you can leave them attached to the hub quite easily mate.....bit more of a pain to work around them but its very possible; although with the wheels on I'm still not sure if you would be able to get enough access?

basically do it as you would normally, undo trackrod end balljoint, arb and lower arm balljoint.

if you can get at all those with the wheel on then you should be fine, pull em straight out the box and tie the driveshaft up so you dont knackers the joints..

good luck matey
