Well hoping to get the car up in the air tomorrow and see if there is any movement in the ring. Really need to check how eccentric it is. Looks kinda cocked but no sign of impact. Hoping I can heat it and tap it back square. As for securing it against further movement. I've been considering options from a large hose clamp/jubilee clip tightened alongside, some loctite cylindrical retaining compound or even a generous bead of sikaflex... Hmmmmmmm

Thanks James. Good tip, I will check, a crack may explain how it shifted. Just lucky it hasn't impacted the nut 

Thanks. I had hoped it was "shrunk" on. Will heat it and tap it clear of the nut head and back in line with the sensor. Plenty of info on the sensor/bracket but couldn't find anything on the ring. Pics online/assembly guide show it much closer to the rubber gaiter side of the driveshaft than mine. 

As the title says, is it just an interference fit or does it have a fixing that I can't see ? My speedo stopped working and it appears that the sensor ring has moved in (away from the diff) and is in danger of hitting the nuts on the carrier. It's no longer in line with the end of hall effect sensor in it's bracket. Any info would be appreciated.
