You will also find step-by-step replacement instructions, anti-corrosion treatment tips and answers to frequently asked questions.
Why are rear fenders needed? Nissan X-Trail T31?
Rear fenders are not just a decorative element, but an important part of body protection. They perform several key functions:
- 🛡️ Protection from dirt and moisture: prevent water, sand and reagents from entering the metal elements of arches and thresholds, which reduces the risk of corrosion.
- 🚗 Reduced suspension wear: reduce the amount of abrasive particles falling on shock absorbers and springs.
- 🔧 Preservation of paintwork: protect the paint on the arches from chipping when hit by stones or gravel.
- 💨 Aerodynamics: Properly installed fender liners improve streamlining, reducing noise and fuel consumption.
On X-Trail T31 rear fender liners are especially vulnerable due to their design features: they are mounted in an area where moisture accumulates, and when driving off-road they are subject to impacts from branches and stones. If you ignore their condition, the consequences can be serious - from rust on the arches to damage to the brake hoses.

Step by step instructions:
- Removing the old fender liner:
Unscrew the fastening bolts around the perimeter of the arch (usually 4-6 pieces) and plastic clips. Be careful - some clips may break during removal. If the fender liner is stuck, use WD-40.
- Cleaning and preparation:
Remove rust from the arch with a metal brush, treat problem areas with a rust converter (for example, Tsinkar). Apply an anti-corrosion compound (eg Movil or Dinitrol).
- Installing a new fender liner:
Try on the part and adjust to size if necessary. Attach the bolts and clips starting from the top. Use sealant on joints to prevent moisture from entering.
- Check:
Make sure that the wheel arch liner does not touch the wheel when rotating. Take it for a test drive and listen for any outside noise.
If the fastening clips are broken, replace them with new ones (part number 90510-4M000 for X-Trail T31). Use clips with a metal core - they are more reliable than plastic ones.
Typical mistakes when replacing fender liners and how to avoid them
Even experienced car owners sometimes make mistakes that lead to rapid failure of the wheel arch liners. Here are the most common:
- Incomplete cleaning of the arch from rust:
If you leave pockets of corrosion under the new fender liner, the process will continue to develop, and in a year or two you will have to repeat the work. Use rust converter and anti-corrosion mastic even on small stains.
- Poor fixation of clips:
Loosely secured clips fly out over time, and the fender liner begins to dangle. Just one lost clip can cause a part to come off on the fly.
- Ignoring sealing:
Without sealant, moisture will penetrate between the fender liner and the body, which will accelerate corrosion. Use silicone sealant or specialized formulations (for example, 3M 08597).
- Wrong size selection:
Universal fender liners often require trimming. If this is not done in advance, the part will interfere with the rotation of the wheel or rub against it.
⚠️ Attention! After replacing the wheel arch liners, check the operation of the rear brakes. Sometimes inaccurate installation can lead to chafing of the brake hoses or handbrake cable. Inspect them for damage!
Anti-corrosion treatment: how to extend the life of fender liners?
Even the highest quality fender liners will last longer if you care for them properly. Here are the key events:
- 🧼 Regular washing: Once every 2-3 months, clean the wheel arch liners from dirt and salt deposits. Use Kercher or a pressure washer, but keep the nozzle 30–40 cm away to avoid damaging the plastic.
- 🛡️ Application of protective compounds: Treat the fender liners 1–2 times a year anti-gravel or wax compounds (for example, Turtle Wax). This creates a protective film that repels moisture.
- 🔧 Checking fasteners: After winter, inspect the clips and bolts. If necessary, tighten them or replace them with new ones.
- 🚗 Careful off-road driving: Avoid hitting branches or rocks hard. If the fender liner is bent, it is better to straighten it or replace it immediately.
For additional protection, you can install mud flaps (article 69410-4M000 for X-Trail T31). They will reduce the amount of dirt that gets on the fender liners and extend their service life by 20–30%.
Why is fender liner corrosion dangerous?
If you ignore rust on the fender liners, it will spread to the arches and sills. In advanced cases, this leads to through corrosion, which requires welding. For example, replacing the rear arch with X-Trail T31 costs 15,000–25,000 rubles, and a complete restoration of the threshold costs up to 40,000 rubles. Regular inspection and anticorrosive treatment are several times cheaper!

FAQ: Frequently asked questions about rear fender liners Nissan X-Trail T31
Is it possible to drive without rear fenders?
Technically possible, but not advisable. Without wheel arch liners, dirt and moisture will actively fall on the metal of the arches and suspension, accelerating corrosion. The noise in the cabin will also increase when driving on wet roads.
What sealant is best to use during installation?
Optimal options:
- Silikon-Fett (from Liqui Moly) - does not freeze in winter, is resistant to detergents.
- 3M 08597 — professional sealant for cars, does not flow when heated.
- Abro (silicone) - a budget option, but requires updating once a year.
How long do the fender liners last on the X-Trail T31?
Service life depends on the material and operating conditions:
- Original: 5–7 years.
- High-quality analogues (Febi, Sidem): 3–5 years.
- Universal rubber: 1–2 years.
With aggressive off-road driving or lack of maintenance, the period is reduced by 1.5–2 times.
What to do if the fender liner rubs against the wheel?
Causes and solutions:
- Incorrect installation: Adjust the fender liner to size or reinstall.
- Arch deformation: Check the geometry after an accident or a strong impact.
- Suspension wear: Replace shock absorbers or springs if the wheel is misaligned.
The problem cannot be ignored - friction can lead to damage to the tire or breakage of the fasteners.
Is it possible to paint the fender liners?
Yes, but only with special paint for plastic (for example, Motip Plastik or Krylon Fusion). Pre-clean the surface from grease and treat it with an adhesive primer. The paint will extend the life of the fender liner and improve its appearance.
