The process of dismantling the rear of a car body Nissan Terrano often raises questions among owners who decide to carry out repairs or tuning themselves. Many people mistakenly believe that it is enough to unscrew a few visible bolts, but the actual design requires careful attention to hidden fasteners and plastic clips.
Incorrect actions can lead to damage to the paintwork, breakage of fragile clips, or deformation of the device itself. bumper. In this article we will analyze a step-by-step algorithm of actions that will help you safely remove the element without resorting to the services of service centers.
This procedure is especially relevant when replacing parking sensors, repairing cracks or installing a winch. Following the sequence of operations and using the right tools is the key to success when working on a car. Nissan Terrano.
Preparing the workspace and necessary tools
Before starting any physical impact on the body, it is necessary to provide access to the work area and prepare a set of keys. For Nissan Terrano You will need a set of sockets, including 10mm and 12mm sizes, and a Phillips screwdriver with a long shaft.
It is important to create conditions under which you can move freely around the car and look into the wheel arches. If you're working in a garage, make sure there's enough lighting to see the hidden fasteners inside the arch. Lack of light can result in stripped threads or a broken retainer.
- 🛠️ 10 and 12 mm sockets with ratchet
- 🔧 Phillips screwdriver (PH2) and flat screwdriver for clips
- 🧤 Gloves to protect hands from sharp metal edges
- 🧼 Rags and plastic cleaner (optional)
Don't forget to also prepare a container for storing the loosened bolts so as not to lose them in the grass or on the asphalt. Small parts are easily lost, and it is difficult to find the original mounting bolt bumper In the store it can be problematic due to the specifics of ordering spare parts.
⚠️ Attention: Make sure that the car is on a level surface and is secured with the handbrake. If you plan to remove the wheel to access the arches, be sure to place chocks under the front wheels.
Removing external mountings and wheel arches
Dismantling should begin with visible elements. Open the trunk and locate the lower mounts bumper on both sides. These are usually bolts that go through the reinforcement and are attached to the body. They need to be unscrewed completely.
Next we move on to the wheel arches. This is the most labor-intensive stage, since the main fasteners are located here. You need to look inside the rear wheel arch and find a row of screws connecting Nissan Terrano with a plastic fender liner and the bumper itself.
- 🔩 Unscrew 2-3 screws at the bottom of the arch
- 🔩 Unscrew 4-5 screws securing the bumper to the fender liner
- 🔩 Check for hidden clips in the middle of the arch
After removing the screws, you need to carefully bend the plastic fender liner to gain access to the hidden bolts, which often rust and stick. Use a flathead screwdriver to pry the clips out, but do so carefully to avoid damaging the body's paintwork.
☑️ Dismantling fasteners
If the bolts in the arches do not unscrew, do not use excessive force, otherwise you will break the threads. It's better to use a penetrating lubricant and give it time to work. Ignoring this step may result in the plastic simply cracking when trying to remove the bumper.
⚠️ Attention: Plastic fasteners in arches are very fragile, especially in winter. If they are stuck, gently warm them up with a hairdryer before attempting to remove them.
Disconnecting electrical connectors and sensors
After all the mechanical fastenings have been loosened, but the bumper is still held in place by the latches, you need to turn off the electrics. On the rear bumper Nissan Terrano parking sensors and fog lights are often installed that require careful removal.
Don't pull the wires! This is the main mistake of beginners. You need to find the connector, press the latch and gently pull it to the side. If the connector is stuck, use a thin screwdriver to pry up the retainer. Check that the contacts are not left in the connector.
- 🔌 Locate the parking sensor connectors on both sides
- 🔌 Disconnect the fog light wiring (if equipped)
- 🔌 Release the wiring harnesses from the plastic clip holders
It is important to check the condition of the wires before completely removing the bumper. If the wire is stretched, it may break if the part moves suddenly. Make sure that the harness has enough length to allow the bumper to move 10-15 centimeters away from the body.
What to do if the connector does not come off?
Use a plastic card or a thin screwdriver to press the latch. Do not use force, otherwise you will break the plastic tab.
Sometimes the sensors stick to the bumper body due to dirt and time. In this case, carefully pry up the sensor housing and remove it without disconnecting the wire, if the cable length allows it. This will save time during reassembly.
Before disconnecting the connectors, take photographs of their location and the color of the wires. This will help avoid confusion during installation, especially if you have non-standard electronics installed.
Latch release technology and bumper removal
This is the final stage and requires two people. One person should lift the bumper slightly to release the top rails, and the second should pull it towards themselves to release the side clips. Sudden movements are excluded, as the plastic may crack at the attachment points.
The top latches, which are often located under the trunk, are released first. Then you need to evenly pull the bumper to the sides, gradually snapping off the side fastenings. Bumper Nissan Terrano It rests on powerful plastic “ears” that fit into the grooves of the body.
- 🚗 Two people take the bumper by the lower edges
- 🚗 Smoothly pull towards themselves, overcoming the resistance of the latches
- 🚗 Move the bumper so that the wires are not stretched
After the bumper is disconnected from the body, it must be carefully removed from the work area and placed on a soft surface. Under no circumstances should you place it face down on asphalt or concrete, as this is guaranteed to damage the paintwork.
The main difficulty in dismantling lies not in unscrewing the bolts, but in correctly releasing the plastic latches without breaking them.
If the bumper does not budge, check all the arches and the lower part again. Often, owners forget about one or two hidden bolts that remain unscrewed. Trying to remove the bumper by force will result in the plastic breaking.
Design features and possible problems
Bumper design Nissan Terrano has its own nuances that distinguish it from other crossovers. For example, a bumper reinforcement can be attached to the body through special gaskets, which harden over time and interfere with removal.
It is also worth considering that the types of fasteners may differ for different years of manufacture. Some versions use metal clips, while others use only plastic clips. This affects the complexity of the work and the likelihood of damage to parts during dismantling.
| Mounting type | Location | Features | Tool |
|---|---|---|---|
| M8 bolts | Lower part, under the trunk | Strongly stick to the body | 12 mm head |
| Self-tapping screws | Wheel arches | Many hidden under the fender liner | Phillips screwdriver |
| Plastic clips | Side grooves | Fragile, require care | Flat head screwdriver |
| Latches | Upper part | Hold the main load | Hands (raise) |
If you encounter rust on the bolts, do not try to unscrew them right away. Use WD-40 or similar and let it sit for 10-15 minutes. This will save the thread and save your nerves.
⚠️ Attention: When working with rusty bolts, use high-quality tools. Cheap sockets can lick off the edges, making it almost impossible to unscrew the bolt without drilling.
Also pay attention to the condition of the guide grooves. If they are damaged, the bumper may not fit into place when reinstalled and gaps will be visible. In this case, it may be necessary to replace the grooves or use special repair bushings.
- Once a year
- Once every 3 years
- Only in case of an accident
- Never
Reinstallation and final check
Reinstalling the bumper is done in the reverse order of removal. First you need to carefully fit the top latches, then align the side parts and fix them. Make sure that all the grooves are in place until you hear a characteristic click.
After this, connect all electrical connectors and check the operation of the parking sensors and headlights. Do not fully tighten the bolts until the bumper is completely seated. Otherwise, distortions and gaps may occur.
- 🔧 Attach the top latches first
- 🔧 Align the side gaps around the entire perimeter
- 🔧 Tighten all bolts and screws
At the end of the work, check if there are any extra gaps between the bumper and the body. They should be uniform on both sides. If the gap is larger on one side, you may not have pressed the latch all the way or may have misaligned the bumper during installation.
Pay special attention to the wheel arches. The fender liners should fit tightly to the bumper, without gaps. If they come off, you may not have screwed the screws in completely or damaged the fasteners.
Correct installation of the bumper guarantees the absence of vibrations and extraneous noise when the car is moving.
