Crossover suspension Nissan Terrano experiences enormous loads when operating in our off-road conditions and in city traffic. Some of the most loaded elements are silent blocks, which provide an elastic connection of the levers with the subframe and hubs. Their good condition directly affects handling, ride comfort and the safety of all passengers.
Many owners Nissan Terrano are faced with the fact that a knocking sound in the front or rear suspension appears suddenly, although visually the rubber may seem intact. In fact, inner metal bushing failure or rubber-to-metal joint delamination occurs from the inside, making early diagnosis critical to avoiding costly undercarriage repairs.
Design features and role in suspension
The silent block is a part consisting of two metal bushings and a rubber insert between them. In suspension Nissan Terrano These elements serve as dampers, dampening vibrations transmitted from the wheels to the body. They also allow the suspension arms to change angle while the springs and shock absorbers operate without causing harsh friction.
In the front suspension Nissan Terrano levers of complex shape are used, where silent blocks are responsible for maintaining the wheel alignment geometry. If you notice uneven tire wear, the problem often lies in worn rubber-to-metal joints that no longer hold the lever in a given position.
The rear suspension of this crossover is also full of similar elements, especially in the mounting location of the rear beam or multi-link system (depending on the year of manufacture). Here they compensate for longitudinal and lateral forces during acceleration and braking, ensuring a smooth ride even on uneven roads.
Main signs of wear and diagnostics
You can determine that silent blocks require replacement based on a number of characteristic symptoms that cannot be ignored. The first and most reliable sign is the appearance of dull knocks or squeaks when driving over uneven surfaces, especially at low speeds. These sounds can come from either the front or rear of the car.
When driving on a straight road, you may feel vibration on the steering wheel or in the floor of the cabin, which intensifies during acceleration. This suggests that the rubber insert has lost its shock-absorbing properties, and metal has begun to come into contact with metal, transferring all the unevenness of the road to the body.
A visual inspection of the suspension should be carried out on a platform or lift. Pay attention to the presence of cracks on the rubber surface, its tears or bulging. Even if visually everything looks normal, check the play of the levers using a pry bar: if the lever moves with a noticeable gap, it means silent block lost its rigidity.

Selection of quality spare parts for Terrano
The auto parts market offers a huge selection of options for Nissan Terrano, and choosing the right manufacturer is the key to longevity of the repair. Original parts from Nissan They have ideal geometry and rubber composition, but their cost often exceeds the budget of the average car owner.
Analogs from trusted brands such as Febi Bilstein, CorTEC or Lemförder, often offer the best value for money. These manufacturers use rubber varieties that are more resistant to oil and temperature, which is especially important for our harsh winters and hot summers.
Budget Chinese options should be considered with caution. Cheap rubber quickly hardens in the cold or softens in the heat, which leads to rapid failure. In such parts, the vulcanization technology is often violated, which is why the rubber peels off from the metal after just a few thousand kilometers.
⚠️ Attention! Never skimp on silent blocks, as their failure can lead to destruction of the suspension arm and complete loss of control of the car while moving.

Tools and preparation for replacement
Replacing silent blocks is a procedure that requires a certain set of tools and physical strength. You will need a hydraulic or screw press to press out the old bushings and press in the new ones. Without this tool, the task becomes almost impossible in a garage.
Also prepare a set of sockets, a torque wrench to tighten the fasteners to the correct torque, a pry bar to release the levers, and silicone-based lubricant. Don't forget about personal protective equipment: glasses and gloves are required when working with suspension springs.
The vehicle must be securely supported on stands to eliminate the risk of falling. Remove the wheel and unscrew the bolts securing the lever to the hub and subframe.
☑️ Replacement tools
Step-by-step replacement instructions
The process begins by removing the lever from the car. Unscrew the bolt attaching to the steering knuckle and the two bolts attaching to the subframe. Carefully remove the lever without damaging adjacent suspension elements and the brake hose.
Secure the lever in a vice or press. Install a mandrel of the appropriate diameter and slowly press out the old silent block. If the rubber is stuck to the metal, you can use a penetrating lubricant, but avoid harsh solvents that can damage the metal.
Before installing a new part, clean the seat from rust and dirt. Apply a thin layer of silicone grease to the outside of the new bushing to make pressing easier. Install the new part strictly in the center and press it in until it stops, making sure that it does not warp.
- 🔧 Use only a working hydraulic press for work
- 🛡️ Clean the seat from corrosion before installation
- 🛢️ Lubricate the new part with silicone grease for ease of installation
- ⚙️ Make sure there is no distortion when pressing the bushing
What are the dangers of improperly tightening the lever bolts?
If you tighten the arm mounting bolts while the car is hanging in the air, the rubber of the silent block will be permanently twisted into an unnatural position. This will lead to its rapid destruction after just a few hundred kilometers. Always tighten fasteners with the weight of the vehicle when the suspension is compressed under load.
To make it easier to press in new silent blocks, you can use a soap solution, but silicone grease is preferable, since it is not washed off with water and protects the rubber from aging.
Common mistakes and important nuances
One of the most common mistakes is trying to replace the silent block without removing the lever from the car. In conditions of a tight engine compartment, this is almost impossible to do efficiently, and there is a high risk of damaging adjacent components or not providing the correct pressing force.
Another mistake is ignoring the tightening torque of the bolts. Many car owners simply “pull” them by hand. This is unacceptable, since incorrect force can lead to thread breakage or insufficient fixation of the lever, which can lead to it breaking off during movement.
It is also not recommended to replace only one silent block if there is obvious wear. If one part fails, it means that all the others in the suspension worked for the same amount of time. It is better to change the complete set of levers or all the silent blocks at once to avoid an imbalance in the suspension.
⚠️ Attention! After replacing the silent blocks with Nissan Terrano It is imperative to undergo a wheel alignment procedure, since the suspension geometry may change.
Replacement of silent blocks should be carried out only with the lever removed and using a press, and fasteners should be tightened only with the suspension loaded.

Operation after repair
After completing the work and replacing all worn elements, it is recommended to monitor the condition of the suspension for the first 500-1000 km. Avoid sudden starts and extreme driving to allow the new tires to “break in” and take the correct shape.
Check the tightness of the bolts after 1000 km, as during the first operation under load the threaded connections may loosen slightly. If you notice any unusual sounds or vibrations, immediately contact the service for re-diagnosis.
Regular condition check silent blocks with each maintenance will extend the life of the suspension Nissan Terrano and avoid sudden breakdowns on the road. Timely replacement is a guarantee of your safety and comfort for many years.
⚠️ Attention! Replacing silent blocks without subsequent wheel alignment adjustment is strictly prohibited, as this will lead to rapid tire wear and deterioration of vehicle stability.
How often do you need to change silent blocks on a Nissan Terrano?
The average resource of original silent blocks is 80-100 thousand kilometers. However, when used in off-road conditions or on bad roads, this period can be reduced to 40-50 thousand km. Regular diagnostics are mandatory at every maintenance.
Is it possible to replace the silent block without a press?
It is theoretically possible to use powerful clamps and improvised means, but this is extremely risky and labor-intensive. Without a professional press, it is difficult to ensure uniform pressure, which can lead to misalignment or damage to the new part.
Do I need to change the entire lever or just the silent block?
If the lever does not have mechanical damage (cracks, severe corrosion), replacing only the silent block is more economical. However, many craftsmen recommend changing the lever assembly to save time and guarantee build quality.
Does replacing silent blocks affect wheel alignment?
Yes, replacing silent blocks changes the suspension geometry. After replacement, it is imperative to visit a wheel alignment stand to adjust the wheel alignment angles, otherwise the tires will wear unevenly.
