Operation Nissan Almera G15 in Russian road conditions it inevitably leads to wear of suspension elements. One of the most common problems faced by owners of this model is the failure of shock absorber support bearings. The malfunction of this unit is manifested by a characteristic knocking sound when going over uneven surfaces and difficulty steering at low speeds.
Ignoring the symptoms can cause accelerated wear of other chassis components, including springs and shock absorbers. Timely diagnosis and replacement support bearing allow you to return the car to factory smoothness and safety. In this article we will analyze the signs of breakdown, criteria for selecting spare parts and a detailed repair process.
Many car enthusiasts put off visiting a service center, hoping that the knocking noise will go away on its own. However, the mechanics of the process is such that the destruction of the rubber-metal hinge or bearing cage occurs like an avalanche. If you hear a crunching sound when turning the steering wheel in place, this is a direct signal to action.
Symptoms and diagnostics
The first and most obvious sign of a problem is a specific sound. When driving over small irregularities, for example, speed bumps, you hear a dull knock, which is localized in the front part of the body. This sound becomes louder when driving at low speeds and is often accompanied by vibration in the steering wheel.
The second important symptom is related to management. If, when parking or turning around, the steering wheel turns with force, and then returns to its original position with a sharp click, it means the support is jammed. In good condition, the steering wheel should rotate smoothly, without jamming or sudden changes in resistance.
Sometimes the problem is disguised as a malfunction of other components. To accurately determine the source of the noise, it is necessary to conduct a thorough diagnosis. Inspect front pillar for shock absorber leaks or spring deformation, since these defects often accompany support failure.

- 🔄 Tight steering wheel rotation with periodic clicks.
- 🚗 The car pulls to the side when driving straight.
- 📉 Wear of rubber in the place where the support is attached to the body.
Selection of quality spare parts
The auto parts market offers a huge range of products, from original parts to budget analogues. For Nissan Almera G15 It is critically important to choose reliable brands, since you cannot save on this point. Cheap Chinese bearings may not withstand even a couple of thousand kilometers of operation.
Original spare parts from Nissan They have ideal geometry and quality materials, but their price is often overpriced. A good alternative are proven suspension manufacturers such as Kayaba, SNR or Lemforder. These brands often supply parts to automakers' assembly lines.
Pay attention to the package when purchasing. Often a new mounting ring and lock nut are included with the bearing. After dismantling, the old nut may not be tightened with the required torque, which will lead to the unit becoming loose. The use of a reusable nut when replacing a support is strictly prohibited.
| Brand | Product type | Approximate price | Resource (km) |
|---|---|---|---|
| Nissan (OEM) | Original | High | 100 000+ |
| Kayaba | High-quality analogue | Average | 80 000 - 100 000 |
| SNR | European standard | Average | 70 000 - 90 000 |
| Budget analogues | Economy segment | Low | 20 000 - 40 000 |
⚠️ Attention: Buy spare parts only from official dealers or large chain stores to avoid counterfeits. Counterfeit bearings often have defects in the cage, which leads to their rapid destruction.

Necessary tools and preparation
Before starting work, make sure that you have all the necessary tools. A standard garage kit may not be suitable, since working with the suspension requires specific equipment. You will definitely need a spring remover to safely release the strut assembly.
Also have a torque wrench ready to tighten critical connections. Without this tool, it is impossible to ensure proper tightening of the shock absorber rod top nut. Incorrect tightening torque can lead to thread stripping or bearing failure during operation.
- 🛠️ Set of socket heads and ratchet (10, 12, 14, 17, 19 mm).
- 🔧 Spring remover (required!).
- 🔨 Hammer and punch for knocking out pins.
- ⚙️ Torque wrench (rod tightening torque 35-45 Nm).
☑️ Preparation for replacement
Rack removal process
It is better to do the work on a lift or inspection pit. First you need to loosen the shock absorber rod nut while the wheel is on the ground. This will prevent the rod from twisting when unscrewing. Use a 14 mm socket wrench and a hex wrench to hold the rod.
After removing the wheel, unscrew the bolts securing the lower part of the strut to the steering knuckle. They are usually 17 or 19 mm in size. Be careful not to damage the brake hose and ABS sensor when removing the bolts. Also disconnect the handbrake cable if it is attached to the strut.
Unscrew the three nuts securing the upper support to the body in the engine compartment. Carefully remove the entire rack assembly. If the post is stuck, use a penetrating lubricant and gently tap the joints.
What to do if the stem nut does not unscrew?
If the nut does not budge, try heating it with a hair dryer or blowtorch. You can also use a special tool to hold the rod. In extreme cases, if the rod rotates, you will have to fix it with a vice through a wooden spacer, but this must be done extremely carefully so as not to damage the threads of the shock absorber.
Disassembling and replacing the bearing
Clamp the removed stand in a vice. Install the spring remover so that it compresses the spring evenly on both sides. Squeeze until the tension on the upper support disappears. This is a critical safety step.
Unscrew the rod nut and remove the upper support along with the bearing. Inspect the rubber support pad - if it has cracks or tears, it also needs to be replaced. Remove the old bearing from the top spring cup. Often it fits very tightly and requires careful knocking out.
Clean the seat from dirt and rust. Install the new bearing, making sure it is seated all the way. Assembly is carried out in reverse order. Don't forget to install new snap rings and stem nut.
Before you begin compressing the spring, mark the spring coils and strut cups with chalk so that when reassembling, the spring will be in the same position as before. This will maintain the correct suspension geometry.
⚠️ Attention: Never try to release a spring without a special puller. This could cause the spring to fly out and cause serious injury or property damage.
Proper installation of the spring in the strut cup is critical to comfort and safety. Incorrect position can lead to spring sagging and disengagement.
Installation and final check
Install the assembled rack onto the vehicle. First secure it at the top by tightening the nuts on the body. Then insert the bottom into the steering knuckle and tighten the bolts. Do not tighten the knuckle bolts to maximum torque until the wheel is on the ground.
Put the wheel on and lower the car. Tighten the lower strut bolts to the torque specified in the owner's manual (usually about 100-120 Nm). Also check the tightness of the shock absorber rod nut - this is the most important connection.
After replacing both bearings, be sure to visit the wheel alignment stand. Replacing the bearings may slightly change the wheel alignment, resulting in uneven tire wear. Checking the suspension geometry will complete the repair process.
- ✅ Check the tightness of all bolts and nuts after 500 km.
- 🎯 Go through a wheel alignment to correct wheel alignment angles.
- 🧼 Clean the engine compartment from dirt and traces of grease.
- 🔍 Check the operation of the steering during a test ride.
Frequently asked questions and answers
Can only one bearing be replaced?
It is advisable to change both bearings at the same time, even if the second one does not knock as much. They have the same mileage and operating conditions, so the wear of the second unit is already close to critical. This will save time and money on re-disassembly in the near future.
Do I need to change the shock absorber struts when replacing the mounts?
If the shock absorbers are in good condition and have no leaks, they can be left. However, often when the support wears out, the shock absorber itself suffers. It is recommended to diagnose the struts: if they “sell” or have traces of oil, it is better to replace them as an assembly.
How long does it take to replace?
An experienced technician spends about 30-40 minutes replacing one bearing. For two wheels the work will take approximately 1.5 hours. A beginner without experience and a special spring remover may need 3-4 hours.
What happens if you drive with a faulty support?
Long-term operation with a faulty support will lead to destruction of the body shell where the support is attached. Repairing this damage will cost significantly more than replacing the bearing and will require welding.
Regular inspection of the suspension and timely replacement of worn parts is the key to safe driving. Do not put off repairs until later, because not only the comfort, but also the controllability of your vehicle depends on the condition of the support bearings. Nissan Almera G15.
