Nissan Almera Classic (also known as Nissan Almera N16 or Samsung SM3 in some countries) is a reliable sedan, but even its windshield wiper mechanisms wear out over time. The windshield wiper trapezium is a key component that ensures synchronous operation of the blades, and its breakdown can result not only in discomfort, but also in danger on the road. In this article we will look at how choose the right trapezoid repair kit for your Almera Classic, recognize the symptoms of a malfunction and replace it yourself - without extra costs at a service station.

The peculiarity of the trapezoid in this car is its design with plastic bushings and metal levers, which become loose or break over time. The manufacturer does not always offer original spare parts at an adequate price, so we will analyze analogues from Febi, TRW And Sasicwhich have proven their reliability. You will also learn what tools are needed for repairs and how to avoid common mistakes, such as incorrectly adjusting the wiper travel after installation.

Signs of a faulty wiper trapezoid

The first “bells” about problems with the trapezoid are often ignored, attributing them to wear of the brushes or motor. However, if you notice at least one of these symptoms, it’s time to check the mechanism:

  • 🔊 Grinding or knocking when the wipers are working - a sign of wear on the plastic bushings or play in the joints of the levers.
  • 🌀 Uneven brush movement: one “lags”, the other moves jerkily.
  • 🛑 Full stop one of the brushes with the motor running (a hum is heard, but there is no movement).
  • 💧 Brushes do not return to its original position after turning off, remaining in an arbitrary place on the windshield.
  • 🔧 Switch handle play wipers - may indicate wear on the trapezoid gear.

Symptoms 2 and 3 are especially dangerous: if the brushes move asynchronously or one of them is jammed, this can lead to windshield damage due to uneven pressure. For example, at a speed of 60+ km/h, a faulty wiper creates a zone of turbulence that impairs visibility even with the washers running.

⚠️ Attention: If the wipers begin to “bounce” at high speed, immediately check the attachment of the trapezoid to the body. B Almera Classic The motor mounting bolts often become loose, which leads to vibrations and accelerated wear of plastic parts.

Articles and analogues: what to choose for Nissan Almera Classic

Original trapeze repair kit from Nissan has an article number 28530-9M00A (for models 2006–2012). However, its price often exceeds 5–7 thousand rubles, which is impractical for a car of this class. Fortunately, there are proven analogues:

Manufacturer Article Price, ₽ Features
Febi 22316 2 800–3 500 Complete set with metal levers and plastic bushings. New mounting bolts are included.
TRW JWG1001 3 200–4 000 Reinforced bushings, suitable for Almera Classic And Samsung SM3. 2 year warranty.
Sasic 2005010 2 500–3 000 A budget option, but requires additional lubrication of the bushings before installation.
Nipparts J47-10001 3 000–3 800 The kit includes rubber boots to protect the hinges.

When choosing, pay attention to complete set: Some repair kits do not include motor mounting bolts or plastic bushings (you have to buy them separately). Also check if the part is suitable for your year of manufacture - in Almera Classic 2006–2008 and 2009–2012 There may be slight differences in trapezoid attachment.

Tools and preparation for replacement

To replace the trapezoid wipers with Nissan Almera Classic you will need:

  • 🔧 A set of sockets and ratchet wrenches (a head on the 10 mm And 12 mm).
  • 🔨 Flat and Phillips screwdrivers (for removing plastic panels and clips).
  • 🧴 Grease for plastic bushings (For example, LIQUI MOLY Kunststoff-Fett).
  • 🔗 Torque wrench (for tightening bolts with torque 8–10 Nm).
  • 🧲 Magnetic holder (so as not to lose small parts when disassembling).

Before starting work disconnect the battery (remove the negative terminal) - this will prevent the wipers from accidentally turning on during repairs. We also recommend take a photo of the starting position of the trapezoid (especially levers) - this will help to correctly assemble the mechanism back.

Disconnect the battery (remove the "-" terminal)

Remove the wipers (unscrew the fastening nuts)

Remove the plastic trim under the windshield

Prepare lubricant for new bushings

Check the completeness of the repair kit -->

⚠️ Attention: If you are replacing a trapezoid during the cold season, do not use WD-40 to lubricate bushings. This liquid washes away the factory lubricant and freezes at low temperatures, which will lead to jamming of the mechanism. Use only specialized greases.

Step-by-step instructions for replacing a trapezoid

The replacement process can be divided into 3 stages: removing the old trapezoid, installing a new one and adjusting. Let's look at each step in detail.

1. Dismantling the old trapezoid

Start by removing the wipers: unscrew the mounting nuts (usually 13 mm) and remove the brushes from the shaft. Then:

  1. Remove the plastic trim under the windshield (it is secured with clips and bolts 10 mm).
  2. Disconnect the wiper motor power connector.
  3. Unscrew the 3 bolts securing the trapezoid to the body (two in front and one in the back, under the motor).
  4. Carefully pull out the trapezoid together with the motor through the right side (passenger side).

2. Installation of a new repair kit

Before assembly lubricate all plastic bushings and hinge joints. Install the new trapezoid in reverse order, but note:

  • Tighten the fastening bolts diagonallyto avoid skew.
  • Do not use excessive force when tightening - the plastic bushings may crack.
  • Check that the trapezoid arms do not touch the body or other parts.

3. Adjustment and testing

After installation, turn on the wipers and check:

  • Synchronous movement of brushes.
  • No play in the initial position.
  • The tightness of the brushes to the glass (they should come off the glass by no more than 1–2 mm when moving).

If the brushes move unevenly, adjust the position of the trapezoid by loosening the mounting bolts and slightly moving the mechanism.

💡

After replacing the trapezoid, treat the rubber wiper seals with silicone grease - this will extend their service life and reduce the load on the new mechanism.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing a trapezoid. Here are the most common:

  • 🔧 Re-tightening of fastening bolts — leads to deformation of plastic bushings and jamming of the mechanism. Use a torque wrench!
  • 🧴 Lack of lubrication on new bushings. Without it, the trapezoid will last no more than 1–2 seasons.
  • 🔄 Incorrect assembly of levers - if you mix up the left and right levers, the brushes will move in antiphase.
  • 🔌 Damage to the motor connector when disconnected. Always pull on the connector housing, not on the wires!

Another common problem is incompatibility of the repair kit with the year of manufacture. For example, a trapezoid for Almera Classic The 2006 may not fit the 2011 model due to changed arm geometry. Always check the article by the vehicle's VIN code.

What to do if after replacement the wipers work jerkily?

If the brushes move unevenly, check:

1. Correct installation of the levers (they must be symmetrical).

2. Tighten the trapezoid mounting bolts (loosen and retighten to the correct torque).

3. Condition of the motor gear - it may be worn out and requires replacement.

If the problem persists, try lubricating the trapezoid hinges graphite lubricant (it bears loads better).

Cost of work at a service station vs. do-it-yourself repair

Prices for replacing trapezoidal wipers in services vary depending on the region:

Service type Cost of work, ₽ Lead time
Official dealer Nissan 4 500–6 000 2–3 hours
Independent service 2 500–3 500 1–1.5 hours
DIY repair 0 (only cost of spare parts) 1.5–2.5 hours

As you can see, DIY replacement saves up to 60% from the cost of work at the service station. However, if you are not confident in your abilities, it is better to entrust the repair to professionals - installation errors can lead to damage to the wiper motor (price of a new one - from 5 thousand rubles).

💡

If you have never repaired a trapezoid, practice removing and installing wipers - this will help you understand the principle of operation of the mechanism and avoid mistakes.

FAQ: Frequently asked questions about trapezoidal wipers Nissan Almera Classic

Is it possible to repair an old trapeze instead of buying a new one?

Theoretically, yes - if the problem is only in worn bushings, they can be replaced separately (the article number of the bushings is 28535-9M000). However, in practice, plastic levers lose strength over time, and even after replacing the bushings, the trapezoid can quickly fail. The repair kit will not cost much more, but will last longer.

How often should the wiper blade be lubricated?

It is recommended to lubricate plastic bushings and hinges every 20–30 thousand kilometers or before the rainy season. Use lubricants based on lithium or molybdenum - They are resistant to water washout.

Why do the wipers move too slowly after replacing the trapezoid?

This may be caused by:

  1. Insufficient lubrication of the bushings (add lubricant and check the movement of the mechanism).
  2. Weak motor fastening (check the tightness of the bolts).
  3. Wear of the motor gear (replacement of the gear motor is required).
Is the trapezoid suitable for Samsung SM3 on Nissan Almera Classic?

Yes, these models are identical in windshield wiper design. Part numbers are completely interchangeable. The only difference is the logo on the plastic covers, but this does not affect functionality.

What should I do if, after replacing the trapezoid, the wipers do not return to their original position?

Most likely the settings have gone wrong motor limit switch. To return the wipers to the correct position:

  1. Remove the connector from the motor.
  2. Manually set the wipers to the down position.
  3. Reconnect the connector and turn on the wipers for 1–2 cycles. The mechanism must “learn” a new position.

If this does not help, check the limit switch circuit with a multimeter.
