by the state of the oil round the hub i would be taking the nut off and fitting a new set of bearings and seal and give the planet gears a good wash out to i bet the bearings are braking up and in the past i have had to split the nut in half to get them off my be worth checking the king pins and fitting new axle drive shaft seals i no things start to get pricey and add up but its better than trying to find another axle and i would change the rest of the axle and hub oils to

Would it be left hand thread? What about heating it? Is a chisel and a good crack with a lump hammer out of the question? I know it's rough but shock can do wonders!

Hi, there is a special tool - a large 1" drive socket. i have seen people 'make' them, but there is an incredible amount of torque needed. Hitting it with a chisel, carefully may loosen it, but you could easily damage the shaft threads and possibly need a new nut. I think it is also a nylon locknut - in which case you would damage that - and you do not want the nut coming off when going dowhill or you may overtake your front wheel. i cannot help with the thread direction - it would say in a parts book ot the CASE IH parts website as the nuts would be different. I think they are the same and it just the standard thread.

You have the right idea with the tool you made. Nothing wrong with that, maybe try a T-bar with two people and scaffold pipes to undo it (3/4" drive or bigger, preferably) If it doesn't undo, then you will have to split it. Obviously, the weak point is where the slot is, so sharpen a good heavy chisel and wack it to split it, or warm it up there. It is a nylon lock nut. Unless you use it with some locking compound, then you should use a new one each time. ( You should officially use a new one anyway. Nylon locking collar is not meant to be re-used on this safety-critical fastener) It is normal right-hand thread. I wouldn't hesitate to split it and order a new one. Oh, and yes, that "lubricant" in the hub, yuck! It's a wonder the gears aren't junk. The bearings won't be great.

By the look of the surfaces there's been a lot of metal moving around and looks like it's turned the oil to grease. As said renew the nut at least.

I have a new nut ordered plus bearings so i dont mind the nut getting damaged.Its just to get the thing off.Im expecting the bearing to be in a bad way.
Also i have a spare axle with damage but the hubs are perfect so i will be replacing any bits that i need.
Thanks for the comments guys will let you know how i get on.

The oil you have been given should be fine. It's slightly thinner when cold than the stuff the manual recommends, but this isn't a bad thing.

What did the total bill run for parts? I have a leaking Carraro to do, but I think so long as it is working, I am better off to add some oil a couple times a year..

If it only needs oil adding a couple of times a year I think I'd be leaving well enough alone whatever the cost of the parts!

I suspect the price may alter dramatically depending on where you are able to get parts. For instance if I had one of these to do I know a local bearing place that hasn't failed to get a bearing or seal yet and the bearings would probably cost less than £50 - but getting them from a dealer would be a very different matter. If you know the right places things can often be done quite cheaply.

I have a decent place to get bearings and seals. I priced out the parts to do it a couple years ago at the dealer and was given the "No Longer Available" story. I suspect the counter guy just didn't want to look them up.

It leaks enough that it s usually wet around the back side of the hub. The dirt sticks to the leaked oil on the inside of my rims. It is generally ugly but still works(except I need to pull the transmission because of a bad bearing).

Cant remember exactly what the wheel bearing was.Think was about €80
small oil seal was €22.big seal was €60.bearings for bearing pin on swivel hub was €40
Oil €12 , The castellated nut was priced at €97 but didnt turn up in the end.
The shop told me they have never replaced these nuts and they do these seals on a regular basis and always put the old one back.
So old nut went back on with locktite. I hope this will be good enough
I will be keeping a close eye on it for a while
The tool i made was great both for opening and reassembling.was used with 3/4 sockets.
My big concern was the high torque setting as i have nothing to measure this so a long bar was used and its as tight as i could get it

Don't worry, long bars are usually perfect!
