new urethane bushes, do not please do not put the arms in with the old bushes in there..
undo the inner bolt, track rod nuts, sway bar mount, and strut bolts, then use a ball joint compressor or failing that a block of wood under the steering knuckle, and hammer out the rack end (last resort only please cos you might f*** it! )
