take it from someone who has just changed my subframe and also my wishbone bushes. Its a pig of a job, lol.
The rear bush on the front wishbone is hard to locate when they have been polyed, especially on axle stands. I would happily pay a garage to fit them after the tow we had, it required using a ratchet strap, such as the ones used to hold loads to trucks, to pull the wishbone arm in as even a bar wouldnt quite do it, lol.
Bet the steering rack ones are a real sh!t, you would need new bolts and nuts from VAG for the rack as well as they shear when you remove them, only a couple of quid though.
