Nissan Sunny is a legendary car that, despite its age, remains popular due to its reliability and simplicity of design. However, over time, even the toughest nodes require attention, and rear pillars (shock absorbers) are no exception. Worn shock absorbers not only impair comfort, but also directly affect safety: braking distance increases, the car “steals” on uneven surfaces, and during sharp maneuvers, loss of control is possible.
In this article we will look at everything you need to know about rear struts. Nissan Sunny: from signs of malfunction to step-by-step instructions for replacement. We analyzed owner reviews, technical characteristics of original and analog parts, as well as typical installation errors. We will pay special attention to models N14, N15 And N16 - the most common on the Russian market.
Signs of wear on the rear struts on a Nissan Sunny
The first symptoms of shock absorber problems often go unnoticed, especially if wear occurs gradually. However there is key signalsthat should alert you:
- 🔴 Increased body roll when cornering, the car “leans” to one side more than usual.
- 🔴 "Sagging" of the rear when loading the trunk or passengers (the racks do not support the weight).
- 🔴 Knocking or squeaking from the rear suspension on uneven surfaces (may indicate destruction of bushings or oil leakage).
- 🔴 Body "bouncing" after driving over bumps, the shock absorbers do not dampen vibrations.
- 🔴 Uneven rear tire wear (especially along the inner or outer edge).
It is important to distinguish strut wear from problems with springs or stabilizer bushings. For example, if the car “sags” even without a load, the springs are most likely to blame. And if you hear a metallic knock when the body rocks, check the strut fastenings or support bearings.
⚠️ Attention! On Nissan Sunny N16 (2000–2006) a common problem with corrosion of rack mounts to the body. If the bolts are stuck, attempting to remove them without first treating them with WD-40 or a similar product may cause the threads to break.
- Once every 10,000 km
- Once a year
- Only when knocking occurs
- Never
Which racks are suitable for Nissan Sunny: original vs analogues
Original rear struts for Sunny are produced under the brand Nissan (item depends on generation). However, their price is often steep - from 8,000 to 15,000 rubles apiece. Alternative - high-quality analogues, which, if chosen correctly, serve no worse.
| Generation | Original article | Popular analogues (brand + article) | Average price, ₽ |
|---|---|---|---|
| N14 (1991–1998) | 54300-4M000 | Kayaba 343220 / Monroe G5438 | 3 500–5 000 |
| N15 (1998–2000) | 54300-6M000 | Sachs 315 191 / Bilstein 19-185367 | 4 000–6 500 |
| N16 (2000–2006) | 54300-9M000 | TOKICO 33283 / Febi 23136 | 4 500–7 000 |
When choosing analogues, pay attention to:
- 🔧 Shock absorber type: for Sunny only suitable oil or gas-oil racks. Gas (for example, KYB Excel-G) are stiffer and suitable for a sporty driving style.
- 🔧 Presence of anther: some cheap analogues are sold without it, which shortens the service life.
- 🔧 Country of manufacture: racks from Japan or Europe (eg Bilstein, Sachs) are more durable than Chinese ones.
Before purchasing, check if new ones are included mounting bushings And nuts. Many analogues do not have them, and old parts often require replacement due to wear or corrosion.
Step-by-step instructions for replacing rear struts
Replacing rear shock absorbers with Nissan Sunny - a task of medium complexity. If you have tools and an inspection hole (or a lift), even a beginner can handle it. The main thing is to be consistent and take your time.

Step 1: Removing the old rack
1. Open the trunk and remove the plastic plugs covering the upper mounts of the struts (on N16 they are fixed with clips).
2. Unscrew the top nut securing the strut to the body (you will need a head on 17 mm and extension cord). Do not remove it completely - just loosen it, otherwise the stand may rotate.
3. Raise the car on a jack, remove the rear wheel and close it under the threshold (for safety).
4. Unscrew the lower bolt securing the strut to the lever (head on 14 mm). This is where rust often causes problems - if the bolt won't budge, use penetrating lubricant and a hammer to lightly tap the wrench.
Step 2: Install the new rack
1. Remove the old strut along with the spring (if the spring remains in place, carefully compress it with special ties).
2. Transfer all rubber elements from the old rack to the new one: boot, bumper And bushings (if they are not included).
3. Install the new stand into place, starting with the bottom mount. Tighten the bolts only after the car is lowered onto the wheels (otherwise the suspension will remain under tension).
4. Tighten the top nut firmly 40–50 Nm (use a torque wrench).
⚠️ Attention! On Nissan Sunny N14 With ABS, the rear wheel speed sensor is mounted to the strut. When dismantling, carefully disconnect the connector so as not to damage the wiring!
What to do if the stand cannot be removed?
If the post is stuck to the lever, try the following:
1. Spray the joint with WD-40 and wait 10-15 minutes.
2. Using light blows of a hammer through a wooden spacer, tap on the ear of the lever.
3. Use a ball joint puller (if the strut is stuck in the seat).
4. As a last resort, cut the bolt with a grinder (but then you will need new fasteners).
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that later lead to premature failure of the struts or deterioration of controllability. Here are the most common:
- ❌ Incorrect bolt tightening — if you overtighten the lower mount, the rubber bushings will quickly collapse. If you don’t tighten it enough, the stand will “walk.”
- ❌ Ignoring anthers — without protection, the shock absorber rod quickly becomes corroded and the seal wears out.
- ❌ Installing racks without bleeding — if the shock absorber is not pumped before installation (especially the oil one), it will not work effectively.
- ❌ Replacing only one rack — even if the second one is “still alive,” the difference in stiffness will lead to an imbalance in the suspension.
Another common problem is incompatibility of springs and struts. For example, if you installed sports shock absorbers (for example, KYB AGX), and the springs are left standard, the suspension will be too stiff, which will lead to accelerated wear of the remaining elements.
After replacing the racks, be sure to check wheel alignment rear wheels. Even small changes in suspension geometry can cause uneven tire wear.
How to extend the life of your rear struts
The average life of the rear shock absorbers is Nissan Sunny - 80,000–120,000 km, but with proper operation this period can be increased by 30–50%. Here's what really works:
- 🛠️ Avoid overload — maximum load on the rear axle Sunny should not exceed
350–400 kg(depending on model). - 🛠️ Wash your pendant in winter — salt and reagents corrode the anthers and fastenings. It is enough to wash the racks with water under pressure once a month.
- 🛠️ Check the condition of the bushings — worn rubber bushings increase the load on the shock absorber.
- 🛠️ Don't ignore small knocks - even a faint sound may indicate the beginning of an oil leak from the rack.
If you frequently drive on dirt roads or potholes, consider installing reinforced shock absorbers (For example, TOKICO Illumina or Bilstein B4). They are more expensive, but cope better with loads.
Brand comparison: which struts are best for Nissan Sunny
The choice of shock absorbers is always a compromise between price, quality and performance. We tested several popular brands on Nissan Sunny N16 and made the ratings:
| Brand | Model | Type | Hardness (1–10) | Service life (thousand km) | Price per piece, ₽ |
|---|---|---|---|---|---|
| Kayaba (KYB) | Excel-G | Gas-oil | 7 | 100–120 | 4 500 |
| Monroe | Reflex | Oily | 5 | 80–100 | 3 800 |
| Bilstein | B4 | Gas-oil | 8 | 120–150 | 6 200 |
| Sachs | Super Touring | Oily | 6 | 90–110 | 5 000 |
For urban use optimal Monroe Reflex or Sachs Super Touring - they are softer and more comfortable. For aggressive driving or bad roads it is better KYB Excel-G or Bilstein B4.
Beware of cheap Chinese brands (eg. Febi or TRW in the budget segment) - their resource rarely exceeds 50,000 km, and the characteristics often do not correspond to the declared ones.
FAQ: Frequently asked questions about Nissan Sunny rear struts
Is it possible to drive if one strut is leaking and the other is intact?
Technically possible, but highly undesirable. Different shock absorber stiffness leads to:
- uneven tire wear;
- deterioration in controllability (the car “steers” to the side);
- increasing braking distance.
If the strut is leaking heavily (oil drips onto the asphalt), replace it as soon as possible - this is a safety issue.
Do I need to change the springs along with the struts?
Not necessary if the springs:
- have no cracks or deformations;
- did not sag (measure the height of the suspension - it should be the same on both sides);
- did not corrode (especially in places where they rest on the cups).
However, if the springs last more than 150,000 km, replacing them along with the struts will extend the life of the suspension.
How to bleed a rack before installation?
Bleeding is needed to remove air from the working chamber of the shock absorber. Instructions:
- Turn the rack upside down.
- Squeeze it smoothly until it stops (3-5 times).
- Hold the squeeze for 2-3 seconds, then release slowly.
- Repeat 3-4 times until the stroke becomes smooth.
After bleeding, the stand must be installed within 15 minutes, otherwise air may get inside again.
What is the difference between Sunny stands with and without ABS?
On models with ABS (For example, N16 2002–2006) the rack has a mount for wheel speed sensor. If you install a strut without a hole for the sensor, the ABS system will generate an error, and in some cases it will fail completely.
When purchasing, check with the seller whether the rack is suitable for your modification (with or without ABS).
Is it possible to restore old racks?
Theoretically yes - some workshops offer shock absorber rebuild (replacing seals, adding oil). However:
- the cost of restoration is often comparable to the price of a new shock absorber;
- the quality of work depends on the qualifications of the master;
- There is usually no warranty on refurbished racks.
For Nissan Sunny restoration is only practical for rare or expensive original racks (for example, for Sunny GTi-R).
