Replacing the rear shock absorber mount on a Nissan Almera Classic: a complete guide with nuances

Nissan Almera Classic (also known as Nissan Sunny B10/N16 in some markets) is a reliable sedan, but with a mileage of over 150 thousand km, its suspension requires attention. One of the most common problems is wear rear shock absorber mounts, which are responsible for fixing the rack to the body and dampening vibrations. If, when driving over speed bumps or bumps, you hear a knock in the rear of the car, and upon inspection you see cracks in the rubber support bushings, it’s time to change them.

In this article we will analyze step-by-step replacement of the rear shock absorber mount on Almera Classic do it yourself: from fault diagnosis to assembly, taking into account typical errors. We will focus on unique nuances of the model, which are not described in standard manuals - for example, how to avoid damage to brake hoses during dismantling or why new supports can “creak” during the first 500 km.

Signs of a bad rear shock absorber mount

Shock absorber supports Nissan Almera Classic wear out gradually, and their failure is often disguised as other suspension problems. Here are the key symptoms that point specifically to supports:

• 🔊 Knocking or clicking noises in the rear when driving over bumps (even small ones). The sound is often confused with a strut failure, but if the shock absorber is fine, the strut is to blame.
• 🚗 Deterioration in handling at high speeds: the car begins to “drive” along the road, especially when braking or making sudden maneuvers.
• 🔧 Visible cracks or tears on the rubber part of the support (visible when the trunk lid is removed). If the rubber delaminates, the support no longer fulfills its function.
• 💧 Oil stains on the stand near the support (if the support is combined with the boot). This is a sign of damage to the seals.

On Almera Classic The rear supports are more likely to fail than the front ones due to the design features: they experience a greater load when loading the trunk. For example, if you often transport heavy loads, the service life of the supports is reduced by 30–40%. Also accelerates wear driving on broken roads And aggressive driving with hard braking.

⚠️ Attention! If you ignore the knocking of the supports, this will lead to play of the shock absorber strut, which can cause it to break through on a bump and lose control. At speeds over 80 km/h this is dangerous!

Which supports to choose for replacement: original vs analogues

On Nissan Almera Classic (body B10 or N16) shock absorber supports with catalog numbers were installed:

Part type	Original number	Analogs (brand + number)	Notes
Rear support (rubber+metal)	54501-4M000	Sasic 2005064, Febi 23630, Monroe 904346	The original is often counterfeited! Check the packaging for holograms.
Support with bearing	54501-4M010	SKF VKDA 35600, NSK B20-104	A bearing in the support reduces noise, but is 30–50% more expensive.
Boot + bumper	54520-4M000	Corteco 20016400, TRW JTC1342	It is recommended to change together with the support.

Original supports Nissan They last longer (lifespan ~100 thousand km), but their price is 2–3 times higher than their analogues. If your budget is limited, you can choose quality substitutes:

• 🔹 Sasic or Febi — optimal price/quality ratio. The rubber is softer than the original, but can withstand Russian roads.
• 🔹 Monroe or TRW — premium segment, close to the original in terms of resource, but 20–30% more expensive.
• 🔹 SKF/NSK (with bearing) - the best choice if there is play in the old support. Eliminates "creaking" when turning the steering wheel.

Check when purchasing complete set: Some supports come without mounting nuts or washers. Also note rubber color - for the original it is dark gray, for fakes it is often black or brown.

Tools and preparation for replacement

To replace the rear shock absorber mount with Almera Classic you will need:

• 🔧 Keys and sockets: slip-on 17 mm, end 10 mm, 12 mm, 14 mm, 19 mm (for the rod nut).
• 🔧 Special tools: spring ties (required!), ball joint remover (if you have to disconnect the lever).
• 🔧 Additionally: WD-40, torque wrench (for tightening with force 40–50 Nm), jack and stops.

Before starting work:

Disconnect the negative terminal of the battery (to avoid short circuit when working with electronics)

Clean threaded connections from dirt and treat with WD-40 1-2 hours before starting

Jack up the car and place jack stands under the front wheels.

Remove the rear wheel and trunk lid (to access the top mount)-->

Feature Almera Classic: The upper support mount is hidden under the trunk trim. To get to it you need:

1. Remove the plastic trim above the wheel arch (held on by 3 clips).
2. Unscrew the bolt securing the support to the body (head 14 mm).
3. Disconnect the ABS sensor connector (if it interferes).

⚠️ Attention! Do not proceed with work if the spring ties are weak or damaged. On Almera Classic The rear suspension springs have a high compression force - if the tie comes off, you can get seriously injured!

Step-by-step instructions for replacing the rear support

The process of replacing the support Nissan Almera Classic takes 2–3 hours per side. Let's look at it step by step:

1. Dismantling the old support

First remove the shock absorber assembly:

1. Unscrew the lower fastening of the strut to the lever (nut 17 mm + bolt 14 mm).
2. Disconnect the brake hose from the bracket on the rack (carefully so as not to damage it!).
3. Remove the top nut of the shock absorber rod (you will need to hold the rod with a wrench 6 mm through the hole in the support).
4. Remove the strut along with the spring.

Now disassemble the rack:

1. Place the clamps on the spring and compress it until the support is released.
2. Unscrew the shock absorber rod nut (head 19 mm) and remove the old support.

2. Installation of a new support

Before assembly, check:

• 🔍 Condition boot and bumper - if they are torn, replace them.
• 🔍 Shock absorber rod for corrosion or scoring (clean if necessary).
• 🔍 Spring for cracks or deformation.

Assembly occurs in reverse order:

1. Install the new support onto the shock absorber rod and secure with a nut (do not tighten!).
2. Place the spring on the support, aligning its ends with the seats.
3. Slowly loosen the ties while monitoring the position of the spring.
4. Tighten the rod nut to torque 40–50 Nm.

3. Installing the rack on the car

When installing the rack back:

• 🔧 First, secure the upper mount of the support to the body (bolt 14 mm, moment 35 Nm).
• 🔧 Then the lower mount to the lever (nut 17 mm, moment 80–100 Nm).
• 🔧 Connect the brake hose and ABS sensor (if disconnected).

Common mistakes and how to avoid them

When replacing the rear supports with Nissan Almera Classic Car owners often make mistakes that lead to repeated repairs. Here are the most common:

1. Incorrect tightening of nuts. If you tighten the shock absorber rod nut (over 50 Nm), the support will deform and a squeak will appear. If you don't tighten it enough, there will be a backlash.
2. Ignoring the anther. Many people only change the support, forgetting about the boot and bump stop. This leads to dirt getting into the shock absorber and its premature failure.
3. Damage to the brake hose. When dismantling the stand, the hose is often bent or pulled - this can cause it to rupture. Always remove the hose from the bracket carefully!
4. Incompatible parts. Supports from Nissan Primera P12 They are similar in appearance, but have a different seat diameter. Install them on Almera Classic you can't!

Another common problem is "creaking" of new supports in the first 500–1000 km. This is normal: the rubber “grinds” to the metal. If the squeak does not disappear after 1000 km, check:

• 🔧 Correct installation (perhaps the support is skewed).
• 🔧 Quality of spare parts (cheap analogues often squeak due to hard rubber).
• 🔧 The condition of the boot (if it rubs against the spring, there will be an extraneous sound).

What should I do if the knocking noise remains after replacing the support?

If the knocking noise persists, check:

1. **State of the shock absorber** - it may be “broken” and requires replacement.

2. **Back in the silent blocks of the lever** - on Almera Classic they often wear out at the same time as the supports.

3. **Attaching the stabilizer link** - loose nuts give a similar knocking noise.

4. **Spring condition** - cracks or subsidence cause impacts on the support.

When to call for service and when to handle it yourself

Replacing the rear shock absorber mount with Nissan Almera Classic you can do it yourself if you have:

• 🔧 Experience with spring ties (or an assistant who knows how to use them).
• 🔧 Complete set of tools including torque wrench.
• 🔧 Possibility to leave the car for 1-2 days (in case something goes wrong).

You should contact the service in the following cases:

• 🚗 If the support is “stuck” to the body and the bolts cannot be unscrewed (a welding machine or grinder will be required).
• 🚗 If you need to change the shock absorber or spring along with the support (the work is more difficult and requires special tools).
• 🚗 If after replacement there is still a knock or a pull to the side (diagnostics of the suspension on a stand is needed).

Average cost of replacing a rear support in the service:

Type of work	Cost (for 1 side), ₽
Replacing the support (without removing the rack)	1 500 – 2 500
Replacing the support with removing the rack	3 000 – 4 500
Replacement of support + shock absorber	5 000 – 7 000

If you decide to do the work yourself, be patient: you can spend up to 4 hours on the first support, and 2 times faster on the second.

FAQ: Frequently asked questions about replacing supports on Almera Classic

Is it possible to drive with a broken rear shock absorber mount?

Short-term (up to 1–2 weeks) is possible, but with caution: avoid high speeds and sudden maneuvers. Driving for a long time with a faulty support leads to:

• 🔧 Accelerated wear of the shock absorber (due to play).
• 🔧 Damage to the spring (it may jump out of its seat).
• 🔧 Deterioration of braking distance (due to violation of suspension geometry).

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

On Nissan Almera Classic rear suspension - multi-link, and support replacement no effect on the wheel alignment angles. However, if you disconnected the levers or balls when dismantling the strut, the camber may be lost. Check:

• 🔧 Uniform tire wear (if one side wears out faster, camber is needed).
• 🔧 Car behavior on a straight line (if it pulls to the side, check the toe-in).

In 80% of cases, after replacing the supports, camber is not required.

How long do the rear supports last on the Almera Classic?

The resource depends on the operating conditions:

• 🚗 Original supports: 80–120 thousand km.
• 🚗 High-quality analogues (Sasic, Febi): 60–90 thousand km.
• 🚗 Budget supports: 30–50 thousand km.

Factors that reduce service life:

• 🔧 Frequent off-road driving.
• 🔧 Vehicle overload (for example, towing a trailer).
• 🔧 Aggressive driving with sudden braking.

Is it possible to replace only the rubber part of the support without changing the metal part?

Technically yes, but not recommended. Rubber bushing is sold separately (eg. 54501-4M001), but:

• 🔧 The metal part of the support will deform over time, and the new rubber will not fit tightly.
• 🔧 The bearing (if it is in the support) wears out along with the rubber - you cannot change it separately.
• 🔧 Savings of 500-1000 ₽ are not justified: after 20-30 thousand km the tires will break again.

What is the difference between the supports for Almera Classic (B10) and Almera N16?

Although both models are similar in appearance, the supports not interchangeable:

Model	Support catalog number	Features
Almera Classic (B10)	54501-4M000	The diameter of the seat is 52 mm, the height of the support is 60 mm.
Almera (N16)	54501-4M200	Diameter - 55 mm, height - 65 mm. Not suitable for B10!

Installation of support from N16 on Classic will lead to:

• 🔧 Incorrect operation of the shock absorber (handling will worsen).
• 🔧 Rapid wear of the rubber bushing due to size mismatch.
