<em>Nissan Almera N16</em> rear shock absorber support: signs of malfunction, replacement and selection of the best analogues

Nissan Almera N16 is a popular sedan that is still actively used on the roads of the CIS. One of the weak points of the model is the rear suspension, namely shock absorber supports. Their wear leads to deterioration in handling, knocking in the cabin and uneven tire wear. In this article, we will look at how to diagnose a malfunction, which supports to choose for replacement, and how to carry out the work yourself - with nuances that are not written about in standard manuals.

Structurally, the rear shock absorber support is Almera N16 (body N16, 2000–2006) combines a rubber-metal hinge and an upper strut mount. It absorbs loads from the body, dampens vibrations and ensures correct suspension geometry. At the same time, the service life of the original supports rarely exceeds 80–100 thousand km - especially when driving on bad roads or with overload. Next, we’ll tell you what to look for when diagnosing and repairing.

Signs of a faulty rear shock absorber mount

The first symptoms of bearing wear are often confused with problems with the shock absorbers or springs themselves. However, there are specific signs that directly indicate a malfunction of the upper mount:

• 🔊 Knocking or squeaking in the area of the rear wheel arches when driving over uneven surfaces (even small ones). The sound often radiates into the cabin through the trunk.
• 🚗 Car withdrawal to the side when braking or accelerating - especially noticeable at speeds of 60–80 km/h.
• 🔄 Uneven rear tire wear along the inner or outer edge (provided that the wheel alignment is adjusted correctly).
• 💥 "Puncture" of the suspension on bumps - the shock absorber does not have time to work due to play in the support.

The problems are especially pronounced when fully loaded car or towing a trailer. If there are almost no knocks when the trunk is empty, but they appear when loading, there is a 90% chance that the supports are to blame. For an accurate diagnosis, it is enough to check the play of the strut at the top point by shaking it by hand with the wheel removed.

⚠️ Attention: On Almera N16 With a mileage of more than 150 thousand km, a knock in the rear suspension can be caused not only by the supports, but also by wear of the silent blocks of the trailing arms or cracks in the spring cups. Before replacing the supports, be sure to inspect these components!

Which rear shock absorber mounts are suitable for Nissan Almera N16

The market offers original spare parts and analogues from different manufacturers. It is important to consider that the supports for Almera N16 with engines QG15DE (1.5 l) and QG18DE (1.8 l) interchangeable — there is no difference in catalog numbers. However, there are some nuances with the configuration: some analogues are sold without a bearing, which will have to be replaced from the old part.

Manufacturer	Catalog number	Notes	Average price, rub.
Nissan (original)	54501-4M000	Set of 2 supports, with bearing	6 500–8 000
KYB (SM5098)	SM5098	High-quality analogue, bearing included	3 200–4 000
Monroe (904346)	904346	Without bearing, requires relocation	2 800–3 500
Sasic (2005022)	2005022	Budget option, resource ~50 thousand km	1 800–2 300
Febi (22630)	22630	Good price/quality ratio	3 500–4 200

When choosing supports, pay attention to rubber bushing material. Cheap analogues often use hard rubber, which quickly hardens in the cold and begins to creak. Original supports Nissan and high-quality analogues (KYB, Febi) have soft polyurethane inserts that retain elasticity longer.

Tools and preparation for replacing supports

To replace the rear shock absorber mounts with Almera N16 no specialized equipment required, but there are several mandatory conditions:

• 🔧 Reliable jack and safety stands (working on one jack is dangerous!).
• 🔩 Socket heads by 17, 19 and 21 mm (for unscrewing the rack mounting nuts).
• 🔨 Spring puller (if you plan to disassemble the rack completely).
• 🧴 WD-40 or equivalent — fastening nuts often stick.
• 🔥 Gas burner (optional) - will help warm up stuck threaded connections.

Before starting work necessarily:

1. Place the car on a flat surface and secure the front wheels with chocks.
2. Loosen the wheel nuts on the rear axle (but do not remove them completely!).
3. Open the trunk and remove the trim in the area where the pillars are attached (it is held on by plastic clips).

⚠️ Attention: On Almera N16 With ABS, the rear wheel speed sensors are attached to the struts. When removing the shock absorber don't pull the wire — disconnect the sensor connector in advance so as not to break the harness!

Step-by-step instructions for replacing the rear shock absorber mount

The process of replacing a support can be divided into two stages: dismantling the rack And disassembly/replacement of support. Let's look at both in detail.

1. Removing the rear pillar

Jack up the car on the desired side and remove the wheel. Next:

1. Unscrew the two bolts securing the shock absorber to lower arm (17 mm head).
2. In the trunk, unscrew the three nuts securing the support to the body (19 mm socket). Important: do not unscrew the central nut of the shock absorber rod at this stage - the strut may shoot out!
3. Carefully remove the strut and spring assembly through the wheel arch.

2. Disassembling the rack and replacing the support

To disassemble the stand you will need spring puller (or at least zip ties). Procedure:

1. Install the ties on the spring and compress it until play appears between the coils.
2. Unscrew the central nut of the shock absorber rod (21 mm head). Hold the rod with a 6mm wrench to prevent it from turning.
3. Remove the old support, bearing (if present) and rubber gaskets. Clean the seats from dirt.
4. Install the new support, observing the orientation (the arrow on the body should point forward in the direction of travel).
5. Tighten the shock absorber rod nut to torque 40–50 Nm.

When assembling the stand do not overtighten the stem nut - this may damage the shock absorber seal. After installing the stand in place, check that the spring fits into the grooves of the cup without distortion.

Common mistakes when replacing supports and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to premature failure of supports. Here are the most common:

• 🔧 Using a percussion instrument for unscrewing nuts. This distorts the threads and can damage the shock absorber rod.
• 🔄 Incorrect support orientation. If you install it backwards, the rubber will wear out faster due to uneven loads.
• 🧴 Lack of lubrication on rubber bushings. When assembling, apply a thin layer Litol-24 or CV joint-4 on contact surfaces.
• 🚗 Failure to check springs. If the spring has sagged or has cracks, the new support will last much less.

Another typical problem is insufficient tightening of the nuts securing the strut to the body. The tightening torque should be 35–45 Nm. If the nuts are not tightened enough, the support will “walk”, which will lead to knocking and accelerated wear of the rubber. If you overtighten, you can break the threads in the body.

What happens if you don't replace worn out supports?

Driving for a long time with damaged supports leads to:

1. Damage to shock absorbers — the rod begins to hit the upper bushing, which causes an oil leak.

2. Body deformations in places where the racks are attached (especially important for cars with rust).

3. Loss of controllability at high speeds - the car becomes “rolly” in turns.

4. Destruction of wheel bearings due to modified suspension geometry.

When is it necessary to replace supports, and when is repair sufficient?

The entire support does not always need to be changed. In some cases you can get by partial renovation:

• 🔧 If destroyed only rubber bushing, it can be replaced separately (catalog number 54529-4M000).
• 🌀 If the backlash gives support bearing, it is also sold separately (40520-4M000).
• 🛠️ If it’s cracked metal case supports - complete replacement only.

Repair is justified if the remaining elements of the support are in good condition. However, keep in mind that resource of repaired support will be 30–40% lower than a new one. For cars with mileage of more than 200 thousand km, it is better to install the original or a high-quality analogue (KYB, Febi).

When choosing between repair and replacement, focus on the condition of the suspension as a whole. If the shock absorbers are already “tired” (flowing, don’t hold the shock), and the springs have sagged, it is more advisable to change the strut assembly.

Cost of service work vs independent replacement

Prices for replacing rear shock absorber mounts Nissan Almera N16 services vary depending on the region:

Type of work	Cost, rub. (for 1 side)	Lead time
Replacing the support without removing the strut (if the shock absorber is working)	1 500–2 500	40–60 minutes
Replacing the support with removing the rack (complete disassembly)	2 500–3 500	1.5–2 hours
Replacement of supports assembled with shock absorbers	4 000–6 000	2–3 hours

Replacing it yourself will cost only the cost of spare parts. However, keep in mind that for work you will need:

• Spring puller (rent ~500 rub/day).
• A set of sockets and extensions (if you don’t have your own).
• Assistant (to hold the stand during assembly).

If you do not have experience working with suspension, it is better to entrust the replacement to professionals. Errors during assembly (for example, incorrectly tightened nuts or misaligned springs) can lead to emergency situation on the road.

FAQ: Frequently asked questions about rear shock absorber mounts Nissan Almera N16

Is it possible to drive with knocking supports?

Short-term - yes, but no more than 1-2 weeks. Driving for a long time with worn mounts leads to:

• Accelerated wear of shock absorbers (the rod hits the upper bushing).
• Deformations of the body in the places where the pillars are attached.
• Deterioration of controllability at high speeds.

If the knocking noise has appeared recently, check the tightness of the nuts securing the support to the body - sometimes they loosen over time.

How to check the support without removing the strut?

There are two ways:

1. Visual inspection: Open the trunk and inspect the rubber part of the support for cracks or peeling.
2. Checking the backlash: Rock the car up and down by the rear bumper. If you hear a knock or feel play, the support is worn out.

You can also ask an assistant to press the car fender down, mientras you listen to sounds from the trunk. Creaks or clicks will indicate a problem.

Which supports are better - original or KYB?

Comparison:

Criterion	Original (Nissan)	KYB (SM5098)
Resource	100–120 thousand km	80–100 thousand km
Price	6,500–8,000 per set	3,200–4,000 per set
Rubber quality	Soft, durable	Medium hard
Availability of bearing	Yes	Yes

Conclusion: The original will last longer, but KYB offers the best price/quality ratio. For cars with a mileage of up to 150 thousand km, you can safely take KYB.

Is it necessary to do a wheel alignment after replacing the bearings?

On Nissan Almera N16 replacing rear shock absorber mounts no effect on the wheel alignment angles, since they are not adjustable. However:

• If you changed springs or shock absorbers, check the height of the body - it should be the same on both sides.
• If before replacement the car was “pulled” to the side, check tire pressure And condition of silent blocks rear beam.

Rear wheel alignment Almera N16 it is not adjustable - it is fixed.

Is it possible to replace only one support?

Technically yes, but not recommended. The supports wear out approximately equally, and if one has become unusable, the second will soon fail. Besides:

• Different rigidity of the supports on the left and right impairs handling.
• When replacing one support, it may appear body roll to one side.

An exception is if the second support was replaced recently (less than 20 thousand km ago).
