Quick update - the 3 Amigos have left the building (well the dashboard to be precise).
Been busy lately so the Freelander was left for a bit. Nice easy job - undo the driveshaft nut, then the two bolts holding the hub to the strut and release the driveshaft. Clean up the mounting, tap on the new ABS reluctor ring and put it back together.
Simples! And a total cost of less than two quid. If only the 75s were this cheap and easy to work on.
