When considering the transmission system of a front-wheel drive vehicle, one cannot ignore such a critical element as constant velocity joint, popularly called CV joint. For owners Nissan Almera G15 (also known as Renault Logan in the B0 body), the condition of the drives is the key to not only comfort, but also traffic safety. The inner left hinge performs the function of transmitting torque from the gearbox to the axle shaft, while compensating for the vertical movements of the suspension and the operation of the differential.
Many car enthusiasts mistakenly believe that replacing a CV joint is solely a “knock” when the steering wheel is turned off, but the internal grenade has its own faults, often hidden from view. Exactly left inner CV joint on the G15 model it experiences enormous loads due to the specific engine location and suspension design. Ignoring even the slightest signs of wear can lead to jamming of the unit while driving, which is fraught with serious consequences for the car and others.
Signs of a faulty inner CV joint are often confused with suspension problems, since vibration can occur not only when turning, but also when accelerating on a straight line. If you feel a characteristic beating of the steering wheel or vibration of the body when you press the gas pedal, and when you release the gas, it disappears - this is a sure sign of wear on the internal grenades. In the case of Nissan Almera this is especially true for cars with mileage over 80-100 thousand kilometers.
It is important to understand that dust, getting inside the hinge through a damaged boot, acts as an abrasive. Metal shavings begin to grind the raceways, causing backlash. CV joint repair is practically impossible, since restoring the track geometry does not guarantee reliability, so the only correct solution is to replace the unit with a new one.
Timely diagnostics allows you to avoid costly repairs of the gearbox, since balls released from a damaged joint can damage the shafts of an automatic transmission or manual transmission. Therefore, at the first suspicion, it is necessary to conduct a visual inspection and a test drive to confirm the diagnosis.
Critical symptoms of failure and diagnostic methods
Determine the fault inner left CV joint on Nissan Almera G15 possible by a number of specific symptoms that distinguish it from wear on the external grenade. The main symptom is vibration, which is transmitted to the body and steering wheel precisely at the moment of transmission of torque, that is, when you press the gas. Unlike the outer joint, which "clicks" when turning, the inner joint often "buzzes" or creates a shake.
You need to pay attention to the vibration pattern. If it increases during acceleration and disappears when coasting or engine braking, the problem almost certainly lies in the internal tripoid. On Nissan Almera With a manual transmission, this is often accompanied by a characteristic knocking sound when changing gears when the load changes suddenly.
A visual inspection also provides a lot of information, but requires attention to detail. Check the integrity of the boot (cover) of the CV joint. If the rubber is torn, the lubricant could fly out and dirt could get inside. Even if the hinge visually seems intact, the play when rocking the shaft with your hands can be critical.
For an accurate diagnosis, you can conduct a simple test: accelerate on a flat road to a speed of 40-60 km/h, then sharply release the gas and gently press it again. If vibration appears strictly at the moment of pressing, and disappears when reset, the culprit has been found. This is a classic sign of wear and tear. tripoid internal hinge.
Review of manufacturers and selection of spare parts
Auto parts market for Nissan Almera G15 oversaturated with offers, and the choice of quality inner left CV joint can be a real challenge. Original from Nissan (or its equivalent from Renault) is usually marked according to the factory catalog and provides the best quality materials, but its price can be high. Many owners choose proven brands of chassis manufacturers.

Technical features of the G15 drive design
Drive design Nissan Almera G15 has its own unique features that must be taken into account when replacing inner left CV joint. Unlike some other models where the inner joint is simply pressed into the axle shaft, this often uses a locking ring design inside the differential housing.
This means that you will need a special tool or experience with removal pullers to remove the drive. Normal hammering can damage the transmission seal or the differential housing itself, causing transmission oil to leak. Gearbox on G15 it is very sensitive to mechanical damage during dismantling.
It's also worth noting that the left drive on this model is shorter than the right drive and runs under the engine, making it difficult to access. When replacing, it is often necessary to remove the motor guard and sometimes the motor mount to provide the necessary clearance to remove the shaft. Do not attempt this job alone unless you have a lift or hole with good access.
The lubricant inside the inner CV joint must be distributed evenly over all grooves of the tripoid. Incorrect application of lubricant can lead to rapid overheating and destruction of the unit. Use only specialized lubricants, for example, based on molybdenum disulfide, which are designed specifically for constant velocity joints.
Step-by-step replacement instructions
The process of replacing the inner left CV joint with Nissan Almera G15 requires consistency and accuracy. Start by preparing the car: place it on a level surface, raise the front end on a jack and be sure to install safety stands. Remove the wheel and unscrew the wheel bearing nut, first releasing the stopper.
Next, you need to remove the suspension arm or tie rod end to free the hub and remove the drive. Be careful: the drive may be strongly stuck to the seal. Do not use a pry bar as a lever against the transmission housing to avoid damaging the gasket or the housing itself.
- 🔩 Prepare the tool: socket set, hammer, drive puller, torque wrench.
- 🛠️ Clean your work area: Remove dirt and rust from the drive-to-gearbox mount.
- 🛡️ Protect the oil seal: use a mandrel when knocking out the old CV joint so as not to damage the rubber cuff.
- 🧼 Check the status: Inspect the oil seal and replace it if necessary, even if it looks intact.
After removing the shaft, clean it of old grease and install a new CV joint. Make sure the retaining ring is seated correctly in the groove. When installing the drive back into the gearbox, a clear click should be heard confirming fixation. Avoid distortion during installation, as this may damage the internal parts of the gearbox.
☑️ Preparation for replacing the CV joint
What to do if the drive cannot be removed from the gearbox?
If the drive is stuck in the oil seal, do not try to knock it out with a hammer at the end of the shaft. Use a special puller or carefully pry it with a pry bar at the junction with the box, applying force to the metal body of the CV joint, and not to the shaft.
After installing the new unit, be sure to replace the gearbox seal. An old oil seal can leak oil under load, which will lead to a drop in the lubricant level in the gearbox and its overheating. This is a critical step that is often overlooked by inexperienced mechanics.
⚠️ Attention: When installing a new CV joint, make sure that the retaining ring is completely seated in the groove on the shaft. If it does not seat completely, the drive will fly out of the gearbox the first time you try to move off, which can lead to an accident.
The wheel bearing nut must be tightened to a certain torque specified in the service book. Usually for Nissan Almera this value is about 180-200 Nm. Do not skimp on a torque wrench, as an under-tightened nut will lead to rapid wear of the wheel bearing.
Correct tightening of the wheel bearing nut and replacement of the gearbox seal are two factors that determine the reliability of drive repair on a Nissan Almera G15.
Comparison of the characteristics of the original and analogues
To make an informed choice, it is useful to compare the technical characteristics of the original inner left CV joint and its best analogues. The original usually has tighter manufacturing tolerances and uses harder alloys for the raceways, which directly affects the life of the assembly.
| Parameter | Original (Nissan/Renault) | Analogue (GKN/SNR) | Budget option |
|---|---|---|---|
| Average resource (km) | 150 000+ | 100 000 - 120 000 | 40 000 - 60 000 |
| Housing material | Hardened steel | Forged steel | Cast iron or mild steel |
| Lubricant type | Factory specifics | High quality | Standard |
| Price (approx.) | High | Average | Low |
Budget options often don't stand up to harsh driving conditions, especially if you drive on bad roads or skid frequently. The metal in such CV joints can quickly deform, which will lead to play and vibration after just a few thousand kilometers.
When choosing an analogue, pay attention to the packaging and the presence of all necessary components. A good manufacturer always includes a new boot, clamps and lubricant in the kit. The absence of these parts should alert you, as this is a sign of saving on equipment.
Don’t forget that even the most expensive CV joint will not last long if the installation technology was violated or the wrong lubrication was used. Installation quality plays no less a role than the quality of the spare part itself.
⚠️ Attention: Installing a budget CV joint on Nissan Almera G15 with mileage can be justified only if the car is prepared for sale. For constant use, this is uneconomical, since repeated replacement will cost more than immediately buying a high-quality analogue.
Frequent maintenance errors
Many owners and even some craftsmen make typical mistakes when replacing or diagnosing an internal CV joint. One of the most common is an attempt to repair a worn joint by simply adding new lubricant to it. This is useless, since mechanical wear of the raceways has already occurred, and lubricant will not return the metal to its former condition.
Another mistake is using universal lubricants instead of special ones. Lithium grease intended for bearings may not withstand high temperatures and loads inside the CV joint, which will lead to its rapid destruction. Specialized lubricant has a different composition and properties necessary for the operation of constant velocity joints.
They also often forget to check the condition of the gearbox seal. If, when removing the drive, the oil seal is damaged, or if it is old and tarnished, then oil will begin to leak out. This will lead to a decrease in the level of lubricant in the gearbox and, as a result, to its breakdown.
Before starting work, be sure to photograph the location of the levers and mounts on the phone. This will help you quickly and correctly reassemble the suspension without making mistakes in adjusting the angles.
Another critical mistake is not tightening the wheel bearing nut sufficiently. Vibration from a loose nut can destroy the threads on the hub and cause the wheel to fall off while driving. Always use a torque wrench.
⚠️ Attention: Never try to knock out an old CV joint from a hub or transmission by hitting the threaded part of the shaft directly with a hammer. This will ruin the threads and you will not be able to tighten the hub nut, requiring replacement of the entire hub or shaft.
FAQ: Frequently asked questions
How long does the inner CV joint last on a Nissan Almera G15?
The service life of the inner CV joint depends on the quality of the road and driving style. On average, an original unit or a high-quality analogue lasts from 100,000 to 150,000 kilometers. If the boot is damaged, the resource is reduced to 10-20 thousand kilometers.
Is it possible to replace only the inner CV joint without replacing the entire drive?
Yes, technically it is possible. However, it is often more profitable and reliable to replace the drive assembly, especially if the vehicle has a high mileage and there is wear on the outer CV joint or wheel bearing. Replacing only the internal assembly requires more time and effort.
What is the best lubricant for the inner CV joint?
It is best to use special molybdenum disulfide (MoS2)-based lubricants or graphite lubricants designed specifically for constant velocity joints. Conventional lithium grease (Litol-24) is not recommended for these purposes.
How to distinguish the knock of the inner CV joint from the knock of the outer one?
The outer CV joint usually makes a knocking or clicking noise when turning while standing still or in motion. The internal CV joint causes vibration in the body and steering wheel during acceleration, which disappears when the gas is released. Also, the internal one can hum on straight sections of the road.
Do I need to change the gearbox seal when replacing the CV joint?
It is recommended to always change the oil seal. When removing the shaft, the oil seal inevitably receives microtrauma, and the old oil seal may be made of oak. Leaking oil through an old oil seal can cause serious damage to the transmission.
Replacing the inner left CV joint with Nissan Almera G15 is a responsible procedure that requires attention to detail and the use of high-quality components. Don't ignore the first signs of trouble to avoid costly transmission repairs in the future.
Remember that road safety directly depends on the health of your car's chassis. Regular diagnostics and timely replacement of worn-out components is the key to long and comfortable operation of your Nissan Almera.
