The boot of the internal CV joint (constant velocity joint) on Nissan Qashqai J10 - a part that often fails due to natural wear or mechanical damage. Its malfunction leads to dirt and moisture getting into the mechanism, which accelerates the destruction of the hinge itself and can result in expensive repairs. In this article we will look at how Correctly replace the inner CV joint boot on Qashqai J10 with your own hands, without resorting to the services of a car service.
The procedure requires accuracy and knowledge of key nuances: from choosing a high-quality boot to correct installation of clamps. We will look at all stages - from fault diagnosis to final assembly, and also talk about typical mistakes that beginners make. If you notice cracks on the boot, traces of grease on the inside of the wheel, or a characteristic crunch when turning, these instructions are for you.
Signs of a malfunction of the inner CV joint boot on a Qashqai J10
The first signal about problems with the boot is visual damage: cracks, tears or complete destruction of the rubber boot. However, it is not always possible to notice a defect immediately. Indirect signs that should alert you:
- 🔍 Lubrication on the inside of the wheel or arch — if the boot is torn, the CV joint grease splashes out when moving.
- 🔊 Crunching or clicking noise when turning, especially with the steering wheel fully turned. This indicates dirt has gotten into the joint.
- 🚗 Vibration or jerking during acceleration - a worn CV joint can cause a beating that is transmitted to the body.
- 🔧 Backlash in the drive when checking by hand (if you rock the shaft with the wheel removed).
On Qashqai J10 The inner CV joint suffers less often than the outer one, but its boot also requires attention. Used cars are especially vulnerable more than 100,000 km or used in off-road conditions. If you ignore the problem, the consequences will be serious: from accelerated wear of the joint to its complete destruction and the need to replace the entire drive.
⚠️ Attention: A crunch when moving backwards when cornering is almost a 100% sign of a faulty internal CV joint. In this case, replacing the boot may no longer save you; diagnostics of the hinge itself will be required.
What tools and spare parts will be needed
To replace the inner CV joint boot with Nissan Qashqai J10 you will need:
| Category | Name | Notes |
|---|---|---|
| Tools | Jack and stops | Be sure to use safety stands! |
| Tools | Socket set (17, 19, 30 mm) | For unscrewing the hub nut and CV joint bolts |
| Tools | Mount or puller for CV joint | Helps remove the joint from the shaft without damage |
| Spare parts | Inner CV joint boot | Original Nissan 39310-4M000 or analogues: GKN, Febi, SKF |
| Consumables | Grease for CV joints | Recommended Molykote BR2 Plus or analogues |
When choosing a boot, give preference to original parts or proven brands. Cheap analogues often break after 10–20 thousand km. Also prepare new clamps — old ones are not reused after removal. If you plan to replace the lubricant, buy it with a reserve (about 100–150 g per CV joint).

Step-by-step instructions for replacing the boot
The process of replacing the inner CV joint boot with Qashqai J10 can be divided into several key stages. It is important to follow the sequence to avoid damaging the drive or other suspension components.
1. Preparing and removing the wheel
Place the car on a flat surface, secure it with wheel chocks and loosen the hub nut (it is tightened with a large torque!). Then jack up the car and remove the wheel. For ease of operation, it is recommended to unscrew the steering end and move the stand to the side.
2. Dismantling the drive
Unscrew the bolts securing the inner CV joint to the gearbox (usually 3 bolts of 17 or 19 mm). Carefully remove the hinge from its seat using a pry bar. Be careful not to damage the gearbox seal! Then remove the outer CV joint from the hub (a puller may be required).

3. Replacing the boot
Cut off the old clamps and remove the damaged boot. Thoroughly clean the drive shaft of old grease and dirt. Put on the new boot, after applying lubricant to the CV joint (if replacement is required). Install the new clamps, making sure they fit tightly around the boot. Important: clamps must be tightened without distortions, otherwise the boot will quickly tear.
⚠️ Attention: If, when examining the CV joint, you find play or chips on the balls, it is useless to change the boot - the entire joint must be replaced. Check this by rocking the shaft in different planes.
4. Assembly and testing
Install the drive in reverse order. Pay special attention to the tightening torque of the hub nut (approx. 200–220 Nm for Qashqai J10). After assembly, check the operation of the CV joint while driving: accelerate to 20–30 km/h and make several turns. There should be no crunching or vibration.
Before installing the boot, apply a thin layer of lubricant to its inner surface - this will facilitate installation and protect the rubber from cracking.
Common mistakes and how to avoid them
Even experienced car owners sometimes make mistakes when replacing the CV joint boot. Here are the most common ones and how to prevent them:
- 🔧 Incorrect tightening of clamps — if the clamp is loosely tightened, the boot will slide off; if you tighten it, it will break. Use special crimping pliers.
- 🧴 Saving on lubrication - cheap analogues dry out quickly, which leads to accelerated wear of the CV joint. Take only specialized formulations.
- 🔩 Ignoring play in the CV joint — if the hinge is already worn out, replacing the boot will not solve the problem. Always check the play before installing a new cover.
- 🔄 Mixed up bolts during assembly — the bolts securing the CV joint to the gearbox have different lengths. Reinstall them in their original places, otherwise you risk damaging the threads.
Another common mistake is gearbox seal damage when removing the drive. To avoid this, use a plastic puller or carefully pry up the CV joint with a pry bar without applying force to the box body.
What happens if you don’t replace a torn boot on time?
If you ignore damage to the boot, dirt and moisture will get into the CV joint, which will lead to corrosion and accelerated wear of the balls and races. In the best case, the hinge will begin to crunch, in the worst case, it will jam or collapse right on the move. Repair in this case will cost 3–5 times more than timely replacement of the boot (from 8,000 to 20,000 rubles versus 1,500–2,500 rubles).
Cost of work in a car service vs self-repair
The price of replacing the inner CV joint boot with Nissan Qashqai J10 in car services varies depending on the region and level of the service station:

- Original boot - ~1,200–1,800 rubles.
- Clamps - ~200–400 rubles.
- Lubrication - ~300–500 rubles.
Total: 1,700–2,700 rubles versus 3,000–5,000 rubles for the service. The savings are obvious, but only if you are confident in your abilities.
Replacing the inner CV joint boot on a Qashqai J10 yourself is justified if you have the tools and minimal experience. If you have never worked with a drive, it is better to entrust the work to professionals to avoid errors during assembly.
Recommendations for caring for the CV joint after replacing the boot
To make sure your new boot lasts a long time, follow these tips:
- 🚿 Avoid deep puddles — sudden changes in temperature and water reduce the service life of rubber.
- 🔧 Check boots every 10,000 km for cracks or lubricant leaks.
- 🛣️ Try not to load the drive sudden starts or off-road driving at high speed.
- 🧴 Use quality lubricant — it protects the CV joint from corrosion and reduces friction.
If you drive on dirt roads frequently, consider installing polyurethane anthers. They are more expensive than rubber ones, but 2-3 times more durable. It is also useful to do after replacing the boot wheel alignment, since removing the drive may affect the wheel alignment angles.
FAQ: Frequently asked questions about replacing the CV joint boot on the Qashqai J10
Is it possible to drive with a torn inner CV joint boot?
It’s possible for a short time (1-2 days), but it’s not worth the risk. Dirt and moisture will quickly destroy the CV joint, and instead of replacing the boot for 2,000 rubles, you will have to change the entire drive (from 15,000 rubles). If the boot breaks on the road, try to get to the garage or service center without making sharp turns or high speeds.
What is the best lubricant to fill the CV joint on the Qashqai J10?
The best option is Molykote BR2 Plus (original lubricant for CV joints Nissan). Alternatives: LIQUI MOLY LM47 or Castrol Optitemp BT. Do not use cheap all-purpose lubricants (for example, Litol-24), they cannot withstand loads and temperatures.
Do I need to change the clamps when replacing the boot?
Yes, definitely! Old clamps lose their elasticity and do not provide a tight seal. Even if they look normal, they may burst when crimped. New clamps cost a penny, but guarantee reliable fixation of the boot.
How long does it take to replace the inner CV joint boot?
If you have the tools and experience - about 2-3 hours. Beginners may need 4-5 hours, especially if they have to deal with stuck bolts or difficulty removing the drive. Take your time to avoid damaging the parts.
Is it possible to replace the boot without removing the drive?
Theoretically it is possible, but in practice it is extremely inconvenient and fraught with errors. Without removing the drive, you will not be able to properly clean the CV joint from old grease, check it for play and evenly distribute the new grease. It’s better to spend an extra 30 minutes on dismantling, but do it right.
