Rear trailing arm in suspension Nissan X-Trail T31 experiences enormous loads, and its silent blocks are one of the first parts to fail after 100-120 thousand kilometers. Worn rubber-to-metal joints are manifested by knocking noises in the rear of the body, the car pulling away when braking, and uneven tire wear. Car service centers charge from 6 to 12 thousand rubles per side for replacement, but if you have the tools and patience, you can perform the procedure yourself.
This article contains a detailed analysis of the replacement process, taking into account T31 design specifics, a list of necessary tools (including non-obvious devices), as well as typical errors that lead to premature failure of new silent blocks. We will consider both repair options: with and without removing the lever, and also give recommendations on the selection of spare parts among original ones and analogues from Febi, TRW And Sasic.
Signs of wear on rear arm silent blocks
The first symptoms of problems with silent blocks are often confused with faulty shock absorbers or wheel bearings. However, there are a number unique features, which directly point to rubber-metal hinges:
- 🔊 Knocking or clicking noises when driving over bumps at low speed (especially noticeable during a cold start). The sound comes from the rear axle area and becomes louder when the body is loaded (for example, when someone sits in the back seat).
- 🚗 Pulling the car to the side during sudden braking or acceleration. This occurs due to play in the silent blocks, which disrupts the suspension geometry.
- 🔄 Uneven rear tire wear along the inner or outer edge. Worn silent blocks change the wheel alignment angles, which leads to “eating” of the rubber.
- 🛑 Vibrations on the steering wheel when driving on a flat road at a speed of 80-100 km/h. Often accompanied by a feeling that the rear of the car is “driving.”
For an accurate diagnosis, a visual examination is sufficient. Jack up the rear X-Trail T31, rest the pry bar against the lever and try to move it up and down. Play of more than 1-2 mm or cracks in the rubber of the silent block is a direct signal for replacement. Please note: T31 wears frequently front silent block of the lever (from the body side), since it takes on the main load during braking.
⚠️ Attention: If you ignore the wear of silent blocks, this will lead to deformation of the seats in the lever and body. In advanced cases, it is necessary to replace the entire lever or weld repair bushings, which costs 3-5 times more than timely replacement of hinges.
Which silent blocks to choose: original vs analogues
For Nissan X-Trail T31 (2007-2013) original silent blocks of the rear trailing arm go under the article numbers:
- 54501-4M00A — front silent block (from the body side)
- 54501-AL50A — rear silent block (from the hub)
The cost of original parts is from 2,500 to 3,800 rubles per piece. However, there are worthy analogues on the market that are not inferior in terms of resource, but cost 1.5-2 times cheaper:
| Brand | Article | Price (per piece), ₽ | Features |
|---|---|---|---|
| Febi | 22621 | 1 200–1 500 | High-quality rubber, but requires lubrication during installation |
| TRW | JBU1044 | 1 800–2 200 | Reinforced design, suitable for harsh environments |
| Sasic | 2005040 | 900–1 100 | Budget option, resource ~80 thousand km |
| Nissens | 85-01-213 | 1 400–1 700 | Optimal price/quality ratio, soft tires |
When choosing analogues, pay attention to bushing material: for cheap silent blocks it is often made of low-quality metal, which is deformed when pressed. Also check availability protective boots — without them, rubber quickly deteriorates from dirt and moisture. For T31 with a mileage of more than 150 thousand km, we recommend installing TRW or Febi — their rubber is less susceptible to “drying out” over time.

Necessary tools and preparation for work
To replace the rear arm silent blocks with X-Trail T31 you will need a specialized tool. Without it, you risk damaging the seats or new parts. Here is the complete list:
- 🔧 Silent block remover (preferably hydraulic or screw with stops). Suitable for universal Force or Jonnesway.
- 🔨 Hammer and mandrels for pressing (the diameter must match the external size of the silent block).
- 🔩 Socket heads by 17, 19 and 22 mm (for the lever and stabilizer bolts).
- 🔧 Torque wrench (tightening torque of the lever bolts is 100–120 Nm).
- 🛠️ WD-40 or similar cleaner for treating rusty joints.
- 🔥 Gas burner (optional if the silent block is “stuck” to the lever).
Before starting work, complete the following steps:
- Place the car on a level surface and secure the front wheels with chocks.
- Loosen the rear wheel mounting bolts on the replacement side.
- Jack up the rear end and place safety stands under the side members.
- Remove the wheel and disconnect the brake caliper (hang it on a wire to avoid damaging the hose).

Key point: on X-Trail T31 the rear trailing arm is attached to the body two bolts (one front, one rear), and to the hub - with one bolt with an eccentric sleeve. The eccentric is responsible for adjusting the camber of the rear wheels - during reassembly, its position cannot be changed without subsequent testing on a bench! If you do not plan to do a wheel alignment, mark the position of the eccentric with a marker before disassembling.
Step-by-step instructions for replacing silent blocks
There are two replacement methods: with and without removing the lever. The first method is easier for beginners, the second is faster, but requires skill. We will consider both options.
Method 1: With lever removal (recommended for first replacement)
- Unscrew the lever mounting bolts:
- Front silent block bolt (to the body) - 19 mm head.
- Rear silent block bolt (to the body) - 17 mm head.
- The bolt for fastening to the hub (with an eccentric) is a 22 mm head.
When unscrewing the body bolts, hold the nuts on the back side with a wrench to avoid turning.
Before pressing out, apply anti-corrosion lubricant to the lever seat (for example, Liqui Moly Kupfer-Spray). This will make it easier to install new parts.
Method 2: Without removing the lever (for experienced ones)
This method saves time but requires special puller with elongated legs. Procedure:
- Loosen the lever mounting bolts, but do not remove them completely.
- Install the puller on the front silent block and press it through the opening in the lever.
- Press the new silent block into place using a mandrel and a hammer. Make sure it's seated all the way.
- Repeat the procedure for the rear silent block.
- Tighten all bolts to the required torque (100–120 Nm).
The advantage of this method is that there is no need to adjust the camber, since the lever remains in place. However, without a puller, there is a high risk of damaging the seats in the body.
What to do if the silent block does not press out?
If the silent block is “stuck” to the lever, use a gas burner to locally heat the seat (do not overheat the rubber!). An alternative is to drill out the inner bushing and use a chisel to split the remaining rubber. In extreme cases, the lever will have to be replaced entirely (original article number - 54501-4M000).
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when replacing silent blocks with X-Trail T31. Here are the most common ones and how to prevent them:
- 🔧 Distortion during pressing: if the silent block is installed crookedly, it will last no more than 20 thousand km. Always use a mandrel whose diameter is equal to the outer diameter of the joint.
- 🔩 Tightening bolts by weight: This leads to rubber deformation and rapid wear. Tighten the body bolts only after the vehicle is lowered onto its wheels.
- 🛠️ Ignoring the eccentric: changing the position of the eccentric bolt disrupts the camber. Always mark its original position!
- 🚫 Lack of lubrication: new silent blocks (especially Febi And Sasic) require treatment with soapy water or a special lubricant for rubber-metal products before installation.
⚠️ Attention: On T31 with system 4WD after replacing the silent blocks, be sure to check the condition of the ball joints of the rear suspension (part number 40520-4M000). Worn ball joints accelerate the destruction of new silent blocks due to increased dynamic loads.
Another common problem is seat corrosion in the lever. If you find rust, clean it with a wire brush and treat it with a converter (for example, Tsinkar). In advanced cases, it may be necessary to bore holes for repair bushings.
When does the entire lever need to be replaced?
In some cases, replacing silent blocks is impractical, and installation of a new lever is required. Here are signs to consider this option:
- 🔧 Deformation of seats: if the holes for the silent blocks become oval or have cracks, the new hinges will not last long.
- 💥 Damage to welds: on T31, the arms often rust where the stabilizer is attached. If the seam is broken, the lever may burst under stress.
- 🔄 Multiple replacements of silent blocks: If you have already changed the hinges 2-3 times, it is more economical to install a new lever with pre-pressed silent blocks.
Original rear trailing arm for X-Trail T31 goes under the article 54501-4M000 (left) and 54501-4M001 (right). Cost - from 8,000 to 12,000 rubles. Among analogues, levers from Febi (item 22620) and TRW (JBU1043), which come with silent blocks already installed.
When replacing the entire lever, be sure to check:
- Condition stabilizer bushings (article 54520-4M000).
- Backlash in ball joint (if there is one, replace it along with the lever).
- Integrity shock absorber boots - their damage will accelerate the wear of new parts.
Wheel alignment after replacement: is it necessary?
On Nissan X-Trail T31 the rear suspension has adjustable camber, which is adjusted by an eccentric bolt on the lever. If you:
- 🔧 We didn’t touch the eccentric and tightened it in its original position - wheel alignment is not necessary.
- 🔄 Changed the position of the eccentric or replaced the entire lever - Camber adjustment is required.
You can check the wheel alignment angles yourself using:
- Laser level gauge (error up to ±0.5°).
- Special template for measuring camber (sold in car dealerships).
- Mobile stand (many tire shops offer an “express check” service for 500–800 rubles).
Valid values for X-Trail T31:
- Camber: -1° ± 30' (for 4WD) or -1° ± 45' (for 2WD).
- Toe: 0° ± 10' (adjustable by rear suspension links).
⚠️ Attention: If after replacing the silent blocks the car pulls to the side and the camber is normal, check tire pressure And condition of rear brake pads. Uneven pad wear can mimic suspension problems.
Even if you have not changed the position of the eccentric, after replacing the silent blocks, it is recommended to check the camber after 500–1000 km. The rubber of the new hinges may “shrink”, which will affect the wheel alignment angles.
FAQ: Frequently asked questions about replacing silent blocks
Is it possible to drive with worn rear arm bushings?
Short-term (up to 1-2 weeks) - yes, but this will lead to:
- Accelerated tire wear (up to 30% reduction in service life).
- Damage to seats in the lever and body.
- Deterioration of controllability at high speeds.
On X-Trail T31 It is forbidden to drive off-road with worn silent blocks - this can lead to deformation of the lever.
How often do you need to change silent blocks on the X-Trail T31?
Service life depends on operating conditions:
- City mode: 120–150 thousand km.
- Mixed mode (city + highway): 100–120 thousand km.
- Aggressive riding/off-road: 60–80 thousand km.
Signs of wear (knocks, slips) may appear earlier - especially if the car is often operated with overload.
Is it possible to replace silent blocks without a puller?
Theoretically yes, but:
- The risk of damage to seats is 70%.
- The operating time will increase by 2–3 times.
- Without a mandrel, the new silent block will sit crookedly.
An alternative is to use vice And set of spacers, but this is only suitable for experienced craftsmen.
What happens if you don't tighten the lever mounting bolts?
Consequences:
- Play in the suspension, knocking noises when driving.
- Accelerated wear of silent blocks (2-3 times faster).
- Risk of bolts unscrewing while driving.
Body bolts necessarily tighten with a torque of 100–120 Nm with the car lowered!
What lubricant should I use when installing silent blocks?
Recommended options:
- Soap solution (10% liquid soap + water) - to facilitate pressing.
- Lubricant for rubber-metal products (For example, Liqui Moly Gummi-Pflege).
- Silicone grease (not aggressive to rubber).
Prohibited use Litol, grease or graphite lubricant — they destroy rubber!
