Rear silent blocks on Nissan Qashqai J11 (2013–2021) is one of those suspension elements that are often left unattended until they begin to “remind” themselves through knocks, squeaks or deterioration in handling. These rubber-metal joints are responsible for dampening vibrations and ensuring the correct geometry of the rear multi-link suspension, but over time their elastic layer is destroyed under the influence of loads, temperatures and aggressive reagents. Unlike the front silent blocks, the rear ones are Qashqai J11 They wear out less often, but their replacement requires precision - installation errors can lead to premature failure of new parts or even damage to the levers.

In this article we will analyze signs of wear on rear silent blocks, let's look in detail at selection of original and analog spare parts (with article numbers and prices), and we will also give step-by-step instructions for replacement - from preparing tools to final tightening of bolts. We will pay special attention typical errors during replacement, which reduce the service life of new silent blocks by 30–50%. If you are planning repairs yourself or just want to control the work of a service station, this material will help you avoid unnecessary expenses and unpleasant surprises.

Signs of wear on the rear silent blocks Nissan Qashqai J11

Rear suspension silent blocks rarely “die” suddenly - their wear appears gradually, and in the early stages the symptoms can be confused with faulty shock absorbers or wheel bearings. However there are several characteristic features, which directly indicate problems with rubber-metal joints:

  • 🔊 Knocks or clicks in the rear of the car when driving over uneven surfaces (especially noticeable on small bumps or speed bumps). The sound often sounds like metal hitting metal.
  • 🚗 Pulling the car to the side when driving in a straight line, even if the wheel alignment has been done recently. This occurs due to changes in wheel alignment angles.
  • 🔄 Uneven rear tire wear - especially along the inner or outer edge. Often accompanied by a “sawtooth” tread pattern.
  • 🛑 Deterioration in directional stability at high speeds (the car “scours” along the road and requires constant steering).
  • 💨 Creaks when turning the steering wheel in place or at low speeds - a sign of friction between rubber and metal due to the destruction of the silent block.

It is important to consider that other malfunctions can cause similar symptoms: for example, wear of stabilizer bushings or play in ball joints. To accurately diagnose the problem, a visual inspection is needed. Jack up the rear of the car and inspect the silent blocks for:

  • 🔍 Cracks or tears in rubber (even minor damage is a reason for replacement).
  • 💥 Squeezing rubber out from under metal bushings (a sign of critical wear).
  • 🔧 Play between bushing and lever (checked with a pry bar or by hand while rocking the lever).
⚠️ Attention: On Qashqai J11 With a mileage of more than 100 thousand km, “hidden” wear of silent blocks is often encountered - when outwardly the rubber looks intact, but inside it has delaminated. Such a defect is revealed only when the lever is dismantled.

📊 How often do you check the condition of your car's suspension?
  • Once every 10–20 thousand km
  • Only when knocking occurs
  • Before the seasonal tire change
  • Never checked

Original and similar spare parts: articles, prices, what to choose

On Nissan Qashqai J11 (including restyled versions 2017–2021) two types of rear silent blocks are installed:

  1. Silent blocks of trailing arms (2 pcs per side) - article number 54501-JM00A (left/right).
  2. Cross arm silent blocks - article number 54503-JM00A (also paired).

Original spare parts from Nissan will cost RUB 2,500–3,800 per piece (depending on dealer). However, many owners prefer analogues, which are often not inferior in quality, but are cheaper. The table below shows verified brands and their articles:

Brand Article Silent block type Price (per piece), rub. Features
Nissan (original) 54501-JM00A Trailing arm 3 200–3 800 Guaranteed compatibility, long service life
Febi 23940 Trailing arm 1 800–2 200 Good quality rubber, often used in service stations
Lemforder 33506 01 wishbone 2 100–2 500 Reinforced design, suitable for aggressive riding
Sasic 2005450 Set (4 pcs.) 4 500–5 200 Budget option, but the tires are stiffer than the original
TRW JTC1342 Trailing arm 2 300–2 700 High quality, often recommended by craftsmen

When choosing analogues, pay attention to:

  • 🔹 Rubber material - with cheap silent blocks it often hardens in the cold or crumbles when heated.
  • 🔹 Availability of lubrication - some brands (for example, Lemforder) deliver parts with factory lubricant, which simplifies installation.
  • 🔹 Bushing geometry — even a slight deviation in size can lead to play after pressing.

💡

Before purchasing, check whether silent blocks are sold as a set (for example, Sasic 2005450). It's cheaper than buying parts individually, even if you only need to replace one side.

Tools and preparation for replacement: what you will need

Replacing rear silent blocks with Qashqai J11 - a task of average complexity, but it won’t be possible without a special tool. Here minimum setwhich will be required:

  • 🔧 Jack and stops (or a lift if there is access).
  • 🔨 Silent block remover (For example, JTC 4439 or similar). Without it, pressing out the old part may damage the lever.
  • 🔩 Socket heads at 17, 19 and 21 mm (for lever bolts).
  • 🔧 Torque wrench (required for proper tightening!).
  • 🧴 Penetrating lubricant (For example, WD-40 or Liqui Moly MoS2).
  • 🛠️ Hammer and mandrel (for pressing in new silent blocks).
  • 🔥 Gas burner or hair dryer (helps soften the rubber during dismantling).

Also prepare:

  • 📋 New bolts and nuts (it is recommended to replace, as the old ones may be deformed). Article number of original bolts - 08922-64010.
  • 🧤 Protective gloves (rubber of silent blocks can be toxic).
  • 📸 Photo recording - take a photo of the location of the bolts and levers before disassembling so as not to confuse them during reassembly.

⚠️ Attention: If you do not have a puller for silent blocks, do not try to knock them out with a hammer “by eye” - this almost always leads to deformation of the lever. As a last resort, you can use improvised means (for example, a long bolt with a nut and washers), but the risk of damaging the part remains.

Step-by-step instructions for replacing rear silent blocks

The replacement process is the same for both sides, so let's look at it using the example of one wheel. Important: It is better to carry out work on a lift or inspection hole, but if there are none, use a jack with reliable stops.

Step 1. Wheel removal and preparation

  • Loosen the wheel bolts while the car is on the ground.
  • Lift the rear of the car and remove the wheel.
  • Clean the lever mounting bolts from dirt (use a wire brush and lubricant).

Step 2: Removing the Lever

  • Unscrew the bolt securing the lever to the subframe (usually 19 or 21 mm).
  • Disconnect the arm from the hub assembly (a ball joint puller may be required).
  • Carefully lower the lever down without damaging the brake hoses or ABS sensors.

Step 3. Pressing out old silent blocks

  • Clamp the lever in a vice (using soft pads to avoid damaging the paint).
  • Use a puller to push out the old silent block. If it gets stuck, heat it with a hairdryer or torch (but do not overheat - the rubber may catch fire!).
  • Clean the seat from rust and rubber residues.

Step 4. Installation of new silent blocks

  • Lubricate the seat and outer surface of the new silent block with soapy water or special lubricant (for example, Liqui Moly Silberfett).
  • Carefully press the part with a puller or mandrel, making sure that it sits evenly, without distortion.
  • Check that the rubber is not twisted - this will shorten its service life.

Step 5. Assembly and tightening

  • Reinstall the lever and screw in the new bolts (do not fully tighten them!).
  • Lower the car onto its wheels and only after that tighten the bolts with a torque wrench 80–100 Nm (for trailing arms) and 60–80 Nm (for transverse ones).
  • Check the wheel alignment angles (it is advisable to do a wheel alignment after replacement).

What happens if you undertighten or overtighten the bolts?

Loose bolts lead to play in the silent blocks, which accelerates their wear and can cause vibrations at speed. The reupholstery deforms the rubber layer, which is why the silent block loses its elasticity and cracks after 10–15 thousand km. This is especially critical for Qashqai J11 with multi-link suspension where the geometry must be precise.

Typical replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes, which then cost the owners repeated repairs. Here the most common mistakes and ways to prevent them:

  • 🔧 Reusing old bolts - they stretch when tightened and do not provide the required force. Always take new ones!
  • 🔥 Overheating of the silent block during dismantling — if you heat it with a burner for too long, the rubber melts and sticks to the lever. Maximum - 1-2 minutes of heating.
  • 🛑 Tightening bolts by weight - this leads to distortion of the silent block. Tighten only after the machine is on its wheels.
  • 🧴 Lack of lubrication during installation — without it, the rubber may tear when pressed. Use soap solution or special paste.
  • 🔄 Incorrect tightening torque - “by eye” almost always means either under-tightening or over-tightening.

💡

The most critical mistake is ignoring the wheel alignment after replacement. On Qashqai J11 Even a slight change in wheel alignment angles leads to accelerated tire wear and deterioration in handling.

One more nuance - choice between rubber and polyurethane silent blocks. The latter last longer and are more resistant to aggressive environments, but:

  • ✅ Advantages of polyurethane: service life is 2–3 times longer, is not afraid of oils and reagents.
  • ❌ Cons: more expensive (from 4,000 rubles per piece), more rigid (comfort may deteriorate), require precise installation.

For most owners Qashqai J11 the optimal choice is high-quality rubber analogues (Lemforder or TRW). Polyurethane is only suitable for cars with an aggressive driving style or frequent off-road driving.

Service life and prevention: how to extend the life of silent blocks

On average, rear silent blocks are Nissan Qashqai J11 serve 80–120 thousand km, but this indicator strongly depends on operating conditions. To delay replacement as much as possible, follow these simple recommendations:

  • 🚿 Wash your pendant in winter - salt and reagents destroy rubber. It is enough to wash the wheel arches under pressure once every 2 weeks.
  • 🛣️ Avoid sharp impacts — driving speed bumps or getting into potholes reduces service life by 30–40%.
  • 🔧 Check the fastenings — once every 10 thousand km, check the tightness of the bolts of the levers (they may loosen over time).
  • 🌡️ Control the temperature — if silent blocks constantly overheat (for example, due to a closely located exhaust system), their rubber becomes tanned.

Also note quality of roads — if you often drive on primers or crushed stone, the silent blocks wear out 1.5–2 times faster. In such circumstances it makes sense:

  • 🔹Install protective boots on levers (for example, from Febi or Corteco).
  • 🔹Use lubricant for silent blocks (For example, CRC Rubber Grease) at each maintenance.
  • 🔹Check often play in suspension (once every 5 thousand km).

💡

If you frequently carry heavy loads or tow a trailer, the rear suspension bushings will wear out 20-30% faster. In this case, replace them with reinforced ones (for example, Lemforder with article number 33506 01).

When to contact a service station, and when you can handle it yourself

Replacing rear silent blocks with Qashqai J11 - a task that most car owners can handle with a minimum set of tools. However, there are situations when It's better to trust the professionals:

  • 🔧 Puller missing — without it there is a high risk of damaging the lever.
  • 🔩 The bolts are stuck - if they do not unscrew even after heating, they can be torn off, which will entail replacing the lever.
  • 📏 Needs wheel alignment adjustment — after replacement, the corners must be checked, and this requires special equipment.
  • 🚗 The suspension is heavily corroded - on machines older than 5 years, bolts and levers may be covered with rust, which complicates the work.

If you decide to change the silent blocks yourself, keep in mind:

  • ⏱️ Time — one side takes 2–3 hours (without experience).
  • 💰 Savings — independent replacement costs 3–4 times less than at a service station (where work costs from 3,000 rubles per side).
  • 🔧 Tool - if you don’t have a torque wrench or puller, you can rent them (many auto tool stores provide this service).

💡

If you have never repaired a suspension, practice removing and installing the lever without replacing the silent blocks. This will help you understand the design and avoid mistakes during real work.

FAQ: Frequently asked questions about rear silent blocks Nissan Qashqai J11

Is it possible to drive with worn silent blocks?

Short term - yes, but it is dangerous. Worn silent blocks lead to:

  • 🔹 Loss of controllability (especially at high speeds).
  • 🔹 Accelerated wear of tires and other suspension elements.
  • 🔹 Risk of the lever coming off under heavy loads (for example, when falling into a hole).

If you notice signs of wear, replace parts within 1-2 weeks.

How much does a replacement cost at a service station?

The cost of work depends on the region and level of service:

  • 🔹 Replacing silent blocks on one side - 2,500–4,000 rub.
  • 🔹 Comprehensive replacement (all 4 silent blocks) - 6,000–10,000 rub.
  • 🔹 Additionally, you may need to pay for wheel alignment (1,500–2,500 rub.).

In total, with spare parts, the repair will cost 10,000–20,000 rub. (depending on the choice of parts).

Which silent blocks are better - original or analogues?

Original parts from Nissan are guaranteed to fit and last a long time, but their high price (from 3,000 rubles per piece) is often unjustified. High-quality analogues (Lemforder, TRW, Febi) are no worse, and sometimes even surpass the original in terms of resource. The main thing is to avoid cheap no-name brands (for example, "AvtoVAZ" or unknown Chinese manufacturers).

Do I need to change silent blocks in pairs?

Not required, but recommended. If the silent blocks are worn out on one side, then on the other they are most likely also close to replacement (wear occurs relatively evenly). Replacing in pairs will save time and money in the long run.

Is it possible to restore silent blocks?

No, this is a one-time use item. Some “masters” suggest pouring sealant or epoxy resin into the cracks, but this is a temporary solution that will not restore the elasticity of the rubber. Such silent blocks will last 1–2 thousand km at most.
