Oh Snap. Literally. Two Wheel Nuts Have Snapped.

Well... Shit. Just what I needed. Noticed a wierd noise coming from the rear left of my car as I was leaving work. The frequency of the noise is relative to how fast or slow the car is going, so I figure it's something to do with the wheel. When I get home I find this:

Missing nuts? What the hell? Upon closer inspection...

Two of the bolts have snapped clean off, leaving the thread down in the hub bit. I have no idea how this could have happened. It's got me absolutely buggered. I don't throw the car around very hard because I know my suspension, being still stock and 160,000km old isn't exactly A1 (which is why I'm saving for new suspension parts. I'm not exactly the most loaded guy out). Does anyone have any idea how something like this could happen? And more importantly, what I'm going to have to do to fix this? I'm assuming that I should keep the car off the road until this is sorted, because I don't exactly feel safe knowing my wheel nuts could seemingly just snap off for no apparent reason. What the hell should I do aside from obviously buy a new set of nuts (for the wheels :devil:)? I really didn't need another problem.

Poor wheel balance/alignment can cause it, but it has to be pretty bad. Otherwise spacers or someone using the wrong wheel nuts and threading the stud, and forcing the nut on/off can cause them to crack and after a while driving they will oh snap.

curious. i would recommend pressing the studs out, your wheels bearings will not thank you otherwise.

any sign of damage to the other wheel nuts? may be that last time you got new tyres some monkey with a rattle gun cross threaded them and then torqued them to within an inch of their life and cracked and just fell out, but it's still really strange.

i'm surprised that it made a noise though, wheels will hold on with only two nuts sometimes as it's the hub that takes the weight, the nuts just hold the wheel to it. noise usually means the wheel is loose.

as nik says poor fitting spacers will also kill them.

i'd check the other nuts out, seems almost as though someone is playing a nasty trick.

Hmm.. Ok, thanks for that guys. I guess my biggest concern is: can it actually be driven? I work in phillip but live in belco. If it can be driven I can probably get it looked at pretty much straight away and get what's needed since I work for a nissan dealership, I'm just scared as hell that the remaining wheel nuts could snap off too, seeing as it's happened twice.

I honestly don't think my wheel alignment is to blame, because it certainly wasn't/isn't that bad. I think there may be spacers on there, but I'm not 100% as I've never actually had any cause to take the wheels off myself. Guess what I'll be doing tommorow :laugh:

just taking a stab in the dark but do u have aftermarket wheels on ur car? If yes, check that the hub diameter of the wheel matches ur hub, it its bigger, then u need hub rings. Take it to a wheel shop n they should be able to tell u if u need them or not. If ur wheel hub diameter is bigger than ur hub, its actually putting stress on ur studs.

What n15m0 said is, I would be willing to bet, is the problem!

There seems to be many Skyline owners with non standard wheels running on the studs instead of the central hub rings.

It makes a lot of difference to the handling and safety of your car if ithe wheels are not a snug fit on the hubs.

CHECK your wheels now guys!

they have been over tightened at one point in there life, most probably from a rattle gun...

totally agree....over torqued in the past weakened them, maybe together with an incorrect size hub ring on aftermarket wheels.

Anway....assuming the nuts are still tight it will be safe to drive (carfeully) to a local tyre shop they can check out the other studs and replace those ones for you.

And when they are finished if you see them tighten them with a rattle gun ask what the wheel nuts were torque to....nissan says 110nm.

I have seen a whole wheel fall off a race car from overtightened wheel nuts....it made the car real hard to drive.

Had similar problem...

Can be caused by the wheel nuts comin loose..

Mine did that... had funny noise coming from front left wheel couldnt work it out. then noticed nuts were loose, touched one and it snapped..

just an idea.

I had a similar problem not long ago. Heard a weird noise from the rear end and pulled over to have a look, two nuts were missing, one stud was snapped and the other three nuts were loose. Seems weird this would happen to only one wheel when i tightened them all exactly the same way.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
