"Thank you" everyone for all the help and advise. I've completed this install today.
During reassembly of the passenger rear axle I noticed grease was all over the bolt holes and surrounding connection points. (attached photo) Can someone confirm if this is normal or if I have to now purchase a cv joint replacement kit.
One thing I might add. I've started the car and move it to "D" and now when I put it in park it makes a grinding sound.
