Broken wheel stud and lug nut.

molamann

I just got off the phone and parts dept. is telling me part #999h1-a7009 is supposed to the be wheel locks for my 370Z. However, a quick google search shows that the wheels locks are for 370Z Grand Touring/Track models and Frontier LE. So I told him to look up part #999W2-JT000 and #999W2-Z3409 which is supposedly the correct wheel locks for the 370Z and he told me that it is nonexistent in their bench stock.

So I'm kind of confused on what I'm supposed to do now since they already charged me $169 for wheel locks that they never installed in the first place. I asked him several times if he's 100% sure whether the wheel locks he told me are correct and he kept insisting that is the right part #. I highly doubt the dealership will refund me the money either so should I just wait a couple of months until the dealership gets a clue?

First of all, thanks everyone for keeping this thread alive. If it wasn't for this thread, I would probably never looked at this issue.

Part no. 999H1-A7009 is the wrong part for this car! That's what my dealer installed on my car. These lug nuts are so bad, it took 0 effort to take them off my car!!! They don't even thread all the way on the bolt.

I installed the new locking nuts and finally I could actually tighten them on the bolt.

If your dealer gave you a FREE set of locking nuts, please go outside and inspect them. I am including some pictures so that you can understand better.

Thanks everyone and I can finally drift sideways without worrying about my lugs exploding!

Thanks AK, those look much better! Essentially you've been driving around with only 4 nuts on each wheel all this time, kind of scary.

semtex

Well....where are the wheel locks? Do you have them separate somewhere? If not, I'd just drive back, get the sales manager and point at your wheels and ask him 'where the heck are my locks???'

Then he'll just be like, "we'll install em right away!"

With the wrong wheel locks of course(#999h1-a7009)


Also, I've checked everywhere for wheel locks in my car and they're nowhere to be seen.

ChrisSlicks

Just stay with what you have until they can get the correct ones. Whatever you do don't let them install the 350Z ones (#999h1-a7009), you will both regret it!

I'm still trying to come to grips with the nitrogen charge. Check out this link:

Thanks for the pics, AK, I too can now drive with peace of mind lol. This whole thing really had me confused, but I got the JT000s, which are meant for the G35, according to the included instructions.

Of course, I couldn't tell this until opening the package, and was basically SOL on returning it, so I decided to go ahead and compare it to the regular lug, and they looked identical in every measurement, so I concluded it had to be fine. After installing I saw this thread, and it had me second guessing the locks... especially when I rechecked the site I got them from and they listed the Z3409 part number.

Courtesy Nissan assured me, when I called them, that both part numbers exist, and are in fact the same. Evidently they label the same locks individually for each car model so people can be assured they got the right locks for their car. With that kind of policy, I find it ironic this whole mess has occurred on such a grand scale.

looks like its a perfect fit hopefully there wont be any problems

That McGard part shouldn't really be used as it doesn't have the washer nor a tapered end.

tru_Asiatik

it did come with washers same one semtex has on his pic
does it matter if the ends are tapered????

The taper helps to center the stud (not wheel). Probably not a huge deal when you have 4 other lugs already doing this, but it would have been better to get the ones from courtesy nissan.

semtex

I disagree. The taper makes zero contact with the wheel -- you can see this if you just take off one of your stock lugs and look closely at where the marks/scratches are. The taper is completely irrelevant. What centers the wheel is the hub, not the lug nuts. Hence the term 'hub-centric', as in hub-centric wheel spacers, for example. Think about it. Mount your wheel, but before putting any lug nuts on, if you move the wheel side to side, do the walls of the holes bang into the studs? No, they don't, because they're already centered.

I do agree that it's better to get the ones from Courtesy, now that they're finally available (I got my McGards before the 'real' ones were available). If you've already got the McGards, however, I see no reason to waste your money on ordering another set from Courtesy. I've had mine on for 4 months now without any problem whatsoever.

I ordered the McGard wheel locks because of this recommendation... They are incorrect, you should take them off your car, they are just as dangerous as the incorrect ones people got... They aren't correct because the width isn't wide enough, they are so narrow they actually BENT the washers

Just my 2 cents

cave vulture

Add me to the list of incorrect wheel locks. Dealer was totally oblivious to the situation.......
