Inner right CV joint <em>Nissan X-Trail T31</em>: how to select, replace and avoid mistakes

Inner right CV joint (constant velocity joint) on Nissan X-Trail T31 - a unit that often fails after 100-150 thousand kilometers, especially during aggressive driving or operation in difficult conditions. Crossover owners are faced with a characteristic crunching when turning, vibrations at speed or even complete jamming of the drive. But how can you distinguish wear on the internal CV joint from the external one? What Article numbers of original and analog parts are suitable specifically for the right internal hinge? And why is replacing this node with T31 Does it have its own characteristics?

In this article we will analyze not only the signs of malfunction and the replacement process, but also the nuances that even experienced craftsmen are silent about. For example, why after installing a new CV joint there may be play in the box, how to properly lubricate the tripod (yes, this is critical!), and what errors lead to repeated failure of the unit after 20 thousand km. You will also find current prices for parts, comparison of brands (GKN, SKF, Febi) and step-by-step instructions with photos - from removing the drive shaft to pressing in a new CV joint.

Signs of malfunction of the inner right CV joint on Nissan X-Trail T31

Inner CV joint on X-Trail T31 breaks differently than the external one. If the outer hinge crunches when turning (especially on inverted wheels), then the internal one manifests itself differently. Here are the key symptoms:

• 🔊 Clunking or clicking noises when starting off or changing gears. The sound comes from the right front wheel, but can radiate into the cabin.
• 🌀 Vibration at speed 60-90 km/h, which disappears during acceleration or braking. Often confused with wheel imbalance!
• 🔄 Jerks during accelerationas if the car was “twitching”. This happens due to play in the tripod - the inner clip begins to “walk”.
• 🛑 Drive jammed when cornering (rarely, but happens when the CV joint is completely destroyed).

Important: on Nissan X-Trail T31 with model code CT31 (2.0/2.5 petrol, 2.0 diesel) internal CV joints not interchangeable with outsiders! The internal hinge has tripod design (three rollers on bearings), and the outer one is ball. Also, the right and left inner CV joints may differ in shaft length and attachment to the box.

⚠️ Attention: If you hear a crunching sound when moving backwards (especially with the wheels turned out), this is a 90% external CV joint. The internal one almost never crunches when reversing!

For an accurate diagnosis, lift the car on a lift or hang the right front wheel. Ask for an assistant pump the shaft manually — if there is play in the tripod (more than 0.5 mm), the CV joint must be replaced. Also inspect the boot: if it is torn and old grease and abrasive is visible inside, the assembly is already worn out.

Articles and analogues: what to put on X-Trail T31 instead of the original

Original inner right CV joint for Nissan X-Trail T31 (2007-2013) has an article number 39300-4M000 (for models with manual transmission) and 39300-4M001 (for automatic transmission). However, the original is from Nissan is expensive (from 8,000 rubles), so owners often choose analogues. Here are the tested options:

Brand	Article	Price, rub.	Features
GKN (LOEBRO)	ADG02933	4 500–5 200	The best analogue in terms of price/quality ratio. Includes high-quality boot and lubricant.
SKF	VKJA 7702	5 800–6 500	Premium option with reinforced tripod. Suitable for severe operating conditions.
Febi	28216	3 800–4 300	A budget option, but the anthers often break after 30-40 thousand km.
NTN-SNR	JJ401010	5 000–5 700	Good alternative GKN, but is less common in stores.

When choosing, pay attention to complete set: the box should contain the CV joint itself, boot, clamps and lubricant (usually 200–250 g). If there is no lubricant, it is a fake or a “light” version! Also check markings on the tripod: on the original and high-quality analogues, size numbers are stamped (for example, 24×58).

⚠️ Attention: On X-Trail T31 with diesel engine M9R (2.0 dCi) internal CV joints have a reinforced design. Original article number - 39300-4M010. Installing a “gasoline” CV joint on a diesel engine will lead to its rapid wear!

Tools and preparation: what you need for replacement

Replacing the inner right CV joint with Nissan X-Trail T31 requires special tools. Without it, you risk damaging the new joint or transmission. Here's the full list:

• 🔧 Set of sockets and keys (necessarily heads on 17, 19, 32 for the hub nut).
• 🔨 Hammer and bronze mandrel to knock the shaft out of the box.
• 🛠️ CV joint puller (For example, KUKKO 204-2 or similar). Without it, it is almost impossible to remove the old hinge.
• 🔗 Torque wrench for tightening the hub nut (torque - 250–270 Nm).
• 🧴 Grease for CV joints (For example, Molykote BR2 Plus or LIQUI MOLY LM47).
• 🔥 Gas burner or hair dryer for heating the box (makes removing the shaft easier).

Also prepare:

• 🚗 Jack and stops (or lift).
• 🧤 Gloves and rags — the grease from the CV joint is difficult to wash off.
• 📦 New clamps for boot (even if it is included in the kit, take it in reserve).

Before starting work necessarily:

1. Drain the oil from the manual transmission/transfer case (if you plan to remove the drive completely).
2. Clean the area around the box from dirt - sand getting inside will lead to wear of the seal.
3. Mark the position of the shaft relative to the box (for example, with a marker) - this will simplify reassembly.

Step-by-step instructions: how to replace the inner right CV joint

The replacement process takes 3–5 hours (depending on experience). The main thing is to take your time and follow the algorithm. Here are the detailed instructions:

Step 1: Removing the Wheel and Disconnecting the Hub

1. Lift the right front wheel, remove it and unscrew the hub nut (you will need an extension and a socket). 32).
2. Disconnect the brake caliper (it is not necessary to remove it completely, you can hang it on a wire).
3. Remove the brake disc and disconnect the steering knuckle from the steering knuckle.
4. Knock the ball joint out of the steering knuckle (use a puller or a hammer with a mandrel).
5. Pull the shaft out of the hub - you now have access to the inner CV joint.

Step 2. Removing the shaft from the box

This is the most difficult stage. The shaft “sticks” to the differential and needs to be carefully knocked out:

1. Unscrew the three bolts securing the inner CV joint to the box (head on 10 or 12).
2. Insert the mounting blade between the shaft and the box, and lightly tap the shaft with a hammer (through a bronze mandrel!).
3. If the shaft does not yield, heat the box around the seal with a hairdryer or torch (do not overheat!).
4. Once the shaft has moved, pull it out completely.

Step 3. Replacing the CV joint

1. Clamp the shaft in a vice (using soft jaws to avoid damage!).
2. Remove the old boot clamps, cut off the boot and clean the shaft of old grease.
3. Install the CV joint puller and compress the old joint. Be careful - the tripod may shoot out!
4. Place the new boot on the shaft and secure it with a clamp (do not tighten it completely).
5. Apply grease to the tripod of the new CV joint (approx. 100–150 g) and press it onto the shaft.
6. Place the boot on the CV joint, bleed the air and tighten the clamps.

Step 4: Reinstalling the shaft

1. Carefully insert the shaft into the box, aligning the splines.
2. Tighten the bolts securing the CV joint to the box (torque - 25–30 Nm).
3. Reassemble the hub in reverse order, tighten the hub nut with a torque wrench.

Step 5. Check after replacement

After assembly:

• Spin the wheel by hand - there should be no jams.
• Start the car and drive at low speed, listening to extraneous sounds.
• After 50–100 km, check the boot for leaks (there should be no traces of grease).

Typical replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes that shorten the service life of a new CV joint. That's what can't do on Nissan X-Trail T31:

• 🔧 Use old clamps. They lose their elasticity and do not ensure the seal of the boot.
• 🧴 Save on lubrication. Cheap analogues (such as Litola) do not withstand loads and turn into abrasive.
• 🔨 Hit the shaft directly with a hammer. This deforms the splines and leads to play.
• 🌀 Do not check the box seal. If it is worn out, oil will leak through it and ruin the new CV joint.
• 🔄 Install CV joint without alignment. The tripod must sit on the shaft strictly in the center, otherwise an imbalance will arise.

Another common problem is play in the box after replacement. This happens if:

• The bolts securing the CV joint to the box are not tightened sufficiently.
• The splines on the shaft or differential are damaged.
• The CV joint of the wrong size is installed (for example, from X-Trail T30).

If vibration appears at speed after replacement, check:

1. Wheel balancing (possibly lost during removal).
2. Condition of the hub bearing (play more than 0.05 mm unacceptable).
3. Centering the shaft in the box (sometimes the splines do not fully fit into place).

What to do if the new CV joint crunches immediately after installation?

If the crunch appears immediately, most likely:

1. Not enough lubrication in a tripod (must be at least 100 g).

2. The boot is damaged — check it for leaks.

3. Defective details (found in cheap analogues like Febi).

4. Incorrect pressing — The CV joint must sit on the shaft without play.

Solution: Remove the CV joint and check all points. If the part is defective, replace it under warranty.

Grease for CV joints: which one to choose and how to apply

Depends on the quality of the lubricant up to 50% resource internal CV joint. On Nissan X-Trail T31 cannot use regular Litol-24 or Solid oil - they cannot withstand high temperatures and loads. Optimal options:

Lubrication	Type	Benefits	Disadvantages
Molykote BR2 Plus	Molybdenum	High temperature resistance, reduces tripod wear.	Dear (from 800 rubles per tube).
LIQUI MOLY LM47	Lithium with molybdenum	Good adhesion, not washed out by water.	May thicken at -30°C.
Castrol LMX	Lithium	Universal, suitable for all CV joints.	Average heat resistance.
SLIPKOTE 220-R	Synthetic	Does not thicken in the cold, long service life.	Difficult to find in stores.

How to properly lubricate a CV joint:

1. Apply lubricant to the entire surface of the tripod (rollers and clip).
2. Fill with lubricant internal cavity of the boot (about 50 g).
3. Before installing the boot, squeeze out excess air so that there is no pressure.
4. After pressing the CV joint, add more 20–30 g lubricant through the hole in the boot (if any).

⚠️ Attention: Never use graphite lubricant! It is abrasive and quickly destroys the tripod. Also avoid lubricants with copper or aluminum — they oxidize and form solid deposits.

How long does a CV joint last? X-Trail T31 and how to extend its life

The service life of the inner CV joint is Nissan X-Trail T31 depends on operating conditions:

• 🚗 City riding (calm style): 150–200 thousand km.
• 🏔️ Off-road/aggressive driving: 80–120 thousand km.
• 🌡️ Extreme temperatures (extreme heat/cold): 100–150 thousand km.

How to extend the life of a CV joint:

• 🔧 Check the anthers every 20 thousand km. even a small crack will allow dirt to enter.
• 🚿 Wash drive shafts when changing the oil. Dirt on the boot accelerates its wear.
• 🛣️ Avoid abrupt starts with the wheels turned out, this is the maximum load on the tripod.
• 🔄 Lubricate the CV joint every time it is removed. (even if you are just checking the boot).

If you do a lot of off-road driving, consider installing reinforced CV joints from SKF or GKN with markings Heavy Duty. They have reinforced rollers and heat-resistant grease included.

Also note box seal condition. If it “sweats”, oil will fall on the CV boot and corrode it. When replacing the CV joint, it is recommended to change the oil seal (part number - 38345-4M000 for manual transmission).

FAQ: Frequently asked questions about the inner CV joint Nissan X-Trail T31

Is it possible to drive with a crisp CV joint?

For a short time (before the workshop) - yes, but it’s not worth the risk. A damaged CV joint can jam at speed, leading to an accident. It is especially dangerous if the tripod roller breaks off - the shaft will “shoot” out of the box and you will lose control of the car.

How to distinguish a faulty internal CV joint from an external one?

Inner CV joint does not crunch when turning, but produces a dull knock when starting off or vibration at speed. The external one crunches when the wheels are turned out (for example, when parking). Also, the inner CV joint often “gives” into the body, and the outer one into the wheel.

Do I need to replace both CV joints (inner and outer) at the same time?

Not necessary if the second one is in good condition. However, if the mileage is greater 150 thousand km, it is more logical to change both - the outer CV joint usually wears out a little later than the inner one.

Is it possible to restore the CV joint (for example, replace the rollers)? summary>

Theoretically yes, but in practice it is unprofitable. The cost of the repair kit (rollers, clip) is comparable to the price of a new CV joint from Febi or GKN. In addition, after repair, the resource of the node will be 2-3 times lower.

Why did vibration appear after replacing the CV joint?

The reasons may be:

1. Incorrect shaft balancing (for example, if the boot is put on crookedly).
2. Damaged splines on the shaft or in the box.
3. Insufficient tightening of the hub nut.
4. Defective new CV joint (found in cheap analogues).

Check all points, starting with the simplest (nut tightening).
