Help is this nut Left hand tread
 

Hi i need to take the rear wheel hub off my 1957 f350 could you tell me are the large nuts that hold the hub on left hand tread as i cannot undo it.Thanks whats the best why to crack it free a large socket id so what size thank you Pete from the UK

The lug nuts(that hold the wheels on) on the driver's side are left hand(1 1/16" socket, I think).
Everything else is standard thread on both sides.

Are you talking about the small axle nuts(1/2 or 9/16" socket) or the large bearing retaining nuts(over 2" socket.)?

Are you referring to the large nuts that hold the bearings in. They are not left handed that I know of but they do have a lock washer between them that you have to bend the tab back on to be able to remove the outer lock nut first. The inner (adjusting) nut shouldn't be that tight.
i don't know the size exactly, around 2 1/2 inches or so, I mean nearly 65mm! :)

Normal rt hand thread. I'm not really proud of it, but I always knock them around with a cold chisel. From the looks of most of them, I'm not the first owner to do this :-hair

Those nuts should be regular thread. Cold chisel and 3lb hammer is the only way I've ever gotten that nut loose. Go in about 1/4in from one corner and nice and easy start an edge. Once you've got a spot that you can push with, then give it a few good hits. Just make sure your not trying to turn the inside nut at the same time. I see on a previous post to bend the tabs back on the lockring, I forgot to mention that.

I have used a chisel and puch as well in days of old. Lately, if I need to buy a tool I buy a tool. I guess it gives me a reason to take a break when I don't have what I need!:)

Thank you to all.Its so nice to ask on here to get the help.I have now got them off and it looks like the last owners knocked them off.Would you have any idea who would sell the nuts as these look a bit to damaged now.And who would sell the tabs you bend over.If not i will have to get a machine shop to make some.But i know i will be waiting quite some time.

Don't use a sharp chisel or you risk destroying the shoulders on the nut. Actually a very dull chisel is a better choice of tools. I have seen bigger trucks with the left hand thread on the right hand side, long time ago.

Hi i have now got them off.I could use them again but if i could get some better ones i would fit them.Thanks Pete
