Symptoms of internal drive wear on Nissan Almera Classic often confused with other suspension faults. A characteristic knocking sound when starting from a stop, vibration of the steering wheel or body floor during sudden acceleration are sure signs that internal CV joint requires replacement. Ignoring these signals can lead to jamming of the mechanism and complete loss of vehicle control while moving.
The replacement process for a model with a B10 body has its own characteristics that distinguish it from more modern versions. You will have to deal with having to remove the subframe or dismantle the ball joint to free the drive. It is important to understand that the work requires a special puller and significant physical effort, since the fastening of the drive to the gearbox often becomes stuck over time.
Diagnostics and selection of suitable spare parts
Before you go to the store for new parts, you need to accurately confirm the diagnosis. Often owners Nissan Almera Classic they change the entire drive assembly, which is a financially unjustified step. Competent diagnostics allows you to replace only the worn-out grenade, leaving the hub and boot in working order if they are not damaged.
When choosing components, you should pay attention to the manufacturer. The original is always a reliable option, but its cost is high. Alternatives include quality brands such as Febest, SNR or GMB. You should not save on Chinese analogues of unknown brands, as their service life may be less than 10 thousand kilometers, which will lead to repeated repairs.
For diagnosis, you can use a simple method: hang the front wheel and ask an assistant to quickly move off, engaging the gear. If you hear a thud from under the bottom in the engine area, the problem is internal tripoid. Vibration during acceleration on a straight line also indicates play in the joint cage.
⚠️ Attention: If during diagnostics you notice that the boot is torn, but the knocking noise has not yet appeared, do not delay replacement. If dirt and moisture get into the lubricant, the joint will wear out quickly, and repairs will become more expensive due to the need to replace the entire drive.
Necessary tools and preparatory work
Before starting work, make sure you have a complete set of tools. A standard jack and set of wrenches may not be up to the task ahead of you. Pay special attention retaining ring remover and a mount, since without them, removing the drive from the differential will be extremely difficult.
You will definitely need: a 19 and 21 socket for wheel bolts, a ratchet with an extension, a wheel wrench, a pry bar, a ball joint remover, a hammer and penetrating lubricant like WD-40. Also, do not forget to prepare a container for draining transmission oil if you need to unscrew the plug to check the level after installing a new drive.
- 🔧 Puller for drive circlips (special tool)
- 🔧 Torque wrench for tightening hub bolts
- 🔧 Set of sockets and sockets (from 10 to 24 mm)
- 🔧 Prybar and crowbar for pressing the subframe
The vehicle must be securely secured. Use body stands, not just a jack. Working under a machine that relies solely on hydraulics is strictly prohibited. Loosen the wheel bolts with the vehicle on the ground, then jack it up and remove the wheel.
⚠️ Attention: Be sure to check the oil level in the gearbox before starting work. If oil leaks when removing the drive, you should know what volume and type of fluid (usually 75W-90) will be needed to top it up.

Procedure for removing the drive shaft
We begin disassembly by disconnecting the ball joint from the steering knuckle. Unscrew the mounting nut, then use a puller to press the pin out of the cone. If you don't have a puller, you can gently hit the ear of the steering knuckle with a hammer from the side, but do this very carefully so as not to damage the threads or the housing.
After releasing the ball, the steering knuckle is moved to the side. Now you need to remove the drive itself from the gearbox housing. A mount will be required here. Insert it between the engine and the subframe (or between the gearbox and the subframe) and carefully pry off the drive. It should click out when the retaining ring is released from the differential groove.
Sometimes the drive gets stuck tightly. In this case, do not try to pull it out with your hands or hit the shaft with a hammer - you may bend the splines. It is better to use a special puller that screws into the slots and presses on the body. If this is not the case, you can carefully use a pry bar to pry it by the drive housing, and not by the shaft.
☑️ Preparation for dismantling
Replacement of internal tripod and assembly
After removing the drive on a workbench, you need to remove the old boot. Remove the clamps, move the boot to the center and use a hammer and mandrel to knock down the retaining ring. Then carefully knock the tripoid itself off the shaft. If it is tight, use a bearing puller to avoid damaging the shaft splines.
Clean the shaft of old grease and rust. Install a new snap ring into the shaft groove. Put on the new boot and the tripoid itself, applying specialized lubricant to it. Make sure the ring fits tightly into the groove and locks into place. Now put the boot on the CV joint housing and secure it with clamps.
Before installing the drive back into the transmission, check the condition of the seal. If it is worn out or has signs of leakage, it must be replaced, otherwise new oil will leak out. Insert the drive into the differential until it stops until you hear a characteristic click, indicating that the retaining ring is in the groove.
The nuances of replacing the oil seal
If the oil seal leaks, replacing it requires removing the subframe or at least lowering it. This is a labor-intensive procedure that requires draining the oil from the gearbox and removing the drive completely. Often, when replacing a CV joint, the oil seal is not touched if there are no obvious signs of leaks, but if there is severe wear, it is better to replace it immediately to avoid repeated disassembly.
Critical tightening and checking points
Assembly is carried out in reverse order. The hub nut requires special attention. On Nissan Almera Classic it spins with great torque. Use a torque wrench. If the tightening torque is insufficient, the hub will begin to play, which will lead to destruction of the hub bearing. If the torque is exceeded, the threads on the axle shaft can be stripped.
After assembly, be sure to check the operation of the drive. Turn the wheel all the way and try to turn it by hand. There should be no jamming or extraneous sounds. Start the engine, shift into gear and let the car drive. Check for vibration and knocking. Listen to the transmission while driving.
Pay special attention to the boot clamps. They should be tightened tightly, but not pinched. If the boot is overtightened, it may burst from the air pressure inside when heated. If you don’t press it enough, the lubricant will leak out and dirt will get inside. The ideal option is to use specialized clamps with a clamp.
| element | Recommended tightening torque | Tool |
|---|---|---|
| Hub nut | 180-200 Nm | Torque wrench |
| Ball mounting bolts | 60-70 Nm | Ratchet |
| Wheel bolts | 100-110 Nm | Torque wrench |
| Transmission oil drain plug | 30-40 Nm | Ratchet with head |
Proper tightening of the hub nut is the key to long service life of the wheel bearing and driving safety. Neglecting the tightening torque can lead to critical consequences.
Common mistakes and how to avoid them
One of the most common mistakes is trying to knock out the drive with a hammer at the end of the shaft. This leads to deformation of the splines, and the new CV joint simply will not fit onto the shaft, or will play. Always use a mandrel or puller. Also, do not try to pull out the drive by hand if it is jammed - use a pry bar for the lever.
Another mistake is using the wrong lubricant. For tripoids (inner CV joints), a special lubricant with molybdenum disulfide is used, and not the same as for external joints. Improper lubrication quickly destroys tripod needle bearings. Use only the specialized lubricant specified in the instruction manual or on the packaging of the new spare part..
Do not forget to check the condition of the outer CV joint boot. Often, when replacing the internal boot, owners do not notice that the outer boot is torn. If it is not replaced, the entire drive will fail within a couple of weeks. Always inspect both sides of the drive before installation.
⚠️ Attention: If you cannot insert the drive into the gearbox during assembly, do not use excessive force. Most likely, the retaining ring did not fit into the groove or was damaged. Disassemble and check the ring; the drive itself may need to be replaced or the differential repaired.
FAQ: Frequently asked questions from owners
Is it possible to replace only the tripod without changing the entire drive?
Yes, this is possible if the shaft itself is not damaged and there is no play in the splines. However, often when the tripoid is severely worn, the seat on the shaft is also damaged, which makes replacing only the tripoid impractical.
How long does it take to replace an inner CV joint?
An experienced craftsman needs about 2-3 hours per side. For a beginner, it may take 4-5 hours, especially if you have to remove the subframe to access the drive.
Do I need to drain the gearbox when replacing it?
Usually not, unless you change the seal. But it is better to prepare a container, since a small amount of oil may leak out when removing the shaft.
Is it possible to use grease from external CV joints for a tripod?
Strongly not recommended. Tripod grease has a different composition and viscosity necessary for the operation of needle bearings at an angle.
If you are not confident in your abilities, it is better to entrust the work to professionals. Errors when replacing the drive can lead to an accident at speed.
Replacing the inner CV joint with Nissan Almera Classic - a task that can be accomplished for any car owner who is willing to spend time and effort. The main thing is to follow the sequence of actions, use the right tool and not skimp on spare parts. Regularly checking the condition of the boots and lubrication will help avoid premature wear and extend the life of your car.
Remember that road safety depends on the health of the chassis. Do not delay repairs when the first signs of trouble appear. Properly performed repairs guarantee the absence of vibrations and knocks, returning the car to a smooth ride and confident handling.
