Many owners are faced with a situation where the sash stops holding in the up position or the lock refuses to close the first time. Ignoring these symptoms can lead to serious consequences: from scratches on the bumper to complete structural failure. It is important to carry out diagnostics in time and understand whether the part requires complete replacement or whether restoration work can be done.
In this material we will analyze in detail all aspects related to the rear cover of a sedan Nissan Almera N16. You will learn how to distinguish the original from the analogue, which hinges most often fail, and how to fix the sagging yourself without contacting a service center.
Design features and typical problems
Rear door design on the model Nissan Almera N16 made in the form of a rigid metal panel, which is attached to the body by means of two massive hinges. Inside the sash cavity there are sound insulation elements, upholstery and, what is critically important, a lock mechanism with rods. The metal of the cover is thin enough to reduce the overall weight of the car, but it is also prone to corrosion where the paint has chipped.
The main problem that owners face after 10-15 years of use is stretching of the upper holes in the hinges. As a result, the lid begins to sag, and the bottom edge begins to cling to the bumper when closed. Also often observed is the breakdown of plastic bushings, which serve as dampers to soften the impact when closing.
⚠️ Attention: If you notice that when closing the trunk you hear a sharp metallic blow rather than a dull bang, immediately stop using it in this form. This is a sure sign that the latch has moved and further closing will result in dents in the bumper or deformation of the latch.
Owners often try to solve the sagging problem by placing washers under the mounting bolts, but this is only a temporary measure. Over time, the metal around the hole will finally deform and the bolt will simply pull out. That's why replacing hinges or their repair by welding metal is a more reliable solution than the constant use of gaskets.
Types of spare parts: original, analog or used?
When choosing a new trunk lid or individual elements such as hinges or a lock, the driver faces a difficult choice. There are three main categories of spare parts on the market: original parts from Nissan, high-quality analogues from third-party manufacturers and used parts from disassembly. Each option has its pros and cons that you need to consider before purchasing.
The original trunk lid ensures that all mounting holes line up perfectly and the metal thickness meets factory standards. However, the cost of such a part is often unreasonably high, especially considering the age of the model. Nissan Almera N16. In addition, finding a new original cover in stock can be extremely difficult.
- 🔍 Original detail: ideal geometry, but high price and shortage.
- 🔍 High-quality analogue: often cheaper, but may require modification of the holes.
- 🔍 Used option: cheap and available, but there is a risk of hidden corrosion and metal fatigue.
If you decide to look for a used cover, carefully inspect the internal cavity. Often a part looks fine on the outside, but water has accumulated inside due to clogged drain holes, causing the amplifiers to rot. Be sure to check the condition locking mechanism and the operability of the window lift drive (if it is included in the configuration).

Diagnosis of sagging and wear of hinges
The first sign that something is wrong with the closing mechanism is a change in the position of the lid when open. If it drops below the usual level or, conversely, does not rise all the way, this indicates problems with the hinges. Diagnostics begins with a visual inspection and checking for play.
Grasp the edge of the trunk lid and try to rock it up and down and to the sides. If you feel significant play at the top of the mount, it means that the holes in the hinges have widened. In some cases, play occurs due to wear on the hinge axis itself, which may be made of a softer alloy than the body.
⚠️ Attention: Do not try to open the trunk if the lid is very sagging and jammed at the lowest point. Brute force can lead to tearing off the lock cables or breaking the plastic levers of the mechanism.
For an accurate diagnosis, it is necessary to remove the trunk trim. This will allow you to assess the condition of the lock drive cables and the integrity of the plastic fasteners. It often happens that the hinge itself is intact, but the bushing through which the axle passes has worn out. Replacing just the bushing can save money, but requires special tools and skill.
Step-by-step instructions for replacing hinges
Replacing hinges is a procedure that requires patience and precision, but does not necessarily require fancy equipment. You will need a standard set of socket wrenches, penetrating lubricant (WD-40), and perhaps a helper to hold the cap in place. Start by preparing your work area and ensuring safety.
First you need to open the trunk and secure the lid in such a position that it cannot close accidentally. Then remove the decorative trim from the inside of the cover to gain access to the mounting bolts. Unscrew the nuts holding the hinge on the inside and the bolts on the outside.
☑️ Preparation for replacing hinges
After unscrewing all the fasteners, have a helper support the cover, as it may fall and damage the bumper or paintwork. Remove the old loop and try on the new one. Please note that the seats may have traces of corrosion, which must be cleaned before installing a new part.
When tightening bolts, use a torque wrench if you have one, or tighten with moderate force to avoid stripping the threads. After installation, check the geometry: the cover should fit into the opening evenly, without distortion.
Proper tightening of the hinge bolts is critical to prevent further sagging and corrosion at the mounting points.
Repair and replacement of the locking mechanism
If the trunk lid is difficult to open or, conversely, does not close completely, the problem often lies in the lock. Mechanism on Nissan Almera N16 consists of a body, a cylinder, a drive from a key and a cable from a button on the lid. Over time, the lubricant in the mechanism dries out and the plastic gears wear out.
Often the problem can be solved by simple cleaning and lubrication. To do this, you need to remove the lock, disassemble it and remove old dirt. Use a special lock lubricant, not thick oil, which can attract dust and clog the mechanism. Check the condition of the cable that connects the button to the lock.
- 🔧 Clean the mechanism from old grease and dirt.
- 🔧 Check the integrity of the plastic levers and gears.
- 🔧 Replace the cable if it has visible damage or stretching.
If the mechanical parts of the lock are damaged, repair may not be economically feasible. In this case, it is easier to replace the entire assembly. When installing a new lock, make sure that the rods are adjusted correctly, otherwise the button may not work.
⚠️ Attention: When replacing the lock, be sure to check the functionality of the central locking and alarm system, as incorrect installation can disrupt the operation of the entire vehicle security system.
Geometry restoration and painting
If the trunk lid has dents or signs of corrosion, it must be restored to its original appearance before installing new hinges or a lock. Corrosion is the body's main enemy, and if left unchecked, the metal can rot through and through in a matter of months.
Use a wire brush and sandpaper to remove rust. After stripping, be sure to treat the surface with a rust converter and then apply primer. This will create a reliable barrier between the metal and the aggressive external environment.
How to prevent rust from reappearing?
To protect against rust, use anti-gravel film on the lower edges and wash the car regularly to remove road chemicals. It is also useful to apply mastic to the inner cavity of the lid.
Painting is best done in several layers: primer, paint and varnish. If you are not confident in your skills, it is better to contact a professional service, since the color must exactly match the main body. An incorrectly chosen shade will be very noticeable.
Before painting, be sure to cover all rubber seals and plastic elements with masking tape to prevent paint from getting on them.

Why does the trunk lid of the Nissan Almera N16 not close completely?
The reason may be a sagging lid, worn out latch, or a clogged lock. Check the position of the latch on the bumper and lubricate the lock mechanism.
Is it possible to replace only one hinge?
This is technically possible, but not recommended. The hinges wear out simultaneously, and replacing only one can lead to a violation of the geometry and rapid wear of the new part.
How to stop squeaking when opening the trunk?
The squeaking noise is usually caused by metal-to-metal friction in the hinges. Apply lubricant (Lithol or special silicone grease) to the hinge axes and bushings.
Where is the best place to buy spare parts for Almera N16?
It is best to look for original spare parts at disassembly sites or in specialized online stores. Analogues may be cheaper, but their quality is often lower.
What to do if the cable for opening the trunk from the passenger compartment is broken?
The cable can be replaced separately without changing the entire lock. To do this, you need to remove the casing, disconnect the old cable and install a new one, adjusting its length.
