The ring is part of the CV joint. You need the CV joint, a new boot and the fastening clips.
Undo the big not on the end of the shaft before you do anything. Then remove the hub and shaft assembly. Pull the shaft out of the hub, very easy.
To get the CV joint off the drive shaft, cut the boot off, then hold the shaft vertically in a vice with the CV joint down, hold the end of the CV joint straight and give the face of the CV joint a good whack, make take more than one attempt, the CV joint should come away. Keep the snap ring and don't lose the silver collar. To re-assemble, boot on first, put the silver collar on the drive shaft then fit the snap ring, use the silver collar to compress the snap ring, slide CV joint onto shaft which will push the collar back releasing the snap ring to lock the shaft. Check that the CV joint will not pull off.
Fill the CV joint with the special grease it comes with making sure it's worked well into the bearings. Refit shaft to hub and put the big not on finger tight. Refit hub and shaft assembly. Tighten the big nut using about 4ft of scaffold pole:eek: I don't know the torque but it needs to be bloody tight:D

Oops, that's for the front, looks like you are doing the rear, sorry.

If the ring is split then it's not part of the CV joint,clean off the old ring and where it seats,warm up the new reluctor ring and tap it in place, known as sweating it on. Make sure it's seated in the right place,the joint should have a shoulder where it sits against..piece of pi$$

Yep it's definitely not part of it. There's a gap underneath, was able to hammer it with a chisel to crumple it to aid removal
 
I believe unless you want to cut the frame and lower the steering column its a dash out job:(

No need to cut. At least I don't think so. Undo the centre section and then bend the black ends out of the way and it looks like the whole box should split and lift. I cannot see where it splits though. I must have missed a screw or a bolt sonewhere because it is holding near the bottom. Unfortunately I ran out of time as I was taking my mother out this evening so I will get back to it later in the week or next weekend.
