Crossover owners Nissan Qashqai first generation, known in the J10 body, are often faced with the need to service the rear window cleaning system. Over time, the rubber element loses its elasticity, ceases to effectively remove dirt and leaves streaks, which is critical in rainy weather. Simply replacing the rubber insert or the entire brush requires dismantling the plastic lining and the lever itself, which may seem difficult for an inexperienced motorist.
Rear wiper removal procedure Nissan Qashqai J10 has its own design features that distinguish it from front windshield wipers. Unlike front wipers, where frameless systems are often used, the rear mechanism here is a classic lever with a latch hidden under a decorative cap. Incorrect actions when trying to remove it can lead to breakage of the plastic latch or damage to the paintwork of the body, so it is important to act consistently and carefully.
In this article we will analyze in detail all stages of the work: from preparing the necessary tools to the final installation of the new part. We will consider not only a standard brush replacement, but also a situation where it is necessary to remove the entire assembly to repair the mechanism or eliminate play. The right approach will allow you to save money on maintenance and extend the life of your glass cleaning system.
Preparing tools and work area
Before you begin dismantling, you need to organize a convenient workspace and prepare a minimum set of tools. Most operations on Nissan Qashqai J10 do not require complex equipment, but the presence of specific items will greatly simplify the task and reduce the risk of accidental damage. Make sure the vehicle is parked on a level surface and the battery is disconnected if you plan to work on electrical drive components.
You will need a set of Phillips and flat head screwdrivers and a small wrench or 10mm socket to remove the arm nut. Don't forget to have a clean rag or soft cloth ready to place under the wiper arm if it accidentally falls on the glass. This will prevent the formation of chips or cracks on the rear window due to careless movement.
To work you will need the following tools and materials:
- 🛠️ Medium-thick flat-head screwdriver for prying off plastic plugs;
- 🔧 10 mm socket or open-end wrench for unscrewing the nut;
- 🧼 Clean microfiber or soft cloth to protect glass and body;
- 💧 Silicone grease for processing the rotation axis after assembly;
- 🧤 Gloves to protect hands from contamination and sharp edges of plastic.
It is important to note that some owners use special brush removers, but in the case of Nissan Qashqai J10 this is often redundant. Standard tools allow you to complete the task in 15–20 minutes. The main thing is to act calmly and not to apply excessive force where the plastic should move from its place with light pressure.
⚠️ Attention: Before starting work, be sure to check that the rear wiper lever is in the neutral position and is not clamped by the spring of the mechanism. Sudden slipping of the tool can result in a deep scratch on the glass, which will be very difficult to remove.
Removing the decorative trim and finding the fastener
The first stage of dismantling is to remove the plastic decorative cover that hides the attachment of the lever to the actuator rod. This part often sticks or fits tightly to the body due to dust and dirt accumulated over years of use. An attempt to rip it out of place without prior preparation may lead to breakage of the latches that hold the cover in place.
Locate the seam between the plastic cover and the car body. Carefully insert a flathead screwdriver into this gap, placing a piece of cloth under it to avoid scratching the paintwork. Slowly and smoothly lift the lid, moving around the perimeter. You will hear a characteristic click, indicating the release of one of the latches. Repeat the procedure until the cover is completely removed.
After removing the cover, you will see a metal nut securing the lever to the splined drive shaft. Sometimes there may be an additional rubber gasket under this nut that should be saved for reinstallation. In some body modifications Nissan Qashqai J10 There may be a retaining ring present that requires special attention during removal.
If the cover cannot be removed, do not use brute force. Try rocking it slightly from side to side while lifting it up. Sometimes it helps to pre-treat the seams with a penetrating lubricant, such as WD-40, to dissolve contaminants that prevent the latches from coming out of the grooves.
⚠️ Warning: If you hear the plastic crunching when removing the cover, stop immediately. Most likely, the latch is deformed or jammed. Try a different angle of attack or use a hair dryer to lightly heat the plastic to make it more flexible.

Removing the windshield wiper arm
After the fastening nut is opened, you need to unscrew it with a 10 mm wrench. Do this carefully so as not to tear off the splines on the nut itself, as they are often made of soft metal. Unscrew the nut all the way, but do not remove it completely at once - this may lead to the loss of small parts or the lever falling onto the glass.
When the nut is completely unscrewed, it is necessary to remove the lever itself from the splined shaft. A problem that often arises here is that due to corrosion or a long period of time, the lever may “stick” to the shaft. Do not try to pull it off as this may break the drive shaft or damage the wiper mechanism inside the body.
For safe dismantling, use a special puller for the wiper arms. If such a tool is not at hand, you can use the rocking method: lightly rock the lever from side to side, while simultaneously lifting it up. This will help destroy the corrosion layer and free the splines.
If the lever does not budge, apply some penetrating lubricant to the joint between the shaft and the lever. Give the product a few minutes to work, then try rocking again. The main thing is to act patiently so as not to damage the spline surface, otherwise in the future the lever will not hold well and may fall off while moving.
List of actions when dismantling the lever:
- 🔑 Completely unscrew the fixing nut with a 10 mm wrench;
- 🔄 Gently swing the lever, freeing the slots from corrosion;
- 🔧 Use a puller or light force to remove the lever;
- 🛑 Never hit the lever or drive shaft with a hammer.
⚠️ Attention: If the drive shaft rotates along with the lever, it means that the mechanism inside the body is blocked or broken. In this case, further attempts to remove the lever may lead to serious damage to the drive, requiring complete disassembly of the trunk panel.
☑️ Preparation for dismantling the lever
Replacing the rubber brush and disassembling the mechanism
If your goal is only to replace the rubber insert, then after removing the lever from the shaft you can easily dismantle the brush itself. On Nissan Qashqai J10 The rear wiper usually has a metal frame design, where the rubber band is secured with special metal clips or plastic clips.
Inspect the mechanism for attaching the brush to the lever. It is often necessary to bend the metal tabs or press the plastic retainer to release the old rubber. Remove the worn part and compare it with the new part. Make sure that the length of the rubber and the shape of the bend are exactly the same as the original, otherwise it will not fit tightly to the glass.
Installing new tires is done in the reverse order. Insert it into the frame as far as it will go, making sure that all the latches snap into place. It is important to check that the rubber is not twisted or kinked. After this, the lever can be installed back on the drive shaft.
In some cases, owners prefer to replace the entire assembly, especially if the brush frame is heavily oxidized or deformed. This ensures a more secure fit and no backlash. To do this, simply remove the old assembly entirely and install the new one using the same fasteners.
How to choose the right brush?
When choosing rubber for the rear wiper of the Nissan Qashqai J10, it is important to consider the length: usually it is 13 inches (330 mm). Also pay attention to the type of fastening - this vehicle uses a specific hook or clamp, which may differ from the front wipers.
Eliminating backlash and adjusting the pressure
A common problem with the rear wiper Nissan Qashqai J10 is the appearance of play in the place where the lever is attached to the shaft. This leads to the wiper “jumping” on the glass, leaving streaks and making unpleasant sounds. The problem often lies in worn splines or weakened clamping springs.
To eliminate the backlash, it is necessary to check the condition of the spline pair. If the splines on the lever or shaft are worn out, you may need to replace the lever with a new one or use a washer to compensate for the gap. Sometimes tightening the nut helps, but this must be done with care so as not to damage the mechanism.
Adjusting the angle of contact of the wiper to the glass is also important for effective operation. If the rubber does not fit tightly, the glass will remain dirty. The angle of inclination of the lever can be slightly changed by installing it one slot higher or lower during installation. This will allow you to change the pressure on the glass.
After assembly, be sure to check the operation of the wiper in dry mode to make sure there are no vibrations or extraneous sounds. If the problem persists, the cause may be a worn spring inside the drive mechanism, which will require a more in-depth diagnosis.
Before tightening the lever mounting nut, apply a thin layer of graphite grease to the shaft splines. This will prevent re-sticking and ensure easy removal in the future.
Specifications and Parts Compatibility
To correctly select components and understand the design of the mechanism, it is useful to familiarize yourself with the technical characteristics of the rear window cleaning system. Knowing the parameters will help you avoid mistakes when choosing analogues and will ensure the longevity of the unit.
