Sedan owners Nissan Almera Classic often encounter the problem of wear of chassis elements, especially at high mileage. The critical component of the transmission is the drive shaft, or more precisely, its articulated joints. Interior CV joint (constant velocity joint) is responsible for transmitting torque from the gearbox to the wheel, while compensating for the vertical movements of the suspension.
Ignoring the symptoms of a malfunction can lead to jamming of the mechanism and a complete stop of the car in motion. For model Nissan Almera Classic Characterized by specific breakdowns, which are often confused with other suspension faults. Understanding the principles of operation, the ability to diagnose a problem and the correct selection of spare parts is the key to long-term and safe operation of your car.
Inner joint design and function
Interior CV joint in drive design Nissan Almera Classic plays the role of a compensator. Unlike the outer hinge, which operates at large rotation angles, the inner joint is more subject to axial loads. It must move smoothly along the axis of the shaft during compression and rebound of the shock absorber, without losing its ability to transmit torque.
Structurally, this unit is a housing with a separator and balls that roll along special grooves. Interior drive shaft equipped with a “tripod” (three-needle joint) or a ball mechanism, depending on the modification of the gearbox and the year of manufacture. It is this mechanism that ensures reliable transmission of force under dynamic loads.
The key element that protects the mechanism from dirt and moisture is the boot. Rubber cover must be elastic and airtight. Any damage to the boot leads to leaching of the lubricant and the entry of abrasive particles, which causes rapid expulsion of the raceways and balls.
⚠️ Attention: Do not try to “reanimate” the internal CV joint through washing and replacing the lubricant, if a clear crunching sound is heard. This is only a temporary measure and may result in housing collapse and damage to the transmission. The unit should be replaced only at the first sign of knocking or play.
Main symptoms of malfunction and diagnostics
The problem can be determined by the characteristic sounds and sensations when driving. The most common symptom of a worn inner joint is a clunking or metallic grinding noise heard when starting hard from a stop or shifting gears under load. If the sound appears only during acceleration, and disappears when you release the gas, this is a sure sign of a breakdown.
It is important to distinguish the knock of internal CV joint from problems with the suspension or external hinge. The outer joint usually crunches when turning, while the inner one makes itself felt precisely when the torque changes on a straight path. You may also experience vibration in the steering wheel or the entire body at high speeds.
- 🔊 A dull metallic knock when starting abruptly from a standstill.
- 📉 Drive vibration during acceleration, which occurs after releasing the gas.
- 💥 Jerks when changing gears, especially from first to second.
- 🔧 Axial play of the shaft during manual check (with the wheel hanging).
For an accurate diagnosis, you need to lift the car on a lift or use a jack. By rotating the wheel with your hands and at the same time feeling the joint body, you can feel jamming or play. Also inspect the boot for cracks or tears.
- Once a year
- Only when there is noise
- Never checked
- Every maintenance
Selection of quality spare parts and analogues
Spare parts market for Nissan Almera Classic oversaturated with offers, and the choice of quality internal CV joint can be a challenging task. Original part from Nissan has a high resource, but is quite expensive. It is often sold complete with a drive shaft, which increases the cost of repairs.
There are many proven analogues from manufacturers specializing in drives. Brands like GKN (Spicer), Kartex or Febi have proven themselves to be reliable replacements. It is important to pay attention to the markings and country of origin, avoiding fakes that can fail after a couple of thousand kilometers.
When choosing, pay attention to the equipment. In some cases, it is more profitable to buy a separate housing, and in others, a complete set with a shaft. Make sure that the kit includes a new boot and clamps, as old elements are often damaged during dismantling.

Before purchasing, be sure to compare the part number according to the VIN code of your car, since for different years of manufacture Nissan Almera Classic Different types of drive could be installed.
Preparation for replacement and necessary tools
Internal replacement process CV joint requires specialized tools and certain skills. You will need a jack, stands, a set of wrenches and sockets, and a circlip puller. It is better to carry out work on an inspection pit or a lift for easy access to the gearbox.
Before starting work, it is necessary to loosen the wheel bolts and the hub nut. This is done before the car is lifted to prevent the wheel from spinning. Make sure the vehicle is securely supported on jack stands as work will be done underneath the vehicle.
- 🔧 Set of sockets (17, 19, 21, 24 mm) and ratchet.
- 🔨 Hammer and assembly shovel for dismantling.
- ⚙️ Retaining ring remover (for removing the retainer from the gearbox shaft).
- 🧴 Grease for CV joints and sealant.
Don't forget to prepare a container to drain the oil from the gearbox if you have to remove the drive completely. In some cases, it is enough just to loosen the fastening to remove the shaft, but there is always a risk of oil leakage. You will also need a new boot and clamps, even if the old one looks intact.
☑️ Preparation for replacement
Step-by-step replacement instructions
Start by removing the wheel and disconnecting the suspension arm from the steering knuckle. This will release the outer joint and remove the entire drive shaft from the hub. Be careful not to damage the brake hose and shock absorber boot when retracting the lever.
Next, you need to remove the drive from the gearbox. To do this, carefully use a pry bar to pry the housing of the internal CV joint and push it out. Be prepared for some transmission oil to leak. Carefully inspect the seat in the box for damage to the seal.
On the removed shaft, it is necessary to dismantle the old hinge. Use a circlip puller to remove the retainer and carefully knock out the old assembly. Clean the shaft of old grease and rust. Install new CV joint, driving it carefully through the mandrel so as not to damage the separator.
Features of installing the retaining ring
The retaining ring should click when installed. Check the reliability of the fixation by trying to move the CV joint along the shaft with your hands. If there is play, the ring is installed incorrectly or damaged.
After installing the new mechanism, put on the boot, having previously put a special lubricant in it. Tighten the clamps in two stages: first onto the body, then onto the shaft. Make sure that there is no air left in the boot so that it does not swell when heated.
Proper installation of the retaining ring is critical: if it does not fit into the groove, the drive will fly out of the gearbox during the first acceleration.
⚠️ Warning: Never use a hammer directly on the hinge body or cage. Impacts must be applied through a wooden spacer or through a mandrel of suitable diameter to avoid deformation of the parts.
Checking the quality of work and nuances of operation
After assembly, you need to check that the installation is correct. Install the wheel, lower the vehicle and tighten the wheel nut to the recommended torque. Start the engine and check the transmission at idle and while driving.
Carry out a test drive, paying attention to the absence of extraneous noise. Make sure that there are no vibrations during acceleration and that the steering wheel does not jerk. If everything is in order, after 500-1000 kilometers it is recommended to check the tightness of the boot clamps and the oil level in the gearbox.
Regular inspection of the condition of the anthers is the best prevention. If you notice traces of grease on the wheels or under the vehicle, replace the boot immediately. Timely replacement of a protective cover costs pennies compared to replacing the entire drive or gearbox.
- 🚗 Carry out test acceleration and braking in different modes.
- 🔍 Visually check for oil leaks from the gearbox after replacement.
- 📅 Plan to check the clamps again after 1000 km.
⚠️ Attention: If knocking remains after replacement, check the condition of the engine and gearbox mounts. Often, vibration from worn bearings is transmitted to the drive and imitates the knock of a CV joint.
Frequently asked questions (FAQ)
Is it possible to replace only the inner CV joint and not the entire drive assembly?
Yes, on Nissan Almera Classic The internal part of the drive can be replaced separately. This will require removing the drive from the transmission and removing the old joint from the shaft. However, the cost of labor and the risk of damaging the shaft during removal may make replacing the entire drive assembly more cost-effective.
What is the best lubricant to fill a new CV joint?
Use a special constant velocity joint grease (such as MoS2 or lithium grease with additives). Do not use graphite grease or regular motor oil, as they cannot withstand high loads and temperatures in the friction unit.
Why does a new CV joint knock immediately after installation?
This may be due to incorrect installation of the retaining ring, which does not click into the groove, or damage to the seat in the gearbox. It is also possible that you purchased a low-quality spare part that is defective. Check the fit and replace the part if necessary.
How long does it take to replace an inner CV joint?
For an experienced technician, replacing the internal hinge takes about 1.5–2 hours. A beginner without experience or special tools may need 3-4 hours, especially if he has to deal with stuck bolts and difficulties in dismantling the drive.
Do I need to change the gearbox seal when replacing the CV joint?
It is recommended to replace the seal immediately, especially if you notice oil leakage or if the seal was damaged when the drive was removed. This will prevent a repeat service visit and loss of transmission oil.
