Car suspension Nissan Almera Classic experiences enormous loads, especially on Russian roads with their potholes and uneven surfaces. Front shock absorbers play a key role in comfort and safety by dampening body vibrations and keeping the wheels in contact with the asphalt. When these elements fail, the driver notices a deterioration in handling, extraneous knocking when passing obstacles and an increase in braking distance.
Ignoring signs of wear can lead to more serious damage, such as broken control arms or failed wheel bearings. Timely replacement suspension components is not just a matter of comfort, but a necessity to preserve the life of the car. In this article we will analyze in detail the process of dismantling and installing new shock absorbers so that you can do the job efficiently and safely.
Suspension symptoms and diagnostics
You can determine that the front shock absorbers require replacement based on a number of characteristic signs. The most obvious signal is the appearance of dull knocks or knocks in the front of the car when driving over bumps, speed bumps or potholes. These sounds can come from either the driver or passenger side and usually increase in intensity as driving speed increases.
In addition to acoustic signals, pay attention to the behavior of the car on the road. If Nissan Almera Classic It becomes less stable in turns, the body rolls heavily, and when braking sharply, the nose of the car drops sharply downwards, these are sure signs of a loss of shock-absorbing properties. It is also worth checking visually: the presence of oil leaks on the shock absorber body indicates a violation of the tightness and the need for replacement.
- π The appearance of characteristic knocks and squeaks in the front suspension when driving over uneven surfaces.
- π Increased braking distance and loss of stability during emergency braking.
- π Strong body roll in turns and βfloatingβ of the car when driving in a straight line.
- π§ Visible oil smudges on the shock absorber rod or body.
β οΈ Attention: Operating a car with faulty shock absorbers is strictly prohibited, as this can lead to a complete loss of controllability in a critical situation, especially on wet or icy surfaces.
For an accurate diagnosis, you can perform a simple test: press on the front corner of the body and release. If the car rocks once and stops, everything is fine. If the oscillations continue for several cycles, it means that the shock absorber cannot cope with the damping of the spring energy. Regular inspection suspension will identify the problem at an early stage.
Necessary tools and selection of spare parts
Before you begin, you need to prepare the entire set of tools and spare parts. For Nissan Almera Classic You will need a standard set of wrenches, including 12, 14, 17, 19 and 22 millimeter sockets. It is imperative to have a jack and reliable stands (goats), since working under the machine on a jack alone is life-threatening.
Choosing shock absorbers is a critical step. Both original parts and high-quality analogues from leading manufacturers are suitable for this car. Installing a new part next to an old one will cause uneven wear and unbalance the suspension.
- π§ Set of keys and sockets (including ratchet and wrench).
- π οΈ Spring remover (required for safe disassembly of the rack).
- βοΈ New shock absorbers (preferably with springs or ready-made struts).
- 𧴠WD-40 lubricant or equivalent for processing threaded connections.
It is important to note that removing the upper shock mount often requires a special tool to compress the spring. Attempting to do this manually or using improvised means may result in injury due to the sudden straightening of the spring. Security when working with spring mechanisms should be in first place.
| Part type | Recommended Brand | Approximate service life | Features |
|---|---|---|---|
| Original (Nissan) | Nissan / Kayaba | 60-80 thousand km | Perfect compatibility, high price |
| Analogue (Gas-oil) | Kayaba Excel-G | 50-70 thousand km | Optimal balance of price and quality |
| Analogue (Oil) | Sachs, Monroe | 40-60 thousand km | Soft ride, but less resistance to stress |
| Analogue (Gas) | Monroe Gas-Magnum | 70-90 thousand km | Stiff suspension, high cross-country ability |
β οΈ Warning: Never use a spring remover that is damaged or cracked. This could cause the tool to break under load and cause serious injury.

Preparing the car and removing the wheels
The first step is to prepare the work area. The car should be parked on a flat, hard surface, preferably on an inspection hole or overpass, to provide easy access to the top of the shock absorber in the engine compartment. Secure the rear wheels with chocks and engage neutral or park if it's an automatic.
Before lifting the machine, loosen the front wheel bolts, but do not unscrew them completely. Raise the car with a jack, install safety stands under the sills or special lifting points. Only then can the wheels be completely removed. This will ensure you safety and freedom of movement when working with the suspension.
Inspect the condition of other suspension elements: levers, silent blocks and anti-roll bar. If you see significant wear on these parts, it makes sense to replace them at the same time as the shock absorbers. This will save you time in the future by having to disassemble the suspension again. Complex repair always more profitable and faster.
βοΈ Preparation for dismantling
Removing and disassembling the shock absorber strut
The process begins by removing the upper shock absorber mount. In the engine compartment, unscrew the three nuts securing the support to the body. If the nuts are stuck, use a penetrating lubricant and gently hit the head of the bolt with a hammer to knock off the carbon deposits. Be careful not to damage the body paint or engine compartment components.
Next, move to the bottom of the rack. Disconnect the stabilizer bar link from the shock absorber. Then loosen the bolt securing the shock absorber to the steering knuckle. After unscrewing all the fasteners, carefully remove the shock absorber strut assembly from the wheel arch. You now have access to disassemble the assembly.
- π© Unscrew the three nuts of the upper support in the engine compartment.
- π Disconnect the stabilizer link from the shock absorber body.
- π§ Loosen the lower bolt securing the steering knuckle.
- π¨ Carefully remove the strut, avoiding damage to the brake hose.
If you are replacing only the shock absorber and not the strut assembly, you will need a special spring compressor puller. Place the tool on the spring from opposite sides and tighten it smoothly until the spring stops pressing on the support cup. After this, you can unscrew the top nut of the rod and disassemble the assembly.
β οΈ Warning: Wear safety glasses and gloves when working with compressed springs. Sudden release of the spring can cause serious injury to the hands and eyes.
Installing new shock absorbers and assembling the unit
Before installing new parts, inspect them carefully. Make sure the shock absorber has no external damage and the spring is properly shaped and covered. If you are replacing an entire rack assembly, the process is simplified: just install the finished unit in place. If you are only changing the shock absorber, transfer the upper support, boot and bump stop to the new element.
Assemble the assembly, following the correct sequence: rod, spring, bump stop, boot, upper support. It is important to install the spring so that its end fits exactly into the groove of the lower body cup. Misalignment of the spring can lead to its jumping and an emergency situation. Precise installation all elements are critical to the durability of the suspension.
After assembling the rack, install it on the car. Insert the rod into the hole in the upper support and tighten the nuts. Then screw the lower part of the shock absorber to the steering knuckle. Tighten all bolts to the recommended torque. Use a torque wrench to avoid over-tightening the threads and damaging the parts.
| element | Tightening torque (Nm) | Note |
|---|---|---|
| Shock absorber rod nut | 35-40 | Tighten with compressed spring |
| Knuckle bolt | 90-100 | Use a new nut |
| Upper support nuts | 20-25 | Cross tightening |
| Stabilizer link | 25-30 | Do not overtighten to avoid breaking the hinge. |
Be sure to install the wheel and lower the vehicle to the ground. Only after the car is completely lowered onto the wheels can you finally tighten the lower bolt securing the shock absorber to the knuckle. This will prevent thread distortion and ensure proper seating of the part. Final puff must be carried out strictly under load.
Functionality check and wheel alignment
After installing new shock absorbers, it is necessary to check the operation of the suspension. Sit on the hood of the car several times to make sure there are no extraneous sounds and smooth movement. Drive the car at low speed and check the steering response and body stability. If everything is in order, you can proceed to the final procedures.
One of the most important procedures after replacing shock absorbers is wheel alignment. Any intervention in the suspension geometry, including removing the steering knuckle or control arms, changes the wheel alignment angles. Without adjusting these parameters, the tires will wear unevenly, and the steering wheel may become crooked even when driving straight.
- π Check for oil leaks on new shock absorbers.
- π Test your handling on a safe section of the road.
- π Be sure to visit the wheel alignment stand to correct the angles.
- π Inspect your tires for uneven wear.
Ignoring the wheel alignment procedure can lead to rapid tire wear and poor directional stability. The cost of this service is not comparable to the risks associated with incorrect suspension geometry. Professional setup will return the car to factory handling characteristics.
Do shock absorbers need to be replaced in pairs?
Yes, shock absorbers are always replaced in pairs on the same axis. The different wear and stiffness characteristics of the left and right sides will cause the vehicle to become unbalanced, especially when braking and cornering.
Is it possible to change only one shock absorber?
Technically this is possible, but it is highly not recommended. The difference in stiffness and rebound between the old and new shock absorber will create a misaligned suspension, which will negatively affect handling and safety.
How long does it take to replace front shock absorbers?
If you have the necessary tools and experience, replacing two front shock absorbers takes 2 to 4 hours. If this is your first time doing this, spend more time learning the details and working with rusty bolts.
What to do if the stem nut is spinning?
To fix the rod, use a special hex wrench or a vice with soft jaws. Do not attempt to pinch the stem with pliers as this will damage the chrome plating and cause oil leakage.
Is it possible to drive the car immediately after the replacement?
Yes, you can drive, but with caution. For the first 500 kilometers, avoid sudden maneuvers, emergency braking, and driving through deep holes so that the parts can break in and secure in the correct position.
