Hi guys well had a quick search but cant find the answer.
Looking to change the rear hubs on my TD5 due to 3 amigos.
Can anyone tell the what size the hub nuts are, just want to make sure I have the correct size socket in 3/4 drive before I start.

Thanks

Hi Ruffday,

Have a look here.
http://www.discovery2.co.uk/fronthub.html

I believe they are the same size. Front and rear. although I understand form also searching recently, there is also a 36mm stake hub nut also available with aftermarket hubs.

Cheers

Thanks for that link. Great write up so looks like 32 mm with a poss 36mm for aftermarket nuts.

Hi Ruffday.

I was looking for the socket size myself a few days ago, and found a reply from the Guy who wrote that write up in this forum.

I also found mention of 33 / 34mm nuts in another topic , So I am not sure how we are meant to know what size socket you will need until you have them in your hand.

Let us know what size you get when you order yours.

Cheers

Front hub tutorial here http://www.discovery2.co.uk/fronthub.html says the front is 32 mm but if I remember correctly the replacement hub nut I bought was a different size. You will need a big breaker bar to undo it, I ended up buying a 3/4 drive socket set. Not sure if the rear is the same as I haven't had to do mine (famous last words)

Headtester,

Do you remember what size it was?
Having looked at the nuts available on fleabay, it appears if you look closely that you can see the nut size is slightly different.

Mine are 32mm front and rear, breaker bar with a length of scaffold bar helps. Retighten until you are red in the face !

Stake nuts are CDU1534L and front and rear are all 32mm (if you have and use the correct nuts, which I'd say is likely!)
I bought a big torque wrench second hand on eBay. Used it 5 times now so paid for itself in money saved on diy hub changes!

Eg http://www.rimmerbros.co.uk/Item--i-CDU1534L

Very strange why after market are so much bigger (36mm)

Big torque wrench, Got that covered.

Now have to order the 32mm socket 6 sided and a short extension.

ruffday · May 20, 2016

Checked the rear and they are 32mm on mine so need to get a 3/4 socket.
Already have a 3/4 bar and scaffold pole. and at 17 stone it will be quite tight.
Thanks for the help guys.

Sorry, think it was 32 mm but I can't be certain. I bought one of these socket sets for a bit under £40. Not top class quality but fine for the job.

ruffday · May 21, 2016

That's not a bad price for the kit.
I already have a good selection of tools but not had much reason to buy a 3/4 kit.
But you can never have too many tools.

For information and delectation,

I checked mine at the weekend , they are all 32mm on the vehicle currently.

BUT:

Just had a reply from bearmach, tech service.
Question:

Can you please tell me the socket size needed for the Discovery 2 hub nut , I believe it is CDU1534L . Thanks

Answer:

I believe it is 36mm

Maybe something to keep in mind. It would appear as discussed before, there are at least two different sizes, 32mm which are the original size and 36mm which are aftermarket.

Cheers

Bought a nut, too big for my socket, looked up part number. bought a 36mm as well

Put a little heat on the nut, this will help break the Loctite!! I always use 6 sided sockets on tight stuff the 12 point sockets can chew the corners
