Constant velocity joints (CV joints) - one of the most loaded elements of the chassis Nissan X-Trail T31. These parts are responsible for transmitting torque from the gearbox to the wheels at different angles, ensuring a smooth ride even on off-road conditions. However, over time anthers are torn, the lubricant is washed out, and the mechanism itself wears out, which leads to a characteristic crunch and vibration.
Owners X-Trail T31 (2007–2013) often encounter problems with CV joints after 100–150 thousand kilometers, especially during aggressive driving or operation on Russian roads. In this article we will look at how accurately diagnose CV joint failure on T31 without a lift, which spare parts to choose (original vs analogue), and how to replace them yourself, saving up to 15 thousand rubles at a service station.
Signs of a CV joint failure on a Nissan X-Trail T31
The first symptom of CV joint wear is crunch when turning, especially with the steering column fully turned out. On X-Trail T31 with all-wheel drive (4WD), the problem often appears symmetrically on both sides, but more often it affects external CV joint (wheel side). Here are the key signs:
- 🔊 Crunching or clicking noise when turning left/right (even at low speed).
- 🌀 Steering wheel vibration when accelerating over 60 km/h (a symptom of wear on the inner CV joint).
- 💨 Lubricant on the inside of the wheel - a sign of a torn boot.
- 🚗 Jerks when starting off (if the inner CV joint tripod is worn out).
On X-Trail T31 with engines MR20DE (2.0 l) and QR25DE (2.5 l) CV joint crunching is often confused with a wheel bearing failure. To distinguish them, just drive in a straight line and turn sharply: if the sound intensifies, the CV joint is to blame.
⚠️ Attention: If you ignore the crunch of the CV joint T31, its debris can damage the axle shaft or even the gearbox. At the first signs, check the anthers - replacing them will cost 10 times less than repairing the consequences.

What CV joints are on the Nissan X-Trail T31: original vs analogues
On Nissan X-Trail T31 Two types of CV joints are installed:
- 🔄 External CV joint (wheel side) - hinge
Rzeppawith 6 balls. - 🔄 Inner CV joint (from the gearbox side) - tripod mechanism.
Original spare parts from Nissan have articles:
| CV joint type | Article | Cost (RUB) | Analogues |
|---|---|---|---|
| External (right/left) | 39310-4M000 | 8 000–12 000 | GKN (LOEBRO 100390), SKF (VKJA 7700) |
| Internal (right/left) | 39300-4M000 | 9 500–14 000 | Febi (22621), Mapco (61006) |
| Outer CV joint boot | 39381-4M000 | 1 200–1 800 | Corteco (20039001), Elring (463.530) |
| Lubrication kit | KL33-00001 | 500–800 | Molykote (BR2 Plus), LIQUI MOLY (LM47) |
Analogues from GKN or SKF often exceed the original in terms of service life (up to 200 thousand km), but require careful checking when purchasing - fakes are common. When choosing, pay attention to:
- 📦 Packaging (holograms, barcodes).
- 🔍 Marking on the CV joint body (must match the article number).
- 🛠️ Complete set (the box should contain clamps, lubricant, and a boot).
When purchasing a CV joint for X-Trail T31 check the length of the axle shaft - on models with automatic and manual transmission they differ by 10–15 mm!
Diagnostics of CV joint on X-Trail T31 without a lift
You can check the condition of the CV joint yourself, without resorting to the help of a service station. Here are step by step instructions for Nissan X-Trail T31:
- Visual inspection of anthers:
Turn the steering wheel all the way left/right and inspect the CV joint corrugation for breaks. If there are cracks or traces of grease, the boot must be replaced.
- Checking the backlash:
Jack up the car, grab the wheel at the 9 and 3 o'clock positions and swing it perpendicular to the axle. Play of more than 1–2 mm indicates wear of the CV joint.
- Crunch test:
Start the engine, engage first gear and drive away slowly with the steering wheel turned. A crunching noise under load is a sure sign of a malfunction.
On X-Trail T31 with all-wheel drive (All Mode 4x4-i) diagnostics are complicated by the presence of a transfer case. If the crunching sound is heard only when the 4WD, the problem may lie in the driveshaft or gearbox.
⚠️ Attention: Do not confuse the crunch of a CV joint with the sound of worn-out silent blocks of the front control arms! On T31 they make a squeaking sound when passing speed bumps, and the CV joint crunches precisely when turning under load.

Step-by-step replacement of the outer CV joint on a Nissan X-Trail T31
To replace the outer CV joint with X-Trail T31 you will need:
- 🔧 Set of heads (10, 12, 14, 17, 19 mm).
- 🔨 Hammer and pry bar.
- 🔑 Retaining ring remover (optional).
- 🧴 Lubrication
Molykote BR2 Plus(200 g). - 🛡️ New clamps for the boot.
Instructions:
Remove the wheel, unscrew the hub nut (you will need an extension and a lever).
Disconnect the ball joint and steering knuckle from the steering knuckle.
Drive the axle shaft out of the hub with a hammer through a wooden spacer.
Remove the boot clamps and clean the axle shaft from old grease.
Using a puller or pry bar, remove the retaining ring and the old CV joint.
Install a new CV joint, lubricate it (
150–180 glubricants), put on the boot and secure with clamps.Reassemble everything in reverse order, remembering to tighten the hub nut
200–220 Nm.
On X-Trail T31 with MR20DE (2.0 l) access to the left CV joint is difficult due to the battery - it will have to be removed. When replacing the inner CV joint, the entire axle shaft will need to be dismantled.
What happens if you don't replace the retaining ring?
Without a retaining ring, the CV joint may come off the axle shaft during a sudden jerk (for example, when towing). This will lead to loss of control and transmission failure.
Frequent mistakes when replacing a CV joint on a T31
Even experienced craftsmen make mistakes when working with CV joints Nissan X-Trail T31. Here are the most critical ones:
- 🔧 Retightening the hub nut — leads to bearing wear (maximum torque
220 Nm). - 🧴 Lack of lubrication — The CV joint will last no more than 20 thousand km.
- 🛡️ Reusing clamps — the boot will fly off after 500 km.
- 🔄 Installing a CV joint from another model (for example, from Qashqai J10) - misalignment of the splines will lead to vibration.
Another typical problem is incorrect pressing CV joint on the axle shaft. If it is not seated all the way, a metallic knock will be heard when moving. Check the gap between the CV joint housing and the retaining ring - it should be no more than 0.5 mm.
Use only original retaining rings - analogues often have less elasticity and do not securely fix the CV joint.
The cost of replacing a CV joint at a service station vs self-repair
Prices for replacing CV joints Nissan X-Trail T31 services vary depending on the region and type of service station:
| Type of work | Cost (RUB) | Time (hours) |
|---|---|---|
| Replacement of outer CV joint (1 side) | 4 000–7 000 | 1.5–2 |
| Replacing the inner CV joint | 6 000–10 000 | 2.5–3 |
| Replacing the boot + lubrication | 2 500–4 000 | 1–1.5 |
| Replacing the axle shaft assembly | 12 000–18 000 | 3–4 |
Replacing it yourself will cost 2–3 times cheaper, but will require tools and skills. For example, a kit for replacing an external CV joint (spare part + lubricant + clamps) will cost RUB 3,500–5,000, and work at a service station is still 5,000 rub..
If you have never repaired a chassis, it is better to entrust the replacement to professionals - errors when installing a CV joint on T31 may lead to emergency situation on the road.
Prevention: how to extend the life of the CV joint on the X-Trail T31
The service life of CV joints is Nissan X-Trail T31 can be increased to 200–250 thousand kmif you follow simple rules:
- 🛣️ Avoid abrupt starts with the wheels turned out (especially on ice).
- 🔧 Check the anthers every 15 thousand km - even a small crack will lead to dirt getting in.
- 🧴 Use only specialized lubricant (For example, Molykote BR2 Plus).
- 🚗 Don't ignore the vibrations — early diagnosis will save money.
On X-Trail T31 with all-wheel drive, pay special attention internal CV joints - they wear out faster due to the increased load when turned on 4WD. Regularly (every 60 thousand km) clean them of dirt and renew the lubricant.
After replacing the CV joint, be sure to perform a wheel alignment - even a slight change in the suspension geometry will affect tire wear.
FAQ: Frequently asked questions about CV joints on the Nissan X-Trail T31
Is it possible to drive with a crisp CV joint?
Short-term (1-2 weeks) - yes, but the risk of CV joint failure increases with each trip. On X-Trail T31 this may cause the wheel to lock at speed. At the first sign of crunching, check the boots and lubrication levels.
Which CV joint breaks more often on the T31 - left or right?
On X-Trail T31 with right-hand drive (Japanese assembly) wears out more often right outer CV joint due to greater load when turning. On European versions the wear is symmetrical.
Is it possible to restore the CV joint or just replace it?
Restoring (overhauling) the CV joint is possible, but impractical - the cost of the work exceeds the price of a new analogue. Exception: rare cases when only the boot is worn out, but the CV joint itself is in good condition.
What lubricant should I use for a T31 CV joint?
Optimal options:
- Molykote BR2 Plus (original for Nissan).
- LIQUI MOLY LM47 (universal, withstands -40°C).
- SKF LGMT 2 (for severe conditions).
Do I need to change the CV joint when replacing the axle shaft?
If the axle shaft is changed in the assembly (for example, due to deformation), then the CV joints are already installed. If you buy only an axle shaft without CV joints, transfer old parts only if they are in perfect condition (which is unlikely after 100 thousand km).
