old silent block by hitting the outer ring with a hammer when it has already partially come out of the housing. This often leads to the fact that the aluminum lever body is deformed, and the new silent block simply will not fit into the seat. Deformation of the lever body makes it unsuitable for further use and will have to be replaced entirely.
It is also worth paying attention to the condition of the mounting bolts. If the thread is broken or the bolt is stretched, it must be replaced. Reusing old fasteners is unacceptable, as they may not withstand the stress of driving.
FAQ: Answers to frequently asked questions
How long does it take to replace silent blocks?
If you have experience and the right tools, replacing silent blocks on one lever takes from 1 to 2 hours. If you don’t have a press and use improvised means, the time can increase to 3-4 hours.
Is it possible to replace silent blocks without removing the lever?
This is theoretically possible if you have a long puller and a lot of free space in the hanger. However, on Nissan Qashqai J10 Access is very limited, so removing the lever completely is much easier and safer to ensure the correct position when pressing.
Do I need to change the lever if the silent block is torn?
No, if the aluminum lever housing is not cracked or deformed. Replacing the rubber bushing alone is a cost-effective and technically sound procedure that restores suspension performance.
How often do you need to change silent blocks on a Qashqai J10?
The average resource of original silent blocks is 80-100 thousand kilometers, but in conditions of bad roads and reagents they may require replacement at 50-60 thousand. Regular suspension inspections will help identify problems at an early stage.
