ŠKODA Rapid 2018 front control arm silent blocks: when to change, which ones to choose and how to replace

Silent blocks of the front levers on ŠKODA Rapid 2018 is one of those details that often goes unnoticed until it starts causing serious problems. These rubber-to-metal joints dampen vibrations and provide a smooth ride, but over time they lose elasticity, which leads to knocking, poor handling and even uneven tire wear. Unlike many European competitors, Rapid on the platform MQB A0 has a specific suspension design, where silent blocks are integrated into the levers in a non-standard way - this complicates their replacement and requires a special approach.

If you notice that the car has become worse in handling the road on uneven surfaces, and when passing speed bumps you hear dull impacts from the front - most likely, they are to blame. In this article we will look at how diagnose wear, what silent block brands suitable for Rapid 2018, and is it possible to replace them yourself without a specialized tool. We will also reveal design feature of the front levers on this model: the original silent blocks are not sold separately from the levers, but there are workarounds.

Signs of wear on silent blocks: when is it time to go for diagnostics

The first symptoms of a malfunction of the silent blocks of the front levers on ŠKODA Rapid often confused with shock absorber or ball joint problems. However, there are characteristic signs that will help to accurately identify the source of the problem:

• 🔊 Knocking or squeaking when driving over uneven surfaces (especially noticeable on small bumps or asphalt joints). The sound usually comes from the front and gets louder as the suspension is loaded.
• 🚗 Deterioration in handling: the car begins to “float” in the lane, reacts worse to steering wheel turns, especially at high speeds.
• 🔄 Uneven tire wear (usually the inner or outer edge). This occurs due to changes in the wheel alignment angles that the silent blocks help maintain.
• 🛑 Vibrations on the steering wheel when braking or accelerating - a sign that the rubber insert of the silent block has delaminated and has ceased to dampen vibrations.

On Rapid In 2018, wear of the silent blocks appears earlier than on later models due to the characteristics of the material of the rubber inserts. On average, their resource is 80–100 thousand km, but when driving on bad roads or an aggressive driving style, it can be reduced to 60 thousand km. The critical moment is when the rubber starts peel off from the metal sleeve, which is visible upon visual inspection (cracks, tears or displacement of the sleeve relative to the center).

⚠️ Attention: If you ignore the wear of silent blocks, this will lead to play in the suspension, which in turn will accelerate the destruction of ball joints and wheel bearings. On ŠKODA Rapid This is also fraught with a violation of the geometry of the body during strong impacts.

Which silent blocks are suitable for ŠKODA Rapid 2018: comparison of brands

The main problem when choosing silent blocks for Rapid — lack of original spare parts on separate sale. The manufacturer supplies them only assembled with levers (article no. 6Q0407151 for left and 6Q0407152 for the right one), which makes replacement expensive. However, there are alternative solutions:

Brand	Article	Type	Average price (per 1 piece)	Features
Original VAG	6Q0407151/152	Lever assembly	8 000–12 000 ₽	Guaranteed quality, but high cost. Suitable for Rapid, Polo and VW Golf on the MQB platform.
Lemförder	34147 01	Separate silent block	1 200–1 800 ₽	A popular analogue, but requires pressing. The rubber is softer than the original, which may shorten the service life.
Febi	34147	Separate silent block	900–1 500 ₽	A budget option, but there are defective batches with uneven rubber vulcanization.
TRW	JTC1471	Lever assembly	6 500–9 000 ₽	The quality is close to the original, but cheaper. Suitable for severe operating conditions.
Sasic	2005010	Polyurethane	2 500–3 500 ₽	More durable than rubber ones, but transmit more vibrations to the body. Requires precise installation.

If you decide to save money and install separate silent blocks (for example, Lemförder or Febi), please note that replacing them will require special puller and press. It is difficult to do this in a garage - metal bushings often “stick” to the lever, and without a hydraulic press they cannot be pressed out. An alternative is to purchase lever assemblies from TRW or Meyle, which are cheaper than the original ones, but have comparable quality.

They stand apart polyurethane silent blocks (for example, from Sasic or Powerflex). They last 2–3 times longer than rubber ones, but have disadvantages:

• ⚙️ They transmit more vibrations to the steering wheel and body (especially noticeable on bumps).
• 🔧 They require ideal geometry of the levers during installation - the slightest misalignment will lead to accelerated wear.
• 💰 They cost 2–3 times more than their rubber counterparts, but pay for themselves with a mileage of over 150 thousand km.

Is it possible to replace silent blocks yourself: step-by-step instructions

Replacing silent blocks with ŠKODA Rapid 2018 is a task of average complexity, but without experience and tools it is better to entrust it to professionals. If you decide to do it yourself, follow the algorithm:

1. Preparation: drive the car onto a pit or a lift, fix the rear wheels, loosen (but do not remove!) the nuts securing the arms.
2. Removing the lever: Unscrew the bolts securing the lever to the subframe (you will need an 18mm socket and an extension), then disconnect the ball joint from the steering knuckle.
3. Pressing out old silent blocks: You can't do without a puller here. If it is not there, you can try to knock out the bushings with a hammer through the mandrel, but the risk of damaging the lever is high.
4. Installing new ones: new silent blocks are pressed in using a press or vice. It is important to ensure that they stand up straight, without distortion.
5. Assembly: install the lever in place, tighten the bolts firmly 100–120 Nm (for Rapid this is critical - weak tightening will lead to backlash).

Socket set (13, 16, 18 mm)

Puller for silent blocks or press

Torque wrench (required!)

Penetrating lubricant (eg. WD-40 or Liqui Moly MoS2>)

New bolts for securing the arms (it is recommended to replace them, as the old ones get tired) -->

The main difficulty is correct pressing. If the silent block is installed crookedly, it will last much less. It is also important not to overtighten the lever mounting bolts - this can deform the rubber insert. On Rapid 2018, the tightening torque for the front control arm bolts is 100 Nm + 90° (first tighten to 100 Nm, then tighten 90 degrees).

⚠️ Attention: After replacing silent blocks necessarily do a wheel alignment. Even if you have the parts perfectly level, the suspension geometry will still change and without adjustment the tires will wear unevenly.

What happens if you don't do a wheel alignment?

Without adjusting the wheel alignment angles after replacing the silent blocks, you will receive:

- Accelerated wear of tires (in 5–10 thousand km the tread can “eat” to the cord).

- The car pulls to the side when driving in a straight line (especially noticeable at speeds above 80 km/h).

- Increased load on wheel bearings and ball joints, which will reduce their service life by 30–40%.

How much does a replacement cost: prices in services and savings when repairing yourself

The cost of replacing the front control arm silent blocks with ŠKODA Rapid 2018 depends on whether you install the control arms as a whole or individual bushings. Let's consider both options:

Replacement option	Cost of spare parts (2 pcs.)	Cost of work in the service	Total
Original lever assemblies	16 000–24 000 ₽	3 000–5 000 ₽	19 000–29 000 ₽
Analogs of levers (TRW, Meyle)	12 000–18 000 ₽	3 000–5 000 ₽	15 000–23 000 ₽
Separate silent blocks (Lemförder, Febi)	2 400–3 600 ₽	4,000–7,000 rubles (due to the complexity of pressing)	6 400–10 600 ₽
Polyurethane silent blocks (Sasic)	5 000–7 000 ₽	4 000–7 000 ₽	9 000–14 000 ₽

As can be seen from the table, the most budget option - separate rubber silent blocks, but saving on spare parts will result in a higher cost of work. If you do not have experience in pressing, it is better to choose assembled levers - this will save time and nerves. On average in Russia, replacing both front arms with silent blocks costs 15 000–25 000 ₽, depending on the region and level of service.

You can save money if:

• 🔧 Buy assembled levers from TRW or Meyle - they are 20–30% cheaper than the original, but are not inferior in quality.
• 🛠️ Find a service that has a promotion on suspension replacement (sometimes they offer a discount of up to 20% for complex repairs).
• 🔄 Replace silent blocks at the same time as ball joints or wheel bearings - this will reduce the overall cost of work.

💡

If your mileage has exceeded 100 thousand km, it makes sense to consider replacing the lever assemblies, even if the silent blocks have not yet “died”. This will prevent other suspension components from wearing out quickly and save money in the long run.

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when working with silent blocks ŠKODA Rapid. Here are the most common ones and how to prevent them:

1. Incorrect pressing: if the silent block is installed crookedly, it will last no more than 10–15 thousand km. To avoid this, use mandrels (can be made from old bushings) and press the part strictly perpendicular to the plane of the lever.
2. Using old bolts: The bolts securing the arms to the subframe are disposable! When re-tightened, they stretch and do not provide the required force. Always buy new bolts (part number N90813202 for Rapid).
3. Ignoring wheel alignment: even if the car drives smoothly, the wheel alignment angles change after replacing the silent blocks. Without adjustment, tires will wear out within 5–10 thousand km.
4. Savings on lubrication: Before installing silent blocks, their rubber parts must be treated silicone grease (for example, Liqui Moly Silicone-Fett). This will prevent squeaking and extend service life.

Another common mistake is retightening of bolts. On Rapid The tightening torque of the levers is strictly regulated: 100 Nm + 90°. If you overtighten, the rubber insert of the silent block will be deformed, and it will quickly fail. Use a torque wrench - without it it is impossible to tighten the bolts correctly.

💡

Before installing new silent blocks, clean the seats in the lever from rust and dirt. Even a small speck of dirt can cause misalignment during pressing.

How to extend the life of silent blocks: prevention and care

Resource of silent blocks for ŠKODA Rapid depends not only on the quality of the parts, but also on the driving style and care of the suspension. Here are some tips to help delay their replacement:

• 🚘 Avoid sudden starts and braking on uneven surfaces. Strong jerks increase the load on the rubber inserts.
• 🛣️ Avoid potholes and speed bumps at low speeds. Impacts to the suspension are the main cause of rubber delamination.
• 🔧 Check clearances regularly in the suspension (every 15–20 thousand km). Play in ball or wheel bearings accelerates wear of silent blocks.
• 🧴 Treat rubber parts silicone grease once a year. This will prevent cracking from temperature changes.
• ⚖️ Monitor your tire pressure. Incorrect pressure changes the load on the suspension and reduces the life of the silent blocks.

If you often drive on dirt roads or in very dusty conditions, it makes sense install anthers on silent blocks (for example, from Febi or Corteco). They protect rubber from abrasive wear and extend service life by 20–30%. It is also useful to check the condition of the lever mounting bolts every 2-3 years - if they rust, it is better to replace them in advance.

⚠️ Attention: If on your Rapid Polyurethane silent blocks are installed, avoid washing the suspension under high pressure. A jet of water can penetrate microcracks in polyurethane and lead to its destruction in winter.

FAQ: Answers to frequently asked questions about silent blocks ŠKODA Rapid 2018

Is it possible to drive with worn silent blocks if they do not knock?

No, even if there are no knocks, worn silent blocks worsen handling and increase the load on other suspension elements. On Rapid this is especially critical due to the peculiarities of the suspension geometry: play in the silent blocks leads to uneven wear of the tires and accelerated destruction of the ball joints. At the first signs of wear (cracks, delamination of rubber), parts need to be replaced.

How long does it take to replace silent blocks in the service?

On average, the job takes 2–3 hours, if the lever assembly is changed. If the master presses out and presses in individual silent blocks, the time increases to 4–5 hours (due to the need for precise installation). Some services offer an “express replacement” in 1.5 hours, but this is fraught with errors during pressing.

Is it possible to install silent blocks from other VAG models?

Theoretically on Rapid 2018 suitable silent blocks from VW Polo (MQB platform) or Seat Ibiza, but there are nuances:

• Articles must match (6Q0407151/152 for lever assemblies).
• Individual silent blocks (for example, Lemförder 34147 01) are universal for the entire MQB line, but may differ in rubber hardness.
• Polyurethane bushings often require modification of the seats.

Before purchasing, check the catalogs ETKA or Elcats.

What is better: original levers or analogues?

Original levers (VAG) are guaranteed to last longer (100–120 thousand km), but their high price is often unjustified. High-quality analogues (TRW, Meyle) with proper installation, they last 80–100 thousand km, which is comparable to the original. Budget brands (Febi, Topran) are risky - their resource may not exceed 50 thousand km. If your mileage is more than 150 thousand km, it makes sense to consider polyurethane silent blocks (Sasic, Powerflex).

Is it necessary to do a wheel alignment after replacing the silent blocks?

Definitely! Even if you install the parts perfectly, the suspension geometry changes and the wheel alignment angles get lost. Without adjustment you will get:

• Uneven wear of tires (in 5–10 thousand km the tread can “eat away” to the cord).
• The car pulls to the side when driving in a straight line.
• Increased fuel consumption due to increased rolling resistance.

The cost of wheel alignment (1,500–2,500 rubles) will be recouped by the money saved on tires.
