Nissan Navara is one of the most popular pickup trucks on the Russian market, combining durability, cross-country ability and comfort. However, even such a reliable car requires attention to the condition of the body, especially in harsh climates, aggressive reagents and off-road conditions. In this article we will analyze the body structure Navara (including models D40 And NP300), typical problems, corrosion protection methods and repair nuances.

A special feature of the pickup body is the combination of a cargo platform and a passenger cabin, which places increased demands on rigidity and anti-corrosion treatment. Owners often encounter rust on the sills, arches and bottom, as well as the consequences of mechanical damage during off-road use. We will tell you how to extend the life of a body, what spare parts to choose for repairs and what to look for when buying a used one. Navara.

Body structure Nissan Navara: materials and features

Body Nissan Navara Made from high strength steel using galvanized panels in key areas. In models D40 (2005–2014) and NP300 (since 2014) different assembly technologies are used:

  • 🔧 D40: frame design with a separate body, which simplifies repairs, but increases weight. The spars and cross members are made of thick steel (2–3 mm), and the outer panels are made of thinner metal (0.8–1.2 mm).
  • 🚛 NP300: Lightweight frame with integrated body components for improved rigidity. Aluminum parts are used in the hood and trunk lid (in some versions), which reduces weight but complicates repairs.
  • 🛡️ Both generations have factory anti-corrosion treatment, but its quality varies depending on the market. For example, cars for the Middle East were often supplied with minimal protection.

Particular attention is paid to the area between the cab and the cargo platform - reinforced brackets and rubber seals are used here to prevent moisture from entering. However, it is this place that most often becomes a hotbed of corrosion due to the accumulation of dirt and reagents.

Weak points of the body: where to look for rust and damage

Even with careful use, the body Navara has vulnerable areas that require regular inspection. Here are the typical problems:

Body area Typical defects Reasons
Thresholds and lower parts of doors Perforation corrosion, paint blistering Accumulation of moisture, reagents, mechanical chips
Wheel arches (front and rear) Rust on edges, cracked welds Stone impacts, lack of anti-gravel, poor ventilation
Bottom and side members Metal rotting, loose suspension fastenings No processing, off-road use
Connection between cabin and platform Depressurization of seals, corrosion of brackets Vibrations, water entering through cracks
Hood and fenders Chips of paint, dents from stones No protective film, aggressive washing

The critical area is the rear of the frame under the load bed: cross members often rot here due to dirt accumulation and insufficient ventilation. When buying used Navara Be sure to check this area with an endoscope or on a lift.

⚠️ Attention: If bubbles appear under the paint on the sills or arches, this is a signal of the onset of corrosion. Do not delay repairs - rust quickly eats through the metal, especially in places where welds are made.

Anti-corrosion treatment: what and how to protect

Factory body treatment Nissan Navara rarely lasts longer than 3–5 years, especially in Russian conditions. To prevent corrosion, a comprehensive solution is needed:

  1. Washing and cleaning. Regularly remove dirt from hidden cavities (sills, arches, underbody) using a high-pressure cleaner. Pay special attention to drainage holes in doors and bumpers.
  2. Application of anti-corrosion compounds.
    • 🔹 ML oils (For example, Noxudol or Dinitrol ML) - for hidden cavities.
    • 🔹 Bitumen mastic (For example, Body 930) - for the bottom and wheel arches.
    • 🔹 Paraffin compounds (For example, Tectyl) - to protect welds.
  • Additional protection. Install mud flaps on the arches, protective film on the hood and lower parts of the doors, and also treat the cargo bed with an anti-slip coating (for example, Line-X).

    • For models NP300 Acid or alkali based compounds cannot be used with aluminum body elements - they destroy the protective oxide layer. The best choice is specialized products for aluminum (for example, ACF-50).

    Body repair: original spare parts vs analogues

    In case of body damage Nissan Navara The owner is faced with a choice: buy original parts or analogues. Let's look at the pros and cons of each option.

    Original spare parts (Nissan or Renault, since Navara And Alaskan have common details):

    • ✅ Perfect fit and compatibility with bindings.
    • ✅ Guaranteed quality of metal and paintwork.
    • ❌ High price (for example, original front bumper for NP300 costs 40–60 thousand rubles).
    • ❌ Long delivery times (especially for rare parts).

    Analogs (non-original spare parts):

    • 💰 The price is 2–3 times lower (for example, a bumper from Febi or Hella will cost 15–25 thousand rubles).
    • ⚠️ Risk of inconsistency in fastenings or metal thickness (especially from cheap Chinese manufacturers).
    • 🔍 Before purchasing, check reviews on forums (for example, NavaraClub.ru) and check the articles with catalogs.

    For critical elements (spars, cabin reinforcements), it is recommended to use only the original or certified analogues from Bosch, TRW or Meyle. For external panels (fenders, hood), you can consider high-quality analogues with a guarantee against chips.

    💡

    When purchasing used spare parts for Navara Be sure to check them for hidden corrosion. For example, thresholds often rust from the inside, which is not visible upon superficial inspection. Use a magnet to check the thickness of the metal - if it does not attract, the part is already rusted.

    Body tuning: from protection to aesthetics

    Many owners Nissan Navara modify the body not only to improve appearance, but also to increase practicality. Popular tuning areas:

    • 🛡️ Protective elements:
      • Installation of metal bumpers with a winch (for example, from ARB or Ironman 4x4).
      • Reservation of the bottom and fuel tank (relevant for off-road use).
      • Protective arches for headlights and windows.
    • 🎨 Aesthetic changes:
      • Vinyl stickers and airbrush.
      • Window tinting (allowed according to GOST - not less than 70% light transmission for the front windows).
      • Installing LED running lights in the bumper or radiator grill.
    • 🚚 Practical improvements:
      • Installing an awning or hard top on the platform.
      • Additional tool boxes in the cargo area.
      • Mounts for bicycles, skis or ladders to the cabin roof.

    When tuning, it is important not to disturb the factory geometry of the body, especially if the car is used in difficult conditions. For example, installing a bumper that is too heavy can lead to sagging of the front suspension or cracks in the side members.

    ⚠️ Attention: When installing a winch on a bumper, check its load capacity. For Navara D40 maximum load on the front bumper is 150 kg, for NP300 - up to 200 kg. Exceeding this value may deform the frame.
    How to check body geometry after an accident?

    After an accident or major body repair Navara it is necessary to check the geometry on the slipway. Pay special attention to the following parameters:

    - The distance between the centers of the wheel arches (must be the same on the right and left with a tolerance of ±3 mm).

    - Installation angles of the front and rear wheels (camber/toe).

    - Flatness of the bottom (checked with a laser level).

    - Alignment of side members (deviation of more than 5 mm requires correction).

    If the geometry is compromised, it will lead to uneven tire wear, poor handling and the risk of suspension failure.

    Buying used Nissan Navara: what to look for in the back

    When choosing a used one Navara body is one of the key evaluation criteria. Here is a checklist for inspection:

    1. Corrosion check:
      • Use a flashlight and mirror to inspect hidden cavities (thresholds, arches, interior door surfaces).
      • Check the condition of the welds on the frame - they should not be covered with fresh paint (a sign of hidden repairs).
      • Pay attention to the seals between the cab and the platform - if they are cracked, there is a high probability of corrosion underneath.
    2. Geometry rating:
      • Close all doors and check the uniformity of the gaps (should be the same around the entire perimeter).
      • Look at the joints of the panels - if they do not match, the body is broken.
      • Check the operation of the locks and hinges - if the door sag, the opening may be deformed.
    3. Paint coating analysis:
      • Use a thickness gauge to check the paint layer. Norm for Navara - 100–150 microns. If the indicator is above 200 microns, the car is painted.
      • Examine the body from different angles - non-original paint often differs in shade.

    Pay special attention to the loading platform: check the condition of the sides, fastenings and coating. Often the previous owners transported heavy loads, which led to deformation or cracks. Also inspect the towbar mounts (if installed) - they should not be rusty or bent.

    💡

    Upon purchase Navara with a mileage of more than 100 thousand km, be sure to check the condition of the side members. Their corrosion or deformation can make the car unsafe for use, even if the body looks normal on the outside.

    Frequently asked questions about the body Nissan Navara

    Is it possible to wash Navara in winter, if there are chips on the body?

    Yes, but with caution. When water gets into the chips, it expands when it freezes and accelerates corrosion. After washing, thoroughly dry the body (especially the sills and arches) and treat any chips anticorrosive in a can (For example, Krown or Rust Stop). Avoid high pressure washing in temperatures below -10°C.

    Which anti-gravel is best for arches Navara?

    For wheel arches it is recommended to use polyurethane or rubber compounds (For example, 3M Undercoating or Liqui Moly Unterbodenschutz). They are elastic, do not crack due to vibrations and adhere well to plastic fender liners. An alternative is liquid rubber (Plasti Dip), but it is less durable.

    What to do if rust appears on the thresholds?

    Algorithm of actions:

    1. Clean the rust down to bare metal (with a brush, a grinder or chemicals like Neomid 570).
    2. Treat the surface rust converter (For example, Tsinkar).
    3. Apply primer with zinc (For example, Body 960).
    4. Paint the threshold in the body color (use car enamel in a can with color code Nissan).
    5. For protection from the inside, pour into the threshold ML oil through technological holes.

    If the rust is through, you will need cutting out the damaged area and welding a patch.

    How much does body painting cost? Navara completely?

    The cost depends on the region and service station level:

    • 🔹 Budget option (without removing parts, local painting): 30–50 thousand rubles.
    • 🔹 Intermediate level (removal of bumpers, headlights, full preparation): 80–120 thousand rubles.
    • 🔹 Premium (complete disassembly, anticorrosive treatment, painting in a chamber): 150–250 thousand rubles.

    For NP300 with aluminum elements the price may be 20–30% higher due to the complexity of surface preparation.

    Is it possible to install on Navara D40 body parts from NP300?

    No, these models have different body geometry and mountings. The exception is some small parts (mirrors, door handles, radiator grille), but even they may differ in connectors and seats. Always check spare parts catalogs by VIN code.
