Nissan X-Trail T31 (2007–2013) is one of the most popular crossovers on the Russian market, but even its reliable design is not immune to wear and tear of consumables. Engine mounts are a part that many people forget about until they experience vibrations, knocking noises, or even transmission damage. In this article we will look at how to recognize the problem in time, what supports are installed on T31 with different motors (QR25DE, MR20DE, M9R), and is it possible to cope with the replacement yourself.
Structurally, engine mounts (or “pillows”) dampen vibrations of the power unit, preventing the transfer of vibrations to the body and transmission. On X-Trail T31 There are usually three of them: two lateral (left and right) and one rear (sometimes called “box”). Wear of at least one of them leads to imbalance, which is especially dangerous for cars with CVT — here the risk of damage to the pulleys and belt increases significantly. Next, we’ll tell you how not to miss the first symptoms and avoid expensive repairs.
Signs of faulty engine mounts Nissan X-Trail T31
The first signals of problems with supports are often attributed to “minor problems,” but they cannot be ignored. Here are the key symptoms that should alert you:
- 🚗 Vibrations on the body when starting or stopping the engine, especially at idle speed. Often felt on the steering wheel or gearshift lever.
- 🔧 Metal knocks in the front of the vehicle when starting off or changing gears. The sound may sound like the crankcase being hit.
- 🔄 Motor "bouncing" when you suddenly release the gas or press the pedal, it is visually noticeable if you open the hood.
- ⚠️ Difficulty shifting gears (relevant for manual transmission) due to the displacement of the engine relative to the gearbox.
The signs are especially pronounced on X-Trail T31 with diesel engine M9R — due to the high torque at low speeds, the bearings wear out faster. Owners of petrol versions (QR25DE, MR20DE) more often encounter a problem after 150–200 thousand km, but with aggressive driving or frequent loads (for example, towing), the resource is reduced to 100 thousand km.
It is important to distinguish faulty supports from problems with drive shafts or suspension. For example, vibrations during acceleration may indicate wear on the CV joints, and knocking noises may indicate play in the silent blocks of the levers. To accurately diagnose supports, you will need a visual inspection or a test with an assistant (more on this in the next section).

How to check engine mounts for Nissan X-Trail T31 without lift
You can carry out diagnostics yourself, without resorting to the services of a service station. You'll need a flashlight, a pry bar (or a sturdy stick), and a helper. Follow this algorithm:
- Visual inspection: Open the hood and inspect the rubber support elements. Cracks, breaks or leakage of fluid from hydraulic supports - a clear sign of wear. Pay attention to the rear support - it is often hidden under the air filter.
- Backlash test: Ask an assistant to turn on the
Drive/Reverse(for automatic transmission) or 1st/reverse gear (for manual transmission), mientras you watch the engine. If the motor moves noticeably up and down or back and forth, the mounts will need to be replaced. - Checking with a pry bar: Use a pry bar to pry up the engine in the area where the support is attached (do not use excessive force!). If the support “sags” or makes a creaking noise, it’s time to change it.
For more accurate diagnosis, you can use vibration analysis stand, but this is already a task for the service. At home, pay attention to uneven wear of rubber supports - if one side is compressed more than the other, this indicates a permanent overload (for example, due to improper installation or deformation of the fasteners).
⚠️ Attention: On X-Trail T31 with variator JF011E worn supports can lead to belt slippage and overheating of the box. If, along with vibrations, jerks appear during acceleration, immediately check the condition of the airbags!

What engine mounts are installed on Nissan X-Trail T31
On X-Trail T31 The mounts differ depending on the type of engine and gearbox. Below is a compatibility table for the main modifications:
| Engine | Gearbox type | Left support (art. no.) | Right support (article) | Rear support (art. no.) |
|---|---|---|---|---|
QR25DE (2.5 petrol) |
Manual transmission / automatic transmission | 11220-4M000 | 11220-4M010 | 11220-4M020 |
MR20DE (2.0 petrol) |
Manual transmission / CVT | 11220-JD000 | 11220-JD010 | 11220-JD020 |
M9R (2.0 diesel) |
Manual transmission | 11220-4M500 | 11220-4M510 | 11220-4M520 |
Original supports from Nissan They last longer, but their price can exceed 10 thousand rubles per set. Alternative brands with a good reputation:
- 🔧 Febi (Germany) - optimal price/quality ratio, article numbers coincide with the original ones.
- 🔧 Sidem (Belgium) - soft rubber compounds, suitable for cold climates.
- 🔧 Corteco - a budget option, but the resource is 20–30% lower.
When choosing, pay attention to bushing material: Cheap analogues often use plastic instead of metal, which leads to rapid wear. For diesel versions X-Trail T31 supports with hydraulic dampers — they dampen vibrations better at low speeds.
When purchasing supports, check the package contents: original kits often come with new bolts and washers. Using old fasteners can lead to play!
Step-by-step instructions for replacing engine mounts Nissan X-Trail T31
Replacing supports is a labor-intensive process that requires a lift or inspection pit. If you have little experience, it is better to entrust the work to a service, but if you have the tools and an assistant, you can do it yourself. Let's look at the process using an example right support (the algorithm for the left and back is similar, but with nuances).
Required tools:
- 🔧 Set of heads and socket wrenches (10–17 mm).
- 🔧 Jack and engine stand (or wooden block).
- 🔧 WD-40 or a similar composition for unscrewing stuck bolts.
- 🔧 Mount or crowbar for lifting the engine.
Work order:
- Disconnect the battery by removing the negative terminal.
- Place a jack under the engine pan (use a wooden spacer to avoid damaging the metal). Raise the motor 1–2 cm to remove the load from the mount.
- Unscrew the bolts securing the support to the body and engine (usually 3-4 bolts of 14 mm). For rusty connections, use WD-40 and allow time to dry.
- Remove the old support and compare it with the new one - check the alignment of the holes and the shape of the rubber damper.
- Install a new support by tightening the bolts crosswise with a force of 50–60 Nm. Lower the jack and check for play.
For replacement rear support You will need to remove the air filter and partially dismantle the protection. On CVT versions X-Trail T31 the rear support is often attached to the box - here it is important not to overtighten the bolts so as not to deform the body JF011E.
⚠️ Attention: After replacing the supports, be sure to check engine tilt angle. If the motor is installed crookedly, this will lead to premature wear of the new mountings and problems with the drive shafts. Use a level or refer to factory marks.
What to do if the support bolts are stuck?
If the bolts do not come out, try the following:
1. Heat the mount with a hair dryer (do not overheat the rubber elements!).
2. Use an impact wrench or a socket wrench with a lever.
3. As a last resort, cut the bolt with a grinder, but be careful not to damage the threads in the body.
Common mistakes when replacing supports and how to avoid them
Even experienced craftsmen sometimes make mistakes that shorten the service life of new supports. Here are the most common mistakes and ways to prevent them:
- 🔧 Incorrect bolt tightening: Overtightened fasteners deform the rubber damper, and loose tightening leads to play. Use a torque wrench with a torque of 50–60 Nm.
- 🔧 Ignoring rear support: Many people change only the side airbags, forgetting about the back one. This leads to imbalance and accelerated wear of the remaining supports.
- 🔧 Saving on a jack: Lifting the engine from only one side (for example, the right) may cause misalignment. Always use a stand or second jack to distribute the load evenly.
- 🔧 Installation of used supports: Rubber “agees” over time, even if it looks intact on the outside. Buy only new parts.
Another common mistake is failure to check the alignment of the engine and gearbox after replacement. On X-Trail T31 with a variator this is fraught with belt slipping and errors P17F0 or P17F1 (primary/secondary pulley misalignment). To avoid problems after installing new supports:
- Start the engine and let it idle for 5-10 minutes.
- Check for smooth gear shifting (for automatic transmission/variator) or absence of jerking when starting (for manual transmission).
- Visually inspect the supports to ensure that the rubber is compressed evenly.
After replacing the supports, be sure to reset the CVT adaptations (if any) through the diagnostic scanner. This will help the box “get used” to the new engine position.
Engine mount replacement cost: 2026 prices
The price of work and spare parts varies depending on the region and type of service station. Below is the approximate price for Nissan X-Trail T31:
| Service/Spare part | Price (RUB) | Notes |
|---|---|---|
| Original support (1 pc.) | 3 500–6 000 | The price depends on the side (the back is more expensive) |
| Analogue (Febi/Sidem) | 2 000–4 000 | Resource is 10–20% lower than the original |
| Replacing one support (work) | 1 500–3 000 | Without removing protection or additional work |
| Replacing the set (3 supports) | 8 000–15 000 | Includes diagnostics and adjustments |
You can save money by purchasing spare parts yourself (for example, through Exist.ru or Autodoc) and agreeing with the service only about work. However, be careful with cheap analogues - some supports (especially those made in China) become dull after 20–30 thousand km, which leads to repeated replacement.
For owners X-Trail T31 with a mileage of 200 thousand km, it is advisable to replace the supports set, even if visually some of them look intact. Rubber loses elasticity with age, and “fresh” cushions will last longer under uniform load.
FAQ: Frequently asked questions about engine mounts Nissan X-Trail T31
Is it possible to drive with worn out mounts?
In the short term, yes, but it is fraught with consequences. On X-Trail T31 with a variator, worn bearings lead to belt slippage and overheating of the box. On a manual transmission there may be problems with shifting gears. The maximum “safe” mileage with defective airbags is up to 1,000 km, after which the risk of transmission damage increases sharply.
How long does it take to replace supports?
In the service, it takes 1–1.5 hours to replace one support, and 3–4 hours to replace a set. When working independently without experience, allow 5–6 hours (taking into account possible difficulties with rusty bolts). The rear support takes longer to replace due to the need to remove the air filter.
Which supports fail most often? X-Trail T31?
On petrol versions (QR25DE, MR20DE) is usually the first to “die” right support — it takes on the main load during overclocking. On diesels (M9R) wears out more often rear support due to high torque. If the car is operated with a trailer, the service life of all airbags is reduced by 30–40%.
Is it necessary to do a wheel alignment after replacing the bearings?
No, replacing the supports does not affect the wheel alignment angles. However, if suspension elements (for example, levers) were removed during dismantling/installation, then a wheel alignment is required. Also check alignment of engine and gearbox — if the supports are installed incorrectly, it may be necessary to adjust the position of the power unit.
Is it possible to restore old supports?
Theoretically, yes, some workshops offer rubber vulcanization or replacing the damper. However, such repairs are unreliable: the restored supports last no more than 10–15 thousand km, and their rigidity often exceeds factory standards, which leads to increased vibrations. For X-Trail T31 this is an unjustified risk, especially if the car is operated in difficult conditions.
