Thanks for all the advice & help, wheel now off, & front wing removed to fit a new oxygen sensor.
Can't believe the torque needed to undo the wheel, had to use a length of wood wedged in place to keep the brake pedal applied to prevent the wheel breaking traction under the torque.
Then I placed a length of wood between the trolley jack & the cross member to ensure load was evenly spread.
I also applied some white paint to the hub slot for the grub screw so that I can see the slot through the grub screw hole to ensure alignment when refitting.
