Repair kit for trapezoid wipers Nissan Note E11: selection and replacement

Introduction: Why the windshield wiper mechanism breaks down

Owners Nissan Note first generation (E11 body) often encounter a problem when the wipers stop working correctly. The mechanism begins to make strange sounds, operate jerkily, or completely jam. The main reason lies in the wear of the plastic bushings and hinges inside the trapezoid, which is subject to constant vibration and exposure to an aggressive environment.

Many car enthusiasts immediately run to the store for a new trapeze assembly, but this is not always economically justified. Often it is enough to buy a quality trapeze repair kit and replace only worn elements. This will allow you to return the factory smoothness and significantly save your budget, since the cost of a complete assembly is several times higher than a set of bushings and gears.

Repair of the windshield wiper mechanism Nissan Note E11 - This is a task that you can handle yourself if you have a basic set of tools. The main thing is to carefully select spare parts and follow the disassembly sequence so as not to damage the plastic latches and the electric motor.

Diagnosis of faults and wear symptoms

Before you go shopping, you need to be sure of the cause of the breakdown. Characteristic symptoms of trapezius malfunction Nissan Note appear in the form of a characteristic crackling or squeaking sound when the windshield wipers are turned on. If the motor works, but the thrust is not transmitted to the levers, the problem lies in the breakdown of the plastic gear inside the electric motor.

Another common scenario is play in the joints of the rods. You may notice that your wipers are delayed or stop in a different position. In this case, the broken ones are to blame plastic bushings, which no longer hold the metal rod with the required force. Ignoring these signs may lead to motor burnout due to increased load current.

For an accurate diagnosis, it is necessary to remove the plastic grille under the windshield and visually inspect the unit. Try rocking the wiper arms with your hand while the ignition is off. If you feel significant play or hear a crunching sound, it means trapezoid mechanism requires immediate intervention. Often the problem is aggravated by dirt and moisture getting inside the hinges.

Choosing a quality repair kit for Nissan Note E11

There are many offers on the aftermarket for Nissan Note E11, but quality varies from original parts to cheap soft plastic counterparts. The original is often supplied only assembled, which makes purchasing a repair kit from third-party manufacturers a more attractive option. However, you need to be careful: cheap plastic will quickly break again after a couple of months of use.

When choosing a set, pay attention to the contents. Good trapeze repair kit should include not only bushings, but also new washers, retaining rings, and sometimes lubricant for friction units. It is important to check the presence of the drive gear if your problem is related to the motor. The absence of high-quality lubricant in the kit is a red flag indicating low quality of the product.

• 🔍 Look for repair kits with the addition of Teflon bushings, they are more wear-resistant than standard nylon.
• 🛠 Make sure that the kit contains a star wrench or a special tool for removing retaining rings.
• 🚫 Avoid kits where the bushings look too soft or have uneven molding edges.

It is worth noting that some manufacturers offer universal kits that are suitable for several Nissan models. However for Nissan Note E11 It is better to look for specialized parts, since the geometry of the trapezoid has its own unique features. Incorrectly selected bushings can lead to misalignment of the rods and accelerated wear.

An investment in a proven brand will pay off in the absence of repeated repairs.

Necessary tools and preparation for work

Before starting work, prepare your workplace and the necessary tools. You will need a standard set of wrenches and sockets, including 10 mm and 12 mm to remove fasteners. You also cannot do without a Phillips screwdriver and a flat-head screwdriver to carefully pry up the plastic elements and remove the clips.

To disassemble the trapezoid mechanism itself, a special tool or a set of asterisk wrenches (Torx) is often required, since many fastening bolts have a non-standard head. Also prepare a container for small parts so you don't lose bolts and nuts while working. Having a flashlight will help you better see the components in hard-to-reach places under the grille.

Be sure to disconnect the battery before starting work to prevent accidental activation of the wipers and risk of electric shock or mechanical injury. Remove the negative terminal and place it securely to the side. This is a standard safety procedure for any manipulation of vehicle electrical equipment.

⚠️ Attention: When removing the plastic grille under the windshield, act very carefully, as the plastic clips are on Nissan Note E11 often become brittle over time and can easily break if handled carelessly.

It is also recommended to purchase a can of brake cleaner or carb cleaner to remove old grease and dirt before installing new bushings. A clean joint surface will ensure a longer service life for the new one. repair kit.

Step-by-step instructions for replacing bushings and gears

The replacement process begins with removing the plastic trim under the windshield. Unscrew all visible screws and carefully pry the latches to remove the grille. After this you will have access to the trapezoid mechanism and the electric motor. Inspect the electric motor mount; it is usually held on by three bolts.

The next step is removing the trapezoid itself. Disconnect the rods from the wiper arms, having previously marked their position so as not to disturb the installation angle during assembly. Unscrew the bolts securing the entire structure to the car body. Carefully remove the trapezoid from the engine compartment, being careful not to damage the wiring and washer hoses.

Now you can start disassembling the mechanism. Remove the retaining rings from the rod axles and remove the old bushings. If you are changing a gear in a motor, you will have to disassemble the motor housing. Clean all seats of old grease and corrosion. This is a critical step, as dirt can quickly destroy new parts.

Install new bushings from repair kit into the trapezoid body. Apply fresh lubricant to all rubbing surfaces. Reconnect the rods, making sure they move freely without binding. When installing the gear in the motor, make sure that the grooves and marks match so that the mechanism operates in the correct mode.

Features of disassembling the wiper motor

To access the gear inside the motor, you need to carefully remove the cover secured with plastic latches. Inside there is a gearbox with a plastic gear, which often breaks. Be extremely careful not to break the small pins securing the cover.

After assembling the trapezoid, perform a preliminary stroke test manually. Make sure there are no jams or play. Only after this can the unit be returned to its place. Install the trapezoid under the windshield, secure with bolts and connect the rods to the arms.

Trapezoid element	Symptoms of wear	Recommended replacement interval
Plastic bushings	Backlash, knocking, uneven movement	50-70 thousand km
Reducer gear	Clicks, skipping, motor noise	If signs of damage appear
Retaining rings	Loss of rods, complete play	At every disassembly
Lubrication	Dry running, creaking	Every repair

⚠️ Attention: When reassembling, do not over-tighten the trapezoid mounting bolts, as this may deform the plastic housing and lead to misalignment of the mechanism, which will cause repeated wear of the new bushings.

Assembly and testing of system functionality

After installing the trapeze on the car, you need to connect the electrics and check the operation. Before putting on the plastic grille, turn on the ignition and test the wiper modes. Notice how they stop in the down position. If they do not fold correctly, the arms may need to be adjusted.

Check operation in different modes: single actuation, intermittent operation and constant operation. Make sure the motor is quiet and does not overheat. If everything is functioning normally, you can move on to the final assembly. Install the plastic grill under the windshield and secure all the screws.

• ✅ Check the tightness of the installation site to prevent water from entering the interior.
• ✅ Make sure that the levers do not touch the glass in extreme positions.
• ✅ Test the operation of the windshield washer along with the wipers.

It is important to check whether the wiper arms do not touch each other or body parts. If you notice any unusual sounds, stop work immediately and recheck the assembly. Most often, the problem lies in an incorrectly installed rod or lack of lubrication.

If you did everything correctly, the wipers will work as smoothly and silently as on a new car. Regular maintenance and timely replacement of consumables will avoid costly repairs in the future.

Common repair mistakes and how to avoid them

One of the most common mistakes is not cleaning the seats. Many craftsmen simply insert new bushings into dirty holes, which leads to rapid wear. Dirt acts as an abrasive, breaking down the plastic. Thorough cleaning and blowing with compressed air is mandatory before installing new parts.

Another mistake is using the wrong lubricant. Do not use lithol or grease, as they can corrode the plastic or attract dust. Use special lubricants for plastic components or silicone grease. The wrong choice of lubricant can lead to you hearing the characteristic creaking noise again after a month.

Sometimes during assembly they forget to install the retaining rings or do not install them completely. This leads to the rods flying out of their seats when the mechanism is operating. Always visually check that each part is securely attached before calling the job complete.

Some car enthusiasts are trying to save money and use old retaining rings, even if they have lost their elasticity. This is strictly not recommended, since the ring must tightly fix the axle. Use only new elements from the repair kit to guarantee reliability.

⚠️ Attention: If you are not confident in your abilities or do not have the necessary tools, it is better to entrust the replacement to professionals, as incorrect installation can lead to damage to the windshield or electric motor.
