how difficult is this to change?

i half a ALK fitted, and i have allready swapped the front ARB bushs, the car has now done 90k miles and i think its probably about time the front wishbones were tidied up

i suspect one of them isnt fully true in shape, so i am planning on buying another set and fitting the bushes, then one day swapping them over for less hassle

do you need to press them on or anything?

On my Sti v3 with allow w/bones:
The rubber bush was cut-out most carefully to saw through the thin outer sleeve and so collapse the bush and it almost fell out of the arm. Hard work! (w/bone off the car!)
I installed poly bushes so easy, but to put a fresh factory bush in you will need a press and the right mandrels.
The bush comes in a thin steel outer sleeve.
Cheap to get done as you have done all the hard time consuming work. If the bush is orientated to the right position of the w/bone then maybe a Subaru dealer is best used?
