Internal boot CV joint (constant velocity joint) on Nissan Qashqai J10 - This is a part that often fails due to natural wear, mechanical damage or careless operation. A ruptured boot allows dirt and moisture to enter the mechanism, which accelerates wear. tripoid and can cause costly repairs. In this article we will look at how to independently replace the inner CV joint boot with Qashqai J10 (2007–2013), without resorting to car service services.
The procedure does not require special skills, but will require care and strict adherence to instructions. We will look at the necessary tools, disassembly steps, the nuances of installing a new boot and typical mistakes that beginners make. You will also learn how to check the condition of the CV joint after replacement and when you should think about completely replacing the joint.
Signs of a malfunction of the inner CV joint boot
The first symptoms of boot damage often go unnoticed until the problem develops into a serious breakdown. Look out for the following signs:
- 🔊 Crunching or grinding noise when cornering or when starting from a stop - indicates that dirt has entered the CV joint.
- 💨 Lubrication on the wheel or arch — if you notice black spots near the drive, the boot is most likely torn.
- 🔧 Vibration on the steering wheel during acceleration - may indicate play in the hinge due to wear.
- 🚗 Lubricant leak from under the boot - check the condition of the rubber by touch (cracks, tears).
If you ignore these symptoms, everything may need to be replaced after 1–2 thousand kilometers. internal CV joint, which will cost 3–5 times more than simply replacing the boot. On Nissan Qashqai J10 The internal CV joint fails less often than the external one, but its diagnosis is more difficult due to its location next to the gearbox.
⚠️ Attention: If during inspection you find metal shavings in the CV joint lubricant, this means that the tripoid has already begun to deteriorate. In this case, replacing the boot will not help: a complete replacement of the hinge will be required.
Tools and materials for replacement
To work you will need:
| Tool/material | Purpose | Note |
|---|---|---|
| Jack and stops | Lifting the car | Use only on a flat surface |
| Socket wrenches (17, 19, 30 mm) | Unscrewing the hub nut and bolts | Preferably with an extension cord |
| Mount or puller | Removing the drive from the gearbox | Plastic puller is preferable |
New boot (item no. 39310-4M00A) |
Replacement of damaged | Check compatibility with J10 |
| CV joint lubricant (for example, LIQUI MOLY LM47) | Refilling the hinge | Do not use graphite lubricant! |
Also prepare WD-40 for unscrewing soured bolts, rags and plastic ties for fixing the boot. If you plan to remove the drive completely, you may need special puller for inner CV joint (article Nissan 09931-7S000).
- Every 10,000 km
- Once a year
- Only when a crunch appears
- Never checked
Step-by-step instructions for replacing the boot
The replacement process can be divided into 3 stages: removing the drive, replacing the boot and reassembling. Let's look at each step in detail.
1. Dismantling the drive
Raise the car on a jack and remove the wheel. Unscrew the hub nut (you will need a wrench 30 mm and extension cord). Then:
- Disconnect tie rod end from the steering knuckle (use a puller).
- Unscrew the fastening bolts ball joint (key to
17 mm). - Remove the drive from the hub by gently tapping it through the wooden spacer with a hammer.
- Remove internal CV joint from the gearbox using a pry bar (do not apply force to the boot!).
If the drive does not come out of the gearbox, check to see if there is a retaining ring left inside. On Qashqai J10 it often sticks to the shaft.

2. Replacing the boot
Carefully cut off the old boot ties and remove it from the shaft. Clean the CV joint from old grease and inspect for wear. If the tripod rollers are worn out, the hinge must be replaced.
Installing a new boot:
- Apply new grease to tripoid (about 80–100 grams).
- Place the new boot onto the shaft, securing the small side with a plastic tie.
- Install the boot onto the CV joint housing and tighten the large tie rod.
- Check that the boot is not twisted or kinked.
Before installing the boot, apply a thin layer of lubricant to its inner surface - this will extend the life of the rubber and make installation easier.
3. Assembly and testing
Install the drive back into the gearbox (the latch should click) and reassemble the unit in the reverse order. After assembly:
- 🔧 Check it out shaft play - it shouldn't exist.
- 🚗 Ride 5–10 km and listen for any extraneous sounds.
- 🔍 Inspect the boot for any kinks after the test ride.
⚠️ Attention: If, after replacing the boot, a crunching sound appears when turning, it means that you did not clean the CV joint well enough of the old lubricant or used a low-quality compound. Repeat the procedure with kerosene washing.
Typical mistakes when replacing anther
Even experienced car owners make mistakes that lead to repeated repairs. Here are the most common:
- 🔧 Insufficient cleaning of the CV joint - Remaining dirt will quickly destroy the new boot.
- 🔩 Weak tightening of ties — the boot will slide off when moving.
- 🛠️ Using the wrong lubricant — graphite or lithol lubricant is not suitable for CV joints.
- 🚗 Boot distortion during installation - leads to rapid wear.
On the Nissan Qashqai J10, people especially often forget to check the condition of the gearbox seal after removing the drive. If it is worn out, oil will leak through it, which will lead to contamination of the new boot.
What to do if the boot ties don't hold?
If plastic ties are slipping, use metal clamps (but don't overtighten!). An alternative is special ties for CV joints with a toothed lock (item no. 39390-4M000).
When is it necessary to replace the entire CV joint?
Replacing the boot is justified only if the problem is diagnosed early. If you find at least one of the following signs, get ready to replace the entire hinge:
- 🔊 Constant crunching when moving forward/backward.
- 🔧 Backlash in tripoid (checked by hand with the boot removed).
- 💥 Destruction of rollers or CV joint housings.
- 🔥 Drive overheating after the trip (the boot is hot to the touch).
On Qashqai J10 the original internal CV joint costs about 8–12 thousand rubles (item number 39300-4M000), analogues (for example, GKN or SKF) - 20–30% cheaper. Replacement takes 1.5–2 hours and does not require special tools.
If chips or wear are visible on the tripoid rollers, there is no point in changing the boot. In this case, only a complete replacement of the CV joint will save you from expensive transmission repairs.
Comparison of the original boot and analogues
When choosing anther, many are faced with a dilemma: to buy an original or an analogue. Let's look at the pros and cons of each option:
| Boot type | Pros | Cons | Service life |
|---|---|---|---|
Original (39310-4M00A) |
Perfect fit, quality tires | High price (RUB 1,500–2,000) | 80–100 thousand km |
GKN (501 026) |
Good quality, more affordable than the original | May be harsher at low temperatures | 60–80 thousand km |
SKF (VKJA 6633) |
Reinforced rubber, oil resistant | Rarely found in stores | 70–90 thousand km |
| Budget analogues (for example, Febi) | Low price (300–500 rub.) | Tans quickly, leaks are possible | 30–50 thousand km |
For Nissan Qashqai J10 the optimal choice would be the original or GKN. Budget analogues are only suitable for temporary replacement if you plan to sell the car soon.
