Nissan X-Trail T31 (2007–2013) is one of the most popular crossovers on the Russian market, but even its reliable suspension requires attention. Particularly vulnerable outer CV boot — a rubber cover that protects the constant velocity joint from dirt, moisture and mechanical damage. Its rupture or crack leads to the entry of abrasive into the mechanism, which leads to accelerated wear of the CV joint and expensive repairs.

In this article we will look at how to identify the problem in time, select a high-quality boot (including original articles and analogues), and also step by step replace it yourself - taking into account the nuances X-Trail T31 with petrol (MR20DE, QR25DE) and diesel (M9R) engines. We will separately focus on typical mistakes when replacing and ways to extend the life of a new boot.

Signs of a malfunction of the outer CV joint boot

The first symptoms of anther damage often go unnoticed until crunch when turning - signal about critical wear of the CV joint. To avoid this, pay attention to:

  • 🔍 Cracks or tears in the rubber — visible during visual inspection (preferably on a lift or inspection pit).
  • 💨 Lubricant on the inside of the wheel — if the boot is torn, it splashes when moving.
  • 🔊 Extraneous sounds - Creaking or crackling noise when turning the steering wheel at low speeds.
  • 🛑 Vibration on the steering wheel - occurs due to an imbalance caused by damage to the CV joint.

On Nissan X-Trail T31 with all-wheel drive (4WD) the risk of damage to the anthers is higher due to the increased load on the front axle. Cars with a mileage of more than 100,000 km are especially vulnerable - the rubber of the boots loses elasticity and cracks even without mechanical stress.

⚠️ Attention: If you ignore boot cracks, after 1–2 thousand km you may need to replace the entire CV joint (cost from 8,000 ₽ for the original). At the first sign of damage to the cover it urgently needs to be replaced and check the condition of the hinge.
📊 How often do you check the condition of the CV joint boots on your car?
  • Every 10,000 km
  • Once a year
  • Only when symptoms appear
  • Never checked

Articles and analogues: what to choose for X-Trail T31

Original anthers from Nissan guarantee a perfect fit, but their price (from RUB 1,500 per piece) often forces owners to look for analogues. Below is a table with proven options for external CV joints:

Type Article Manufacturer Price, ₽ Notes
Original 39300-4M000 (right)
39300-4M001 (left)		 Nissan 1 500–2 000 Best quality tires, but high price
Analogue JTC3145 JTC 600–800 Good elasticity, suitable for harsh climates
Analogue SKF VKJA 6636 SKF 900–1 200 Reinforced design, clamps included
Budget 2100-3145 GSP 400–500 Suitable for temporary replacement

When choosing an analogue, pay attention to:

  • 🔹 Material - optimal heat resistant rubber or polyurethane (lasts longer in cold weather).
  • 🔹 Complete set — the kit should contain clamps and lubricant for the CV joint (for example, Molykote BR2 Plus).
  • 🔹 Installation side — the right and left anthers are not interchangeable!
💡

Before purchasing, check whether the boot is suitable for your modification X-Trail T31. For example, for diesel versions (M9R) may require reinforced boots due to higher torque.

Tools and preparation for replacement

To replace the outer CV joint boot with Nissan X-Trail T31 you will need:

Jack and supports (or lift)

17, 19 and 32 mm wrenches

Torx T30 socket (for some fasteners)

Hammer and wooden spacer

Clamp pliers

Grease for CV joint (200–300 g)

Cleaner (eg. WD-40 or kerosene) -->

Before starting work:

  1. Place the car on a flat surface and secure the rear wheels.
  2. Loosen the hub nut (you will need a wrench 32 mm and extension cord).
  3. Remove the wheel and clean the drive shaft from dirt.
⚠️ Attention: Don't start disassembling if you don't have it at hand. new clamps! Old disposable clamps cannot be reused - they will not provide a tight seal.

On X-Trail T31 with AWD (all-wheel drive) before removing the drive shaft, it is necessary to drain the oil from the transfer case (about 0.5 l). Otherwise, when removing the shaft, the oil seal may squeeze out.

How to drain oil from transfer case?

1. Place a container under the drain plug (it is located at the bottom of the transfer case).

2. Unscrew the plug with the key on 24 mm.

3. Wait until the oil is completely drained (10–15 minutes).

4. Screw on the plug with a new gasket (part no. 38342-4M000).

Step-by-step instructions for replacing the boot

Algorithm for replacing the outer boot with Nissan X-Trail T31 (using the example of the left side):

  1. Removing the hub nut:

    Completely unscrew the nut (previously loosened) and remove the thrust washer. If the nut does not budge, use WD-40 and lever.

  2. Disconnecting the ball joint:

    Unscrew the two ball mounting bolts (key on 17 mm) and press the pin out of the steering knuckle using a puller.

  3. Removing the Drive Shaft:

    Carefully pull the shaft out of the hub, first moving it to the side. Be careful not to damage the boot of the inner CV joint!

  4. Replacing the boot:

    Cut off the old clamps, remove the damaged boot and clean the CV joint from old grease. Put on a new cover, secure with clamps and fill with fresh lubricant (150–200 g).

During assembly:

  • 🔧 Make sure that the shaft is seated in the hub splines all the way - otherwise there will be vibration when moving.
  • 🔧 Tighten the hub nut to torque 250–270 Nm (use a torque wrench!).
  • 🔧 After replacement, check wheel angle - Even a slight misalignment can lead to uneven tire wear.
💡

On X-Trail T31 with diesel engine (M9R) drive shafts are longer than on gasoline versions. Make sure that the boot you purchase is suitable for your modification!

Typical replacement mistakes and how to avoid them

Even experienced car owners make mistakes that shorten the service life of a new boot. Let's look at the most common ones:

  1. Using old clamps:

    Disposable clamps lose their elasticity after removal. Always install new ones (article 39398-4M000 for the original).

  2. Not enough lubrication:

    If the CV joint is “dry”, it will wear out quickly. Norm - 150–200 g lubricants on one joint.

  3. Damage to boot during installation:

    Do not use screwdrivers or other sharp objects to refill the case - only plastic spatulas.

  4. Improper tightening of the hub nut:

    Weak tightening leads to play, excessive tightening leads to bearing deformation. Use a torque wrench!

Another common problem is boot distortion during installation. To avoid this, before fixing the clamps, rotate the shaft by hand so that the boot fits evenly.

How to extend the service life of a CV joint boot

Average boot life per Nissan X-Trail T31 — 50,000–80,000 km, but with proper care it can be increased to 100,000+ km. Tips:

  • 🚗 Regular washing — Dirt and salt accelerate the destruction of rubber. Wash wheel arches every 2–3 weeks in winter.
  • 🔧 Checking the clamps — loose clamps allow moisture to pass through. Pull them up every 10,000 km.
  • 🛡️ Protective compounds - treat the anthers with silicone grease (for example, Liqui Moly Silicone-Spray) to protect against cracking.
  • 🚘 Careful driving — avoid sudden starts and turns at maximum steering angle (increases the load on the CV joint).

For diesel versions (M9R) it is recommended to install reinforced polyurethane boots — they better tolerate high loads and temperature changes.

💡

If you often drive off-road, install additional protection plates on anthers (for example, from Febi or Meyle). They prevent punctures from stones and branches.

Cost of work in the service vs independent replacement

The cost of replacing the outer CV joint boot by Nissan X-Trail T31 in services in Moscow and regions:

Service type Cost (for 1 side), ₽ Opening hours Warranty
Official dealer 3 500–5 000 1.5–2 hours 12 months
Independent service 2 000–3 500 1–1.5 hours 6 months
On your own 500–1,500 (spare parts) 2–3 hours —

Self-replacement is beneficial if you have:

  • ✅ Tools (jack, wrenches, ball puller).
  • ✅ Experience with suspension (or willingness to learn).
  • ✅ Time and patience (the first replacement may take up to 3-4 hours).

If at least one item is missing, it is better to contact the service. Errors during replacement will cost more than savings (for example, damage to the CV joint or wheel bearing).

FAQ: Frequently asked questions about CV joint boots X-Trail T31

Is it possible to drive with a torn boot?

Short-term (1-2 days) - yes, but only if the CV joint is not crunching yet. Driving for a long time will cause dirt to get into the joint and its irreversible wear and tear. The maximum is to get to the service center, avoiding puddles and dust.

What kind of lubricant should I fill the CV joint?

Optimal options:

  • Molykote BR2 Plus - original lubricant for Nissan.
  • LIQUI MOLY LM47 — universal, suitable for harsh conditions.
  • Castrol LMX - a budget analogue with good reviews.
Do not use Litol or Solidol - they cannot withstand high temperatures in the CV joint.

Do I need to change the inner boot if the outer one is torn?

Not necessary if the inner case is intact. However, with a mileage of more than 150,000 km It is recommended to inspect it too - they often wear out at the same time. Replacing the inner boot is more difficult (removing the box or axle shaft is required).

What is the difference between anthers for gasoline and diesel engines? X-Trail T31?

Main differences:

  • Length - on diesel versions (M9R) drive shafts are longer by 20–30 mm.
  • Material — for diesel engines, reinforced covers are often used (for example, polyurethane).
  • Clamps — may differ in diameter (check the catalogue).

Install anthers from the petrol version to the diesel version it's impossible!

How to check the CV joint after replacing the boot?

Take the test:

  1. Turn the steering wheel all the way left/right.
  2. Get moving and listen - there shouldn't be any crunch.
  3. Accelerate to 20–30 km/h and repeat the maneuver.

If appeared click or crunch, this means that the CV joint is already worn out and requires replacement.
