Owners of a compact crossover Nissan Juke are often faced with the need to check and replace transmission elements, especially with significant mileage. One of the most critical parts in the wheel drive system is the constant velocity joint, or as it is more commonly called. CV joint. This part transmits torque from the gearbox to the wheels, allowing them to turn and rotate at different angles at the same time.
Breakdown grenades on Nissan Juke may result in complete loss of control of the vehicle or the wheel seizing while in motion, which poses a direct safety hazard. That is why it is important to be able to recognize the first signs of a malfunction in time and know how to correctly select and replace this unit. In this article we will analyze in detail all aspects of CV joint maintenance on this model.
Design and role of the CV joint in the Nissan Juke transmission
By car Nissan Jukeequipped with front-wheel drive or all-wheel drive, a complex drive system is used, consisting of two main joints on each wheel: an internal and an external one. Inner CV joint is responsible for transmitting torque and compensating for changes in the length of the axle shaft during suspension operation, while external CV joint ensures transmission of rotation to the wheel hub when turning it.
Design Feature Nissan Juke is that both types of hinges operate under extreme conditions: constant shock loads, dirt, water and temperature changes. CV boot plays a key role in protecting the lubricant and bearing bodies from abrasive particles. If the integrity of the rubber boot is compromised, sand and moisture quickly lead to wear of the separator and grenades.
It is important to understand that drive shaft - this is a single unit where the internal and external hinges are inextricably linked. During repairs, a dilemma often arises: to replace only the grenade itself or the entire shaft assembly. For owners Nissan Juke with a mileage of more than 100 thousand kilometers, it is often more profitable and reliable to install a restored or new drive assembly to eliminate imbalance.
The main signs of a hinge failure
The problem can be identified before the part is completely destroyed. The surest sign is characteristic crunch when turning steering wheel If the sound is heard only when moving to the left, it means that the right CV joint is faulty, and vice versa. This sound is caused by wear in the raceways when the rolling elements begin to get stuck and slip.
In addition to sound, problems may be indicated by:
- 🔊 Body vibration during acceleration, which disappears when the gas is released.
- 🔊 An audible knocking or metallic clanging sound when starting from a standstill.
- 🔊 Jerks when changing gears or sharply pressing the gas pedal.
A visual inspection can also tell a lot. Inspect the area under the car: if you see marks CV joint lubricants on the inner walls of the wheel or on the suspension elements, this is a sure signal of a torn boot. Even a small crack in the rubber eventually turns into a gap through which all the lubricant flies out.
⚠️ Attention: If you hear a strong crunching noise while driving, do not try to travel long distances. This can lead to complete wheel separation or transmission jamming at the most inopportune moment.

Diagnostics and preparation for replacement
Before starting work, it is necessary to accurately localize the fault. Raise the car on a lift or jack and ask an assistant to turn the steering wheel as far as it will go while giving the gas. If the sound intensifies, the diagnosis is confirmed. Also check the play in the hinge itself: grab the shaft with both hands and try to turn it counterclockwise and back.
To perform the work you will need a standard set of tools, as well as specific devices. Pay special attention to the tool for removing the retaining ring from the drive shaft, as it often sticks or becomes deformed. Do not try to knock out the shaft with a hammer without support as this may damage the differential.
Prepare the workplace: be sure to put chocks under the wheels and check the reliability of the jack. Grease for CV joints must be specialized (usually with molybdenum disulfide); in no case use lithol or grease, as they cannot withstand high temperatures and loads.
☑️ Preparation for replacing the CV joint
Step-by-step replacement instructions
The process of replacing an external CV joint with Nissan Juke requires accuracy. Start by removing the wheel and unscrewing the central hub nut (it is large and torqued). Loosen the bolts securing the ball joint to the steering knuckle to make room for removing the drive.
The next step is to remove the drive shaft from the differential. To do this, you need to carefully pry off the shaft with a mounting tool without damaging the seal. Once the shaft comes out of the box, it must be completely removed from the car. Now you can unscrew the old CV joint and install the new one using a mandrel or the old drive shaft.
Installing a new boot requires care. Put it on the shaft, fill the inside special lubricant, then slide the joint onto the shaft until the lock ring clicks. Make sure that the ring is seated in the groove, otherwise the shaft will fly out during the first ride.
Frequent mistakes when replacing CV joints
1. The lock ring is not tightened enough (the drive flies out). 2. Damage to the boot during installation (quick failure). 3. Using the wrong lubricant (destruction of the grenade). 4. Re-tightening the clamps (cutting the rubber).
⚠️ Attention: When reassembling, be sure to replace the hub nut with a new one. An old nut has a deformed thread and will not provide the required tightening force, which will lead to destruction of the wheel bearing.
Before final tightening of the wheel nut, place the vehicle on the wheels and lower it slightly to distribute the load on the suspension. This will ensure that the nut is properly tightened under load as specified by the manufacturer.
Features of servicing the internal CV joint
Inner CV joint on Nissan Juke often changes along with the external one, since their resource is approximately the same. However, if the problem is only in the inner joint, the diagnosis is more difficult. It usually makes a dull knock when starting suddenly or when the engine brakes when the direction of the load changes.
Replacing the inner CV joint requires removing the entire drive shaft and disassembling it. Prepare a container to collect the oil and check the level after repair. Also inspect the transmission seal for wear.
When assembling the inner joint, pay special attention to centering. The shaft should enter the differential smoothly, without shock. If you feel resistance, do not use force - check the position of the locking ring. An incorrectly installed ring can damage the differential or seal.
Repair costs and prevention
The total cost of replacing a CV joint is Nissan Juke consists of the price of spare parts and labor. On average, replacing one external hinge at a service center will cost 3,000-4,500 rubles. If you are replacing both CV joints at once, the cost of the job may be lower due to saving time on disassembly.
To extend the life of new parts, follow simple rules:
- ✅ Inspect the dust boots regularly during every maintenance or wash.
- ✅ Avoid sudden starts with slipping, especially on uneven roads.
- ✅ Don't ignore the first signs of crunching - early replacement of the boot costs a penny.
Remember that timely replacement of a torn boot costs 10 times less than buying a new CV joint. Regularly inspecting your suspension can save you significant money and hassle. Do not delay a visit to the specialist if suspicious sounds appear.
Why can't you drive with a torn boot?
Moisture and sand enter the lubricant, turning it into an abrasive paste. This leads to rapid wear of the raceways, the appearance of backlash and, ultimately, to the destruction of the hinge within 500-1000 km.
Frequently asked questions (FAQ)
Is it possible to replace only the CV joint and not the entire shaft?
Yes, technically it is possible. However, on Nissan Juke It often happens that during dismantling the old shaft is deformed or the oil seal is damaged. Many craftsmen recommend replacing the shaft assembly, as it is more reliable and faster.
How much lubrication does a CV joint need?
Usually a package of lubricant weighing about 100-120 grams is included. This is enough to fill the internal volume of the hinge. Excess lubricant is not needed, since when heated it expands and can rupture the boot.
Is it possible to drive if you hear a crunching sound?
Short term - yes, but with great caution. If the CV joint completely fails, you will be left without control while driving. It is better to immediately contact the service for diagnosis and replacement.
Do I need to change the oil seal when replacing the CV joint?
Recommended. If the seal is old, it may be damaged when the shaft is removed. Leaking oil from the gearbox will lead to a drop in the lubricant level and damage to the gearbox.
How to check the CV joint without disassembling?
Try turning the steering wheel all the way and driving off quickly. A crunch will indicate the outer joint. To check the internal one, you need to sharply brake the engine or pull away on a straight line, listening to a knock under the bottom.
