Crossover owners Nissan X-Trail T31 generations often face the need to replace fastening elements during body repairs. These cars, produced between 2007 and 2013, have a complex body kit fixation system, where each element has its own specific parameters. Loss or breakage of even one protective clip can lead to plastic rattling, moisture entering the engine compartment and, as a result, corrosion.
Purchasing original parts is often expensive, and searching for high-quality analogues requires a deep understanding of the markings. In this article we will look in detail at the types of mounts used on the model. T31, we will learn to distinguish the original from the fake and provide specific dimensions for ordering spare parts.
Typology of body mounts Nissan X-Trail T31
Exterior elements fastening system on Nissan X-Trail is not unified. Different units use different locking mechanisms, which is often misleading when doing DIY repairs. The main division occurs according to the type of expansion mechanism: rivet, screw and bushing.
The most common type is spacer clips, which are installed in a pre-prepared hole. When driving in the central part, the legs expand, which ensures reliable retention. Specific specifications are often used for the front bumper and radiator grille. clamps with antennae, which require care when dismantling, as the plastic on older cars becomes brittle.
- π© Threaded screw fasteners - used for fender liners and crankcase protection
- π Spacer clips (Push-pin) - the main type for body kits and thresholds
- π Clips with antennae - used in areas of high vibration
Particular attention should be paid to the fastenings located in the wheel arches. It uses long screw elements, which often corrode due to constant contact with reagents. Replacing such elements requires pre-treatment with a penetrating lubricant, otherwise the screw head may simply break off when trying to unscrew it.
Dimensions and specifications of original elements
When ordering components, it is critical to know the exact geometric parameters. An error in the diameter of the leg by even 1-2 millimeters will make the mount unusable. For Nissan X-Trail T31 There are several standard sizes that cover 90% of repair needs.
The most popular fasteners are 10 mm in diameter with a leg length of 20 to 30 mm, used for fixing fender liners and plastic protections. Smaller elements with a diameter of 8 mm are used for fastening decorative trims and interior elements facing the outer part of the body.
Below is a table with the main dimensions that must be taken into account when selecting analogues or ordering original spare parts. Please note the difference in length for different installation areas.
| Mounting type | Leg diameter (mm) | Leg length(mm) | Main Application |
|---|---|---|---|
| Screw (fender liner) | 10.0 | 25-30 | Lockers, underbody protection |
| Spacer (bumper) | 9.5 | 18-22 | Front and rear bumper |
| Clip with mustache | 8.5 | 15-18 | Radiator grille, trims |
| Extended retainer | 10.0 | 35-40 | Thresholds, bumper skirt |
β οΈ Attention: Use only new fasteners during assembly. Reusing old clips, especially the spacer type, is almost guaranteed to lead to their destruction during the next dismantling or detachment of the element from the body.
Dismantling problems and risks of plastic breakage
Working with clips on a car more than 10 years old requires maximum care. Plastic, when exposed to ultraviolet radiation and temperature changes, loses its elasticity, becoming similar to glass. Careless movement with a screwdriver can lead to cracks on the bumper or threshold, the repair of which will cost much more than purchasing new fasteners.
Before starting work, you need to prepare a special tool. Regular screwdrivers often slip and damage the surface. For safe removal, it is recommended to use a set of plastic spatulas and pullers, which allow you to apply force exactly at the desired point without deforming the surrounding plastic.

- π§ Clip remover - a special tool that captures the central part
- π₯ Construction hair dryer - for heating plastic in winter
If you plan to dismantle during the cold season, be sure to warm up the mounting area. Cold plastic Nissan X-Trail extremely fragile, and the clips may break before they are removed. Heating to 40-50 degrees will return the necessary elasticity to the material.
β οΈ Attention: Never try to pull a clip by the central part (stem) unless you are sure of its type. For many models, you first need to push the rod inward to release the spacer antennae, otherwise you will simply break the fastener.

Algorithm for replacing fasteners with your own hands
The process of replacing clips with Nissan X-Trail T31 does not require complex equipment, but must be performed consistently. Errors at the preparation stage can lead to damage to the paintwork or the plastic itself. It is important to follow the technology for removing old fasteners and installing new ones.
First you need to completely release the element that you plan to remove. Remove all visible screws and bolts. If the element is held only by clips, carefully pry it off with a spatula, starting from the edge where there are the least number of fasteners. Gradually move around the perimeter, releasing each fixation point.
βοΈ Preparing to replace clips
After removing the element, inspect the mounting holes. Dirt and rust often accumulate in them, which prevents the installation of a new fastener. Use a brush and compressed air to clean. If the hole is deformed, it can be carefully repaired with a round file or awl.
- π§Ή Cleaning - removing old grease and dirt from the hole
- π§ Lubricant - applying silicone to the new clip for easy entry
- π¨ Installation - gently hit with a rubber mallet or hand until it clicks
Installation of the new fastening is carried out until a characteristic click is heard. If there is no click, it means the clip is not in place and needs to be tapped a little more. However, if the force is too great, check the diameter of the leg - you may have chosen the wrong analogue.
What to do if the clip gets stuck in the bumper?
If the clip leg is broken and the spacer remains inside the bumper, use a thin drill bit with a diameter slightly smaller than the inner diameter of the clip. Carefully drill out the plastic of the clip, being careful not to damage the metal of the body, then remove the remains with pliers.
Proper cleaning of the mounting hole before installing a new clip increases its service life and prevents the element from spontaneously falling out.
The choice between the original and analogues
The spare parts market offers a wide selection of clips for Nissan X-Trail T31, from expensive original parts to cheap Chinese analogues. The difference in price can be significant, but the quality of materials also differs dramatically. Cheap plastic often has poor tolerances, resulting in poor adhesion.
Original clips from Nissan are made of impact-resistant polymer that retains its properties even at extremely low temperatures. They have a clear geometry, which ensures a tight fit. However, their cost makes purchasing a kit for the entire car impractical for budget repairs.
High-quality analogues from well-known brands of auto chemicals and accessories (for example, IPD or Stellox) are often an excellent alternative. They have acceptable plastic quality and the correct dimensions. The main thing when choosing an analogue is to carefully check the diameter of the leg and the length.
β οΈ Attention: Avoid purchasing βnonameβ clips without packaging and labeling. Often such products are made from recycled plastic, which crumbles in your hands the first time you dismantle it or even when you try to install it.
There is a universal set of clips that fits most Japanese cars. However for Nissan X-Trail T31 It is better to select specialized sets that take into account the features of this particular model. This will save time and nerves when searching for a suitable element.
Specifics of the radiator grille and headlight mounts
One of the most difficult areas to replace fasteners is the front of the car, where the grille and headlights are located. It uses miniature clips, which often break when trying to remove the grille for washing or replacing lamps.
On the model T31 the grille is attached to the bumper using specific clips with antennae. To remove them, you need to press on the central part and at the same time pull it towards you. If you do this with a jerk, the tendrils break off, and the grille remains hanging on one or two elements.
When replacing these elements, it is important not to confuse the left and right clips, as they may have different shapes of antenna bending. Incorrect installation will result in the grille being crooked or falling out over time.
Before removing the grille, take a photo of the installation process to remember the location of each clip. This will help avoid errors during reassembly.
To work in this area, it is best to use a thin tool, such as a narrow screwdriver with a rounded tip. This will allow you to carefully pry off the clip without touching adjacent parts or scratching the paint on the bumper.
Frequent errors during operation and repair
Many owners Nissan X-Trail make the same mistakes when caring for body parts. Ignoring minor damage to fasteners leads to serious consequences. For example, a missing clip on a fender liner can cause it to come off at high speed.
Another common problem is using glue instead of replacing clips. The glue can hold the element temporarily, but it cannot withstand vibration loads and temperature changes. Over time, this fixation weakens, and the plastic begins to dangle even more.
It is also not recommended to tighten the screw fasteners βall the wayβ with great force. This can lead to thread failure in the plastic or deformation of the part itself. The fastener should be tightened until resistance is felt, but without excessive force.
β οΈ Attention: Losing just 2-3 clips on the fender liner can lead to it jamming in the wheel arch and damaging the disc when turning the steering wheel.
Regular inspection of fasteners when washing your car will help identify the problem at an early stage. If you notice that the element is loose or the clip is sticking out, replace it immediately. This is a simple procedure that will save you from expensive repairs.
FAQ: Frequently asked questions from Nissan X-Trail T31 owners
How many clips do you need to replace all the fender liners?
To completely replace the fastenings of all four fender liners on Nissan X-Trail T31 Typically 20 to 24 screw clips are required. There are more of them in the front arches (6-7 pieces each), in the rear arches there are fewer (4-5 pieces each). It is recommended to buy a set with a small margin.
Is it possible to use universal clips instead of original ones?
Yes, universal clips are suitable if their diameter and length exactly match the original parameters. However, the original elements have a specific antennae shape, which is better suited for the holes in the body Nissan. If the universal analog is the right size, it will work reliably.
What should I do if the clip breaks inside the hole?
If the leg breaks and the spacer remains inside, use a thin drill or awl to carefully break the plastic of the clip from the inside. Then remove the residue with tongs. Do not try to pick it out entirely, as you may damage the metal of the body.
How can you tell if a clip needs replacing?
The main signs are the element rattling while moving, the presence of gaps between the part and the body, or if the clip does not stick out completely. Replacement is also necessary if, when the element was removed, the fastener remained in the body and not in the part.
Do I need special lubricant when installing new clips?
It is recommended to use silicone grease or graphite grease. This makes installation easier and prevents dirt from sticking, and also protects against corrosion at the plastic-to-metal interface. Do not use oil or WD-40 as they may corrode the plastic over time.
