Cars Nissan Primera P12 deservedly respected among car enthusiasts due to their balanced suspension and reliable design. However, like any mechanism, the transmission of this sedan or hatchback is subject to wear, especially in difficult road conditions. Some of the most critical nodes here are constant velocity joints, which transmit torque from the gearbox to the wheels.
If you notice a characteristic crunch when turning or vibration when accelerating, the problem lies precisely in this unit. Ignoring the symptoms can lead to jamming of the mechanism and costly repairs to the entire axle shaft. In this article we will look in detail at how to correctly diagnose, select and replace CV joint for Nissan Primera P12to get your car running smoothly and quietly again.
Design and principle of operation of the P12 transmission
The design of the front-wheel drive transmission is based on Nissan Primera lies a complex system of shafts and hinges. External CV joint is responsible for transmitting torque when turning the wheels, allowing them to change the angle relative to the drive axis. Inner CV joint compensates for changes in the length of the axle shaft during suspension operation, compressing and decompressing on uneven roads.
Particular attention should be paid to the fact that the P12 model uses different types of joints depending on the year of manufacture and engine power. For versions with 1.8 and 2.0 liters, the parameters may differ, so when purchasing a spare part you need to check spare parts articles. An incorrectly selected element will quickly fail, even if it seems visually identical.
The hinge design includes a cage, a separator and balls that roll along the grooves. CV boot plays a decisive role in protecting this mechanism from dirt and moisture. If the rubber breaks, abrasive particles immediately get inside, turning the lubricant into an abrasive paste.
The main signs of a hinge failure
Understand that drive shaft requires replacement, not always difficult if you listen to the car. The very first and surest sign is a clicking or crunching sound that occurs when the wheels are turned out. This usually indicates wear and tear. external CV joint, since it is he who experiences the maximum loads when turning.
The internal joint may behave differently - often it is vibration transmitted to the body during acceleration, especially at high speeds. Sometimes the vibration is felt even at idle when the car is moving. It is also worth paying attention to the condition protective cover: If it is torn, replacement is inevitable.
- 🔊 A characteristic crunch when turning the steering wheel all the way and starting from a standstill.
- 🌊 An audible metallic grinding sound when driving in a straight line with a load.
- 🛠️ Visual traces of grease around the wheel or suspension.
- 🚗 Vibration of the steering wheel and car floor when accelerating.
Sometimes the problem may be hidden not in the joint itself, but in the wheel bearing, which makes a similar noise. Therefore, before purchasing expensive parts, it is important to conduct a thorough diagnosis. Backlash in the drive You can check by shaking the wheel with your hands, but it is better to entrust this to professionals on a lift.
⚠️ Attention: Do not try to drive a car with a completely destroyed CV joint. Failure of the joint while driving can lead to wheel jamming and complete loss of control, which can lead to a serious accident.
Choosing an original or a high-quality analogue
Spare parts market for Nissan Primera P12 offers a huge selection of options, from dealer originals to budget Chinese analogues. Original CV joint Nissan, of course, provides maximum service life and precision, but its price is often overpriced. For many owners, this is an unjustified expense, especially if the car is no longer new.
There are trusted manufacturers who make hinges no worse, and sometimes better, than factory ones. Brands like GKN, Loebro or NTN are often direct suppliers to the conveyor. Their products are distinguished by high-quality steel and precise groove geometry, which guarantees a long service life.
When choosing an analogue, be sure to check the package contents. A good kit should contain: the hinge itself, a new boot, a retaining ring, clamps and a tube of specialized lubricant. Cheap options are often sold without boots or with low-quality rubber that will crack within a month.

Tools and preparation for repairs
Replacement CV joint for Nissan Primera - a task of medium complexity that can be performed in a garage environment with the right set of tools. You will definitely need a jack, a wheel wrench, and a set of sockets and wrenches. Pay special attention to the wrench for unscrewing the hub nut, as it is often tightened with enormous force.
To remove the drive, you will need a ball joint and hub puller. If you do not have a professional puller, you can use a mounting spatula, but you must act extremely carefully so as not to damage the suspension parts. Also don't forget to prepare copper grease for threaded connections that may stick.
- 🔧 Set of socket heads from 12 to 32 mm and extensions.
- 🛠️ Ball joint and wheel nut remover.
- 🔨 Hammer and chisel (or punch) for knocking out the CV joint.
- 🧼 Brake cleaner and rags to remove old grease.
☑️ Preparation for replacing the CV joint
Before starting work, be sure to place the vehicle on a level surface and apply the handbrake. If you are changing only one side, it is recommended to block the wheels on the opposite side. This will prevent the transmission from spinning and make the removal process safer.
Step-by-step instructions for replacing the outer CV joint
The first step is to remove the wheel and unscrew the hub nut. On Nissan Primera P12 this nut has left or right hand threads depending on the side, but usually the right side has a standard right hand thread. Use a wrench with enough leverage to remove the nut.
Next you need to disconnect the lower ball joint. Unscrew the fastening bolt and knock out the ball pin using a puller or pry bar. After this, you can move the steering knuckle to the side and gain access to the inner end of the axle shaft. Remove the drive completely not necessary, just remove it from the hub.
Now you need to knock out the old CV joint from the axle shaft. Use a soft metal drift to avoid damaging the gear teeth or the shaft itself. The blows must be directed strictly along the axis of the shaft. After removing the old assembly, clean the axle shaft splines of old grease and corrosion.
What to do if the CV joint cannot be removed?
If the hinge is stuck, do not hit it directly with a hammer. Use a special puller or carefully heat the seat with a blowtorch, being careful not to overheat the metal of the axle shaft.
Place the new boot on the shaft, then put the new one on CV joint all the way. Hammer it in carefully, alternating strikes on the clip. Install the retaining ring that secures the joint to the shaft. Make sure it is completely seated in the groove, otherwise the assembly will fall apart when moving.
Fill the internal cavity of the hinge and boot with special lubricant. Do not skimp on the composition, but do not overdo it, so as not to tear the boot when expanding. Place the boot on the hub and secure it with clamps. Be careful not to damage the rubber when tightening.
Important nuances of assembly and configuration
After installing the new CV joint, all fasteners must be properly tightened. The hub nut must be tightened to a certain torque, which is usually around 180-200 Nm. If you don't have a torque wrench, tighten it all the way, but be careful not to strip the threads.
Don't forget to check the status internal CV joint. When removing the axle shaft, it also experiences load. If you hear a crunching sound when driving in a straight line, the problem may be in the internal assembly. In this case, it is recommended to replace both joints as a set.
⚠️ Attention: Before starting movement, be sure to check the integrity of the anthers. If the clamps are twisted or the rubber is damaged, dirt will get into the joint and the new CV joint will quickly fail.
Reassemble the suspension in the reverse order: install the steering knuckle on the ball joint, tighten the bolt, insert the axle shaft into the gearbox. Make sure the drive is fully engaged with the differential. Sometimes it takes several hits with a hammer on the end of the axle shaft (through a piece of wood) to get it to sit in place.
Proper tightening of the wheel nut is the key to ensuring that the wheel bearing does not overheat and fail prematurely.
