Many owners Nissan Almera Classic Over time, they begin to notice an unpleasant knocking sound in the steering column, which is especially noticeable when driving over bumps or making sharp turns. Often the problem lies not in the steering mechanism itself, but in the crosspiece of the steering cardan, which is a consumable item and has a limited resource. Ignoring this malfunction can lead to play in the steering wheel and even loss of control in a critical situation.
Replacement process steering cardan does not require highly complex equipment, but involves working under the car and in cramped conditions in the engine compartment. If you have basic plumbing skills and a set of tools, you can perform this procedure yourself, saving a significant amount on service costs.
In this article, we will analyze in detail the reasons for the failure of a part, the criteria for choosing a new spare part, and provide step-by-step instructions for dismantling and installation. We will pay special attention to the subtleties of fixing the bolts and the correct choice of lubricant for long-term operation of the unit.
Diagnosis of faults and signs of wear
The main symptom of wear on the steering universal joint is a characteristic metallic knock that is transmitted to the steering wheel. This sound usually occurs when driving on uneven roads when the wheels hit obstacles. In some cases, the knocking noise may be accompanied by vibration of the steering wheel at low speeds.
In addition to sound manifestations, the driver may notice the appearance of free play in the steering wheel. If you turn the steering wheel and the wheels are delayed in their response or there is a feeling of emptiness when the steering wheel begins to move, this is a sure sign that driveshaft play exceeded permissible limits. In advanced cases, sharp rotation may cause a feeling of sticking or “jumping.”
For an accurate diagnosis, it is necessary to raise the front of the car on a lift or jacks. Have a helper rock the steering wheel from side to side while you observe the steering gear and shaft. You will immediately see at what point free movement occurs: on the crosspiece or in the gearbox itself. If play is observed precisely at the junction of the shafts, replace steering cardan inevitable.
Selecting quality spare parts and necessary tools
The auto parts market offers many options for steering cardans for Nissan Almera Classic, but their quality varies greatly. The original part from Nissan is distinguished by high manufacturing precision and reliability, but is much more expensive than its analogues. Among the popular replacement brands, it is worth paying attention to specialized suspension manufacturers, such as GMB or Ruville.
- 🔧 Original part number to check compatibility: 48520-AX00A
- 💰 Analogue options are often cheaper, but require careful inspection of the packaging and the absence of play on the counter
- ⚙️ Avoid buying universal joints without markings and at a suspiciously low price, as they may fall apart after a couple of thousand kilometers
To perform the work, you will need a standard set of tools that most car enthusiasts have. The main working element will be a 12 or 14 mm wrench, since the crosspiece mounting bolts are Nissan Almera They are exactly the same size. You will also need a wrench, extensions and, possibly, a 17 mm socket for the nut securing the cardan itself to the steering rack.
Be sure to use a penetrating lubricant (such as WD-40 or similar) as bolts often stick to the metal due to corrosion and dirt. If the thread is soured, it will be extremely difficult to unscrew the fastener without pre-treatment, which can lead to the bolt head breaking off. A hammer and drift will also be useful for knocking out the old shaft.
⚠️ Attention: Never use a gas wrench to unscrew the crosspiece mounting bolts, as this can damage the edges and make the part unsuitable for further use if you decide to replace it with a new one.

Preparing the car for repair work
Before starting work, it is necessary to ensure a safe position of the vehicle. Place the car on a level surface, apply the handbrake and chock the rear wheels. If you are working in a hole, make sure it is deep enough to allow free movement underneath. When working on jacks, be sure to use safety stands.
Open the hood and unscrew the bolts securing the steering shaft to the steering rack. It is more convenient to do this from above, after first removing the plastic boot, if any. On Nissan Almera Classic Access to the top of the driveshaft may be limited, so sometimes you have to remove some of the engine compartment trim for convenience.
The next step is to remove the bottom mount. Sit under the car and find the place where the driveshaft connects to the steering gear. Clean the connection area from dirt and generously treat the mounting bolts with penetrating lubricant. Let the product sit for 10-15 minutes to allow it to penetrate the threads and rust.
If you plan to remove the entire steering shaft, make sure the steering wheel is locked in a straight position.
☑️ Preparing to replace the driveshaft
The process of dismantling the old driveshaft
We start directly with dismantling. Take a 12 or 14 mm wrench and start unscrewing the crosspiece bolts. On Nissan Almera Classic usually hex or socket head bolts are used, depending on the year of manufacture. If the bolts do not budge, use an extension and add force gradually so as not to break the tool.
After the bolts are unscrewed, you need to separate the shafts. Sometimes they sit very tightly, and you have to carefully beat them off. Use a hammer and drift made of soft metal or wood to avoid damaging the friction surfaces. When striking, try to hit the end of the shaft, and not the crosspiece, so as not to completely destroy it.
- 🔨 If the shaft does not budge, try rocking it from side to side while striking the end
- 🛠️ In some cases, it is necessary to use a tie rod puller if the connection is too tight
- ⚙️ Make sure that the shaft does not fall on the suspension parts, as this may damage them
After dismantling the lower part, move on to the upper. Unscrew the bolts in the engine compartment and carefully remove the entire assembly. If the cardan consists of two parts connected by a cross, you can remove only the cross, but this is more difficult and less reliable. It is better to change the entire assembly to guarantee quality.
⚠️ Attention: When removing the shaft, carefully inspect the condition of the spline connection. If the splines show signs of heavy wear or chips, this may be the cause of the knocking noise even after replacing the spider.
What to do if the bolts are broken?
If the edges of the bolt are torn off, you can try to unscrew them using an extractor or carefully drill them out. As a last resort, you will have to cut the bolt with a grinder and then cut a new thread, but this is an extreme measure that requires high precision.
Installation of a new part and final assembly
Installing a new steering cardan starts with fitting. Check whether the splines of the new shaft match the steering column shaft and rack. Insert the shaft into place, making sure it fits snugly and without play. If the splines are new, they may fit in with force - this is normal.
Then proceed to tighten the bolts. Use new bolts if they were included, as old ones may be deformed. Tighten the bolts in a criss-cross pattern to ensure even flange seating. The tightening torque should be sufficient, but not excessive, so as not to strip the thread.
After installing all bolts, be sure to carry out a control check. Rock the steering wheel from side to side and check for knocks or play at the connection point. Make sure that the shaft rotates freely and does not interfere with body parts or other suspension components.
At this stage, you can install the protective cover (boot) if it has been removed. The boot protects the mechanism from moisture and dirt, which extends the service life of the crosspiece. Secure it with clamps, ensuring a tight fit on both sides.
Proper tightening of the bolts and the absence of play is a guarantee of safety when driving, so do not neglect the final check.
Quality criteria and maintenance
In order for the new part to last for a long time, it is important to follow the operating instructions. Regularly check the condition of the steering mechanism and driveshaft, especially after off-road driving or on bad roads. Any extraneous sounds should be a reason for immediate diagnosis.
| Parameter | Value for Nissan Almera Classic | Recommendation |
|---|---|---|
| Mounting type | Bolted connection | Use bolts of strength class 8.8 and higher |
| Shaft diameter | 20-25 mm | Exact match to original splines |
| Lubrication | Litol-24 or equivalent | Regular renewal of lubricant every 2 years |
| Resource | 50,000 - 80,000 km | Depends on road quality and driving style |
The lubrication of the spider plays an important role in its longevity. Many modern universal joints already have sealed bearings, but some models require periodic maintenance. If the design allows, you can fill the cavities of the cross with a special lubricant through a grease nipple, if provided.
It is also important to monitor the condition of the steering gear boots. If the boot is torn, dirt and moisture will get onto the splines and spider, which will accelerate their wear. Replacing the anthers should be done simultaneously with replacing the cardan shaft to ensure maximum protection of the mechanism.
Before starting work, be sure to photograph the position of the steering wheel and shaft to prevent misalignment during assembly and ensure correct steering geometry.
Frequently asked questions and errors when replacing
Often, beginners make mistakes associated with the wrong choice of tools or ignoring safety rules. For example, trying to unscrew rusted bolts without pre-treatment can lead to them breaking inside the hole. In such cases, the bolt will need to be drilled out, which makes repairs much more difficult.
Another common mistake is ignoring the need to check other steering components. If you had a knocking noise, it could be caused not only by the driveshaft, but also by the tie rod ends or rods. Therefore, after replacing the driveshaft, it is recommended to conduct a full diagnosis of the chassis.
It is also worth noting that on some models Nissan Almera Classic It may be necessary to adjust the wheel alignment after steering intervention. Although replacing the drive shaft itself does not change the alignment, any disassembly of the steering rack can lead to misalignment of the rods.
Is it necessary to do a wheel alignment after replacing the driveshaft?
In most cases, if you only changed the driveshaft and did not touch the steering rods, it is not necessary to do a wheel alignment. However, if you notice uneven tire wear or your car is pulling to one side, it is recommended that you visit an alignment shop for a check.
Is it possible to drive with a faulty steering cardan?
It is strictly not recommended to drive with a faulty cardan. Play in the steering system reduces the vehicle's handling and can lead to loss of control at high speeds or during an emergency maneuver. This is a direct threat to the safety of the driver and passengers.
How often should the steering joint be replaced?
The average service life of a part is about 50-80 thousand kilometers, but this greatly depends on operating conditions. On bad roads wear occurs faster. It is recommended to check the condition of the driveshaft at each scheduled maintenance.
What should I do if there is still a knocking noise after replacement?
If the knocking noise remains, perhaps the problem is not in the cardan, but in the steering rack, steering tips or silent blocks of the levers. Also check that the bolts are tightened correctly and that there is no play in the spline joint. Sometimes knocking noise can be transmitted through the steering column from other components.
