Replacing the internal CV joint Nissan Almera N16: Complete repair guide

Symptoms of a drive malfunction Nissan Almera N16 is often confused with suspension problems, but the characteristic crunch when turning and vibration during acceleration clearly indicate wear of the constant velocity joints. The inner CV joint is responsible for transmitting torque from the gearbox to the outer joint, compensating for the longitudinal movements of the axle shaft during suspension operation.

Ignoring signs of wear leads to critical consequences: destruction of the joint inside the housing can lock the wheel or damage the transmission seal, causing an oil leak. Regular diagnostics and timely replacement allow you to avoid expensive transmission repairs and ensure traffic safety.

The replacement process requires a certain set of tools and adherence to technological nuances characteristic of front-wheel drive cars of the B-class platform. You have to remove the axle shaft, remove the old hinge and install a new one without compromising the integrity of the boot and the tightness of the assembly.

Diagnostics and signs of malfunction of the internal CV joint

The main indicator of problems with the internal tripod (or ball joint, depending on the configuration) is vibration that occurs during sudden acceleration. Unlike the external CV joint, which crunches when turning, the internal one often manifests itself with a hum or beating of the steering wheel at high speeds.

Visual inspection allows you to identify ruptures in the boot. If the rubber boot is torn, dirt and moisture get inside the joint, which leads to rapid wear of the needle bearings or balls. Lack of lubrication even for a short time can render the part unsuitable for further use.

Another sign is axle shaft play. If you shake the shaft by hand without disconnecting it from the box and feel noticeable movement, this indicates wear in the seats. Often the problem is accompanied by a characteristic knocking sound when starting off.

• 🔍 Body vibration during acceleration, especially in second or third gear.
• 🔊 Extraneous knocking noise when starting from a standstill or changing gears.
• 🛢 Oil leaks from the axle shaft seal due to damage to the boot.

Selection of necessary spare parts and tools

For a quality repair, you will need a new inner joint, boot kit, snap ring and special CV joint lubricant. When purchasing a part, pay attention to the manufacturer: original spare parts Nissan have a high resource, but their cost is significantly higher than their analogues.

It is important to choose exactly the modification that suits your engine (1.4, 1.5 or 1.6 liters). The number of splines on the shaft and the diameter of the mounting hole may vary. Incorrectly selected part will not allow installation of the axle shaft or will lead to its rapid destruction.

The tool you will need is a powerful wrench, a set of sockets (including wrenches 17, 19, 24), a pry bar, a circlip remover and a mandrel for pressing in the CV joint. You also cannot do without a hammer and a vice to remove the old part from the shaft.

• 🛠 Powerful wrench and extension for unscrewing the hub nut (tightening torque up to 180 Nm).
• 🔨 Retaining ring remover and mounting spatula for pressing out the axle shaft.
• 🧰 Special lubricant for tripoids (usually black, with molybdenum disulfide).

⚠️ Attention: Try not to buy components from unknown brands without quality certificates. Cheap analogues often have low metal hardness, which leads to the destruction of the hinge after just a few thousand kilometers.

Preparing the vehicle and removing the axle shaft

Before starting work, it is necessary to ensure access to the suspension. Raise the front of the car on jacks, place it on secure stands and remove the wheel. Be sure to loosen the hub nut on the ground while the car is on its wheels, as it is tightened with a lot of force.

To remove the axle shaft from the hub, you will need to unscrew the fastening nut, remove the lower arm or ball joint (depending on the design) and knock the hub off the shaft. Do this carefully so as not to damage the threads and hub bearing.

After this, disconnect the axle shaft from the gearbox. Use a pry bar by prying the shaft near the oil seal. Be extremely careful: sudden movement may damage the seal, resulting in the need to replace it. Degree of oil seal wear needs to be assessed immediately.

• 🚗 Raise the car and secure it on “goats” or stands.
• 🔩 Unscrew the hub nut and remove the wheel to access the suspension.
• 🔧 Disconnect the lower part of the strut to press the axle shaft out of the hub.

Replacing the internal joint on the shaft

With the axle shaft removed, it is necessary to clamp the shaft in a vice, but not too tightly so as not to deform it. Using a chisel or special puller, remove the retaining ring holding the CV joint to the shaft. After this, knock down the old hinge with a sharp blow of a hammer through a wooden spacer.

Clean the shaft of old grease and rust. Make sure the splines are free of burrs. Place the new boot on the shaft, then lubricate the inside of the joint and the shaft with new grease. Lubricant quantity should be sufficient, but without fanaticism, so that the boot is not deformed by excess pressure.

Press the new CV joint onto the shaft. Use a mandrel or piece of pipe of suitable diameter, resting on the inner race of the hinge. The blows must be uniform so that the part sits evenly. Finally, install the new snap ring and make sure it is securely seated in the groove.

How to check the quality of pressing?

After installation, try to rotate the CV joint relative to the shaft. If there is play or it does not rotate smoothly, it means the part is installed crookedly or defective.

Secure the boot to the shaft with clamps. First tighten the small clamp on the shaft side, then get air into the boot (you can use a compressor or just blow into it) to align it, and tighten the large clamp. This will prevent the formation of a vacuum during operation.

Installing the axle shaft back onto the car

Before installation, check the condition of the gearbox seal. If it leaks or has visible damage, it must be replaced. Insert the new axle shaft into the transmission until the retaining ring clicks into place. Make sure that the shaft is fully inserted and does not fall out when rocking.

Then align the shaft splines with the hub and drive the axle shaft until it stops. Do not use a hammer directly on the end of the shaft to avoid damaging the splines. Hang the strut back up and tighten the ball joint or arm nut.

Install the wheel and lower the car. Tighten the hub nut with a torque wrench to the recommended torque. If you don't have one, tighten it as tight as possible without stripping the threads. Control tightening after 500 km is required.

Parameter	Meaning	Comment
Hub nut tightening torque	160-180 Nm	Depends on year of manufacture
Wheel bolt tightening torque	100-110 Nm	Standard for N16
Lubricant quantity	80-120 g	Internal hinge
Lubricant type	MoS2 (Molybdenum disulfide)	For tripoid joints

Typical repair mistakes

One of the most common mistakes is using universal lithium grease instead of specialized grease for CV joints. Conventional lubricant is quickly washed out and does not withstand high temperatures and loads, which leads to jamming of the hinge.

Another problem is improper installation of the boot. If you do not release the air from the boot before tightening the clamps, when the suspension is operating, the boot will inflate like a ball and tear. It is also unacceptable to leave gaps in the places where the clamps are attached.

Sometimes craftsmen forget to replace the retaining ring. An old ring may be stretched and will not provide a secure fit, which could cause the axle shaft to jump out of the transmission while driving. This is extremely dangerous.

• 🚫 Using Litol-24 type lubricant instead of a specialized one.
• 🚫 Ignoring the replacement of the axle circlip.
• 🚫 Damage to shaft splines when struck with a hammer.

⚠️ Attention: Never use a gas wrench to clamp the shaft in a vice when removing the CV joint, as this can deform the shaft and upset the balance.

What to do if the oil seal is leaking?

You can replace the oil seal without removing the gearbox. You will need to remove the axle shaft, knock out the old oil seal and press in a new one using a mandrel of a suitable diameter.

Conclusion and final recommendations

Replacing the inner CV joint with Nissan Almera N16 - a task of medium complexity that can be performed in a garage with basic tools. The main requirement is care when working with transmission parts and the use of high-quality consumables.

Once repairs are complete, test drive. Pay attention to the absence of vibrations during acceleration and extraneous noise when changing gears. If everything is in order, after a week it is recommended to check the tightness of the hub nut and the condition of the boot.

Regular inspection of the drive, especially after driving off-road or in deep snow, will help identify minor damage to the boot before it leads to serious damage. Timely replacement of lubricant and boot increases the life of the CV joint by 3-4 times.

How to distinguish an internal CV joint from an external one on a Nissan Almera N16?

The inner joint is usually located closer to the gearbox and is a tripod (three-ball) design with needle bearings, although on some early models it may be a ball joint. The outer CV joint is located at the wheel and has a classic ball design (Rzeppa). The inner joint is shorter and often has a more compact boot.

Is it possible to replace only the inner CV joint boot?

Technically this is possible if the hinge itself does not have a groove. However, if the boot was torn a long time ago, dirt had already gotten inside, and the bearings could wear out. In most cases, it is recommended to replace the hinge assembly, since the cost of repairing an old assembly is often comparable to purchasing a new one.

Do I need to replace both CV joints at once?

No, it is not necessary to change both CV joints at once if the second one is in perfect condition. However, many masters recommend doing this, since they have approximately the same resource, and after a short time the node may need to be parsed again.

What is the best lubricant for the inner CV joint?

For internal tripod joints, a molybdenum disulfide (MoS2) lubricant, often black in color, is ideal. It has high adhesion and can withstand high sliding loads. Do not use lubricant for external CV joints (gray or silver), as it may not be suitable in viscosity.
