does anyone know what size this nut is?
I was thinking 32mm but if someone could confirm this for me before i put it up on stands & then find out i dont have the correct size socket.

 

anybody know?

 

Yup, 32mm

 

Can be a right BUgger to get off, you may want to actually loosen it with the tyre on and car on ground....i.e. jack it up, remove wheel, remove centre cap on wheel, bolt wheel back up and lower off car.....then loosen nut.

Hope that helps.

 

as above but have someone standing on the brake pedal makes life a bit easier.
