The process of removing a steering wheel from a car Nissan Almera Classic often raises questions among novice car owners. Many are afraid of damaging expensive airbag or break the plastic clips, which become brittle over time. In fact, if you follow the sequence of actions and understand the device steering column, the work will take no more than fifteen minutes.
Removing the steering wheel may be necessary to install an alarm system, replace airbags or carrying out work on the ignition switch. In some cases, this is necessary to repair the steering wheel itself, if additional control buttons are built into it. The main rule is that work with the electrical system should begin only after complete battery insulation.
Preparing the workplace and tools
Before you begin disassembly, you need to prepare a tool kit. You don't need complicated special tools, but having screwdrivers and sockets of different sizes is a must. Pay special attention to the quality of the tools so as not to tear off the edges of the bolts, which can be tightened with great force.
First, make sure the car is on a level surface and parking brake securely fixed. The wheels must be aligned strictly straight so that the steering shaft is not under load when turning. This will simplify the process of unscrewing the central bolt.
- 🛠️ 10 mm spanner or socket for battery terminals
- 🔧 Screwdrivers with Phillips and flat blades (it is better to use plastic blades)
- 🔨 Hammer with a rubber tip for knocking out the bushing
- 🔑 16-18 mm socket for central steering wheel mounting
It is important to clear the space around the steering column of unnecessary objects. Inside Nissan Almera Classic There are a lot of plastic panels that can be easily scratched with a metal tool. Place a soft cloth or cardboard on the dashboard.
Disabling the electrical system and removing the pillow
The first and most critical step is to de-energize the system. If you forget to remove the terminal, the impact sensor will be activated and the airbag may deploy in your hands, causing serious injury and interior damage. The process of removing the terminal requires care so as not to short the contacts to the housing.
Open the hood and find the battery. Using a 10mm wrench, loosen the nut on the negative terminal and remove it completely from the terminal. After this, it is recommended to wait about 10-15 minutes. During this time, the capacitors in the airbag control unit will be discharged, and the risk of accidental deployment will be reduced to zero.
⚠️ Attention: Never connect or disconnect the battery while the ignition is on! This may cause an error in the control unit SRS Airbag, which will then have to be reset through the diagnostic scanner.
Now you can proceed to removing the airbag. On Nissan Almera Classic it is attached to the back of the steering wheel through special holes. Insert a flat-head screwdriver into the access hole and gently press out the cushion retainer. Do this on both sides so that the mechanism releases evenly.
- 🚫 Do not pull the pillow sharply, the fixing latches are very fragile
- ⚡ Immediately disconnect the yellow connector with wires from the pillow
- 📦 Place the pillow face up on a soft surface
After removing the cushion, you will see the horn contacts and electrical connectors. They must be carefully disconnected by pressing the latches. If the wires are too tight, do not pull them, but slightly loosen the wire harness clamps.
Removing the central nut and clamps
After dismantling the cushion, access to the central nut, which secures the steering wheel to the shaft, opens. Does it have a left-hand thread? No, on most versions Nissan Almera Classic standard thread, right. However, when unscrewing, you always need to apply significant force, since the nut is tightened with a large torque.
Use a 16 or 18 mm socket (depending on the year of manufacture and modification) and a long crank for the lever. If the nut does not budge, you can use a penetrating spray WD-40, but only after making sure that it does not get on the plastic elements. You cannot jerk the knob sharply - you can break the splines.
The most important point is to remember the position of the steering wheel relative to the shaft. There is a shaft keyway, which should coincide with the groove on the steering wheel. If you remove the steering wheel and forget how it was positioned, it may not sit straight during reassembly, which will disrupt the steering geometry.
⚠️ Attention: Do not unscrew the central nut all the way! Leave it for a couple of turns so that when removing the steering wheel it does not fall sharply onto the chest or dashboard.
After the nut is unscrewed, you can proceed to removing the steering wheel itself. It sits on the shaft very tightly, often without cotter pins, only due to the cone and tightening of the nut. Simply pulling it with your hands is often not enough, especially if the car has traveled many kilometers.
Removing the steering wheel from the shaft
To remove the steering wheel from the shaft, it is best to use a special puller. If you don’t have such a tool in your arsenal, you can use the “bait” method. Screw the central nut back 2-3 turns so that it protrudes 5-10 mm above the shaft.
Next, you need to gently tap with a hammer on the end of the steering column or on the back of the steering wheel (not on the spokes!). The blows should be sharp and strong, but controlled. The vibration will help move the steering wheel out of its seat. As you tap, the steering wheel will begin to move and you can remove it by hand.
- 🔨 Hit strictly in the center of the shaft, avoiding hitting the electronics
- 🔄 Periodically check if the steering wheel has bitten the nut
- 🧼 Clean the shaft splines from rust and dirt before installing a new steering wheel
It is important to understand that removing the steering wheel is an operation that requires physical strength and patience. If you are using a puller, tighten the screw smoothly. A sudden movement can damage the threads on the puller screw or damage the shaft itself.

Checking the condition of components
After the steering wheel is removed, you have an excellent opportunity to inspect the condition of the steering components. Please note the condition universal joint, which connects the steering column to the mechanism. On Nissan Almera Classic it often suffers from corrosion and backlash.
Inspect the steering shaft fork for cracks and deformations. If the splines show severe wear or traces of corrosion, they must be cleaned and lubricated with lithium grease. Ignoring this step may result in the steering wheel being difficult to remove next time.
Also check the integrity of the wiring harness going to the airbag and horn. The insulation often frays at bending points. If you see damage, the wires need to be replaced or properly insulated.
Steering wheel installation and final assembly
Installing the steering wheel is the reverse process of dismantling, but with important nuances. First, align the splines on the shaft and the steering wheel. Make sure the steering wheel is level with the steering rack. If the wheels were set straight, then the steering wheel should be horizontal.
Tighten the center nut as tight as possible. The tightening torque should be within 40-50 Nm. If you don't have a torque wrench, tighten it all the way, but not too much, so as not to strip the threads. The nut should fit tightly and not turn.
☑️ Check before installing the pillow
Connect the electrical connectors to the airbag and horn. Make sure the contacts snap fully into place and are not loose. Only after this can you carefully insert the cushion into the seat on the steering wheel.
⚠️ Attention: Before attaching the battery terminal, make sure that the steering wheel is level and does not block access to the pedals or gear shift lever!
Install the negative terminal on the battery and tighten it. Now you need to check the operation of the system. Turn on the ignition and look at the dashboard. The airbag light should come on for 3-5 seconds and go out. If it is constantly on or blinking, there is a connection error somewhere.
Common mistakes when removing the steering wheel
Many car owners make common mistakes that lead to additional costs. The most common mistake is trying to remove the steering wheel without disconnecting the battery. This is not only dangerous, but can also lead to a short circuit and failure of the SRS control unit.
Another common problem is using the wrong tool to remove the nut. If you use a wrench or wrench that is too small, you can easily tear off the edges. As a result, you will have to drill out the nut, which will significantly complicate the work.
It is also worth noting installation errors. If the steering wheel is not leveled before tightening the nut, the steering wheel will remain crooked even when the vehicle is moving straight. This not only spoils the appearance, but also creates discomfort when driving.
| element | Tool | Tightening torque (Nm) | Note |
|---|---|---|---|
| Steering wheel center nut | Head 16-18 mm | 40-50 | Pull away from you when unscrewing |
| Battery terminal | 10 mm wrench | 4-6 | Remove the first minus |
| Pillow fastening | Flat head screwdriver | No | Snap fasteners |
| Pillow connectors | Manual | No | A click is heard when locking |
| Wiring harness | Plastic clamps | No | Don't overtighten |
In conclusion, it is worth noting that removing the steering wheel Nissan Almera Classic - this is a completely feasible task for any car enthusiast with a minimum set of tools and knowledge. The main thing is to take your time, follow safety precautions and carefully monitor the condition of all components.
