BWAHAHAHAHA, those prices are funny as heck.
Rear brakes are $39 for new rotors each, plus $50-$80 for some good pads. Hit up GSLRallySport a sponsor here for them, easy as hell job to do.
Radio antenna, $120 or so for a new genuine one, takes about 1-2 hours to do for the first time.
Sway bar link pins, about $50 for nolathane replacements, easy as piss to do.
Never done the others myself before, but CV shafts, Holden Commodore VT,VX,VY IRS CV Joint Drive Shaft (eBay item 380320245240 end time 29-Mar-11 15:55:58 AEDST) : Cars, Bikes, Boats. If Holden apprentices can do it in 2.5-3 hours (Its $120/h now isn't it) than a monkey can probably do it in less.
Depends on which wheel bearing as to the price.
Don't know what they mean by steering rack cover, maybe the boots? If so than its about $20 for new boots. I think it will need a wheel alignment after though, not sure?
Out of curiosity why are you still going to Holden for servicing? Still under warranty or something?
Honestly get yourself a Gregory's manual or something, will save a heap of cash. If you don't at least attempt the first three than I'm sorry you will have to hand in you Manly Man Card.
