Hey Guys,

I'm hoping someone here can help me,

Last night whilst driving home, i had a blow out :), alas i pulled over, jacked the side up and found that the wheels on the car have a lock nut, to which the previous owner did not give me on sale what i wanna know is, can i take it to a tire shop and show all the paperwork to state i own the car etc to get these locknuts taken off and replaced?

i ended up havin to drive on a flat :), even that tire inflate foam stuff didn't work.

Any help greatly appreciated.

not really. There are many different brands of lock nuts. In each brand, there are probably 500 combinations.

On the locknut key, there is usually a number, and you have to know which company it is too. You can't just go to the shop, because a) they won't know what key it is and b)they won't know who makes it.

i'm sure they'd do it if they could.

Your best bet would have to be to try and contact the previous owner. If not, the only way to remove it, would be the good old mechanical way? Hit it hard with a hammer to loosen it, then try to drill the lock nut off, or drill a hole in the back of the stud and use an extractor?

tough situation. Sorry I couldn't offer what you wanted to hear

Note to self - i've had a half worn lock nut tool. I'm gonna try and buy a new key, or change the locknuts before they get stuck.

Cheers

have a look everywhere througout the car, ie. in the boot around spare wheel, in map pockets, glove box, centre console. pockets behind seats etc. if you havent owned the car for long, the locknut key might still be there hidden away somewhere.

vicegrips sometimes work to remove locknuts, but if the bolt holes on the wheels are sunken in, then there that probably wont work. Or maybe you can make a mould of the locknut key with something? i dunno, get some clay or some shit - worth a try

If you still can't get it, you'll probably have to drill out the stud, but studs are pretty easy to replace

I had this problem on a friends car but we eventually found the locknut key. First thing we did after that was remove the locknuts for good!

I had the same problem(except for the blow out)

Just foun different sized sockets that were close to the size, went to Cash Converters and bought some around that size for 50c each then bashed em on the lock nut.

(bought 2nd hand ones cause they were gunna get ruined anyway)

Was hard work but had to be done, and did finally get there in the end

same problem...i had a blow out not very long ago..and that was my worst fear as i bought the car and had no idea where the lock nut key were as the previous owner now overseas...i tried all autoshops that sells them.

pretty much make a mould of it...and then take it with you and compare if the ones they have down the shop would fit...i hadn't had luck though.. got home and check all the compartments that maybe it was just hidden somewhere...and i found it in the glove box.. DOH...i should have looked first..LOL.

Anyways...a friend of mine had the same thing..he took it down to machine shop and had them taken off..pretty much what they did was stick a metal to the nuts and weld them.. i must say he done a pretty good job...and he made it look easy.

hope that helps.

any decent tyre placeshould be able to remove the nut without the tool it came with. just call them up and say "i have a nock nut on my wheel but ive lost the fitting to remove it, can you remove it at the workshop"

i can pretty much guarantee you they didnt use my fitting and managed to take my wheels off change the rubber and put it back on within about 4 minutes.

get a nice strong socket a lil larger than the nut, then get a nice tough hammer.

and put the the socket over it and start smashing it on!!

hopefully the socket is stronger than the nut though

then it will just wedge into shape and use the wrench to twist!!

kapish??

Im with silver gts-t.That is exactly what i had to do to mine to get the lock nuts off after i lost it.Look everywhere for the lock nut key.

1st i found a nut that would go over it neatly then one just down from it's size that wouldnt go on,1-2mm undersize,maybee 1mm under cant remember

Then went to hardware house looked in their $1 socket boxes found the size i wanted and got 4 of them i rooted 1 and then i used 1 for the rest of the 3 nuts,lucky i guess.

just bash them on using somthing to space the nut and the hammer.I used another socket in between,so as to not damage the rim.

Another way is to pack the socket with bits of steel ie.pop rivet shafts/offcuts.To further wedge and give more grip on the lock nut.

I know for a fact that there are tools as stated above that are a 1 size fits all socket head and they are packed with 100 or so more rivet style shafts but are actually made for this sort of thing.

Does your lock nut have ridged bumps on it or is it flat on the outside?

I am in the same situation at the moment. Went to get some new tyres today but couldnt find the fkn key. Was not happy. I bought the tyres but did not get them fitted. Spent about 15mins looking thru the car in the shop - still didnt find it. very p!ssed off, looked like a tool. Also got done 105 in a 80 zone ($250 4 points) on the way home. Havin a top weekend !!!!

Will try and find the combination for the key - I think remember the guy at the tyre shop recording the combination of the lock nut about 18months ago when I bought it. Might give them a call on monday morning....

I dont like the idea of smashing a normal socket bit over all 4 of my rims and buying a new set of lock nuts....

ok.... i know i am retarded... :rofl: but whats this lock nut key thing ??

and wheres about does it go ? i had a look on my tyres... cant see key hole type objects... alltho the thing in the middle of the rims on my car is missing.. its like a round thing right in the middle..

perhaps it looks that thing up ??

You might not have lock nuts on your wheels?

One of these 'special' bolts goes onto each wheel (replacing a normal nut) and the socket bit is the 'key'. Capiche?

thanks for that.. yeeah i've got those on my wheels... only problem is.. the wheels i got for my car arent standard (there for a gtr or something?) and the thing you use to unscrew em doesnt fit (there was one in the boot)... evan one of those that looks like a cross (has a differant type of bolt remover thing on each side.. forget what its called :thumbsup: ) i need one thats like EXTRA thin.. theres like 2mm between the nut and the rim

Sounds like you need a 19mm spark plug socket. If you are still confused just go to your local tyre shop, they will help you. If you live in the western suburbs i could give you some assistance, just PM me.

    • Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣
    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
