Removing the steering wheel Nissan Almera Classic (including modifications B10 And N16) is a task that owners face when replacing an airbag, repairing a contact group or tuning the interior. Despite its apparent simplicity, the procedure requires caution: errors during dismantling can lead to activation of the squib airbags or damage to the steering column. In this article we will analyze the process step by step, indicate unique nuances for Almera Classic (for example, features of fastening the steering wheel on models with power steering) and warn against common mistakes.

Important: if you plan to work with electrical part (for example, replacing the slip ring), be sure to disconnect the battery before 10–15 minutes before work starts. This is necessary to discharge the capacitors in the airbag system. On models Almera Classic with SRS (Supplement Restraint System) ignoring this rule may lead to uncontrolled activation of the squib even with the terminal disconnected.

Preparation: Tools and Safety Precautions

Before you begin removing the steering wheel, prepare your work area and tools. For Nissan Almera Classic you will need:

  • 🔧 Socket wrench or socket on 19 mm (for the steering wheel nut).
  • 🔧 Screwdriver with a flat blade (for removing the airbag).
  • 🔧 Plastic pullers or wide screwdriver (for dismantling decorative panels).
  • 🔋 Multimeter (to check the airbag circuit after disconnection).
  • 📸 Smartphone (to photograph the location of wires and marks).

Pay special attention steering wheel fixation before removal. On Almera Classic with hydraulic booster (HPS) the steering wheel may turn after unscrewing the nut, which will complicate reassembly. To avoid this, use retaining strap or lock the wheels in a straight position using the hand brake.

⚠️ Attention: Do not use an impact tool (for example, an air impact wrench) to unscrew the steering wheel nut! Sharp impacts can damage worm gear steering column, which will lead to play or uneven rotation of the steering wheel after assembly.

Step 1: Removing the airbag

Airbag (SRS Airbag) is the most critical element when removing the steering wheel. On Nissan Almera Classic it is attached to the steering wheel with two plastic latches, which are located on the reverse side. To remove the pillow:

  1. Disable negative battery terminal and wait 10–15 minutes.
  2. Insert a flat-head screwdriver into the technological holes on the back of the steering wheel (they are located symmetrically, at an angle of ~45°).
  3. Gently press the latches while pulling the pillow towards you.
  4. Disconnect the airbag power connector (it has yellow color and retainer).

On models Almera Classic with leather steering wheel The pillow may fit tighter due to the adhesive layer. In this case use plastic pullerso as not to damage the casing. After dismantling, put the pillow face up on a soft surface - this will prevent accidental activation of the squib.

What to do if the latches are broken?

If the plastic airbag latches are cracked, do not try to glue them together! Replace the mount with a new one (article number for Almera Classic: 40501-4M000). The use of damaged latches may lead to spontaneous detachment of the airbag during movement.

Step 2: Unscrewing the steering wheel nut and removing the wheel

After dismantling the airbag, we proceed to unscrewing the central nut. On Nissan Almera Classic she has left-hand thread (unscrews clockwise!), which often causes errors. Use the head on 19 mm with an extension, since access to the nut is limited.

Important details:

  • 🔧 If the nut does not budge, apply a penetrating lubricant (for example, WD-40) and wait 5–10 minutes.
  • 🔧 Do not use excessive force - on models with EPS (electric power steering), the steering angle sensor can be damaged.
  • 📸 Before removing the steering wheel, take a photo of its position relative to the shaft. On Almera Classic The mark on the steering wheel must match the mark on the column (usually a mark on the plastic casing).

After unscrewing the nut, the steering wheel can sit tightly on the splines. To remove it, use steering wheel puller or gently tap the steering wheel rim from the back through the wooden spacer. Never hit directly with a metal hammer - this will deform the splines.

Step 3: Features for Hydraulic Power Steering (HPS) Models

On Nissan Almera Classic with power steering (HPS) the removal process has additional nuances:

  1. System pressure: Before starting work, make sure that the engine is turned off for at least 30 minutes - this will relieve pressure in the hydraulic system.
  2. Steering wheel position: The wheels must be set strictly straight. If the steering wheel was turned while the nut was unscrewed, during assembly a label mismatch, which will lead to incorrect operation GWS (rotation angle sensor).
  3. Hoses and pipes: On models with HPS Hydraulic lines run under the steering wheel. Do not pull the steering wheel too hard as this may damage the rubber seals.

If after assembly you notice tight steering wheel rotation or extraneous sounds (e.g. creaking), check:

  • 🔧 Correct installation of the steering wheel according to the marks.
  • 🔧 Integrity of the steering column boot (on Almera Classic it often breaks when removed carelessly).
  • 🔧 The fluid level in the power steering reservoir (should be between the marks MIN And MAX).
💡

If after assembly the steering wheel rotates with force, try “bleeding” the power steering: with the engine off, turn the steering wheel from lock to lock 5–6 times, then start the engine and repeat the procedure.

Step 4: Checking the contact group and sensors

After removing the steering wheel, inspect contact group (it is located under the steering wheel, on the column shaft). On Nissan Almera Classic common problems:

  • 🔌 Oxidation of contacts (leads to flickering dashboard lights).
  • 🔌 Wear of conductive tracks (causes steering wheel buttons failure).
  • 🔌 Damage to the spring mechanism (the steering wheel may rotate independently when driving over uneven surfaces).

To check a contact group:

  1. Disconnect the connector and inspect the contacts for oxides.
  2. Test the circuits with a multimeter in 200 Ω (resistance between contacts should be no more 0.5 ohm).
  3. Check the smooth rotation of the slip ring - it should rotate without jamming.

If the contact group is damaged, replace it with a new one (original part number for Almera Classic: 25540-4M000). When installing a new part, apply to the contacts conductive lubricant (For example, Kontakt 60).

Symptom Probable Cause Solution
Steering wheel buttons don't work Worn contact group or broken wire Replacing the group or soldering the wire
Instrument lights flash when you turn the steering wheel Oxidation of contacts or damage to tracks Clearing contacts or replacing a group
The steering wheel rotates spontaneously Breakage of the spring mechanism in the contact group Replacing the group assembly
Creaking noise when turning the steering wheel Wear of plastic steering column bushings Lubrication or replacement of bushings

Step 5: Steering Wheel Installation and Reassembly

When installing the steering wheel Nissan Almera Classic follow the reverse order, but keep the key points in mind:

  1. Tags: Align the mark on the steering wheel with the mark on the column shaft. On models with EPS mismatch of labels will lead to rotation angle sensor error (code C1130).
  2. Tightening torque: Tighten the steering wheel nut firmly 35–45 Nm. Over-tightening can deform the splines, and insufficient tightening can cause play.
  3. Airbag: When connecting the connector SRS make sure that the latch snaps into place (a characteristic click should be heard).

After assembly:

  • 🔋 Connect the battery and check the operation of the airbag (the light comes on and goes off SRS on the dashboard).
  • 🔄 Scroll the steering wheel from lock to lock to make sure there are no jams.
  • 🔊 Check the operation of the buttons on the steering wheel and the sound signal.
⚠️ Attention: If after assembly there is a light on the dashboard SRS error (code B1018 or B1019), this means there is a problem with the airbag circuit. Do not ignore it - contact a diagnostician to reset the error using Consult III or similar scanner.
💡

On Almera Classic models with electric power steering (EPS), the steering angle sensor must be calibrated after removing the steering wheel. To do this, turn on the ignition, turn the steering wheel all the way to the left, then to the right and return to the center position. The EPS light should go out.

Common mistakes and how to avoid them

Even experienced craftsmen make mistakes when removing the steering wheel. Nissan Almera Classic. Here are the most common:

  • 🔧 Ignore tags: Mismatch of marks on the steering wheel and shaft leads to Incorrect operation of the rotation angle sensor (especially critical for models with ESP).
  • 🔌 Damage to airbag wires: Sudden jerking of the connector SRS may break the wires. Always release it by pressing the release lever.
  • 🛠️ Using unsuitable tools: Key on 21 mm instead of 19 mm will tear off the edges of the nut, which will complicate further repairs.
  • 🔋 Failure to comply with the waiting time after disconnecting the battery: Capacitors in the block SRS do not discharge instantly - minimum waiting time: 10 minutes.

If you've made one of these mistakes, don't panic. For example, a broken nut can be drilled out, and torn pillow wires can be soldered (but only using special solder for automotive wiring). However, if the squib fires or the steering angle sensor is damaged, professional diagnostics will be required.

FAQ: Frequently asked questions about removing the steering wheel on a Nissan Almera Classic

Is it possible to remove the steering wheel without a puller?
