Operation Nissan Almera Classic often reveals weak points in the suspension, one of which is the front shock absorber strut. In the design of this unit, a critical element is support bearing, which is responsible for the smooth rotation of the shock absorber rod when turning the steering wheel. Without its proper operation, the car loses maneuverability, and the driver hears characteristic knocks and squeaks even at low speed.
Many owners ignore early symptoms of a malfunction, considering them to be the norm for a used car. However, the delayed replacement support bearing can lead to the destruction of the shock absorber cup, deformation of the body and, in the worst case, a complete loss of control when cornering. For model Nissan Almera Classic This problem is especially acute due to the design features of the front suspension and the quality of the original components.
Functional purpose and design of the unit
The support bearing (or support unit) performs a dual function: it absorbs axial loads from the weight of the vehicle and ensures free rotation of the shock absorber rod when the wheels turn. B Nissan Almera Classic this element is located in the upper part of the mudguard of the engine compartment and connects the shock absorber strut to the body through a cup.
Structurally, the unit is a metal housing, inside of which there is a ball bearing, filled with special lubricant and protected by a rubber boot. This one rolling bearing allows the stand to rotate with the wheel without creating friction against the stationary body. When the rubber part fails, moisture and dirt get inside, which instantly kills the mechanism.
It is important to understand that Nissan Almera Classic The support bearing and upper shock mount are often sold together, even though they are technically different parts. Replacing only the bearing without replacing the rubber cushion may not give the desired result, since the old rubber has already lost its shock-absorbing properties.
β οΈ Attention: On cars with a mileage of more than 100,000 km, replacing only the metal part of the bearing without replacing the rubber upper support often leads to the reappearance of knocking after 2-3 thousand kilometers.
Main signs of wear and diagnostic methods
Understand that support bearing on Nissan Almera Classic requires replacement, due to a number of specific symptoms that are difficult to confuse with other suspension faults. The most obvious sign is a squeaking or crunching sound when turning the steering wheel in place or at low speed, especially when the car is parked on an uneven surface.
When driving the car, you can hear dull knocks in the area of the front pillars, which intensify when driving over uneven surfaces. This occurs because the damaged bearing cannot hold the shock absorber rod in the correct position, and it begins to bang against the support housing. Also pay attention to how the steering wheel behaves: if it returns to a straight position with difficulty or with a delay, the problem is almost certainly in the support assembly.
For an accurate diagnosis, you need to perform a simple test. Open the hood, ask an assistant to turn the steering wheel left and right, and put your hand on the upper shock absorber cup (in the mounting area). If you feel vibration, beating or hear a knock that is transmitted to the body, the unit requires immediate replacement.

Selection of quality spare parts: original or analogues
Spare parts market for Nissan Almera Classic oversaturated with offers, and choose a reliable one support bearing it can be difficult. The original part from Nissan (part number usually starts with 54320) is distinguished by high build quality and long-lasting lubrication, but is quite expensive. In addition, the original often comes complete with a new rubber cushion, making replacement more expensive but reliable.
If your budget is limited, you should pay attention to proven analogue manufacturers. Brands like KYB, Sachs or SNR They offer products that are not inferior in their characteristics to the original, and sometimes even surpass it due to improved materials. However, cheap Chinese analogues often have play in the bearing after several thousand kilometers.
When purchasing, be sure to check the integrity of the packaging and the presence of a protective boot. On Nissan Almera Classic It is critical that the bearing is completely sealed, since moisture entering the mechanism leads to rapid oxidation of the balls and jamming of the assembly.
| Manufacturer | Product type | Approximate resource (km) | Features |
|---|---|---|---|
| Nissan (Original) | Bearing assembly with support | 100 000+ | Perfect compatibility, high price |
| KYB (Kayaba) | Support node | 80 000 - 100 000 | Great quality, popular choice |
| Sachs | Support bearing | 70 000 - 90 000 | High rigidity, long lasting lubrication |
| Techline | Set of supports | 60 000 - 80 000 | Budget option, decent quality |
When purchasing a support bearing, always ask the seller to check that there is no play in the assembly by shaking it slightly with your hands. If there is a noticeable movement, the part is defective or in storage.
Preparation for replacement and necessary tools
Replacement support bearing on Nissan Almera Classic - This is a job that requires special tools and a certain skill. You will need a jack, stands for the car (never work under the car with just a jack!), a set of socket wrenches and, most importantly, a shock absorber spring remover.
It is impossible to dismantle the upper support without a spring remover, since the spring is under enormous tension. Attempting to remove the stem nut without compressing the spring will result in parts flying and serious injury. Also, be sure to prepare WD-40 or a similar liquid lubricant to treat the soured mounting bolts.
Before starting work, you must secure the car on a level surface, turn on the handbrake and place chocks under the rear wheels. If you plan to replace bearings on both sides at once, prepare a storage area for the removed parts and a new set of spare parts.
- π οΈ Set of socket heads (14, 17, 19 mm and extensions).
- π¨ Shock absorber spring remover (required!).
- βοΈ Jack and reliable stands (goats).
- π§ͺ Liquid lubricant (WD-40, Liqui Moly) for rusty bolts.
βοΈ Preparation for replacement
Step-by-step instructions for dismantling and installation
The replacement process begins with removing the wheel and unscrewing the bolts securing the caliper, which must be suspended on a wire so as not to damage the brake hose. Next, the bolts securing the lever to the steering knuckle are unscrewed, after which the shock absorber strut is removed from the hub.
The removed strut must be clamped in a vice and a spring remover installed. Compress the springs until the tension on the upper support disappears. Only after this can you unscrew the shock absorber rod nut. Be careful: the rod may rotate with the nut, so it must be secured with a hexagon.
After removing the old support, clean the installation site on the body from dirt and rust. Install new support bearing, making sure it is oriented correctly (usually there is a mark or a specific shape). Reassemble the assembly in reverse order, being sure to tighten all bolts to the recommended torque.
β οΈ Attention: When assembling the rack, the spring must be in its seat with the ends matching exactly. If the spring comes off when the puller is being released, body damage or personal injury may result.
How to tighten the rod nut correctly?|The shock absorber rod nut must be tightened to a torque of 50-60 Nm, but only after the strut has been installed on the car and loaded with the weight of the body. Suspended tightening can lead to thread stripping or premature bearing failure.-->
Operation after replacement and prevention
After successfully installing the new support bearings on Nissan Almera Classic the car should become more obedient, and the steering wheel should become lighter. Check the suspension by driving on an uneven road. If there are no extraneous sounds and the steering wheel returns to the center smoothly, then the work has been done efficiently.
To extend the service life of new components, it is recommended to regularly inspect the shock absorber boots. If the rubber is damaged, dirt gets inside, which destroys not only the shock absorber itself, but also the support bearing. Timely replacement of the boot can save expensive components.
Avoid aggressive driving on bad roads. Impacts on holes create a colossal impact load on support bearing, which can lead to its destruction even with new quality. Taking care of your suspension is the key to safety and comfort over many years of use.
β οΈ Attention
The service life of the support bearing directly depends on the condition of the shock absorber boot - if it ruptures, the service life of the unit is reduced by 3-4 times.
How often do you need to change support bearings on a Nissan Almera Classic?
On average, the service life of support bearings is 60,000 - 80,000 km, but this depends on the quality of the roads and driving style. It is recommended to check their condition at every oil change or once a year.
Is it possible to replace only one bearing if it only knocks on one side?
Technically it is possible, but experts strongly recommend changing both nodes at the same time. Wear on the right and left sides occurs evenly, and if one bearing fails, the second will soon follow suit. This will save time and money on a repeat visit to the service.
Is it necessary to do a wheel alignment after replacing the support bearings?
Yes, definitely. Although replacing the support bearing itself does not change the wheel alignment dramatically, the process of removing and installing the strut can throw off the alignment. In addition, replacement often affects other suspension components, making a wheel alignment necessary.
What happens if you drive with a faulty support bearing?
Driving with a worn bearing leads to knocking noises, poor handling and accelerated wear of other suspension elements. In critical cases, this can lead to steering jamming or destruction of the shock absorber cup on the body.
