Thanks Alex,
Just found a pdf with some instructions. Look pretty straightforward until I spotted the bit;
8. Use a ball joint remover (SST) to remove steering outer socket from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball joint remover (SST) from coming
off.
9. After removing upper link, transverse link, compression rod and cotter pin at steering knuckle, loosen mounting nut.
10. Use a ball joint remover (suitable tool) to remove upper link, transverse link and compression rod from steering knuckle. Be
careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
11. Remove steering knuckle and wheel hub and bearing assembly fixing bolt.
12. Remove wheel hub and bearing assembly from steering knuckle.
Looks like could take a couple of hours following the manual. Do you think I can carry this out then without removing he ball joints?
Cheers
Dave
