Hi folks

Anybody know what thread the top ball joints are where they screw into the wishbone- wanting to fit locknuts and finding it difficult to match the thread.

Scott,

If you are using MK's wishbones then the thread should be M18x1.5

HTH

Nick

Scotlad,

had a similar problem very recently. MK have to get them specially made. They fit between the top ball joint and the wishbone. Should be some pics on our Photo Archive of Red Rocket. They cost a couple of quid each from MK I believe.

Sotlad,

I got mine from my local nut & bolt place for £1.50 each. If you like I could get you some and post them.

Nick

ah right. visiting MK next Saturday so i'll grab a couple then, or failing that i'll give Nick a shout and get them posted.

Thanks guys

This may be a stupid question but...

Why do you need locking nuts at all? Surely the ball joint can't unscrew itself from the wishbone?

doz@cougarracing do them at a quid each I think and lolo the same but there will be postage on that.

yours, Pete.

I've seen locosts built from as early as 1997 and nobody has ever used locknuts in this area,i think you migh tbe overkilling the engineering a bit here.
just put an M18x1.5fine nut on it

If youve got any contacts with the pneumatics companies, they use M18 x 1.5 locknuts on the bulkhead fittings.

surely there is no need to lock these?

as its in the thread and the only way it could chnage the camber setting while driving would be to disconnect the lower wisbone from the upright and then roate the upright around the ball joint ?

LOL ?

surely you dont need to put nuts on this ?

someone already said it helps prevent rattles wearing it out. Keeps the thread tight.

Ofcourse they use nuts,just no need for nylocs.

Bob is correct.

When an externally threaded part is screwed into another it is standard practice to use slim nut (referred to as a "locknut"...the two internally threaded parts are then locked against each other.....nylocks are not neccessary in this application and never have since the invention of screw threads......nylocks are for use when there is only ONE internally threaded part...i.e regular nut and bolt use.

It says locknut, not nyloc in the original post. If the thread isn't locked the joint can turn to an angle so it isn't level. The Americans do away with any confusion on this point by calling it a jam nut don't they Alan.

yours, Pete

sorry i was sure i read nyloc somewhere in the thread,maybe i need more food and sleep.
I'm on the verge of booking SVA so i'm in a world of mental inbalance right now

OK fine but what does mr SVA tester say about these.......

NEEDED or NOT NEEDED ?

That is the question.

is £2/£3 worth a possible sva fail ?

It wouldn't pass MOT without them, I asked.

yours, Pete.

Lock nuts (not Nylocs, they're lock-ing nuts) are mandatory for the reasons outlined above.
I (being an old fart) remember the days when the luck nut used to be supplied with the rod end in the same box.

I'm presuming thess lock nuts have to be protected for SVA because of sharp edges. How are people planning on protecting this and the remaining thread?
Heater hose, polyolefin shrink tube etc??

Cheers

Im going to put on a Dax style front bumpers, that saves putting anything on the front suspension.
