Often crossover owners Nissan Qashqai The first generation encounters a characteristic vibration during acceleration, which disappears when the gas is released. This problem often indicates wear on the inner drive joint (CV joint). Unlike the outer one, which gives itself away with a crunching sound when cornering, the inner element begins to play and transfer shocks to the gearbox and the car body. Ignoring these signs can lead to axle shaft destruction and costly transmission repairs.
The process of replacing the right inner CV joint on the platform Renault-Nissan has its own technical features related to the design of the suspension and the arrangement of elements. The right side often experiences heavy loads due to the location of the exhaust system and the heat dissipation features. Correct diagnostics and the use of high-quality tools allow you to do the work yourself, saving a significant amount on car service costs, but only subject to strict adherence to the flow charts.
В этой статье мы разберем все этапы работ: от снятия полуоси до установки нового шарнира и проверки герметичности пыльника. We will pay special attention to the nuances of dismantling the retaining ring and pressing in a new part, since this is where mistakes are most often made, leading to repeated failure of the unit.
Diagnostics and signs of malfunction of the internal CV joint
Determine the malfunction of the internal drive joint Nissan Qashqai J10 possible by a number of specific symptoms, which are often confused with suspension problems or wheel camber. Главным индикатором является ощутимая вибрация, передаваемая на кузов и руль при разгоне с места или при наборе скорости в диапазоне от 40 до 80 км/ч. This vibration is rhythmic in nature and increases as engine speed increases, but disappears completely if the accelerator pedal is released.
The second important sign is the appearance of a knocking or metallic clanging sound when starting abruptly or changing gears. The sound occurs when torque is transferred from the gearbox to the wheels. If you hear such sounds while in the car, or feel a beating through the floor of the car, you must immediately inspect the drive. Owners often mistakenly believe that the problem is in ball joints or silent blocks, but if there is vibration during acceleration, the diagnosis is almost always clear.
A visual inspection can also provide clues, although the inner CV joint is hidden under the boot. Pay attention to the presence of transmission oil leaks from under the boot and traces of grease on the inner sides of the wheels. If the boot is torn, dirt and moisture have already entered the assembly, which inevitably leads to accelerated wear of the splines and balls. In this case, replacement internal hinge is a mandatory procedure and not just a recommendation.
Choice of spare parts: original or analogue
Spare parts market for Nissan Qashqai offers a wide selection of internal CV joint options, from dealer originals to budget analogues. The original part is indicated by a number 39320-1HF0A (для правого привода) и отличается идеальным качеством материалов и сборки. However, the cost of the original is often too high, which forces drivers to look for alternatives. It is important to understand that cheap Chinese fakes often cannot withstand even 10-15 thousand kilometers, quickly deteriorating due to the low quality of the steel.
Among reliable analogues, experts highlight brands Spicer, GKN, Loebro and Febi. These manufacturers are often suppliers to the assembly line, so their products are not inferior to the original in terms of resource, but are much cheaper. When purchasing, be sure to check the integrity of the packaging and the presence of all necessary tags. It is unacceptable to purchase a CV joint without a protective cover, since lubricant must be applied at the factory in compliance with temperature conditions.
It is also worth paying attention to the type of connection. On Nissan Qashqai J10 используются шлицевые соединения, которые должны входить в ступицу и коробку передач с определенным усилием. If you purchase an assembled axle shaft, check the length of the splines and the condition of the retaining ring. Sometimes it is more profitable to buy only the hinge itself and the boot, and use the old axle shaft after pressing, if it does not have deep burrs.

Tools and workplace preparation
To successfully replace the right inner CV joint, you will need a set of specialized tools. A regular home kit may not be able to handle soured bolts or may require excessive force, which can lead to injury. It is imperative to have a jack with a high lifting capacity, since the weight of the axle shaft and the need to suspend the engine require reliable fixation. Use socket set with extensions and wrenches, as well as wrenches for unscrewing the hub nut.
A critical element is the circlip remover and CV joint mandrel. Trying to hammer a new hinge along the splines or through a piece of pipe can deform the seat and lead to rapid destruction of the unit. You will also need mounting spatulas, a wheel wrench, WD-40 or similar penetrating lubricant, and a new set of subframe bolts, as old ones often break off or become warped during removal.
Не забудьте подготовить трансмиссионное масло для доливки после работ. При извлечении полуоси из коробки передач часть масла неизбежно вытечет. The volume of fluid to be drained depends on the design of the differential, but on average you need to prepare about 0.5–1 liter of oil. A sealant for gasketing a tray or box lid is also useful if the dismantling process requires the removal of protective elements.
- Jack and safety stand ("tragus")
- Socket set: 12, 14, 17, 19, 21, 24 mm
- Retaining Ring Puller (Internal Type)
- Hammer and mandrel for pressing in CV joint
- Mounting blade and hub nut wrench
☑️ Preparation for replacement
Step-by-step instructions for dismantling and installation
Первым этапом работы является безопасное поднятие автомобиля и снятие правого переднего колеса. Unscrew the hub nut while the machine is standing on the ground, since when unscrewing it in weight, it will turn along with the disc. After raising the car on a stand, unscrew the bolts securing the ball joint and steering tip to free the hub. Carefully move the steering knuckle to the side without twisting the brake hose.
Next, you need to unscrew the subframe mounting bolts on the right side. This is done in order to lower the subframe a few centimeters and gain access to the inner CV joint. Be extremely careful as the subframe is heavy and may fall suddenly. After freeing up the space, unscrew the bolt securing the boot clamp and carefully remove the inner joint from the gearbox. If it is stuck, use a prying tool to pry up the drive housing, but do not apply excessive force to the gearbox seal.
Removing the old CV joint from the axle shaft requires the use of a special puller or mandrel. Fix the axle shaft in a vice and knock out the old hinge, being careful not to damage the splines. Clean the seat from dirt and old grease. Install a new boot and snap ring onto the axle shaft. Press in the new CV joint using a mandrel, striking the end of the inner housing, but never hitting the splines or outer race.
Installation of the assembled unit is carried out in the reverse order. Insert the splined part of the axle shaft into the hub, then carefully, using a mounting blade, insert the inner CV joint into the differential until the retaining ring clicks. Убедитесь, что полуось полностью вошла в зацепление. Lock the hub nut and tighten the subframe bolts to the required torque. Don't forget to check the gearbox oil level after completing work.
How to check if the retaining ring is installed correctly?
After installing the axle shaft in the gearbox, try to pull it out by hand. If it comes out easily without a click, the ring did not work or is damaged. Нужно проверить посадку кольца и повторить процедуру вставки до упора.
⚠️ Attention: When inserting the axle shaft into the gearbox, there is a risk of damage to the differential seal. Если вы чувствуете сопротивление, не применяйте силу, а проверьте положение стопорного кольца и чистоту шлицов.
Before starting work, take photographs of the position of the subframe bolts and hoses to avoid confusion during assembly. Это особенно актуально для старых автомобилей, где детали могут иметь следы коррозии.
The nuances of working with a subframe and oil seals
One of the most difficult operations when replacing an internal CV joint is Nissan Qashqai J10 является работа с подрамником. To access the right-hand drive, it is often necessary to lower the subframe, which requires unscrewing several mounting bolts. Use a hydraulic strut or a sturdy stand to smoothly lower the subframe 5-10 cm.
При демонтаже полуоси из корпуса коробки передач высока вероятность повреждения сальника. If after installing a new CV joint you find an oil leak, the oil seal will have to be replaced. This will require additional removal of the axle shaft and the use of a mandrel to press in a new seal. Try to work carefully, without scratching the surface of the oil seal and the axle shaft splines. Even microscopic burrs on the splines can lead to rapid seal wear and oil leakage.
Также стоит уделить внимание состоянию пыльника внутреннего ШРУСа. Even if you only replace the hinge, the old boot is often damaged or deformed. Use a new set of clamps, but do not tighten them too much so as not to squeeze the rubber. Check the tightness of the connection, making sure that the grease is not squeezed out from under the edges of the boot when the wheel moves. A correctly installed boot is a guarantee of long service life of the new unit.
Lowering the subframe requires care and secure support. Never work under a vehicle supported solely by a jack and use safety stands on the subframe.
Проверка качества работ и тестовая поездка
After completing all work to replace the right inner CV joint, a thorough inspection must be carried out before the first trip. Убедитесь, что все болты затянуты с требуемым моментом, особенно ступичная гайка и болты крепления подрамника. Проверьте уровень трансмиссионного масла и при необходимости долейте его до нормы. Visually inspect the installation location for oil leaks or improper boot position.
The first trip should be careful. Выезжайте из гаража и аккуратно разгоняйтесь, прислушиваясь к звукам со стороны правой передней подвески. Vibration during acceleration should completely disappear. Drive over rough surfaces a few times and try making smooth turns to make sure there are no knocking noises. If the vibration persists, the problem may not be with the CV joint, but with wheel balancing or the condition of other suspension components.
В процессе эксплуатации в первые 1000 километров рекомендуется периодически проверять состояние нового узла. Pay attention to the absence of traces of grease on the wheel rim and the absence of extraneous sounds. If you notice the slightest sign of malfunction, stop immediately and re-inspect. Своевременное выявление проблемы позволит избежать серьезных поломок и дорогостоящего ремонта в будущем.
- Check the gearbox oil level
- Make sure there are no leaks from under the oil seal
- Затяните ступичную гайку динамометрическим ключом
- Check the condition of the boot and clamps
⚠️ Attention: Ignoring vibration during acceleration can lead to the destruction of the differential spline, which will require a major overhaul of the transmission.
Frequently asked questions (FAQ)
Is it necessary to replace the axle shaft assembly or is it only possible to replace the CV joint?
Only the inner CV joint can be changed if the axle shaft itself does not have deep scoring, corrosion or bending. However, often when the inner joint is heavily worn, the axle shaft splines are also damaged. In this case, it is more profitable and reliable to install the axle shaft assembly, as this saves time on pressing and eliminates the risk of damage to the splines when dismantling the old unit.
Why did the vibration not disappear after replacement?
If vibration remains, check that the retaining ring is installed correctly. Оно могло не защелкнуться, и полуось находится не до конца. The cause may also be wheel imbalance, damaged outer CV joint or wear on the subframe silent blocks. Рекомендуется провести полную диагностику ходовой части.
How much oil leaks when replacing a CV joint?
The amount of oil leaking depends on the design of the gearbox and the position of the vehicle. Typically, 0.3 to 0.7 liters leak out. Обязательно приготовьте свежее масло для доливки, чтобы уровень не упал ниже минимальной отметки, что может привести к перегреву и поломке дифференциала.
Можно ли использовать старую смазку для нового ШРУСа?
Absolutely not. Lubricant for CV joints has specific additives for operation under conditions of high loads and temperatures. Using old or unsuitable lubricant (for example, lithol) will cause rapid wear of the joint. Always use the lubricant included with the new CV joint or recommended by the manufacturer.
How often should boots be checked?
Рекомендуется осматривать пыльники ШРУСов при каждой замене масла или раз в 10-15 тысяч километров. A damaged boot is a direct route to abrasive getting inside the assembly. Timely replacement of the boot costs a penny, but saves an expensive CV joint from destruction.
