Trunk lid trim <em>Nissan Pathfinder R51</em>: how to choose and replace correctly

Nissan Pathfinder R51 is a legendary crossover that is still in demand on the secondary market. But with age, even such reliable cars develop problems with body parts. One of the most vulnerable parts is trunk lid trim. It suffers from chips, cracks, fading and mechanical damage. In this article we will look at how to choose a high-quality lining, replace it yourself and avoid common mistakes.

Many owners Pathfinder R51 are faced with the fact that the original cover (article no. 90501-4M000 or analogues) are expensive, and analogues are not always suitable for fastenings. We analyzed the spare parts market, interviewed body repair specialists and collected unique data on the compatibility of linings from different manufacturers with original R51 fasteners. You will also find step-by-step instructions with photos that will help you save on service stations.

Why the trunk lining fails: the main reasons

Trim for trunk lid Pathfinder R51 made of plastic or fiberglass, which loses strength over time. Here are the key factors that accelerate wear:

• 🔥 Temperature changes: in Russia, the difference between summer and winter can exceed 60°C, which leads to microcracks in the material.
• 💥 Shocks and mechanical loads: Even minor accidents or careless loading of luggage will deform the pad.
• ☀️ Ultraviolet: sunlight destroys the top layer, causing fading and brittleness (especially in cheap analogues).
• 🧲 Vibrations: when driving off-road, the lining fastenings become loose, which leads to play and breakage.

According to service center statistics, 70% of lining replacements on R51 are associated with cracks in the area where the wiper or lock is attached. Another 20% are chips from gravel on the highway. The remaining 10% is due to manufacturing defects or unsuccessful repairs. If you notice that the lining begins to “play” when opening the trunk or the first cracks appear, this is a signal to action.

⚠️ Attention: Ignoring cracks in the trim can lead to moisture getting under the trunk trim. This causes corrosion of the metal cover and damage to the rear wiper wiring.

Types of linings: comparison of materials and manufacturers

There are three main materials available on the market. Each has its pros and cons:

Material	Benefits	Disadvantages	Average price (2026)
ABS plastic	Lightweight, does not rust, cheap	Fragile, fades in the sun, short service life (2-3 years)	3 500 — 6 000 ₽
Fiberglass (FRP)	Durable, UV resistant, long lasting (5+ years)	Heavier than plastic, more difficult to install, more expensive	8 000 — 12 000 ₽
Original plastic (Nissan)	Perfect fit, factory quality, warranty	Very expensive, long wait (made to order)	15 000 — 22 000 ₽

Among the manufacturers of analogues, the following stand out:

• 🏭 Febi (Germany) - optimal price/quality ratio, but sometimes there are problems with attaching the wiper.
• 🏭 Dorman (USA) - durable overlays, but may not match the color (requires painting).
• 🏭 TYC (Taiwan) - a budget option, but they often complain about fragility.
• 🏭 Kaplen (Russia) - inexpensive, but only for temporary replacement.

If you are choosing between the original and the analogue, keep in mind that original Nissan trim Comes with pre-applied primer and has an exact match for the mounting holes. Analogues often require modification - drilling new holes or adjusting to size. For example, at Febi the lock cutout may not match, but TYC — mount for the wiper.

How to choose the right pad: part numbers and compatibility

For Nissan Pathfinder R51 (2005–2012) there are several options for linings depending on the configuration and year of manufacture. Main articles:

• 📌 90501-4M000 - standard cover for most R51 (without camera).
• 📌 90501-4M001 — option with a cutout for a rear view camera (for versions with parking sensors).
• 📌 90501-4M025 — overlay for restyled models (2010–2012) with a modified shape.

Before purchasing, be sure to check:

1. Availability camera cutout (if installed).
2. Coincidence mounts for wiper (on some analogues the holes are shifted by 5–10 mm).
3. Color code (original color for R51 - KAD or KH3, but may vary depending on the year).

How to check the compatibility of the cover without removing the old one?

Take a photo of your pad on both sides (especially the fastenings) and compare it with the photo of an analogue from the seller. Please note:

- distance between bolt holes (should be 120 mm for R51);

- the shape of the locking cutout (in Restyle it is more rounded);

- the presence of reinforcing ribs (cheap analogues often do not have them).

If you buy a used pad, inspect it for hidden cracks (especially in the area where the wiper is attached) and check if the plastic is “leading” (this is a sign of overheating). Also check whether it has been painted - poor-quality painting can hide defects.

Step-by-step instructions for replacing the lining yourself

Replacing the lining with Pathfinder R51 does not require special skills, but will require accuracy and a set of tools. On average, the process takes 1.5–2 hours.

Step 1. Preparing and removing the old trim

1. Open the trunk and secure the lid in the upper position (you can use a rope or a stop).
2. Remove the plastic plugs from the mounting bolts (there are 6 of them - 3 on each side). Use a plastic puller to avoid scratching the paint.
3. Unscrew the bolts with a 10 mm wrench. Start with the top ones, then the bottom ones.
4. Disconnect the wiring connectors (if there is a heater or chamber). Remember their location or take a photo.
5. Carefully remove the old trim by pulling it towards you. If it gets stuck, use a flat-head screwdriver to pry it off from the edges.

Step 2. Preparing a new pad

If you purchased a non-original trim, you may need:

• 🔧 Fit the holes for the bolts (use a drill with an 8 mm drill bit).
• 🎨 Paint it in the body color (if the trim is primed).
• 🧴 Apply anti-squeak compound to rubber seals.

Step 3. Installation and fixation

1. Install the new trim into place, aligning all mounting holes.
2. Screw the bolts in by hand, then tighten with a wrench (do not overtighten as this will strip the threads!).
3. Connect the wiring connectors (if any).
4. Install plastic plugs on the bolts.
5. Check the operation of the wiper and trunk lock.

⚠️ Attention: When installing, do not use sealant on the bolts - this will complicate future replacement. It is enough to tighten the fasteners tightly and check that there is no play.

Tuning and modification of the trim: ideas for the Pathfinder R51

Replacing the trim is a good reason to update the appearance of the trunk. Here are some popular modifications among owners Pathfinder R51:

• 🖌️ Vinyl stickers: protect against chips and add individuality (carbon or matte finish options are popular).
• 🔦 LED backlight: Flexible strips along the contour of the trim improve visibility when opening the trunk at night.
• 🚿 Protective film: transparent armored film (for example, 3M Scotchgard) prevents chipping from gravel.
• 🔒 Additional lock: mechanical or electrical (for example, from Pop & Lock) to protect against burglary.

If you want to paint the trim a different color, please note that:

• For plastic you need a special primer (for example, Plastic Primer from Dupli-Color).
• Matte colors (eg. Gun Metallic) require additional varnish.
• Before painting, the lining must be degreased Antisilicon and matte with sandpaper P800.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the lining. Here are the most common:

1. Tightening the bolts → leads to cracks in the plastic or breakage of threads in the metal of the cover. Solution: Tighten the bolts to a maximum torque of 8 Nm.
2. Ignoring seals → without them, the lining will rattle on bumps. Solution: Buy new seals or use foam tape.
3. Incorrect painting → the paint peels off after a month. Solution: Use plastic primer and dry in a warm room for 24 hours.
4. Confusion with wires → a non-working wiper or camera. Solution: Take pictures of connectors before disconnecting.

Another typical problem is color mismatch new lining with body. Even if the article is the same, the shades may differ due to fading of the old paint. In this case, polishing the entire trunk or tinting the trim in a darker color will help.

⚠️ Attention: If after replacement the trunk wiper operates jerkily, check whether the trim is warped. The wiper motor mount could also have moved (part number 28550-4M000).

Caring for the pad: how to extend its service life

To make your pad last longer, follow these recommendations:

• 🧴 Washing: Use a soft sponge and non-abrasive car shampoo. Avoid high pressure washers (water jet can get under the trim and cause corrosion).
• 🌞 UV protection: apply UV protective wax (For example, Turtle Wax Ice Seal) 2 times a year.
• 🚗 Anti-gravel treatment: treat the rubber once a season anti-chip (For example, Liqui Moly Steinschlag-Schutz).
• ❄️ Winter care: Before the cold weather, lubricate the rubber seals with silicone grease to prevent them from becoming dull.

If small cracks appear on the lining, they can be temporarily “healed” using:

• Epoxy glue (For example, Poxipol) - for cracks up to 3 cm.
• Plastic welding - for major damage (a heat gun and an filler rod are required).
• Vinyl patches - if the crack is in a visible place and you need a quick solution.

Remember that any repair work to the trim is a temporary measure. In case of serious damage (cracks more than 5 cm long, through holes), it is better to immediately replace the part.

FAQ: answers to frequently asked questions

Is it possible to drive without a trunk liner?

Technically possible, but not advisable. The cover protects the metal cover from corrosion and also serves as a mount for the wiper and lock. Without it:

• Moisture and dirt will get into the trunk.
• The wiper will not work (if it is attached to the trim).
• Aerodynamics will deteriorate, which may affect fuel consumption.

If the pad is damaged but still holds, it is better to temporarily secure it with tape or zip ties than to drive without it at all.

What adhesive is suitable for repairing cracks in the trim?

For plastic covers Pathfinder R51 recommended:

• 3M Scotch-Weld DP8005 — two-component adhesive for plastic, withstands vibrations.
• Loctite Plastics Bonding System — a set with an activator for complex plastics.
• Adhesive-sealant SikaFlex-252 - if you need to seal a crack and waterproof it at the same time.

Be sure to degrease the surface before gluing. Antisilicon and clean it with sandpaper.

Where can I buy an original overlay cheaper?

Original overlay 90501-4M000 It's expensive, but you can save money:

• Order from Japan: on eBay or Buyee They often sell used originals in good condition (price ~8,000–12,000 RUR including delivery).
• Showdown: follow the announcements on Drom.ru or Avito (look for donors with mileage up to 100,000 km).
• Group orders: some owners clubs Pathfinder organize joint purchases of spare parts directly from dealers at a discount.

Beware of counterfeits of the original - check for the presence of a hologram Nissan and check the article number with the catalogue.

Do I need to paint the new trim if it matches the color?

Even if the overlay matches the color code, it often has to be touched up. Reasons:

• The new part looks brighter due to the lack of fading.
• Shades may vary due to different paint batches.
• Plastic and metal bodies perceive paint differently.

Recommendation: before installation, compare the trim with the body in daylight. If the difference is noticeable, order tinting to suit your needs. VIN (most car repair shops offer this service).

Is it possible to install a trim from another car?

Theoretically, it is possible to adapt linings from similar models, but this will require serious modifications. For example:

• Nissan X-Trail T31 — the shape is similar, but the fastenings do not match.
• Infiniti FX35 - wider and longer, trimming will be required.
• Renault Koleos - Fits true to size, but the locking cutout is different.

Such experiments are justified only if you could not find the original or an analogue. In other cases, it’s better not to take risks - an unsuitable trim can break the seal of the trunk.
