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.

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.

      Blue/grey smoke after idle

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.

      The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
