Thread: A frame castellated nut - size?

Hi Lionel

I have forgotten the size but you can get a socket on and with a universal joint you can wiz it off in seconds with an impact drill/wrench.

I replaced my A ball joint with one with a grease nipple. It’s a little hard to get at to service but you can. Supposed to extended the service life of the unit… seems ok so far but is relatively new.

Cheers Simon

30mm

Just recently changed mine, same as Simon said....socket and impact wrench.... I have a Long Ranger fuel tank, which restricted access. Just put rear of chassis on axle stands, removed rear wheels, and lowered axle with jack. The only issue I had was getting the torque wrench on the nut to re tension at the end.

I gave up trying to get the torque wrench on, just used a bar and a length of gal pipe and was sliding around on the ground getting it as tight as possible and putting the pin in! No idea what torque it is..

On my vehicle it is NOT possible to remove the castellated nut with a socket - there's not enough space. Apparently with a Salisbury diff there is room to use a socket, but not with the Rover diff fitted to later TD5s.

Hence the ring spanner.

Hmmm, that really does throw a spanner in the works…. ;-)

Most ball joints seem to be 30mm spanner size (Maxidrive are 28mm from memory), I have a 2005 Td5 with a P38 rear diff and I had to shop for a socket that I could get on for quite a while. It is certainly a tight squeeze.I'll have a look later today what socket I used.

I couldn't for the life of me get the nut off the sals diff in my 2002 (also with long range tank), resorted to using a dremil and chisel which ended up costing me a new brake pipe aswell. If i have to do it again I would just unbolt from the top of the diff and do it all in a vice (not sure if you can do this with other diff types though?)

This style of impact socket was the only one that fitted. I think it also helped that is was a hex pattern which did not tend to round the edges of the nut.
