A frame castellated nut - size?

Hi,

I'll soon need to replace the A frame ball joint on my Defender 2004 TD5 Xtreme.

I want to replace the unit complete (with housing), but would like to undo the castellated nut & try to break the taper with the old unit in place before removing it.

Does anyone know the exact size of the spanner needed. There is only room for a ring spanner, unfortunately, & I'll have to buy one.

It is 28-30mm approx. (1 1/8 AF maybe?).

Any information would be appreciated.

Cheers,

Lionel

30mm. It doesn’t look it but there is room to get a 1/2” drive 30mm socket on there quite easily

1/2” drive 30mm 6 point socket with mods so it fits

not more 42mm in Hight and with 45 ground off drive end socket

My model doesn't have enough space between the diff casing to allow use of a socket. (Rover diff - not Salisbury). Seems to vary beween models quite a lot.

A good suggestion, but I'll try a 30mm ring spanner first, & if it won't loosen I'll probably resort to drilling the nut & a belt with the cold chisel to split it!

Ive just done mine and swapped for a gwyn lewis one.

Removed with a 30mm 1/2" socket but has to be done up with a 30mm ring spanner on a 90.

Jack the body high enough so the spanner doesnt foul on the tank.

Will add pictures

Thanks LandymanStefan,

My 2004 110 TD5 has a P38 rear diff, & the bracket which the 30mm nut attaches to is welded to the diff casing. (Looks like your 90 is the same). This removes the option of removing the whole thing & working with a vice on the bench. (Grrr!!)

A colleague on another forum has directed me to a Daytona 30mm impact 6 point socket which is 42mm in height & should fit. He has the same setup on his 2005 TD5 as on mine, so hopefully that will work.

Cheers,

Lionel

I got my impact socket in to remove it but when I comes to tightening there’s no chance. I bought 2 extra different shaped sockets, standard and and stubby impact one. Neither would go near it.

That's interesting! Why would you be able to undo the nut with a socket, but not be able to tighten the new one?

Was it something to do with the characteristics of the Gwyn Lewis replacement assembly? If so, that is disappointing, as I was thinking of ordering one for mine. Wink

Cheers,

Lionel

I think it’s just the position of the nut when it’s at the bottom of the thread. Nearer the bottom of the thread you’re closer to the axle and you can’t squeeze the socket in. When I was undoing it I can’t say I was on it square either just managed to blitz it off. Laughing
