Removing the steering wheel on a Nissan Terrano: step-by-step analysis with photos and advice from experts

Removing the steering wheel Nissan Terrano - a procedure that may be necessary when replacing an airbag, repairing a steering column, or installing a new steering wheel. Despite its apparent simplicity, the operation requires accuracy and knowledge of key nuances: from proper shutdown power supply before working with airbag squib. Mistakes here are fraught not only with damage to parts, but also with the risk of triggering pyrotechnic elements.

In this article we will analyze the process of removing the steering wheel on models Terrano R51 (2014–2020) and Terrano R20 (2005–2014), we will indicate the necessary tools and warn against common mistakes. We will pay special attention differences in the steering wheel mounting on versions with and without a multi-function steering wheel, as well as rules for handling contact groups. If you are planning to do this for the first time, read the instructions to the end before picking up the tools.

Preparation: Tools and Safety Precautions

Before starting work, make sure you have everything you need. To remove the steering wheel Nissan Terrano you will need:

• 🔧 Socket wrench or socket on 19 mm (for steering wheel nut)
• 🔧 Flat blade screwdriver (for airbag removal)
• 🔧 Plastic pullers or awl (for dismantling decorative panels)
• 🔋 Multimeter (to check if the airbag is powered off)
• 🧤 Dielectric gloves (static electricity protection)
• 📸 Phone or camera (to record the location of the wires)

Key point - system de-energization. Disconnect the negative terminal of the battery and wait at least 10–15 minutesso that the capacitors in the airbag circuit are discharged. On models with the system Nissan Intelligent Key additionally remove the key from the passenger compartment - otherwise the control unit may remain energized.

⚠️ Attention: If the indicator on the dashboard is on SRS/AIRBAG, it is strictly forbidden to remove the steering wheel until the problem is eliminated. This may cause the airbag to deploy uncontrollably.

Step 1: Removing the airbag

The airbag is attached to the steering wheel with four latches hidden under plastic plugs. On models Terrano R51 The plugs are located behind the steering wheel (interior side), on R20 - may be in front. Carefully pry them off with a flat-head screwdriver, starting from the bottom:

1. Insert a screwdriver into the groove of the plug and press upward.
2. Repeat for all four stubs (usually marked with arrows or a SRS).
3. Disconnect the airbag connector by pressing the latch (it may be orange).

After disconnecting the connector do not place the pillow on the floor or metal surfaces - Static electricity can damage the squib. Place it in a box or on a soft cloth, face up.

Step 2: Removing the decorative trim and accessing the steering wheel nut

Under the airbag there is a decorative trim that covers the steering wheel nut. On Terrano it consists of two parts:

• 🔄 Top overlay (with logo Nissan) - can be removed by pulling towards yourself.
• 🔄 Bottom overlay - attached to latches that need to be pressed out with a screwdriver.

After removing the covers you will see a nut on 19 mm and a contact group (if the steering wheel is equipped with control buttons). Do not try to unscrew the nut right away — first disconnect the connector of the contact group by pressing the latch. On some versions, the connector may be hidden under an additional plastic cover.

⚠️ Attention: If your model has heated steering wheel, before disconnecting the contact group, take a photograph of the location of the wires - they can easily be confused during reassembly.

Step 3: Unscrewing the steering wheel nut and removing the wheel

The steering wheel fastening nut is tightened with great force (tightening torque - 50–60 Nm). To unscrew it:

1. Install the socket wrench or socket onto the nut.
2. Pull the nut out of place with a quick movement (you may need a wrench extension).
3. Unscrew the nut completely, but do not remove it completely - it keeps the steering wheel from falling.

Now you need pull the steering wheel off the shaft. There is a nuance here: on Terrano The steering wheel fits on the splines with tension, so simply pulling it won’t work. Use a special puller or proceed as follows:

• 🔨 Gently tap with a hammer through the wooden spacer on the rim of the steering wheel on the driver's side.
• 🔄 Swing the steering wheel left and right, gradually pulling it off the shaft.
• 🚫 Do not hit the shaft or steering column switches - this may damage the steering column.

If the steering wheel does not budge, check that the nut is completely unscrewed. Sometimes it pushes against the washer, creating the illusion of a tight fit.

What to do if the steering wheel is stuck?

On some Terrano after 2018, the steering wheel may “stick” to the shaft due to corrosion. In this case:

1. Treat the joint with a penetrating lubricant (for example, Liqui Moly Rostloser).

2. Wait 30–60 minutes.

3. Use a three-jaw puller, evenly loading the steering wheel.

If this does not help, contact service: forced removal may damage the shaft splines.

Step 4: Disassembling the contact group (if equipped with a multi-steering wheel)

If your Terrano equipped with control buttons on the steering wheel (multi-steering wheel); after removing the wheel itself, you will need to dismantle the contact group. It is attached to the steering column with two Phillips screws:

1. Unscrew the screws and remove the plastic casing of the contact group.
2. Disconnect the connector by first pressing the latch (usually white or gray).
3. Carefully remove the contact group, do not pull the wires!

When reassembling, make sure that the contacts are not dirty or oxidized. To clean, use contact spray (For example, CRC Contact Cleaner). If the buttons on the steering wheel stop working after assembly, check the integrity of the spring contact inside the group.

Malfunction	Reason	Solution
The steering wheel cannot be removed despite the nut being unscrewed	Corrosion on shaft splines	Apply lubricant and use a puller
Lights up after assembly SRS on the panel	Incorrect airbag connection	Check the connector, reset the error using a scanner
Multifunction steering wheel buttons do not work	Contact oxidation or group damage	Clean the contacts, check the integrity of the wires
The steering wheel rotates with play after installation	Fastening nut is loose	Tighten the nut to torque 50–60 Nm

Step 5: Steering Wheel Installation and Reassembly

When installing the steering wheel, follow the reverse order, but keep in mind a few critical points:

• 🔧 Tighten the fastening nut to two stages: first by hand, then with a torque wrench with force 50 Nm.
• 🔌 Connect the airbag connector lastwhen the steering wheel is already secured.
• 📋 After assembly, check the operation of the airbag using a diagnostic scanner (for example, Launch X431).

Pay special attention to the centering of the steering wheel. On Terrano marks for correct installation are located on the shaft and steering column. If they are not combined, the steering wheel will be crooked, and when driving in a straight line, the wheel will have to be kept in the turn.

Common mistakes and how to avoid them

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

1. Ignoring waiting after battery disconnection. The capacitors in the airbag circuit do not discharge instantly. Minimum waiting time - 10 minutes.
2. Using excessive force when removing the steering wheel. Hitting the shaft or lever with a hammer can deform the steering column.
3. Mixing up the connectors of the contact group. On models with a heated steering wheel, the wires can be easily mixed up - always take a photo of the original position.
4. Incorrect nut tightening. Weak tightening leads to play, excessive tightening leads to damage to the column bearing.

If after assembly the indicator on the dashboard lights up SRS, don't panic. In most cases, the error can be reset using a diagnostic scanner. However, if the indicator continues to light, contact a service center to check the airbag circuit.

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

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

Yes, but it requires caution. Instead of a puller, use a wooden spacer and a hammer, tapping the steering wheel rim from different sides. The main thing is not to hit the shaft or apply excessive force, so as not to damage the splines.

What should I do if the steering column switches do not work after removing the steering wheel?

Most likely, the contact group was damaged during assembly or the connectors were mixed up. Check the integrity of the spring contact inside the group and the correct connection of the wires. On models with Nissan Connect The multimedia system may need to be restarted.

Do I need to remove the steering column to replace the steering wheel?

No, the steering column is removed only when it is repaired or replaced. To remove the steering wheel, just unscrew one nut and disconnect the connectors. The exception is models with electric power steeringwhere additional sensor disconnection may be required.

How to check that the airbag is disabled?

After disconnecting the airbag connector, check the resistance between the contacts with a multimeter. It should tend to infinity (chain break). If the device shows resistance, the circuit is not broken and the cushion remains energized.

Is it possible to drive without an airbag if it is removed?

Technically it is possible, but it is extremely unsafe. System SRS will generate an error, and in the event of an accident you will be left without protection. If the airbag is removed temporarily (for example, to paint the steering wheel), drive only to the nearest service center.
