Skyline R34 Remove & Replace Steering Wheel & Airbag & Resetting Airbag Alarm


Recommended Posts

The wheel has splines. The shaft has splines. If you turn the wheel, the shaft turns the same number of degrees. If you take the wheel off and then rotate the shaft, then so long as you rotate the wheel to the same angle before you put it back on, then there is no change in the relationship between the wheel and the shaft, so nothing changes.

The easiest way to do this is with a little alignment mark on the end of the shaft running onto the wheel hub.

The only "release" described in the method is:

  1. Unlock the steering height angle adjuster, if needed, to allow the column shroud to be removed (again, if needed),
  2. Unlock the ignition barrel lock so the wheel can rotate. This is probably to prevent accidentally breaking the lock when you're beating the shit out of the wheel trying to get it to come off the spline.

Neither of those things will allow some sort of random repositioning of all the components in the steering column so that you now suddenly have your wheels facing off to a random side or pointing in different directions. The steering column is still rigidly connected to the rack. Put a pair of vice grips on the splines and you'll be able to steer the car (and get a massive defect and possibly die when you impale yourself on the shaft in the inevitable crash).

Ah ok, i think i get what you mean. thanks

Correct me if I'm wrong but one thing you didn't take into account was the clockspring as it's not meant to be turned. Or is the idea if the wheel is already turned, we just put the nut back on, and then straighten out the wheel to feed the clockspring wires through? If that's the case, I'm not sure if the clockspring spins as you turn the wheel. I imagine not otherwise all the copper wires would have ripped off the first time the very first time the wheel is turned, but at the same time I don't see it moving because the connectors stay in one place.

I'm probably overthinking.

The front of the clockspring turns with the steering wheel - or more to the point, with the splined shaft. The rear of the clockspring stays mounted to the column (not the shaft, the fixed part of the column).

Ah right, cheers.

Just keep in mind if you have a R34 Series 2, the airbag reset procedure is actually that of the V35, not the R34 as described in the R34 Workshop manual.

Just cause Nissan things.

Ah interesting, good to know. Is series 2 the 1999 model and onwards not 1998?

Do you know if I have my steering wheel disconnected or a week (airbag light will show if I put ignition on) or so if the airbag reset procedure will be harder to do? I did a search on the forum, and seems to be the case. At least with mine since I have an immobiliser I noticed the other day if I put the key on the on position in a short amount of time the alarm chirp, which also might cause me issues.

Lastly, will the airbag light show if I connect the battery terminal with the steering wheel disconnected but don't turn on the ignition? Obviously I won't see it if the ignition is off but my question is when I go to put the steering wheel back on if the light will show because I've had my battery connected.

Series 2 is Aug 2000 onwards. You'd know if you have one, cause a lot of stupid shit is mysteriously different (like the airbag reset procedure!)

Having it off for longer wont matter. Lets be real; if the car has been driving around with the airbag light 'on' that circuit is already broken and the airbag is already 'off'.

The procedure will work if you have all the parts and wires lined up right. Sadly I've removed and replaced and swapped a clock spring a couple times now. Once it's all apart it's quite noticeable how simple it is to put together/take apart.

Ah right, thanks for that. What about the above, whether the airbag light will likely show after i put the steering wheel on, if the airbag has previously been is disconnected and the battery is connected but the ignition is off? I guess an easier way to frame the question is, if I do the whole procedure with my battery connected but the ignition off the whole time whether it should show the airabag light?

I don't know. I don't think anyone would know. I would however expect that if you remove the clock spring or unplug the airbag at any time, for any reason, you would need to reset the light upon plugging it all back in again.

Ah ok, no worries. I'll take the risk and hopefully if I need to reset it that it's not a pain in the ass.

Am I reading this correctly? It's showing the steering wheel nut is only 39nm, which seems quite low. i thought it would be tighter. The sump plug max torque is 39nm which isn't tight.image.thumb.png.2d59de05cf9f5bfbc37719fa3b1a8811.png

Drag it back off and put it back straight. It'll only take you 2 minutes and the risk of a broken nose.

The problem is that, it's slightly off, the center pin doesn't line up with the spline. This is how it looks now. I can technically make it perfectly center, but the guide pins on the steering wheel and the clockspring it self won't sit in and be flush.

 

I attached the guide pins on the clockspring for reference.

From memory the wheel doesn't sit on the clockspring directly, so you can just remove the wheel, turn it however many angles it's off then put it on the spline again. I know this as I too have put it on one spline out before and gone "Ah everything works, the wheel is just not straight now"

Ah do you mean the 3 notches on the steering wheel and the clockspring don't need to line up? If that's the case, somehow I just got a weird scenario where i didn't align it and the steering wheel sits flush whereas before I had to have it aligned. My steering wheel is still crooked but just in the other direction. I already had a wheel alignment but I wonder if it's so off because the spline should be in the center if I'm not mistaken.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
