Operation Nissan Almera generation G15 under Russian road conditions often reveals vulnerabilities in the suspension and transmission. One of the most critical nodal points is the drive shaft, or more precisely - constant velocity joint (CV joint). This mechanism is responsible for transmitting torque from the gearbox to the wheels, despite constant changes in the angle of inclination during movement.
It is precisely because of the complex geometry of the work and the aggressive environment (dirt, water, reagents) grenade fails more often than many other chassis parts. Ignoring the first signs of failure can lead to complete destruction of the unit while driving, which can lead to loss of control and serious damage to the body or transmission.
Design and features of Almera G15 drives
By car Nissan Almera G15 front-wheel drive modifications are installed, where each drive shaft is equipped with two CV joints: internal and external. The external joint is located directly at the wheel hub and operates at maximum steering angles, while the internal one compensates for changes in shaft length during suspension operation.
Design Feature Nissan Almera is the use of specific anthers and retaining rings, which require precise selection when replacing. Interior CV joint often made in the form of a tripoid (three-pin joint), which ensures a smooth ride, but makes it more sensitive to overheating and lack of lubrication.
The external unit has a classic spherical design. It is important to understand that even minor wear on the treadmill cage or mirror will cause vibration. At the same time, manufacturers often change the drive assembly, but for self-repair, you can only replace the hinge itself, preserving the shaft.
Diagnosis of faults and characteristic symptoms
Understand that CV joint Nissan Almera G15 requires attention, based on a number of clear signs. The most common symptom is a characteristic clicking or crunching sound when the wheels are turned out while driving. If the sound increases during acceleration, the problem is almost certainly in the outer joint.
Vibration during acceleration, which disappears when the gas is released, often indicates wear of the internal tripod. In some cases, the driver may feel a vibration in the steering wheel or the entire front of the car. These symptoms should not be confused with wheel imbalance or wheel bearing problems.
- 🔊 A crunch when turning in place or in motion is a sure sign of wear on the outer grenades.
- 📉 Body vibration when accelerating is a symptom of a faulty internal joint.
- 🕳️ Visible ruptures of the boot and the presence of grease on the wheel are a reason for immediate replacement.
- 📢 Knock when changing gears on the spot (moving forward and backward) - play in the unit.
Regularly checking the condition of the boots can save you significant money. Even a microscopic crack in the rubber allows dirt to penetrate, acting as an abrasive. As a result CV joint wears out within a few hundred kilometers if no measures are taken.
⚠️ Attention: If you hear a loud crunching noise when starting hard with the wheels turned out, stop driving immediately. Destruction of the separator can lead to wheel seizure and loss of controllability.

Selection of spare parts: original or analogues
Spare parts market for Nissan Almera G15 oversaturated with offers, and choose a reliable one CV joint it can be difficult. Original from Nissan (OEM) guarantees compliance with all factory tolerances, but its cost is often 2-3 times higher than the price of a high-quality analogue. At the same time, the resource of the original node can be comparable to the best brands.
Among the proven analogue manufacturers it is worth noting GKN (Spicer), SNR and Kayaba. These companies are often suppliers to conveyors, so their products have a high resource. Cheap Chinese brands (like Febest or Starline) may not last long, especially if they are installed incorrectly.
Pay attention to the kit: it should contain new retaining rings, clamps and, preferably, high-quality lubricant. Savings on anthers unacceptable - use only heat-resistant materials that can withstand high rotation temperatures.
| Manufacturer | Product type | Indicative resource | Recommendation |
|---|---|---|---|
| Nissan (OEM) | External/Internal | 150,000+ km | Ideal for long-term use |
| GKN / Spicer | CV joint kit | 120,000 - 150,000 km | Best price/quality ratio |
| SNR | CV joint kit | 100,000 - 120,000 km | Reliable European option |
| Kayaba | Drive assembly | 100,000 km | Convenient for quick replacement |
You should not buy used units. Even if visually grenade looks intact, the internal condition of the treadmills cannot be determined without flaw detection. The risk of buying a “dead” unit is too great.
A high-quality CV joint should have a tight boot without bubbles or cracks, as well as a set of new circlips in the package.
Step-by-step instructions for replacing the outer CV joint
Replacing external CV joint on Nissan Almera G15 - a task feasible for a home craftsman if he has a lift or pit. The process begins with unscrewing the hub nut, which is tightened with a huge torque. You will need a powerful wrench and a 30 or 32 mm socket (depending on the year of manufacture).
After removing the wheel and disconnecting the suspension arms, it is necessary to press the drive out of the hub. This must be done carefully so as not to damage the axle shaft seal and not to deform the shaft itself. Use a special puller or carefully knock it out through a wooden spacer.
- 🔧 Remove the hub nut and unscrew the bolts securing the ball joint to the steering knuckle.
- 🔨 Carefully knock the drive out of the hub without hitting the threaded part or grenade.
- 🛠️ Unscrew the clamps of the old boot and slide it along the shaft.
- 🔩 Remove the retaining ring and knock out the old CV joint using a hammer and mandrel.
Installing a new node requires the reverse sequence. New CV joint is pressed onto the shaft until it stops until the locking ring snaps into place. This is a critical point: if the ring does not work, the knot will fly off at the first load. Make sure the retaining ring fits into the groove.
☑️ Preparation for replacement
After installing the new CV joint Put the boot on, after putting a special lubricant inside. Secure the clamps: the inner clamp should be tightened tightly, but without overtightening, so as not to crush the rubber. The external clamp must also provide a tight seal.
How to check if the retaining ring is installed correctly?
Pull the drive by hand. If it can be easily removed from the shaft, the ring is not seated. A characteristic click should be heard when putting it on, and the shaft should not wobble in the axial direction.
Reassemble the assembly in reverse order. Don't forget to tighten the hub nut to the required torque (usually about 200 Nm, check your manual). If you don't have a torque wrench, tighten as tightly as possible, but be careful not to strip the threads.
⚠️ Attention: When knocking out an old CV joint, use a copper or wooden spacer. Hitting the joint body directly with a metal hammer can damage the inner race, which will then collapse in the new assembly.
Before installing a new boot, clean the shaft of old grease and dirt. Apply fresh lubricant not only inside the grenade, but also on the shaft itself under the boot to prevent corrosion.
Working with the internal tripoid and oil seal
Internal hinge Nissan Almera G15 often fails due to loss of lubrication or water entering through a damaged boot. Replacing internal tripoid more difficult, since it is located on the gearbox side. Often during this operation it is necessary to change the axle shaft seal.
To remove the inner CV joint, you need to unscrew the fasteners to the differential. Be prepared for some transmission fluid to leak from the transmission. Place the container and check the oil level after repair.
When installing a new unit, make sure that the retaining ring of the new tripod is completely seated in the differential groove. This can be checked by slightly shaking the drive by hand. If there is play, the ring is not seated and the assembly needs to be rearranged.
It is important to check the condition of the seal. If it has traces of oil or cracks, replacement is required. Oil leakage through the oil seal will lead to a decrease in the level of lubrication in the gearbox and failure of the gearbox.
⚠️ Attention: Never use a tool to remove the inner CV joint from the transmission unless you are confident in your abilities. You may damage the differential housing or seal. Use a special puller.
Replacing the inner CV joint requires attention to the oil level in the gearbox and the condition of the oil seal in order to avoid leaks.
Typical repair mistakes and their consequences
Many owners Nissan Almera G15 make the mistake of trying to prolong the life of an old bastard. Sealing cracks with tape or using sealants does not work. Dirt trapped inside acts like sandpaper. CV joint wears out over several tens of kilometers.
Another common mistake is not tightening the clamps correctly. A clamp that is too weak will allow the lubricant to leak out, while a clamp that is too strong can pinch the rubber, causing it to rupture when heated. Use only standard clamps or high-quality stainless steel clamps.
Ignoring replacement of retaining rings is a sure path to rapid failure. Old rings are worn out and may not provide a secure fit. Always use the new kit included with your CV joint.
- ❌ Using cheap clamps that break when tightened.
- ❌ Saving on lubrication and using universal lubricants instead of specialized ones.
- ❌ Attempting to install the CV joint without checking the retaining ring.
- ❌ Ignoring the replacement of the oil seal when removing the internal drive.
Properly performed repairs will last a long time. If you doubt your skills, it is better to entrust the work to professionals, since the cost of a mistake can be many times higher than the cost of the service center’s services.
FAQ: Frequently asked questions from owners
How long does a CV joint last on a Nissan Almera G15?
The resource depends on the quality of roads and driving style. On average, assuming a whole anther, CV joint runs from 100,000 to 150,000 km. If dirt gets in, the service life is reduced to 5-10 thousand km.
Is it possible to drive with a torn CV boot?
Technically possible, but highly not recommended. Maximum 50-100 km to the nearest service. Dirt will quickly destroy the internal surfaces, and replacement will be more expensive due to the need to buy a new drive entirely.
How to distinguish the left CV joint from the right one?
On Nissan Almera G15 Drives may differ in shaft length and retaining ring type. Always check the part number on the packaging with the number on the old unit. Left and right drives are often not interchangeable.
What kind of lubricant is needed for a CV joint?
Use special lubricants based on molybdenum disulfide (MoS2) designated “for CV joints.” Universal lubricants like Litol-24 are not suitable for high loads and temperatures in joints.
Why does the CV joint only crunch when turning?
This is a classic sign of wear on the outer joint. When turning, the joint operates at its maximum angle, and the worn raceways begin to “jump”, creating a characteristic sound.
