Front rear wheel mudguard Nissan Qashqai J10 (2007–2013) - a detail that many owners underestimate until they are faced with corrosion of thresholds or constant contamination of doors. This plastic or rubber element protects the body from sand, water and road chemicals, but over time it wears out, cracks or comes loose. Unlike the mudguards of the front wheels, the rear ones are often ignored during inspection, although their damage leads to much more serious consequences - including rotting of the side members.

In this article we will look at how to choose the right mudguard according to the article numbers, which analogues are better suited than the original, and step by step We will show you the replacement process with photos and videos. We will also reveal secret life hack for restoring fasteners without drilling a new hole - this will save you time and nerves. If you have already encountered the problem of a falling mudguard or are just planning preventive maintenance, read on.

Why do you need a front rear wheel mudguard? Qashqai J10?

At first glance, a mudguard is just a piece of plastic that prevents dirt from flying onto the door. But in fact, its functions are much broader:

• 🛡️ Corrosion protection: Without a splash guard, water and salt from the road get onto the sills and the bottom of the door, accelerating rusting by 3-5 times.
• 🚗 Reduced paintwork wear: sand and small stones flying out from under the wheels scratch the paint, which leads to chips and further rotting of the metal.
• 🔧 Preventing drain clogging: in the wheel arches Qashqai J10 There are drainage holes that, without a mudguard, quickly become clogged with dirt.
• 💨 Improved aerodynamics: A properly installed mudguard reduces air turbulence in the wheel arch, which slightly reduces noise at speed.

On Nissan Qashqai J10 The front rear wheel mudguard is especially important due to its design feature: the rear arch has an open bottom, and without protection, dirt flies directly onto threshold and lower part of the rear door. Owners who remove mudguards “for beauty” are faced with rust on the body welds after 2–3 years.

⚠️ Attention: If you notice that after rain moisture appears under the feet of rear seat passengers, there is a 90% chance that the problem is a missing or damaged mudguard. Water penetrates through the technological holes in the arch and accumulates under the mat.

Original articles and analogues: what to choose?

For Nissan Qashqai J10 (including restyling 2010) the front rear wheel mudguard has the following original part numbers:

Side	Original article	Price (guideline, rub.)	The best analogues
Left (driver's side)	77110-4M00A	2 800–3 500	Febi 33630, Mega 771104M00A
Right (passenger side)	77110-4M00B	2 800–3 500	Sasic 2301011, Hans Pries 810101
Set (left + right)	77110-4M00C (packaging)	5 000–6 000	Ruville 612301 (set)

Original mud flaps from Nissan They are made of durable plastic with rubber inserts, but their main disadvantage is their high price. Analogues are 30–50% cheaper, but here it is important to pay attention to:

• 🔍 Material: high-quality analogues (for example, Febi or Ruville) use the same plastic as the original. Cheap Chinese options crack within a year.
• 📏 Fit accuracy: some analogues (for example, Sasic) may have slight deviations in the fastenings - you will have to modify them with a drill.
• 🛠️ Complete set: The original comes with all the clips and bolts, but analogues often have to buy them separately.

If you are choosing between the original and the analogue, focus on service life: original mudguards last 5–7 years, and good analogues last 3–4 years. For Qashqai J10 with a mileage of over 150 thousand km, it makes sense to take analogues, since the body may already have hidden corrosion, and in a few years a complete replacement of the arches will be required.

Step-by-step instructions for replacing the mudguard

Replacing the front rear wheel mudguard with Nissan Qashqai J10 does not require special skills, but there are several nuances that will simplify the process. You will need:

• 🔧 Socket set (10 mm, 12 mm)
• 🔨 Plastic spatula for removing clips
• 🧲 Magnet for bolts (so as not to lose in the arch)
• 🧴 WD-40 or similar cleaner (if bolts are rusty)

Step 1. Preparation

Raise the car on a jack or drive it into a viewing hole. Remove the rear wheel - this will give full access to the mudguard. Clean the arch from dirt so as not to bring it into the interior during operation.

Step 2. Removing the old mudguard

The mudguard is attached with 3–4 bolts (depending on the year of manufacture) and 2–3 plastic clips. Unscrew the bolts with a 10 mm socket and carefully pry off the clips with a plastic spatula. Do not pull the mudguard by force - it may break, leaving pieces of plastic in the fasteners.

Step 3. Installing a new mudguard

Try on the new part to the arch. If the holes do not match (this is true for some analogues), carefully drill them out with a drill. Secure the mudguard with the bolts, but do not tighten them all the way - snap the clips first. Only then tighten the bolts completely.

Step 4. Check

Make sure that the mudguard fits snugly against the arch and is not loose. Spray the wheel with water from a hose - if the water does not reach the threshold, the installation was successful.

Typical replacement mistakes and how to avoid them

Even such a simple operation as replacing a mudguard is fraught with pitfalls. Here are the most common mistakes and their consequences:

1. Ignoring rust on the arch. If you don't clean the metal before installing a new mudguard, corrosion will continue to spread underneath the plastic. After a year you will have to remove the part again.
2. Tightening the bolts. The plastic of the mudguard may crack, and the threads in the arch may break. Tighten the bolts with a force of no more than 5 Nm.
3. Using the wrong clips. Clips from front mudguards or other models Nissan do not fit - they either do not lock in place or break during installation.
4. Forget about drainage holes. If they are clogged, water will accumulate in the arch, accelerating corrosion. Before installing the mudguard, clean them with wire.

⚠️ Attention: If after replacing the mudguard you hear a whistle at speeds above 80 km/h, most likely the part is not installed tightly and is creating turbulence. Double-check the fastenings and apply sealing tape if necessary.

Another common problem is lack of sound insulation. On Qashqai J10 From the factory, a thin layer of mastic is laid between the mudguard and the arch. If it is not restored, noise from stones hitting the plastic will be heard in the cabin. Suitable for these purposes sheet sound insulation 2–3 mm thick.

How to restore the mudguard mounts without drilling?

Over time, the plastic clips break and the holes in the arch wear out. Many people drill new holes in this case, but this weakens the body. We'll tell you how to do without it.

Method 1: Repair clips

Buy repair clips with a larger diameter (for example, 3M 08577). They have a rubber bushing that compensates for the enlarged hole. Installation takes 2 minutes:

1. Insert the clip into the hole.
2. Press until you hear a click.
3. Attach the mudguard.

Method 2: Epoxy resin + pin

If the hole is so loose that the clip does not hold:

1. Clean the hole from dirt and degrease.
2. Apply epoxy around the edges.
3. Insert a metal stud with M6 thread.
4. After drying (24 hours), screw the mudguard with a nut.

What to do if the mudguard is cracked and you don’t have a new one at hand?

If the mudguard is cracked but still holding up, it can be temporarily repaired using:

1. Plastic welding (use a soldering iron and a plastic rod).

2. Epoxy adhesive with reinforcement (stick fiberglass on the back side).

3. Stainless steel clamps (if the crack is on the edge).

Such repairs will last 1-2 seasons, but do not replace a complete replacement of the part.
