Steering is a critical component of any car, the health of which directly affects the safety of the driver and passengers. On models Nissan Almera of new and previous generations, especially with a mileage of more than 100,000 km, owners often encounter a characteristic knocking sound in the steering wheel when driving over bumps. This sound indicates wear or looseness of the fastener. steering rack, which requires immediate intervention.
Many car owners mistakenly believe that the appearance of a knock means the need to completely replace the unit, which entails serious financial costs. In fact, in many cases the problem can be solved by simply gap adjustment in the mechanism. The tightening procedure allows you to eliminate play, restore clarity of control and delay expensive repairs or replacement of the unit for several years.
Symptoms of malfunction and diagnostics of backlash
The first and most obvious sign that the steering rack is on your Nissan Almera requires attention, there is a knock that is felt through the steering wheel. It usually appears when driving on uneven roads, when the wheels pass through asphalt joints or small holes. The sound is often described as a "knock-knock" or metallic grinding sound coming from the front of the cabin or under the hood.
In addition to acoustic signals, the driver may notice the appearance of free play in the steering wheel. If you turn the steering wheel a small number of degrees and the car's wheels do not respond immediately, this indicates significant wear on the gear pair or a loose adjustment screw. It is also worth paying attention to the condition of the anthers: if they are torn, moisture and dirt have gotten inside the mechanism, which accelerates the destruction process.
It is important to understand the difference between a knock in the rack itself and a knock in the tie rods or ends. Diagnostics must be carried out comprehensively so as not to tighten the rack if the problem lies in the ball joints. To accurately determine the source of the noise, you need to raise the car on a lift and ask an assistant to shake the steering wheel while the technician inspects the suspension.
- 🚗 The appearance of a knock when passing speed bumps.
- 🔧 Increased free play of the steering wheel by more than 10-15 degrees.
- 💧 Presence of traces of power steering fluid leakage or ruptures of rubber boots.
⚠️ Attention: If the knock is accompanied by vibration of the steering wheel at high speeds, this may indicate not only a problem with the rack, but also a violation of the wheel alignment or deformation of the suspension arms.
Sometimes the problem is disguised as other problems. For example, the knocking noise may come from the steering column universal joint shaft, which connects the steering wheel to the rack. In such cases, tightening the rack itself will not give the desired result, and the driver will be left disappointed. That's why diagnostics must be thorough.

Tools and preparation for work
Before you start making adjustments, you need to prepare all the necessary tools. The work is carried out under the car, so the presence of a reliable lift or inspection hole is a prerequisite. The use of jacks and sawhorses is acceptable, but requires increased caution due to the risk of the vehicle moving.
The most important tool for this procedure is special key to adjust the steering rack. By car Nissan Almera (G11, N16, N17) a hex key or a special head is used, the size of which depends on the year of manufacture and modification. This is usually a 10mm, 12mm or 14mm hex, but it is best to check the technical documentation for information before purchasing.
You will also need a standard set of wrenches and sockets, a tie rod end remover (if you need to remove them for access), and WD-40 or a similar penetrating lubricant. The adjusting screw often sticks to the body due to corrosion, so pre-treatment is required. Don't forget to prepare a rag to clean the work area from dirt.
- 🛠️ Special key for tightening the rack (hexagon or socket).
- 🔦 A powerful flashlight for inspecting hard-to-reach places under the hood and underbody.
- ⚙️ Set of sockets and extensions for removing engine protection.
☑️ Preparation of the workplace
It is equally important to ensure proper lighting of the work area. The steering rack is located in a tight space between the subframe and the engine, and poor visibility can lead to the edge of the key breaking off or damaging adjacent components. Make sure you have access to the adjustment bolt, which is often hidden under a protective cover or steering shaft boot.
⚠️ Attention: Before starting work, be sure to disconnect the negative terminal of the battery to prevent accidental switching on of the power supply or deployment of the airbags when dismantling the elements.
Step-by-step instructions for adjusting the gap
The tightening process begins with the dismantling of elements that prevent access to the adjusting screw. Typically this is the lower part of the steering shaft that goes through the engine shield, and the protective covers under the hood. Carefully unscrew the mounting bolts, being careful not to damage the rubber seals. If the adjustment screw is at the bottom, you may need to remove the crankcase guard.
Once access is open, apply penetrating lubricant to the threads of the adjusting screw and allow it to soak in for a while. Then, using a special wrench, begin to carefully rotate the screw clockwise. It is important to do this in small portions, 15-30 degrees at a time, and constantly check the result by touch or with the help of an assistant who will turn the steering wheel in place.
The main task is to eliminate the backlash without over-tightening the mechanism. Excessive tightening will cause the steering wheel to become “heavy” and the wear of the gear pair will accelerate significantly. The ideal result is the absence of knocking while maintaining light and smooth steering. If you feel resistance when turning the steering wheel, then you have gone too far and need to loosen it a little.
After achieving the desired result, you need to fix the position of the screw. A locknut or a special thread locker is often used for this. Make sure that the screw does not turn when the vehicle is moving. If the design includes a locking bolt, it must also be tightened securely.
What to do if the screw does not turn?
If the adjusting screw is stuck, do not try to apply excessive force, as this may strip the threads. Use more penetrating lubricant, heat the area with a heat gun, or gently tap the screw head through the spacer to break up the corrosion layer.
Typical mistakes and nuances of the Almera model
Owners Nissan Almera They often make the same mistake: they try to tighten the rack without checking the condition of the universal joint shaft. On these models, the shaft often has its own play, which simulates a rack malfunction. If you tighten the rack and the knocking noise remains, you will have wasted your time and effort. Always check the steering shaft driveshaft separately.
Another common problem is using the wrong tool. Conventional hexagons from a cheap set often have imperfect geometry, which leads to the edges breaking off on the soft metal of the adjusting screw. If you break an edge, adjustment will become impossible and you will have to replace the entire assembly or look for complex restoration methods. Use only quality tools.
It is also worth considering that on some modifications Nissan Almera (especially with electric power steering) the design may differ from the classic hydraulic rack. In such cases, the adjustment mechanism may be missing or inaccessible without complete disassembly of the assembly. On models with electric power steering, tightening is often impossible, and replacement of worn bushings or the entire mechanism is required.
Before you start turning the screw, take a photo of its current position. This will help you understand how far you have cranked it if you have to unscrew everything back because of the constriction.
Comparison of self-repair and service calls
The decision whether to do the tightening yourself or contact a car service depends on your skills and the availability of tools. Doing it yourself can save you a significant amount of money, but it requires time and care. The service will offer you a guarantee for the work, but the cost can be several times higher than the price of the tool itself.
The table below compares the key features of both options to help you make an informed decision.
| Parameter | Independent work | Car service |
|---|---|---|
| Cost | Only the price of the tool (500-2000 rubles) | Work + tools (2000-5000 rubles) |
| Time | 1-2 hours if you have experience | 30-60 minutes (queue + work) |
| Risks | High with no skills | Minimum (guarantee) |
| Diagnostics | Difficulty pinpointing the source of the knocking noise | Professional lift inspection |
If you are not confident in your abilities or do not have access to a lift, it is better to entrust the work to professionals. An adjustment error can lead to loss of control in an emergency, which is much more expensive than the cost of a service visit. However, if you have experience in car repair and the necessary tools, doing the lift yourself is a completely doable task.
The main purpose of the tightening is to eliminate play without losing the ease of rotation of the steering wheel, otherwise the wear of the mechanism will accelerate significantly.
Owner Frequently Asked Questions (FAQ)
How long does the rack tightening procedure take?
If you have a lift and a special key, the process takes from 30 minutes to 1 hour. If it is necessary to remove the engine protection and look for access to the propeller, the time may increase to 1.5-2 hours.
Is it possible to tighten the rack if it is leaking?
No, tightening if there is a leak is ineffective. Leakage of power steering fluid leads to a decrease in pressure and wear of seals. First you need to replace the seals or repair kit, and only then adjust the gap.
Is it necessary to do a wheel alignment after a facelift?
If you did not remove the tie rods and ends, the wheel alignment will not be affected. However, if you changed the position of the steering wheel or removed suspension elements, checking the geometry is required.
How often should the steering rack be tightened?
The adjustment is not a planned procedure. It is performed only when knocking or play occurs. Frequent tightening can lead to rapid wear of the gear pair due to excessive compression.
What to do if after tightening the steering wheel becomes heavy?
This is a sign of constriction. You must immediately loosen the adjusting screw by 15-30 degrees until the steering wheel turns easily. A heavy steering wheel puts stress on the power steering pump and can lead to its failure.
