Pads & discs £150 max
Cv boot remove and replace (ask them to use a stretchy boot saves on labour time) £50 max takes about 25 mins
Anti freeze £40 drain and re-fill
Rear bearing £90 max
Anti roll bar link about £8 to buy and two nuts need undoing to fit it the wheels are already off for pads and discs so £40 max I'd say including parts
